BVM, NONrebreather, Nasal Cannula Flashcards
when to use, differences between
What is a Nonrebreather Mask?
A mask with a one-way valve that allows for high-flow oxygen delivery
When would you use a Nonrebreather?
In patients with severe hypoxia or respiratory distress: where high oxygen levels are needed (10-15 L/Min)
what are the advantages of using a Nonrebreather?
it provides high concentration (up to 90%) ideal for patients who are alert but severely hypoxic; shock, respiratory failure, severe trauma
when should you not use a nonrebreather on a patient?
they are unconscious, have facial trauma, and cannot maintain their own airway
What is an NPA and when is it used?
a small tube that delivers oxygen through the nostrils; used for mild hypoxia, who need low flow oxygen and can breathe on their own
What is the oxygen flow rate for a Nasal Cannula?
1-6 L/M; delivers oxygen concentrations between 24% and 44%
What are the advantages of using Nasal Cannula?
allows the patient to speak, eat, move around while receiving oxygen. ideal for patients with mild respiratory distress and chronic conditions.
What is a BVM and when is it used?
A device to provide positive pressure ventilation to those who are not breathing or breathing inadequately; unresponsive patients who needs assistance with ventilation
what is the oxygen flow rate of a BVM? and how much oxygen does it provide %
flow rate is 15 L/M or higher when attached to an oxygen source. delivers nearly 100% oxygen to patient
what is the difference between BVM and Nonrebreather?
A BVM is used for patients who are not breathing and unresponsive and NRB is used for patient who are breathing but require high flow oxygen
When would you use a Nasal Cannula over a Nonrebreather Mask?
Nasal canula is used for patients who require low flow oxygen whereas NRB is used for more acute and severe
