WebPO2 Art: 714180-00C Rev. Date: 09/29/03 Clinical Significance PO2 (partial pressure of oxygen) is a measurement of the tension or pressure of oxygen dissolved in blood. Some causes for decreased values of PO2 include decreased pulmonary ventilation (e.g. airway obstruction or trauma to the brain), impaired gas exchange between alveolar air and … WebMar 10, 2016 · The normal range for PaO2 is between 80 – 100 mmHg The Oxy-Haemoglobin Dissociate Curve As cells use up the floating oxygen, the PaO2 begins to fall. To maintain an equilibrium, the haemoglobin unloads more oxygen (dissociates) to float in the bloodstream ready to be used by the cells. WebThis is the main difference between PAO2 and SAO2. The normal PAO 2 of a healthy person should lie above 17 kPa or 128 mmHg which will result in a 100% SAO 2 whereas the normal SAO 2 is greater than 90%. Deviations of these levels act as markers and are important in analyzing the abnormalities in hemoglobins and Carbon monoxide poisoning. ... cognitive overload children

"WebDec 21, 2024 · 75-100 mmHg: Normal arterial oxygen pressure (PaO2) is approximately 75 to 100 millimeters of mercury (75-100 mmHg). Below 75 mmHg: When the levels drop below 75 mmHg, the condition is called hypoxemia. Below 60 mmHg: Levels below 60 mmHg are considered very low and indicate the need for supplemental oxygen.
