What is normal PaO2 level?

Normal Results Partial pressure of oxygen (PaO2): 75 to 100 millimeters of mercury (mm Hg), or 10.5 to 13.5 kilopascal (kPa) Partial pressure of carbon dioxide (PaCO2): 38 to 42 mm Hg (5.1 to 5.6 kPa) Arterial blood pH: 7.38 to 7.42.

How do you interpret PaO2?

PaO2 is directly measured by a Clark electrode and can be used to assess oxygen exchange through a few relationships.

  1. Normal PaO2 values = 80-100 mmHg.
  2. Estimated normal PaO2 = 100 mmHg – (0.3) age in years.
  3. Hypoxemia is PaO2 < 50 mmHg.

What is a normal PO2 on an ABG?

ABG (Arterial Blood Gas)

pH 7.31–7.41
pCO2 41–51 torr 5.5–6.8 kPa
pO2 30–40 torr 4.0–5.3 kPa
CO2 23–30 mmol/L
Base excess/deficit ± 3 mEq/L ± 2 mmol/L

What is PaO2 in ABG?

An arterial blood gases (ABG) test measures the acidity (pH) and the levels of oxygen and carbon dioxide in the blood from an artery. Partial pressure of oxygen (PaO2). This measures the pressure of oxygen dissolved in the blood and how well oxygen is able to move from the airspace of the lungs into the blood.

What is pa02 normal range?

Most healthy adults have a PaO2 within the normal range of 80–100 mmHg. If a PaO2 level is lower than 80 mmHg, it means that a person is not getting enough oxygen .

What would PO2 be on 100 oxygen?

approximately 100 mm Hg
For example, at sea level with no additional supplemental oxygen and a normal physiological state, the PO2 inside the alveoli calculates at approximately 100 mm Hg. But, if a patient is given 100% oxygen in the same situation the PO2 can be as high as 663 mm Hg.

What should PaO2 be on 100 oxygen?

What is a normal SaO2?

What is a safe oxygen saturation level? Oxygen saturation levels (SaO2) ranging between 95% and 100% are considered normal. SaO2 levels lower than 90% (hypoxemia) may lead to health complications and if it drops below 70%, the outcome may be fatal.

Are pO2 and PaO2 the same?

PO2 , SaO2 , CaO2 are all related but different. If the lungs are normal, then PaO2 is affected only by the alveolar PO2 (PAO2), which is determined by the fraction of inspired oxygen, the barometric pressure and the PaCO2 (i.e., the alveolar gas equation).

What is the normal pa02?

What is PaO2 and PaO2?

With PAO2 representing alveolar oxygen pressure and PaO2 representing arterial oxygen pressure. The arterial oxygen pressure (PaO2) can be directly assessed with an arterial blood gas test (ABG) or estimated with a venous blood gas test (VBG).

What should pa02 be?

When the body is functioning normally, PaO2 is between 75 and 100 mmHg (at sea level). 5 A result in this range means a sufficient amount of oxygen flowing from the alveoli to the blood.
