To evaluate partial pressure of oxygen in arterial blood/fractional percentage of inspired oxygen (PaO2 /FiO2 ) and SaO2 /FiO2 ratios (where SaO2 is percentage of oxyhemoglobin saturation in arterial ...
Arterial blood gases (PaO2, SaO2) and pulse oximetery (SpO2) are helpful in determining the need for oxygen therapy. Although hypoxia is defined as PaO2 < 60 mmHg and SaO2 (SpO2) < 90%, oxygen should ...
