Oxygen Therapy Flashcards
Oxygen Delivery Systems
used to administer, regulate, and supplement oxygen
Nasal cannula
low-flow device used for non-acute situations
-two prongs (one for each nostril, pointing down)
-loops behind the ears, not the head!
-can be ordered as humidified to decrease nasal irritation/dryness
Simple mask
low-flow device used for non-acute situations
-air holes on both sides allow for some external air exchange
-fits to the face with a strap around the head
Non-rebreather mask
low flow decide used for acutely ill pts
-one way valves prevent outside air from entering
-reservoir bags holds oxygen as a reservoir source for the patient as they breathe
High-flow oxygen therapy
high-flow device, often a high-flow nasal cannula
-similar setup to nasal cannula, but with high flow oxygen
-can be ordered as humidified to decrease nasal irritation/dryness
Venturi mask
high flow device: best for patients with chronic lung disease
-most precise O2 delivery without intubation (controlled percentages of O2)
Face tent
effective for those who don’t tolerate masks well
-good for pts with facial trauma or burns, or pts who will not tolerate a fitted mask
-provides humidification
