positive pressue ventilation is usually provided by a mechanical ventilator. A blend of oxygen and air coming out of the ventilator. The FiO2 is set on the ventilator. The person gets the FiO2 set on the ventilator.The manual positive pressure ventilation is by resuscitating with a self inflating bag usually provided with oxygen. FiO2 is fractional inspired oxygen and does not change with positive pressure ventilation or negative pressure ventilation. Manual bagging FiO2 may be changing according to supply of oxygen, inhalation (speed and volume) and frequency of bagging.
PAO2 - PaO2 ****************************************** PAO2 is the Alveolar Air Equation: PAO2 = FiO2 (Pb- Ph20) - PACO2/R Notes: Pb = 760 mmHg Ph20 = 47 mmHg R = 0.8

Oxygen
Typically, the air you breathe is comprised of 18 to 21 percent Oxygen.
This is the percent of oxygen a patient is inhaling. Room air FiO2 is 21%. By applying supplemental oxygen, the FiO2 can go as high as 100%.
Each litre is equivelant to approximately 3%. 35% Oxygen is about 5 litresThis math here is only correct if you are using a nasal cannula to deliver the oxygen. Respiratory therapy only uses this as an estimate since the cannula isn't the most effective oxygen delivery system but is the most comfortable for a patient.21% Fio2 is room Air, that is we breath in normally, for anyone without any supplemental Oxygen.The first 1 liter is 3%Fio2, which is 21% +3% =24%Fio2, thereafter it is 4% to each liter flow of oxygenFirst liter of Oxygen which is 1Lpm =3% + 21%(Room Air) Total = 24% Fio2 Add 4% for each liter flow there 2Lpm= 28% Fio23Lpm= 32% Fio2Save4Lpm= 36% Fio25Lpm= 40% Fio26Lpm= 44% Fio2For a Venturi Mask which is more effective especially for patients with COPD the Fio2 settings are as follows:White cap:35% FiO2 set lpm at 940% FiO2 set lpm at 1250% FiO2 set lpm at 15Green cap:24% FiO2 set lpm at 3lpm26% FiO2 set lpm at 3lpm28% FiO2 set lpm at 6lpm30% FiO2 set lpm at 6 lpm
To convert FiO2 from liters to a percentage: Determine the liters of oxygen being administered. Divide the liters of oxygen by 5 to get the approximate FiO2 percentage. For example, if 2 liters of oxygen is being administered, the FiO2 can be estimated at around 40% (2/5 = 0.4 or 40%). Keep in mind that this is an approximation and actual FiO2 may vary depending on the oxygen delivery system used.
FiO2 stands for Fraction of Inspired Oxygen, which represents the percentage of oxygen in the air that is being inhaled. It is commonly used in medical settings to monitor and adjust oxygen therapy for patients.
Yes, the flow rate of oxygen delivered through a venturi mask can affect the fractional inspired oxygen concentration (FiO2) that the patient receives. Higher flow rates can increase the FiO2 by providing more oxygen to mix with room air as it flows through the mask's entrainment ports.

Although "breatharians" claim that they can live without eating by just breathing fresh air, there is no nutrition value to air.

21%
air is made of 19.98 percent oxygen 79 percent nitrogen and 2 percent carbon
20 Percent.
The percent of oxygen in dry air is approximately 21%.
