Arterial Blood Gas (ABG): What It Is, Purpose, Procedure & Levels
In general, normal values at sea level include: pH: 7.35-7.45. Partial pressure of oxygen (PaO2): 75 to 100 millimeters of mercury (mmHg). Partial pressure of carbon dioxide (PaCO2): 35 to 45 mmHg. Bicarbonate (HCO3): 22 to 26 milliequivalents per liter (mEq/L). Oxygen saturation (O2Sat or SaO2): 95 to 100%.

2024年1月8日 · A normal PaO 2 value does not rule out respiratory failure, particularly in the presence of supplemental oxygen. The PaCO 2 reflects pulmonary ventilation and cellular CO 2 production.
Arterial Blood Gas (ABG) Analysis | Values & Interpretation
2024年8月23日 · ABG Normal Values. The aforementioned components all have different normal values and represent different aspects of the blood gas. According to the National Institute of Health, typical normal values are: pH: 7.35-7.45; Partial pressure of oxygen (PaO2): 75 to 100 mmHg; Partial pressure of carbon dioxide (PaCO2): 35-45 mmHg; Bicarbonate (HCO3 ...
What Are Blood Oxygen Levels by Age? Chart, Normal, High
2022年12月21日 · Normal arterial oxygen pressure (PaO2) measured using the arterial blood gas (ABG) test is approximately 75 to 100 millimeters of mercury. Understand levels, chart, and hypoxemia. Health A-Z
ABG Interpretation Made Easy: Arterial Blood Gases (2024)
2024年9月11日 · PaO2: Lower than 60 mmHg indicates hypoxia and potential respiratory failure. PaCO2: Higher than 50 mmHg suggests hypercapnia and may indicate respiratory failure, especially if accompanied by a low or declining pH.
Partial Pressure of Oxygen (PaO2) Test: Uses and More
2023年7月17日 · When the body is functioning normally, PaO2 is between 75 and 100 mmHg (at sea level). A result in this range means a sufficient amount of oxygen is flowing from the alveoli to the blood. If your PaO2 is below the normal range, that is not the case.
Partial Pressure Of Oxygen - StatPearls - NCBI Bookshelf
2022年12月22日 · PCO 2 is the partial pressure of carbon dioxide in the arteries, about 40 to 45 mmHg in normal physiological conditions, and the RQ (respiratory quotient). FiO 2 is directly related to the percent composition of oxygen in the inspired air.
Arterial Blood Gas (ABG) interpretation for medical students, OSCEs …
2020年10月9日 · PaCO2 is the partial pressure of carbon dioxide in arterial blood. This is the amount of strong acid which would need to be added or subtracted from a substance in order to return the pH to normal (7.40). A value outside of the normal range (-2 to +2 mEq/L) suggests a metabolic cause for the acidosis or alkalosis.
