Introduction To Treatment Flashcards
(31 cards)
Aiming to treat
Sputum retention
Reduced lung volume
Increased work of breathing
Pain
Fatigue
Reduced exercise tolerance
Hypoxia and respiratory failure - can be caused by several problems, can be life-threatening
Oxygen therapy
Is a drug
Should be prescribed with target sats
Except in an emergency situation when someone is critically unwell - when a patient is critically unwell or has SpO2 < 85%, once stable, aim for SpO2 94-98% or patient-specific target range
Oxygen therapy: target saturations
94-98% for most (scale 1)
88-92% for patients at risk of CO2 retention (scale 2)
92-96% for Covid positive patients
Oxygen therapy: oxygen delivery
Nasal specs/ cannulae - up to 6L but generally 4L
Face mask - high flows, 10L
Resivour mask - 15L
Humidified system - oxygen with moisture in it, can be more comfortable than dry oxygen, good if the patient has mucus retention, 60% oxygen
Venturi system - different coloured valves for different percentage of oxygen, 15L
Trachemasks - accommodate the tracheostomy, normally humidified
Oxygen therapy: titrating up and down
Increased FiO2 if SpO2 is lower than target range
Decrease FiO2 if SpO2 is higher than target range
Monitor SpO2 for 5 minutes at every change
If FiO2 is increased, medical assessment is needed
Ensure any changes are documented
Oxygen therapy: to much oxygen
Absorption atelectasis - absorption of oxygen from alveoli exceeds replenishment of alveolar gas, so that the alveoli are no longer held open by a cushion of inert nitrogen
High concentrations may impair the respiratory drive of hypercapnia COPD patients
Excess oxygen depletes protective anti-oxidants, causing oxygen toxicity - inflammatory response of lung tissue, predominantly
Effect the CV system - increase systemic vascular resistance
Oxygen therapy: nebulisers
Direct delivery of medication to the lungs
Saline (0.9% or 7%) - can aid airway clearance by reducing the viscosity of sputum
Bronchodilators can reduce bronchoconstriction to aid air flow
Device that delivers smaller particles that can be inhaled by the lungs
Flow rate of 6-8L in order for the particles to be small enough to be breathed in
Oxygen therapy: other medications
Consider from drug history
Pain management - if in pain they will struggle to participate in what you want them to do
Timing of these can be important
Positioning
For postural drainage/ gravity assisted drainage
For V/Q matching
For work of breathing
Basic invention, and can be used with other treatments
Positioning: postural drainage
Uses gravity to assist drainage of secretions
Area to be drained position highest
Most affected area drained first
Ideally 10 minuted in each position
Maximum of 3 positions per session
A position for each lobe
Positioning: postural drainage precautions/ contraindications
When placing head down
Increased work of breathing
Head and neck pathology/ raised intercranial pressure
Cardiovascular pathology
Abdominal pathology
Pregnancy
Obesity
Care with attachments
Reflex GERD/ GORD or nausea
Positioning: V/Q matching
Repositioning patient to facilitate deep breathing and expansion
You can position the patient into side lying so the middle zone is in line with the larger airways so the sputum/ mucus is drained into them so they can be cleared
Positioning: to decrease work of breathing
Aims - stabilise shoulder girdle/ optimise thoracic cage movement, dome a flattened diaphragm, decrease energy consumption
Forward lean standing and sitting
Supported forward lean sitting
Supported high side lying
Active cycle of breathing technique (ACBT)
3 stages repeated as a cycle
1. Breathing control
2. Thoracic expansion exercises (TEEs)
3. Forced expiratory technique (FET)
Flexible approach and can be adapted without assistance
Patients with long term condition e.g. bronchiectasis, may be taught this as a self-management strategy for regular airway clearance
Active cycle of breathing technique (ACBT): breathing control
Tidal breathing
Encourage - relaxation of upper chest, diaphragmatic breathing; can allow the patient to control their breathing
Proprioceptive facilitation
Continue until patient is ready to progress
1. One hand on stomach and one hand on chest, breath in through nose
2. Feel stomach expand against your hand and your chest should barely move
3. Breathe out through your mouth and you’ll feel your stomach sink back down
Active cycle of breathing technique (ACBT): thoracic expansion exercises (TEEs)
Deep breathing exercises - 3 to 5 breaths normally
Encouraging lateral chest expansion - hands on ribs for proprioceptive feedback
Can add a 3 second hold and a ‘sniff’
Hold - decrease collapsed lung tissue and may be good for those with lung pathology as air will first fill the unobstructed area and then give time for ventilation of collateral pathways
Increased collateral ventilation
Monitor - patients can become lightheaded
Active cycle of breathing technique (ACBT): forced expiratory technique (FET)
Forcefully expelling air through an open throat and mouth
Huff - trying to fog up a mirror
Move sputum form small to larger airways
Medium to high volume
Not to many as it can cause bronchospasm
May initiate a cough
Normal breath in and long huff out - medium, moved from more peripheral airways
Deep breath in and short sharp huff out - high, moved from more central airways
Active cycle of breathing technique (ACBT): physiology of FET
Equal pressure point - point at which pressure inside the airway is equal to the pressure outside (intrapleural pressure)
Where in the airway this begins depends on where in the airway the pressure is equal to that outside the airway aka a the EPP
The EPP depends in the volume of inspired air
Active cycle of breathing technique (ACBT): adapt the treatment to the patient
Breathing control - can reduce work of breathing
Thoracic expansion exercises - hold and sniff can help improve lung volume
Forced expiratory technique - high and low volumes to aid sputum clearance, can also be taught prophylactically
Add in more or less of each component to meet the needs of the patient
Active cycle of breathing technique (ACBT): precautions
Consider whether the patient can follow instructions
Bronchospasm - care with FET, may have or need bronchodilators prior to maximise effects
Consider the numbers of TEE and effect on blood pressure
Manual techniques: percussion
Rhythmical patting of the chest with a cupped hand; creates a cushion of air
Perform during normal tidal breathing
Loosens the sputum from the walls of the airways
Use a towel
Side lying
Manual techniques: shakes
Application of large oscillatory movements to the chest wall
Usually performed on expiration
Mobilise secretions along the airways
Push in and out not up and down
Manual techniques: vibrations
Fine oscillatory movements to the chest wall
Usually performed on expiration
Mobilise secretions along the airways
Manual techniques: precautions
Bronchospasm
Pain
Osteoporosis
Bone metastases
Near chest drains
