Quanto Maior a Relação PaO2/FiO2 Melhor? #305 - SUNDAY PAPER | Ivens Giacomassi

Acute hypoxemic respiratory failure (ARF) is characterized by acute hypoxemia, currently defined as a ratio between the partial pressure of arterial oxygen (PaO2) and the fraction of inspired oxygen (FiO2) (PaO2:FiO2) less than 300, or a ratio between oxygen saturation and FiO2 less than 315. It can result from respiratory and non-respiratory diseases (cardiovascular or systemic diseases) and can occur in both intubated and non-intubated patients. The global burden is substantial, with approximately 1 million patients diagnosed with ARF each year. Acute hypoxemic respiratory failure is associated with high rates of acute hospitalization, intensive care unit (ICU) admission, mortality, and morbidity, including physical, psychological, cognitive, and functional morbidity.
