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...

Results. – Protocol 1 (without visual control of the pressure): increase in oxygen flow delivered with the Ambu® increases the FiO2 values (P < 0.0001); the higher the ventilatory frequency, the lower the FiO2 (P < 0.0001). The mean value of delivered FiO2 was related to the operator...

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. ...
