If it is known that the gas has a PO2 of 152 mmHg, for example, the deflection of a needle by the oxygen electrode can be calibrated on a scale at 152 mmHg (fig. 16.22). 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.

3 Nov 2020 the systemic oxygen delivery to the tissues than oxygen tension (PO2) Hypoxaemia is usually defined as SaO2 <90% or PaO2 <60 mmHg

35 - 45 mm Hg The mean change is 8.4 mmHg at 30 minutes, 9.6 at 60 minutes and 10.3 at 90 minutes when the initial pO 2 is We left off last month with the P/F ratio, one of the four defining criteria for acute respiratory failure: ■ 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 gold standard for the diagnosis of acute hypoxemic respiratory failure is an arterial pO2 on room air less than 60 mmHg measured by arterial blood gases (ABG). In the absence of an ABG, SpO2 less than 91% measured by pulse oximetry on room air can serve as a substitute for the pO2 because SpO2 of 91% equals pO2 of 60 mmHg. When the lungs are functioning properly, the PO2 of systemic arterial blood is only 5 mmHg less than the PO2 of alveolar air. At a normal PO2 of about 100 mmHg, hemoglobin is almost completely loaded with oxygen.

Småningom steg också blodtrycket till nivån 100/60 mmHg, men krävde The CM-mediated effect on haemodynamics, PO2, urine output and blood pressure was unaffected by the A1-receptor with a 30-min control period (C1) followed by a 60-min control MAP (mm/Hg) C1 122±4 122±5 121±4. av P Lernö · 2011 · Citerat av 1 — 85-130 mmHg och i lungvenen 60-70 mmHg när hästar galopperat i hög fart.

Hence a pressure gradient of 60 mm Hg exists, toward blood from alveoli, so O2 diffuses from alveoli into blood. 2. Systemic capillaries a).

At a normal PO2 of about 100 mmHg, hemoglobin is almost completely loaded with oxygen. Because home O2 is adjusted to maintain a pO2 > 60 mmHg (SpO2 > 91%).
