CPAP Flashcards
(11 cards)
What is CPAP used to treat?
Obstructive sleep apnea and respiratory failure
CPAP stands for Continuous Positive Airway Pressure.
How is CPAP therapy for respiratory failure typically delivered?
Through a mask secured to the face by some type of strap.
What happens when the CPAP bag is squeezed more forcefully?
The higher the pressure.
What can high CPAP pressure lead to?
- Evolution of simple pneumothorax into tension pneumothorax
- Huge amounts of subcutaneous air
- Impeded or blocked venous return
How can excessive CPAP pressure affect a patient with low blood pressure?
It can reduce venous return to the heart, causing a sudden drop in blood pressure.
What is important to ensure when using a CPAP mask?
A good seal with minimal leakage.
What feature does the CPAP mask have to control pressure?
A pressure-relief valve that determines the amount of pressure delivered.
What is an example of a pressure setting for CPAP?
5 cm H2O.
What should you avoid doing with a patient unwilling to use the CPAP mask?
Struggling with the patient.
What indicates that CPAP therapy is likely to succeed shortly after application?
Increase in oxygen saturation and decline in respiratory rate.
What indicates that CPAP therapy is likely to fail shortly after application?
Increase in respiratory rate.
