A P/F ratio of 225 is equivalent to a pO2 of 45 mmHg, which is significantly < 60 mmHg on room air. How to Calculate FIO2 from Liters A nasal cannula provides oxygen at adjustable flow rates in liters of oxygen per minute (L/min or “LPM”). The actual FIO2(percent oxygen) deli...
The use of heated and humidified high flow nasal cannula (HFNC) has become increasingly popular in the treatment of patients with acute respiratory failure through all age groups. In this part we will summarize how it works and for part 2 we will discus
