Ventilation

Question 1

NIV (non-invasive ventilation)

Answer 1

-Delivery of oxygen through face mask
-Improves gas exchange
-Treatment for resp failure
-Creates positive airway pressure, causing air to be forced into lungs which reduces work of breathing

Question 2

Constant Positive Airway Pressure
(CPAP)

Answer 2

-Provides constant fixed pos pressure throughout inspiration and expiration causing airways to remain open and reduce work off breathing
-Type 1 resp failure
-Hypoxemia

Question 3

Bi-level positive airway pressure (BIPAP)

Answer 3

-Provides differing airway pressures depending on inspiration & expiration
-Type 2 resp failure
