What does oxygen increase?
How does oxygen effect WOB
Oxygen corrects Hypoxemia and decreases what?
What are some hazards of O2
o2 induced hypoventilation
Indications for O2
severe acute myocardial infarction
short term therapy
To qualify as a high-flow device, a system should provide at least
60 L/min total flow
T/F High flow always exceeds the patients flow and provides fixed fio2.
Low flow does not exceed the patients flow, variable fio2, because ?
it becomes diluted with air
How many liters for low flow
8lpm or less
Nasal Canuula - humidifier is used only when the input flow is greater than
Nasal cannula is best indicated for.
Best used Patient in stable condition who needs low FiO2; home care patient who needs long-term therapy, low to moderate FiO2 while eating.
How do you calculate FIO2 for nasal cannula
22% at 1lpm, add 4% with every liter.
Nasal Cannula FIO2
Simple mask is indications
Emergencies; short-term therapy requiring moderate FiO2; mouth breathing patients requiring moderate FiO2
How many lpm for a simple mask?
Simple mask FIO2
Partial rebreathing mask
Emergencies; short-term therapy requiring moderate to high FiO2
Partial rebreathing mask FIO2
High flow AEM FIO2
High flow AEM indication
Patients in unstable condition who need precise low FiO2
