COVID-19 & O2 Delivery/Ventilation (Ko)
what is oxygenation? - correct answer process of adding oxygen to body
-provides O2 assistance
what is ventilation? - correct answer movement of air into and out of the lungs
-helps w gas exchange
list 4 methods of O2 delivery that provides oxygenation assistance - correct answer nasal cannula
(NC)
mask or oxymask
nonrebreather (NRB)
high-flow nasal cannula (HFNC)
which non-invasive ventilation method provides oxygenation & ventilation (gas exchange)? -
correct answer BiPAP (Bilevel Positive Airway Pressure) -> most common
-a mask, pt is not intubated
which invasive ventilation methods provides oxygenation & ventilation (gas exchange)? - correct
answer via:
-endotracheal tube (intubation)
-tracheostomy (a surgical airway) -put directly into trachea
high-flow nasal cannula (HFNC) % O2 delivered (FiO2), reason to use, supports pt's ________ -
correct answer 100% (full oxygenation)
-can deliver high FiO2, is more comfortable vs mask longer-term
-used often for COVID-19
-supports pt's oxygenation
BiPAP (Bilevel Positive Airway Pressure) % FiO2, reason to use, drawbacks, supports pt's ______
- correct answer start at 100% -> titrate down to 40%
-delivers O2 but also assists ventilation by forcefully pushing air into airways, opening alveoli to
inc gas exchange
-forceful pressure into airway is not comfortable, high aspiration risk!
-supports pt's oxygenation & ventilation
what is aspiration? - correct answer inhaling fluid (secretions or when drinking) into lungs
-irritates lungs -> can develop pneumonia
what are 2 common clinical scenarios that use BiPAP? - correct answer 1. acute decompensated
HF w/ pulm edema (commonly seen)
