WebMar 19, 2024 · pO2 will tell us about oxygenation (ventilation). pCO2 will also tell us about the acid-base balance. pH = 7.35 to 7.45. pO2 = >80 mm Hg. pCO2 = 35 to 45 mm Hg. The above three parameters are needed to help the patients management. Acid-base system: The H+ ions concentration is commonly expressed as the pH. WebDec 30, 2024 · A low PaO 2 indicates hypoxemia (low oxygen in the blood), which may be caused by hypoventilation or a mismatch between ventilation and perfusion. The PaO 2 …

Web1) Assessment of oxygenation status The pO 2 on a VBG bears no relationship to the paO2. The VBG is of no value in assessing oxygenation status. 2) Assessment of hypercarbia In patients with COPD we need to … WebpH > 7.45 is an alkalosis. pH < 7.35 is an acidosis. While a pH range of 7.35-7.45 reflects physiologically normal values, the 'clinical' range that is targeted for care may differ (for example, a pH range of 7.25-7.35 may be chosen as a means of targeting the amount of ventilatory support provided).
WebDec 8, 2024 · High or low values indicate blood hyperoxia or hypoxia, respectively. pO2 in venous blood is lower than arterial blood due to oxygen extraction by peripheral tissues. pCO2: This is measured using a pCO2 electrode. A high pCO2 is compatible with a respiratory acidosis and a low pCO2 with a respiratory alkalosis. WebAug 6, 2010 · In the initial stages of COPD, you have low pO2 and high pCO2. the high pCO2 causes chronic respiratory acidosis, with compensation from the kidney. Also, the pO2 here is the main regulator of breathing rate.
WebA low PO2 (below 60mm mercury) means that supplemental oxygen should be given, and a PO2 lower than 26 means the patient is near death.
