What is normal range of pO2 and PCO2?
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 a good blood gas percentage?
What is the normal range for blood gases?
| Parameter | Value |
|---|---|
| Partial pressure of carbon dioxide (PaCO2) | 38-42 mmHg* |
| pH of arterial blood | 7.38-7.42 |
| Oxygen saturation (SaO2) | 94-100% |
| Bicarbonate concentration (HCO3) | 22-28 mEq/L* |
What is PaO2 and PaCO2?
PaO2 = measured the partial pressure of oxygen in arterial blood. PaCO2 = measured the partial pressure of carbon dioxide in arterial blood.
Is PO2 the same as PAO2?
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 a good ABG level?
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.
What is sp02?
SpO2, also known as oxygen saturation, is a measure of the amount of oxygen-carrying hemoglobin in the blood relative to the amount of hemoglobin not carrying oxygen. The body needs there to be a certain level of oxygen in the blood or it will not function as efficiently.
What do blood gases tell you?
Blood gases are a group of tests that are performed together to measure the pH and the amount of oxygen (O2) and carbon dioxide (CO2) present in a sample of blood, usually from an artery, in order to evaluate lung function and help detect an acid-base imbalance that could indicate a respiratory, metabolic or kidney …
How do I check my ABG report?
Rules for rapid clinical interpretation of ABG
- Look at pH – < 7.40 – Acidosis; > 7.40 – Alkalosis.
- If pH indicates acidosis, then look at paCO2and HCO3-
- If paCO2is ↑, then it is primary respiratory acidosis.
- If paCO2↓ and HCO3- is also ↓→ primary metabolic acidosis.
- If HCO3-is ↓, then AG should be examined.
What is difference between SaO2 and SpO2?
Conclusion: Oxygen saturation results determined of different ways are often not identical. The difference between SaO2 and SpO2 are often more 3 pp when SpO2 results obtained from fingertip less than 94%.
What is the normal range of blood gas?
The first step in evaluating a blood gas report is to look at pH. The normal range for arterial blood pH is 7.35 to 7.45. A pH greater than 7.45 indicates alkalosis or more alkaline blood and a pH below 7.35 indicates acidosis or more acidic blood . When the pH is greater than 7.0, the blood is alkaline and when it is less than 7.0, acidic.
What is the normal blood gas level?
Arterial Blood Gas. The normal blood pH range is 7.35 to 7.45. Acidity or alkalinity of the blood can be measured with pH values. The normal range of PaO2 is 80 to 100 mm Hg. PaO2 tells us about the partial pressure of oxygen dissolved in arterial blood. The normal range of SaO2 is 95% to 100%.
What is normal blood gas results?
The following are normal ranges for results of a blood gas test: pH: 7.35–7.45. partial pressure of oxygen (PaO2): 80–100 millimeters of mercury (mmHg) partial pressure of carbon dioxide: 35–45 mmHg. bicarbonate: 22–26 milliequivalents per liter. oxygen saturation: 95 percent.
What are the normal values of blood?
Most physicians agree that the range of a normal level is 250 to 1,000 nanograms (ng) per deciliter (dL) of blood. For young males under the age of 30, the normal range is upwards of 600 ng/dL.
