What is a normal capillary blood gas?
What is a normal capillary blood gas?
The ‘gold standard’ sample for blood gas analysis is arterial blood obtained via an indwelling arterial catheter or by arterial puncture….ARTERIAL AND CAPILLARY BLOOD GAS pH, pCO2 & pO2 – STUDY FINDINGS.
| Arterial | Capillary | |
|---|---|---|
| pH Hydrogen ion conc (mmol/L) | 7.35-7.45 35-45 | 7.402 (mean only) 37-43 |
What are the expected reference ranges for arterial blood gas values?
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 PO2 normal range?
Oxygen (PO2) This is the partial pressure of oxygen. The normal range is 75-100mmHg.
What is CBG report?
Capillary blood glucose (CBG) testing was developed to replace home urine glucose testing by patients or by the staff in physician offices. CBG testing can also be applied in the hospital laboratory as a cost-effective method to rapidly test blood glucose levels.
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 the normal range for BE?
[Base excess (BE) is the mmol/L of base that needs to be removed to bring the pH back to normal when PCO2 is corrected to 5.3 kPa or 40 mmHg.
What does a high PCO2 mean?
The most common cause of increased PCO2 is an absolute decrease in ventilation. Increased CO2 production without increased ventilation, such as a patient with sepsis, can also cause respiratory acidosis. Patients who have increased physiological dead space (eg, emphysema) will have decreased effective ventilation.
What is normal range of PO2 and PCO2?
What will be the PO2 and PCO2?
In atmospheric air, pO2 is about 159 mm Hg. In alveolar air, it is about 104 mm Hg. In atmospheric air, pCO2 is about 0.3 mm Hg. In alveolar air, it is about 40 mm Hg.
