FIO2=（21+20x(Rate of Oxygen Flow in liters per minute)）÷100这种方法是用于估计通过氧气流量调节吸入氧气浓度的情况。通常使用氧气抢救或其他治疗，使氧气流量从1升/分钟增加到15升/分钟，FIO2可以从21％增加到低至45％左右。需要指出的是，这些公式只是针对一些特定情况下估算FIO2的方式，并不能...

The mask assembly delivers 100% or less than 100% oxygen to the alveolus while using significantly lower flow rate than conventional masks.doi:US20040060560 A1Alex StenzlerJoseph A. FisherAlex VeselyHiroshi SasanoRon B. SomogyiGeorge Volgyesi
For patients on non-rebreather mask, F iO2 was estimated using a 3%-for- mula (21% + oxygen flow rate in L/min × 3) [22, 23], that was found to have the best agreement and highest accu- racy when compared with measured FiO2 [24]. Patients breathing on CPAP or...
Continuous on-line breath-by-breath measurement of pulmonary gas exchange was used to monitor the increase in oxygen uptake (Vo2) and carbon dioxide excretion (Vco2) induced by the oxidative phosphorylation uncoupling agent 2, 4-dinitrophenol (DNP) in 10 dogs. With incremental doses of DNP tot...
Using a multivariate logistic regression model, we identified four markers associated with the impending use of MV, including the ratio of peripheral blood oxygen saturation to fraction of inspired oxygen (SpO2/ FiO2 ratio), alanine aminotransferase, blood glucose (BG), and lymphocyte counts. ...
Venturi-based flow generators are commonly used for noninvasive continuous positive airway pressure (CPAP) of high-flow nasal oxygen (HFNO). The system is simple and allows to increase the total flow while decreasing the FiO2 starting from a single oxygen source. In this report we describe the...

The FiO2 delivered with standard facemask was calculated as 0.4 with 5–6 l of oxygen, 0.5 with 6–7 l and 0.6 with >7 l of oxygen flow and with non rebreathing mask (NRBM) as 0.9 with 12–15 l of flow. The exact FiO2 was set on the high flow nasal cannula (HFNC) machine ...
