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
Embodiments provide an oxygen supply device comprising an oxygen production unit, a control unit, an air blower and a gas conditioning unit. The oxygen production unit comprises mul
However, although higher PaO2 levels may improve the oxygen delivery, they can also lead to potential harm such as the tissue injury. To correct the effect of FiO2 on the PaO2, the ratio of arterial partial pressure of oxygen (PaO2) to fraction of inspired oxygen (FiO2) is usually used. ...
(WHO score 1–2) that correspond to the presence of mild symptoms, “moderate” for patients who no required supplemental oxygen (WHO scores 3–4), and “severe” for all patients who needed oxygen support (WHO scores 5–8 high-flow oxygen requirement continuous positive airway pressure (...
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 ...

Introduction: The use of steroid therapy in patients within the context of SARS-CoV-2 infection is still a matter of debate. This study aimed to evaluate if potential steroid benefits could be predicted by the ratio of arterial oxygen partial pressure (P
To maintain adequate oxygenation is of utmost importance in intraoperative care. However, clinical evidence supporting specific oxygen levels in distinct surgical settings is lacking. This study aimed to compare the effects of 30% and 80% oxygen in off-p
