Reasons for low pao2

Webb26 sep. 2014 · A low PaO2/FiO2 value has been associated with increased mortality and hospital stay in patients admitted to the intensive care unit (ICU) [ 5 – 8 ]. The PaO2/FiO2 ratio is widely used in ICUs because it quickly and easily provides data on the oxygenation status of critically ill patients. Its values are included in ICU prognostic scores [ 9, 10 ]. Webb22 mars 2024 · Patients with a PaO2 between 7.3 kPa and 8 kPa (55 mmHg and 60 mmHg) and secondary polycythaemia, peripheral oedema, evidence of pulmonary hypertension or nocturnal hypoxaemia (defined as oxygen saturation (SaO2) below 90% for at least 30% of the night [5]), are specifically recommended for LTOT [3].
