Question 151. Multiple Choice. At a PO2 of 70 mm Hg and normal temperature and pH, hemoglobin is ________ percent saturated with oxygen. A) 10B) 25C) 50D) 75E) more than 90. Explore answers and all related questions. Related questions. 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).

The current standard of care therapy for patients with PCP does not involve the addition of corticosteroids to standard antibiotics in those patients with pO2>70 mmHG. Because the functional hemoglobin is nearly 100% saturated, we do expect a pO2 of near 100 mm Hg(figure 2). Indeed if the hemoglobin saturation is 98%, the predicted pO2 is 95 mm Hg. As a side note, in the absence of lung disease, hypoventilation or environmental hypoxia, the pO2 is also expected to be normal in cases of methemoglobinemia. 2021-01-05 · These patients had a PaO2 between 7.4kPa (55.5 mmHg) and 8.7kPa (65.3 mmHg), with mean PaO2 8 kPa (60 mmHg). LTOT, over at least 3 years, was not associated with a survival benefit, and there was no difference in survival between the patients with a PaO2 above or below 8 kPa (60 mmHg). However, the mean daily use of oxygen was only 13.5h.

2021-04-19 · At a normal PO2 of about 100 mmHg, hemoglobin is almost completely loaded with oxygen. Thus an increase in blood PO2 —produced, for example, by breathing 100% oxygen from a gas tank—cannot significantly increase the amount of oxygen contained in the red blood cells. 31.5 mmHg, pO2 70 mmHg, bicarbonato de 15.5 mEq/l y el pH urinario era de 6.6. El CCr fue de 50 ml/minuto, con 2 gr.

O is vapor pressure of water (47 mmHg at 37 o C) – PaCO 2 is partial pressure of CO 2 – R is the respiratory quotient (typically ~0.8) – 0.21 x (760-47) - (40/0.8) – ~100 mm Hg • Alveolar–arterial (A-a) O 2 gradient is normally ~ 10, so PaO2 (arterial PO2) should be ~90 mmHg . NB: To convert mm Hg to kPa, multiply by 0.133 pCO2 40 mm Hg pO2 95 mm Hg Hemoglobin - O2 97% HCO3 32 meq / liter Answer: gastric secretions in the stomach are very acidic - pH can be below 1.0. If patient is vomiting a lot, there is a net loss of H+ ions from the stomach lumen and ultimately from the bloodstream.

The actual amount of dissolved oxygen under these circumstances is not particularly important (it can be looked up in solubility tables, if desired); it is simply a linear function of the PO2. mmHg↔kPa 1 kPa = 7.500617 mmHg mmHg↔cPa 1 mmHg = 13332.236535 cPa mmHg↔mPa 1 mmHg = 133322.365347 mPa mmHg↔uPa 1 mmHg = 133322365.34674 uPa mmHg↔N/m2 1 mmHg = 133.322365 N/m2 mmHg↔Bar 1 Bar = 750.0617 mmHg mmHg↔mbar 1 mmHg = 1.333224 mbar mmHg↔ubar 1 mmHg = 1333.223653 ubar mmHg↔kgf/m2 1 mmHg = 13.595098 kgf/m2 2021-04-11 Oxygen Saturation under ideal conditions is +/- 2%; Oxygen Saturation can miss a large A-a Gradient. 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.
