Q

Goals of Palliative Care (4)

A
  • Improve quality of life (better relief of symptoms esp. Pain, Dyspnea, N/V, Fever and Infection, Edema, Anxiety, Delirium, Comfort) – does not mean pt does not want any treatments
  • Allow client to experience a “good death”– doing what patients wishes and desires are to promote peaceful and meaningful death
  • Avoiding a Bad death: not following patient’s wishes; isolation, pain; death w/o dignity
  • holistic care for all needs of patient and family

Q

Prevention of Sedation Dependence: Daily Sedation Interruption

Process (4)

A
  • Turn off medication (propofol wears off fast; Versed/midazolam wears off slow) once a day
  • Assess LOC and neurologic function of patient after awareness attained
  • if agitated, change in VS, dysrhythmias, restart to prevent complications – MONITORING = VERY important to prevent harm during withdrawal
  • After interruption, determine next plan of care (may reduce dose to avoid dependence; may discontinue sedation if able to be off > 4 hrs

Symptom Management for Palliative Care - Pain (4) - NV (2) - Fever and infection (2) - Edema (2)
Pain (most feared) - nonopioids then transfer to opioids (morphine; Fentanyl if delirius) as needed - May need to use rectal, transdermal, IV or SubQ route as ability to swallow is lost ( Avoid IM b-c variable distribution and painful) - Avoid unnecessary treatments - Nonpharmacological: massage (not on tissue damage or if bleeding disorder), music, therapeutic touch, imagery, aromatherapy (lavender, chamomile, sweet marjoram, dwarf pine, rosemary, ginger) N/V (Cause: intestinal obstruction, increased ICP) - Antiemetics (prochlorperazine, ondansetron, dexamethasone, metoclopramide) - Avoid decompression b-c uncomfortable Fever and Infection - Antipyretics - Continue antibiotics Edema or fluid overload - Diuretics (know kidney function) - Avoid dialysis
26
Symptom Management in Palliative Care (Dyspnea) Nonpharmacological (4) Pharmacological (4)
Nonpharmacological - Raise HOB - Electric fan (increases ambient air flow) - Wet cloth to face - Encourage imagery and deep breathing Pharmacological - Oxygen (give regardless of O2 sat b-c dyspnea is subjective) - Give morphine (b-c alters air hunger perception, reduces anxiety and muscle tension, and reduces pulmonary congestion via pulmonary vasodilation) - Give versed (midazolam) if unable to take opioids - If bronchospasm give bronchodilators or corticosteroids
27
End of life issues - CPR (3) - DNR or DNI (3) - withdrawal or withholding of treatment (2)
CPR - Family presence is important to facilitate closure during CPR or invasive procedures - Done for everyone unless DNR - Can be painful, unsuccessful or result in worsened condition DNR or DNI - DNR does not mean stop caring for patient or stop all life sustaining treatment - DNI (do not intubate)-may still want CPR - Must be signed by HCP Withdrawal or withholding of treatment - Prepare family for what to expect - implement comfort orders prior to treatment withdrawal
28
End of life care: best practice for involving family in decision making (5)
- Early and ongoing discussions (daily rounds, family meetings) - Informed consent necessary (explain things in language family can understand) - Patient’s wishes should guide discussions about withdrawal of care - Ask about family’s emotional state and acknowledge expressions of emotion - take into account cultural and spiritual practices and respect them
29
Stages of Withdrawal of Treatments in End of life care (5)
- Removal of routine interventions (labs, imaging, cardiac monitoring) --Monitors may be kept to adjust medication amounts in symptom management or for families to verify cessation of electrical activity - Removal of respiratory support devices (need DNR prior to withdrawal and withdraw paralytics first) - turn off pacemaker and ICD (may interfere w/ death pronouncement, or cause discomfort and distress due to shocks firing) - withdrawal of artificial nutrition and hydration (family may be concerned but excess nutrition and fluids can prolong suffering) - Provide symptom management in accordance w/ symptoms
30
Signs of Approaching Death Vision Speech Circulation (3) Respirations (2)
Vision - No eye movement, staring, dilated and fixed pupils Speech - Difficult to understand, unable to speak as LOC decreases Circulation - Cold, mottled and cyanotic extremities r/t decreased peripheral circulation, poor tissue perfusion and heat loss - HR increases, irregular, gradual decrease until stops - BP drops Respiration - Shallow, apnea, labored -> Cheyne-stokes (apnea then rapid) - Death rattle (loud, wet respirations from Mucus collection)
31
Signs of Approaching Death Muscle tone (2) GI and GU (2) LOC (2)
Muscle Tone - Limp body/weakness - jaw drop GI and GU - Anorexia - Urinary/Anal incontinence LOC - lethargic, unresponsive, coma) drop - Increased sleep
32
Care for Changes r/t Approaching Death Speech Circulation (2) Respirations (3)
Speech - talk to pt as you normally would Circulation - apply blanket - no electric blankets or heat packs Respiration - Positioning ( Elevate HOB, turn head to side) - give anticholinergics or scopolamine to decrease secretions - oral suctioning not helpful
33
Postmortem Care (7)
- Treat body to privacy, respect and gentleness - Close the patient’s eyes and Insert dentures if the patient wore them. - Straighten the patient and lower the bed to a flat position w/ pillow behind head - Wash the patient, comb hair, clean room - Place waterproof pads under the patient’s hips to absorb any excrement. - Allow the family or significant others to see the patient in private and to perform any religious or cultural customs they wish (e.g., prayer, eye closing, washing). - Ensure that the nurse or physician has completed and signed the death certificate prior to morgue transfer
34
Old categories (4)

41
Older Adults: Inadequate or Decreased Nutrition Contributing factors (8)
- Diminished sense of taste, smell (Results in loss of desire for food) - Inappropriate/unbalanced foods (fast foods) - Excess meds and OTC drugs (can decrease appetite, affect food tolerance and absorption, and lead to constipation) - Tooth decay, tooth loss, poorly fitting dentures (r/t inadequate dental care and calcium loss)- may lead to avoidance of nutritious foods - reduced income - Chronic disease/ Fatigue - Decreased ability to perform ADLs - Loneliness, depression and boredom (may lead to lack of eating and weight loss)
42
Older Adults and Hospital Patients: Inadequate or Decreased Nutrition Care for inadequate nutrition (7)
- Perform nutritional screenings on the 1st day of pt. admission (include Nutritional hx, wt., ht., and BMI) - Do an oral exam to understand why patient may only eat soft/low fiber foods - Collaborate w/ RDN about the patient's nutritional status - Collaborate w/ SLP about problems swallowing or chewing - Encourage to use herbs instead of salt and sugar b-c may overuse them - Get social work involved for food bank programs - manage symptoms that may impair nutrition (pain w/ analgesic; NV w/ antiemetic)
43
Older adults: Inadequate or Decreased Hydration Contributing factors (3) Care (4)
Risk factors - less body water - decreased thirst sensation - Limiting fluid intake in evening due to decreased mobility, diuretics, and urinary incontinence Care - Incontinence increases w/ dehydration b-c concentrated urine irritates bladder - Drink 2 L of water a day plus other fluids - Avoid excess caffeine and alcohol - Know s/s of dehydration (dark urine, weight loss, poor skin turgor, dry mucus membranes)
44
Constipation Causes (2) Impacts (5)
Causes: inadequate nutrition or hydration; drugs Impacts: pain, depression, anxiety, decreased social activities, small or large bowel obstruction
45
Older adults: Decreased Mobility Care (5)
- Assess older adults in any setting about hx of exercise and any health concerns - Teach importance of physical activity 3-5x a week for at least 30 minutes - Encourage sedentary adults to slowly start their exercise programs - If patient is homebound, focus is performing ADLs - walking and swimming are good choices (walking is best because it is weight bearing and can help prevent osteoporosis and build bones)
46
Older adults: Benefits of Regular Exercise (6)
- Increased mobility, muscle strength, and balance (so decreased falls) - Better sleep - Reduced or maintained body weight - Fewer depressive symptoms (improved well-being and self-esteem) - Improved longevity (Reduced risk of Diabetes, Dementia, CAD) - Decreased risk for constipation

49
Accidents: Falls in Older Adults Risk factors for falls (8) Fall risk Assessment (3)
Risk factors - Hx of falling (most important predictor of falls) - Multiple illnesses - Generalized weakness or decreased mobility - Changes in sensory perception (r/t age or drugs) - impaired body orientation r/t decreased sense of touch -> decreased reaction time - Urinary incontinence or nocturia - Communication impairment (disorientation, confusion) - Alcohol/substance abuse Assessment (fall risk assessment) - Observation of Gait (wobbly?); Footwear (closed toe? Sturdy?); assistive devices (cane? Walker? Glasses?)---Do they use them? - Past medical hx (Diabetic neuropathy?, arthritis?, peripheral neuropathy?) - Drug assessment (Drug side effects?) i.e. Antihypertensives and orthostatic hypotension; Opioids and CNS depressant effects of drowsiness and acute confusion
50
Accidents: falls Impact of falls (2) Prevention (8)
Impact of falls: fractures and fallphobia (esp if osteoporosis) Prevention - Ensure hydration b-c dehydration can cause incontinence due to bladder irritation - RN communicate hazards on their health literacy level - Safeguards (handrails, grab bars, slip proof rugs, adequate lighting) - No scatter rugs, slippery floors, clutter - Pt avoids going out on bad weather days (slippery or icy) - ask for help when needed esp. toileting - use assistive devices i.e hearing aids, glasses, walker, cane, - keep bed low and locked
51
Older Adults: Drug Use Concerns (3)
- Intolerance to standard drug dosages (use “Start low and go slow” policy) - Opioid Use (increased due to use for acute and chronic conditions w/ persistent pain) - increased risk of adverse drug events due to polymedicine/polypharmacy
52
Older adults: Age-related changes of Pharmacotherapy - Metabolism (3) - Excretion (3)
Metabolism (monitor liver function tests) - Decreased liver size - Decreased liver blood flow - Decreased serum liver enzyme activity Excretion (get renal function test esp. Crt clearance) - Increased BUN and Crt - Reduced renal blood flow - Reduced GFR and creatine clearance (leads to slower excretion; decreases by 6.5 mL/min per decade of life)
53
Older adults: Age-related changes of Pharmacotherapy - Absorption (3) - Distribution (4)
Absorption - Decreased GI motility - Decreased GI blood flow - Increased gastric pH Distribution - Smaller amount of total body water - Decreased albumin level - Increased ratio of adipose tissue to lean body mass (leads to increased storage of lipid-soluble drugs in tissue vs plasma) - Decreased cardiac output
54
Older adults: Factors for improper self-administration of drugs (7)
- Poor communication with HCP r/t poor explanations due to educational limits, language barriers or difficulty hearing and vision - Make errors (Forget to take; Duplication (think 2 is better than 1); use wrong drugs - Take OTC drugs that interact with prescribed drugs (Ex. Clopidogrel, aspirin, warfarin for anticoagulation, ibuprofen for arthritis and garlic for hypertension = bleeding risk) - Discontinue drug therapy due to cost, fear of dependency or side effects) - use leftover drugs from previous illness - Borrow from others - Use more than one pharmacy
55
Older adults: Medication assessment and health teaching (6)
- Obtain complete drug list (OTC, prescribed, herbs, supplements) - Highlight all drugs that are part of Beers criteria ( drugs where harm > benefit for elderly (ex. Benadryl, ketorolac) - Assess for duplicate drugs (Ex. Warfarin from two pharmacies) - Give verbal and written information at appropriate knowledge level - Encourage to take drugs exactly as prescribed (do not share or borrow drugs) - Be Aware of common adverse drug events (ADEs) (Hypotension from HTN drugs; Edema; Syncope; Dehydration from diuretics)
56

57
Older adults: Tips for better drug self-administration (5)
- Encourage use of pill boxes or associating pills w/ daily events - Use large print on drug label for poor vision - Write drug regimen on bottle - Colored labels - Easy to open bottle caps for limited hand mobility and strength
58
Older Adults: Depression What is it? Primary vs Secondary
-Mood disorder having cognitive, affective, physical manifestations (sleep disturbance, fatigue, increased pain; worsening of current problems; suicide risk) Primary: lack of neurotransmitters (serotonin and norepinephrine) Secondary or situational: r/t sudden change in life such as illness or loss (conditions: stroke, arthritis, cardiac disease)
59
Older Adults: Depression Assessment Treatment (3)
Assessment - Geriatric Depression Scale (15 yes or no questions; > 10 = possible depression) Treatment - SSRI (takes 2-3 weeks to start working) - TCAs have anticholinergic properties and should not be used (side effects: acute confusion, severe constipation, urinary retention or incontinence) - Nonpharmacological: psychotherapy; reminiscence, music therapies
60
Older Adults: Dementia What is it? Prevention (4)
- Slow, progressive and chronic global impairment of intellectual function Prevention of cognitive changes in older adults - Cognitive training (learning new skill) - Physical and mental activity - Social engagement - Proper nutrition
61
Older Adults: Alcohol Use Impacts (5)
- Increase risk for falls, other accidents - affects mood and cognitive ability ( may lead to Isolation, depression, delirium) - Bladder and bowel incontinence - Complications of chronic diseases (DM, HTN, GERD) - Poor nutrition r/t drinking > eating
62
Older Adults: Alcohol Use CAGE Screening (4)

COPD (respiratory acidosis), DKA (metabolic acidosis)
69
ABGs: Normal values (4)
- pH 7.35-7.45 - CO2 35-45 (Ventilatory failure if > 50) - HCO3- 22-26 - PaO2 80-100 mm Hg (never should be < 40)
70
ABGs: Compensation equations (3)
- ph abnormal + one abn. value = uncompensated - ph abnormal + two abn. values = partial compensation - ph normal + two abn. values = full compensation (determine primary disorder by seeing if pH on acidic (7.35-7.4) or alkalinic side (7.4-7.45) of normal)
71
Other ABG Components - O2 sat-- (2) - Oxygen content (CaO2)-- (2)

72
Other ABG Components - Base excess/ base deficit (4)
- normal range -2 +/- 2; -2 to 2) - Identifies non respiratory contributors to acid-base balance - <-2 base/bicarb is deficit (metabolic acidosis) - >2 base/bicarb is excess (metabolic alkalosis)
73
Other ABG Components - PaO2/FiO2 ratio called P/F ratio (4)
- Lower the number = worse the lung function (want > 286) - Estimates intrapulmonary shunting (portion of venous blood that flows to lungs w/o being oxygenated which leads to non functioning alveoli) - PaO2: partial pressure of oxygen dissolved in arterial blood plasma 80-100 mm Hg - FiO2: fraction of inspired oxygen 21-100% (21%= room air; 100% possible via vent or ambu)

- feeding tube usually for 7-10 days post-op and removed when swallowing is safe per Swallow study - PEG > NGT to prevent aspiration - give diet high in protein and calories - small amounts of food at a time - may need thickened liquids  - collaborate w/ RDN and SLP b-c at risk for aspiration, speech, and nutritional problems
91
Aspiration: Risk factors (4)
- surgical changes in upper respiratory tract w/ laryngectomy - NGT - Difficulty swallowing r/t tracheostomy tube fixing larynx in place and cuff interfering with passage of food via esophagus - cuff pressure < 20 on trach tube (may partially deflate for easier swallowing)
92
Prevention of Aspiration Care (5)
- tuck chin when swallowing - use supraglottic swallowing (Valsalva maneuver and swallow twice to clear food that may pool in pharynx; exaggeration of normal protective mechanisms) - observe for aspiration or aspiration pneumonia and report immediately (aspiration not possible after total laryngectomy b-c airway totally separated from esophagus) - NO oral intake until swallow study done - collab w/ SLP and RDN

100
8 emergency situations w/ chest tubes
- Tracheal deviation from midline - Sudden onset or increased intensity of dyspnea - O2 sat <90% - Drainage greater than 100 mL/hr, fresh blood, sudden increase in drainage - Visible eyelets on chest tube - Chest tube falls out of the patient’s chest (cover the area with dry, sterile gauze; leave one side out so air can continue to escape chest and prevent tension pneumothorax) - Chest tube disconnects from the drainage system (put end of tube in a container of sterile water and keep below the level of the patient’s chest) - Drainage in tube stops (in the first 24 hours)
101
Older Adults: Age-related changes in Gas exchange (9)
- Sarcopenia (age-related muscle atrophy) and weakened respiratory muscles - Decreased chest wall movement (stiffens) and size - Air trapping = increased residual volume causing thinned and enlarged alveoli - Reduced sensitivity to hypoxia and hypercarbia - Decreased pulmonary reserve - Decreased pulmonary perfusion capacity - increase Dyspnea - Difficulty coughing up secretions r/t decreased cilia beat frequency in airways - Decrease in ability to protect against environmental injury and infection (r/t decreased T-cell, nutrition, swallowing ability, and mucociliary clearance)

109
Tension Pneumothorax Process (3) Cause (2) Labs/diagnostics (2) Interventions (2)
Process - Air rapidly enters pleural space and cannot escape - Lungs collapses and mediastinum shifts to opposite side due to pressure of air - Air compresses blood vessels and heart which limits venous return and reduces cardiac output and gas exchange Cause - blunt chest trauma for accident or invasive procedure - barotrauma from vent Labs/Diagnostics - chest x-ray - ABG: hypoxemia and hypercapnia Interventions - Oxygen with PEEP (positive end expiratory pressure) needed - chest tube in pleural space to remove air or fluid, reinstate negative pressure, expand collapsed lung)

152
Artificial Airway: Humidification When? Purpose (3)
Humidify oxygen if > 4L w/ sterile water Purpose - Prevent drying and irritation of respiratory tract - prevent undue body water loss - Facilitate secretion removal (thick, dry secretions can occlude airway and increase risk for infection)

- Hyperoxygenate with 100% oxygen for 30-60 sec prior to suctioning and 60 seconds after suctioning - Use < 150 mm HG of suction to reduce hypoxemia, atelectasis and airway trauma - Limit number of times patient is suctioned - Suction 10-15 secs continuously on the way out to reduce hypoxemia, airway trauma, cardiac dysrhythmias (Intermittent suction during withdrawal leads to secretion dropping) - Suction mouth or nose after suctioning artificial airway
155
Artificial Airway: Suctioning Indications (6)
- Rhonchi or wheezes (usually not for crackles) - Coughing - visible secretions in airway or indicated by dyspnea - Sawtooth pattern on flow-volume loop on ventilatory - Increased peak airway pressure on ventilator - Acute respiratory distress (increased RR (indicates hypoxia), HR; restless; decreased O2 sat)
156
Mechanical Ventilation: Physiological Purpose (4)
- Support cardiopulmonary gas exchange (alveolar ventilation and arterial oxygenation - Increase lung volume (end expiratory lung inflation and functional residual capacity) - Decrease work of breathing - Assist with lung healing
157
Mechanical Ventilation: Clinical Purpose (7)
- Relieve respiratory distress (hypoxemia, respiratory acidosis, muscle fatigue - Prevent or reverse atelectasis - Permit sedation and neuromuscular blockade - Reduce ICP - Decrease oxygen consumption - Stabilize chest wall - Protect airway
158
Mechanical Ventilation Definition Indications (4) Types (2)
Definition: process of using an apparatus to facilitate transport of O2 and CO2 b/w atmosphere and alveoli to enhance pulmonary gas exchange Indications: Ventilation, oxygenation, airway and lung protection, secretions Types of ventilators - Positive-pressure: intubated and on machine via ETT or Trach; mechanical drive to force air into lungs - Negative-pressure: on machine but via mask; decrease atmospheric pressure around thorax to initiate inspiration
159
Mechanical Ventilation Variables (4) Variable Mechanics (4)
4 variables managed: time, flow, volume, pressure Variable mechanics - Trigger variable: initiates change from exhalation to inhalation (i.e time, pressure, flow) - Limit variable: sustains inspiration but does not end it (i.e. flow, volume, pressure) - Cycle: variable that ends inspiration (i.e any of the four variables) - Baseline: variable controlled during exhalation
160
Basic Ventilator Settings - Modes (3) - Rate - Tidal Volume - PEEP (2) - FiO2 (2)
Mode of ventilation - Assist Control (AC) - Synchronized Intermittent Mandatory Ventilation (SIMV) - Continuous Positive Airway Pressure (CPAP) Rate: respiratory rate (6-30 breaths/min) Tidal volume (VT): volume or size of the breath (6-10 mL/kg (4-8 mL/kg in ARDS) Positive-end expiratory pressure (PEEP) - amount of pressure remaining in the lung at the END of the expiratory phase; keeps alveoli from collapsing (3-5 cm H2O) - Risks of too much PEEP: barotrauma, decreased venous return FiO2 - fraction of inspired oxygen (Range: 21%-100%) - prefer <50% to maintain O2 sat > 92% and PaO2 > 60 mm Hg
161
Ventilator Modes: Assist/Control (Continuous mandatory ventilation) - How it works? (2) - Indications (2) - Care (2)
How it works - Delivers a “machine breath” every time, whether the pt. triggers the breath or the ventilator initiates the breath (time-triggered) - patient cannot generate spontaneous volume or flow rate Indications - Volume controlled AC if weak respiratory muscles but spontaneous breathing (Risk for volutrauma) - Pressure controlled AC if decreased lung compliance, increased airway resistance or risk for Volutrauma (Risk for hypercapnia) Care - Hyperventilation risk if patient increases their respiratory rate - Sedation may be needed to limit # of spontaneous breaths
162
Ventilator Modes: Synchronized Intermittent Mandatory Ventilation (SIMV) - How it works? (3) - Indications (3) - Risk
How it works - Delivers a pre-set number of breaths at a set volume or pressure and flow rate. - Allows the patient to generate spontaneous breaths, volumes, and flow rates between the set breaths. - Detects a patient’s spontaneous breath attempt and doesn’t initiate a ventilatory breath – prevents breath stacking (A/C does not prevent breath stacking) Indications - Volume controlled if weak respiratory muscles but spontaneous breathing - Pressure controlled if decreased lung compliance, increased airway resistance or risk for Volutrauma (Risk for hypercapnia) - used for weaning Risk - May increase work of breathing and promote respiratory muscle fatigue when used for weaning
163
Ventilator Modes: Pressure Support How it works? (2) Use Risk Pros (3)
How it works? - Positive pressure applied only on patient- initiated breaths on inhalation to augment efforts (similar to PEEP but only on inhalation vs. expiration) - Patient's lung mechanics and efforts controls rate, inspiratory flow, and tidal volume Use: for pt w/ stable respiratory drive to overcome mechanical resistance Risk: Hypercapnia Pros - Reduces work of breathing - increases ventilatory synchrony - Can be used with SIMV or CPAP
164
Ventilator Modes: Continuous Positive Airway Pressure (CPAP) How it works? (3) Indication (3)
How it works? - Positive pressure applied during spontaneous breaths (no ventilator breaths in PEEP or CPAP mode) - Pt controls rate, inspiratory flow, tidal volume - Similar to pressure support but without the additional inspiratory pressure Indication - used with masks for sleep apnea (negative pressure) - used with ventilator (positive pressure) - used for weaning
165
Ventilator Modes: Continuous Positive Airway Pressure (CPAP) Pro (2) Risks (3)
Pro - Increase functional residual capacity - Improve oxygenation via opening collapsed alveoli at end of expiration Risks - Decreased cardiac output - Volutrauma - Increased ICP
166
Mechanical Ventilation: Respiratory Complications (5)
- Increased secretions (care: Suction PRN) - Oxygen toxicity (Continuous oxygen > 50% for > 24-48 hrs may injure lung and reduce tissue integrity) --Care: notify HCP if PaO2 > 90 mm Hg - Respiratory muscle weakness - Ventilator-Associated Pneumonia - Ventilator induced lung injury
167
Mechanical Ventilation: Complications CNS GI (3) Cardiac Psychological (2)
CNS - Increased ICP r/t decreased cerebral venous return GI (prevent: NGT decompression, appropriate cuff inflation) - Gastric distention r/t air leaks around ETT or trach cuff and overcomes resistance of lower esophageal sphincter - Vomiting r/t pharyngeal stimulation from artificial airway - Hypomotility and constipation r/t immobility and paralytic agents, analgesics, sedatives Cardiovascular compromise - Decreased Cardiac Output r/t decreased venous return to right side of heart Psychological complications - need for alternative communication - Patient ventilator dyssynchrony (Risks: auto-PEEP, psychological distress, decreased effectiveness) Care: ventilator accommodates patient’s spontaneous breathing pattern OR patient is sedated
168
Mechanical Ventilation: Oxygen Toxicity Early signs (4) Late signs (5) Care
Early s/s: dyspnea, nonproductive cough, sternal chest pain, GI upset, crackles Late s/s: decreased vital capacity and compliance; hypoxemia, pulmonary edema, hemorrhage, hyaline membrane formation and atelectasis Care: notify HCP if paO2 > 90
169
Ventilator-induced Lung Injury Causes (4) Care (3)
Causes - Barotrauma r/t too much PEEP - Volutrauma r/t too much tidal volume - Atelectrauma r/t shearing r/t repeated opening and closing of alveoli - biotrauma r/t inflammatory-immune response (Leads to ARDS) Care - keep pressure at 32 or below cm H2O - use PEEP - tidal volume of 6-10 ml/kg

172
Ventilator Assessment (4)
- Assess settings and do they correlate with presentation (any desynchrony?) - High pressure alarms = airway obstruction b-c patient ventilatory desynchrony, airway resistance or kinked tubing - Low pressure alarm = leak or oxygen not connected - If vent malfunctions, disconnect patient from vent and Ambu bag patient
173
Mechanical Ventilation - Patient assessment (3) - Labs/diagnostics (3)
Patient assessment - Listen to patient and breath sounds - Assess symptoms esp. pulmonary system (subQ emphysema, SOB, agitation, pain, work of breathing) - Assess placement and securement of ETT or trach Labs/Diagnostics - ABGs - Chest x-ray - Pulmonary function tests (Vital capacity, minute ventilation, peak inspiratory pressure, tidal volume (how much exhaled))
174
Ventilator-Associated pneumonia Definition Risk factors (5)
Development of pneumonia 48-72 hrs after endotracheal or other artificial airway insertion intubation b-c tube bypasses normal defense mechanisms of lung Risk factors - severe illness - increased age - presence of ARDS or malnutrition - naso intubation b-c promotes aspiration - Gastric alkalization by enteral feeds and meds b-c promotes bacterial growth
175
Prevention of VAP (7)
- Hand hygiene - Elevation of HOB (30-45 degrees) to prevent GER and aspiration - Daily “sedation vacations” and assessment of readiness to extubate - Stress ulcer prophylaxis - DVT prophylaxis - Daily oral care (teeth, gums, and tongue) with chlorhexidine q2h - Adequate endotracheal tube cuff pressure (Keep at 20cm H20-decreases aspiration)
176
Weaning Methods - SIMV (2) - PSV - spontaneous breathing trial (4)
Synchronized Intermittent Mandatory Ventilation - Gradual transition from ventilatory support to spontaneous breathing (slowly decrease rate until 0) - Get ABGs 30 min after trial PSV - Gradually decrease pressure support while maintain tidal volume until 5 cm H2O support achieved Spontaneous breathing trial - Remove from vent and use T-piece for spontaneous breaths OR just stop mandatory breaths on vent - Add CPAP to prevent atelectasis and improve oxygenation - Add PSV to augment inspiration - If successful, consider extubation or changing to uncuffed tube
177
Long-term Mechanical Ventilator Dependence: Factors - Physiological (4) - Psychological (3)
Physiologic factors - Decreased gas exchange (ex. V/Q mismatch, anemia, hypoventilation, heart failure) - Increased ventilatory workload or demand (ex. Metabolic acidosis, decreased lung compliance, increased airway resistance, abdominal distention) - Decreased ventilatory drive (ex. Respiratory alkalosis or metabolic alkalosis, hypothyroidism) - Increased respiratory fatigue (ex. Malnutrition, Psychologic factors - Lack of motivation and confidence - Conditions that interfere with breathing pattern control (ex. Anxiety, fear, dyspnea) - Delirium
178
Weaning: Readiness assessment (6)
- spontaneous breathing trial - daily screening (stop sedation 1 hr prior to screening) - physiologically ready (hemodynamically stable, lungs capable of ventilation, original condition corrected) - psychologically ready (LOC stable - Decrease work of breathing via suction, HOB raised, sedatives for anxiety - interdisciplinary approach (PT for mobility)
179
Long-Term Mechanical Ventilator Dependence Description Classifications (3)
Description: assistive ventilation required longer than expected given the pt’s underlying condition Levels - Simple: weaning terminated within 1 day of attempt - Difficult: completed > 1 day or < 1 week after first attempt - Prolonged: not terminated 7 days after first separation attempt
180
Weaning: Process Initiation (3) Progress Intolerance Outcome (2)
Initiation - start in morning - Give patient explanation on process and sensations - Closely monitor patient for any difficulties Progress: measure % of ventilatory support required or amount of time patient goes w/o vent Intolerance: show s/s of respiratory distress (dyspnea, accessory muscle use, restlessness, anxiety, change in facial expression, VS changes (HR, BP, RR) Outcome - Complete = able to spontaneously breath for 24 hrs - Incomplete = unable to wean and may go home on vent
181
Mechanical Ventilation: Drug Therapy - mucolytics - bronchodilators - steroids - sedatives (2) - paralytics (Nimbex/cisatracurium besilate) (3)
Mucolytics (Liquefy secretions to help with their removal) Bronchodilators (beta 2 agonists and anticholinergics) - Relax smooth muscles when air flow limitations Steroids (Reduce airway inflammation) Sedatives - provide comfort - Decrease work of breathing and prevent ventilator fighting Neuromuscular paralysis (Nimbex-Cisatracurium besilate) - Decreases oxygen consumption: - sedate and explain all procedures to patient if giving paralytic b-c they do not inhibit pain or awareness - risk for immobility complications so prevent skin breakdown, DVT, and atelectasis
182
Noninvasive Ventilation: Advantages (4)
- Decreased VAP - Applied via mask (ex. CPAP, BiPAP) so easy application and removal - Increased comfort - Avoid danger of intubation while still keeping alveoli open
