What is the purpose of Positive Airway Pressure (PAP)?
|
To deliver a continuous flow of air that increases pressure in the upper airway and prevent airway collapse
|
|
What are the three types of PAP?
|
Continuous Pressure (CPAP)
Bilevel PAP (BPAP) Auto-Titrating (APAP) |
|
What are the benefits of PAP?
|
1) Immediately effective, relatively non-invasive
2) Reduce complaints 3) Modifies consequences of OSA |
|
What main problems are associate with PAP?
|
1) Mask discomfort
2) Patient acceptance (of lack of) 3) Aerophagia 4) Chest Discomfort |
|
What is aerophagia?
|
the swallowing of air
|
|
What does PAP selection depend on?
|
1) Shape of face
2) Facial Hair 3) Patient ability to breathe through nose 4) patient preference |
|
What are solutions for dryness due to PAP?
|
1) Humidification
2) Prevent Leaks |
|
What are solution to claustrophobia due to PAP?
|
1) Less cumbersome interface
2) Desensitization |
|
What are solution to aerophagia due to PAP?
|
1) Body positioning
2) Reduce mean airway pressure |
|
What are solutions for rhinitis and nasal congestion?
|
1) Humidification
2) Nasal steroids or decongestants |
|
What is a solution to air leaks?
|
Proper mask and headgear

|
|
How often, by how much, and until when should CPAP pressure be increased?
|
Every 5 minutes, by at least 1 cm till obstructive events are eliminated.
|
|
For a child, when should CPAP titration be increased?
|
After 1 obs apnea
After 1 obs hypopnea After 3 RERAs or 1 minutes of loud unambiguous snoring |
|
For an adult, when should CPAP titration be increased?
|
After 2 obs apneas
3 obs hypopneas 5 RERAs or 3 minutes of loud unambiguous snoring |
|

AHI greater than or equal to 40 for 2 hours of PSG
|
|
How long should CPAP titration be carried out during a Split Night Protocol?
|
3 hours
|
|
When is bilevel PAP (BPAP) used?
|
1) When a high level of pressure is needed and the pt has trouble with fixed pressure
2) Hypoventilation is present |
|
What is BPAP useful for treating?
|
1) Restrictive lung disease
2) Hypoventilation syndrome associated with daytime hypercapnia |
|
What is IPAP?
|

|
set lowest to prevent airway collapse during expiration
|
|
What is the goal of IPAP?

APAP increases CPAP to eliminate airway obstruction then lowers overnight to keep CPAP at lowest possible level
|
|
