Techniques for maintaining an airway that are not artificial airway?
Hydration, positioning, nutrition, chest PT techniques, suctioning, deep breathing, coughing, humidity, incentive spirometry, and noninvasive techniques help in maintaining an airway
• Artificial airway is needed when these do not clear secretions
What might be done before suctioning to limit hypoxia induced by this procedure?
• Preoxygenation and deep breathing sometimes referred to as hyperventilation, help to reduce suction-induced hypoxemia.
If mech vent, preoxygenation done by inc % of inspired oxygen breaths delivered by a mechanical ventilator
Hyperinflation is
the process of providing 100% oxygenation ot a patient before airway suctioning
T/F
all pt need preoxygenation before suctioning
F - not all - not needed unless hypoxemic
What to do after suctioning with O2 levels?
o Following suctioning, return a pt o2 level to presuctioning levels to avoid inc risk for o2 toxicity.
It is normal to do normal saline instillation (NSI) into artificial airways these days?
• Practice of normal saline instillation (NSI) into artificial airways is no longer recommended as standard practice. was thought to remove secretions
o Suctioning with ot without isotonic normal saline produces similar amounts of secretions and significant dec in o2 sat.
What sort of things are you assessing for prior to scuitoning? (including medical hx)
- Risk factors for upper or lower aiway obstr (COPD, infections, impaired mobility, sedation, dec LOC, seizures, presence of feeding tubes, dec gag or cough reflex, dec swallowing)
- SIgns of hypoxemia/hypercapnia
- Vitals
- S&S of upper and lower a/w obstr requiring airway suctioning, including qhezing, crackles, or gurgling on inspiration or expiration, restlessness, ineffective coughing, diminished breath sounds, tachypnea, HTN, hoTN, cyanosis, dec sec, drooling or gastric secretions
- Assess for additional factors that anatomically influence upper or lower airway function (surgery, tumors) …it impairs normal drainage of secretions and can impair or occlude airway
- Assess factors that affect vol and consistency of secretions
a) fluid balance- fluid overload inc secretions
b) lack of humidity- dehydration promotes thicker secretions
c) infection- - Examine sputum microbio data
- Assess pt understanding of procedure
Why is head injury a risk when suctioning?
- Use caution when suctioning pt with head injury. Inc iCP. Reduce this risk by presuctioning hyperventilation, which results in hypocarbia. This in turn induces vasoconstriction, thereby reducing risk of ICP
What sort of meds would need to be assessed prior to suctioning?
- Know SE of meds. Some meds such as beta-adrenergic blockers have side effect of bronchospasm. Resp depression for opiods. Too much o2 reduces drive to breath w pt w chronic hypercapnia
Difference between oropharyngeal + tracheal suctioning?
- Major differences between oropharyngeal and tracheal airway suctioning are the depth suctioned, the potential for complications and the need for it to be a sterile procedure
- Oropharyngeal- removes secretions from back of throat
- Tracheal airway suctioning extends into the lower airway- indicated to remove resp secretions and maintain optimum ventilation and oxygenation in pt who are unable to remove secretions on own
Under what level of O2 is a good indicator that suctioning is needed?
When o2 is below 90% good indicator they need suction
Complications/problems with suctioning/
- What is not suctioned can move into lungs- aspiration, infection,
- Tracheal suctioning risks: hypoxemia often leading to cardiac dysrhythmias, laryngreal spasm or bradycardia (associated w stimulation of vagus nerve)
- Nasal trauma and bleeding can develop from trauma from suction catheter
Endotracheal tubes + trachs protect the airway from gross aspiration in patients with…
impaired cough or gag reflexes.
Special consideration for metal trachs r/t safety?
• Metal TT are thermal sensitive and must be protected from extreme heat and cold to prevent tissue injury to the patient.
When is a closed system suction catheter used?
• Some use closed suction catheter system or in-klaw suction catheter device to minimize infections, especially in critically ill or immunosuppressed pts
• Use of a closed system catheter allows quickler lower airway suctioning without applying sterile gloves or a mask and oes not interrupt ventilation and oxygenation in critically ill patients.
o With a closed system the patients artificial airway is not disconnected from mechanical ventilation
S+S of hypercapnia/hypoxemia
presence of apprehension, dec ability to concentrate, dec LOC, inc fatigue, dizziness, behaviour changes, pallor, cyanosis, dyspnea or use of accessory muscles (can indicate hypoxia, hypoxemia, or hypercapnia)
First 3 steps for initiating suctioning?
- ID, HH, goggles or face shield if splashing, mask
- Connect suction and have end close to patient in convenient location. Set suction pressure s low as possible.
- Prepare suction catheter
How to prepare one time use catheter?
a) use aspetic twchnique, open suction kit or catherer. If sterile drape is available, place acorss patients chest or on over-bed table. Do not allow suction catheter to touch any nonsterile surfaces
b) unwrap or open sterile basi and place on bedside table. Be careful not to touoch inside of basil. Fill with 100ml of sterile water
c) open lubricant, squeeze small amount onto open catheter package (no neeed for artificial airway suctioning)
- Apply sterile gloves or nonsterile to nondominant and sterile to dominanant
- Pick up suction with dominant hand and pick up connecting tubing with nondominant hand
How do you hyperoxygenate a pt prior to suctioning?
Hyperozygenate pt with 100% o2 for 30-60 sec before suctioning by adjusting inspired o2 setting on mechanical ventilator or using an oxygen-enrichment program on microprocessor ventilators.
How do you insert the catheter for suctioning?
With or without suction on?
Without applying suction, gently but quickly insert catheter into artificial airway using dominant thumb and foreginger until you meet resistance or pt cough then pull back 1cm.
Why do you apply suction AFTEr putting catheter in?
- application of suction pressure without introducing catheter into trachea inc risk for damage to tracheal mucosa and inc hypoxia.
Why do you pull back after meeting resistance?
Pulling back stimulates cough and removes catheter from mucosal wall so catheter is no resting on it
How do you apply suction?
What do you want to encourage pt to do while suctioning?
- Apply continuous suction by placing nondom thumb over vent of catheter, slowly withdraw catheter while rotating it back ad forth between dom thumb and forefinger.
Encourage pt to cough. Watch for resp distresss
Do you want intermittent or continuous suction?
Use continuous suction
