Oxygen Saturation can be 100% when PaO2 is 90 mmHg or 300 mmHg; At a high FIO2 of Supplemental Oxygen, Oxygen Saturation cannot distinguish a PaO2 above 90 mmHg; Normal PaO2 on FIO2 100% should be >500 mmHg; Normal PaO2 on FIO2 50% should be >250 mmHg (linear relationship) 2017-04-15 Cerebral perfusion pressure, or CPP, is the net pressure gradient causing cerebral blood flow to the brain (brain perfusion).It must be maintained within narrow limits because too little pressure could cause brain tissue to become ischemic (having inadequate blood flow), … If a patient's PO2 results are 70, then we know there is an insufficient amount of dissolved oxygen present. Clinically, there can be many different reasons for this. The patient may be anemic, or may have decreased respirations, or may have pneumonia. All or any of these conditions may lead to low PO2. Oxygen Content of the Blood: P a O 2 – Partial pressure of oxygen at sea level (160 mmHg in the atmosphere, 21% of standard atmospheric pressure of 760 mmHg) in arterial blood is between 75 mmHg and 100 mmHg. Venous blood oxygen tension (normal) P v O 2 – Oxygen tension in venous blood at sea level is between 30 mmHg and 40 mmHg. Carbon dioxide tension pO2 <60 mm Hg or SpO2 (pulse oximetry) <91% breath-ing room air pCO2 >50 mm Hg and pH <7.35 (hypercapnic) P/F ratio (pO2 / FIO2) <300 pO2 decrease or pCO2 increase by 10 mm Hg from base-line (if known). P/F RATIO The P/F ratio equals the arterial pO2 divided by the FIO2 (the fraction of inspired oxygen expressed as a decimal) the patient At a Po2 of 70 Mm Hg and Normal Temperature.

A patient's PaO2 (at sea level) should be 5 x the inspired oxygen percentage (FIO2). For example, a patient on room air is breathing 21% oxygen and so the PaO2 should be ~ 105 mmHg. A low PO2 (below 60mm mercury) means that supplemental oxygen should be given, and a PO2 lower than 26 means the patient is near death. Look at carbon dioxide pressure (PCO2). PCO2 is normally between 35 and 45 mm mercury. 2017-10-09 · 80 to 100 mm Hg. 28 – 48 mm Hg: The partial pressure of oxygen that is dissolved in arterial blood.

Which of the following is the least likely cause of these abnormal blood gases? a) congestive heart failure . b) narcotic overdose . c) myasthenia gravis . d) flail chest .

A low PO2 (below 60mm mercury) means that supplemental oxygen should be given, and a PO2 lower than 26 means the patient is near death. Look at carbon dioxide pressure (PCO2). PCO2 is normally between 35 and 45 mm mercury.
