Rehab For Restrictive Lung Dz Flashcards
Most effective method of mechanical assistance for secretion clearance in paralyzed patients
Mechanical insufflator exsufflator
Examples of intermittent abdominal pressure ventilators (IAPV)
Pneumobelt and exsufflation belt
Potassium levels and respiratory sufficiency
Hypokalemia can exacerbate respiratory muscle insufficiency
What patients do you not want to use IAPV in?
Patients with decreased pulmonary compliance and or with increased airway resistance
Breathing technique using pistoning action of tongue to project boluses of air into lung if there is ventilator equipment failure
Glossopharyngeal breathing
3 types of negative pressure ventilators
Tank ventilators, wrap ventilators, cuirass ventilators
What is a hayek oscillator?
Negative and positive pressure body ventilator with a suit that changes in pressure to help with chest compression and expiration
Only negative pressure body ventilators that can be used during the day while seated
Cuirass ventilators
How does IAPV work?
It pushes abdominal contents during expiration to help force expiration, and then passive inspiration
Contraindications for negative pressure ventilators
Upper airway obstruction
How does oxygen treatment in COPD patients lead to respiratory failure
Inhibition of hypoxic pulmonary vasoconstriction, leading to worsening v/q mismatch –> hypercapnia –> resp failure
2 types of negative- and positive-pressure body ventilators
Rocking bed and external oscillation ventilator (Hayek oscillatory)
What does a rocking bed do?
Rocks back and forth along a vertical axis, raising and lowering the patient’s head, using gravity to help with diaphragm move and help with breathing
Major cause of respiratory failure in patients with restrictive lung disease is _________
Impaired secretion clearance
