Correlation of Oxygen Index, Oxygen Saturation Index, and PaO2/FiO2 Ratio in Invasive Mechanically Ventilated Adults.doi:10.5005/jp-journals-10071-23506Sonali VadiIndian Society of Critical Care Medicine
Pulse oximetry is a standart of anesthesia for perioperative monitoring. Due to the principles of Hb oxygen dissociation curve, peripheral oxygen saturation has an approximate sensitivity and specificity of 90% for the detection of hypoxemia. The primary
Figure 5-1. Oxygen pressure, saturation and content.Schematic shows cross section of lungs and pulmonary circulation. (CO2, nitrogen and other gas molecules are omitted for clarity.) PaO2is always slightly lower than PAO2because of normal venous admixture, here represented by a connection between t...
Hypoxia ranges typically refer to the levels of oxygen in the blood, which are measured using parameters such as partial pressure of oxygen (PaO2) or oxygen saturation (SpO2). Based on the severity of oxygen deprivation in the blood, hypoxia can be classified into these ranges: mild, moderate...
Patients were required to have persistent hypercapnia (Paco2 >53 mm Hg) and hypoxemia (Pao2 <55 mm Hg or <60 mm Hg; ≥1 of polycythemia, pulmonary hypertension, or cor pulmonale; >30% of sleep time with oxygen saturation <90% as measured by pulse oximetry); and arterial pH greater ...

The median Pao2 was 11.3 kPa (9.8–13.6 kPa), Fio2 was 0.40 (0.35–0.50), and arterial oxygen saturation (Sao2) was 97% (95–99%). Distributions of sampled ABGs, including overall Pao2 and Fio2 values, and median person-specific Pao2 and Fio2 levels are presented in Fig 2. Overview ...
Fio2 indicates fraction of inspired oxygen; Paco2, partial pressure of arterial carbon dioxide; Pao2, partial pressure of arterial oxygen; PEEP, positive end-expiratory pressure; PSV, pressure support ventilation; and Spo2, peripheral oxygen saturation as measured by pulse oximetry. Figure 2. ...
