Fraction of inspired oxygen (FIO2), corrected denoted with a capital "I", is the molar or volumetric fraction of oxygen in the inhaled gas. Medical patients experiencing difficulty breathing are provided with oxygen-enriched air, which means a higher-than-atmospheric FIO2. Natural air includes 21% oxygen, which … Ver mais Abbreviated alveolar air equation PAO2, PEO2, and PIO2 are the partial pressures of oxygen in alveolar, expired, and inspired gas, respectively, and VD/Vt is the ratio of physiologic dead space over tidal volume. Ver mais Alveolar air equation The alveolar air equation is the following formula, used to calculate the partial pressure of alveolar gas: Ver mais • FiO2 by Delivery Device Archived 2015-09-20 at the Wayback Machine - Shows FiO2 by common oxygen deliver systems. Ver mais In medicine, the FIO2 is the assumed percentage of oxygen concentration participating in gas exchange in the alveoli. Ver mais The FIO2 is used in the APACHE II (Acute Physiology and Chronic Health Evaluation II) severity of disease classification system for intensive care unit patients.
