  2. Transcutaneous oxygen measurement - Wikipedia

    en.wikipedia.org/wiki/Transcutaneous_oxygen...

    The normal oxygen tension in the foot is approximately 60 mmHg, and the normal chest/foot ratio is approximately 0.9. [2] Many factors can limit the accuracy of the test including edema, temperature, inflammation, medications, and stress. In addition for the measurement to be normal, all parts of the oxygenation pathway must be functioning: the ...

    en.wikipedia.org/wiki/Blood_gas_tension

    Arterial blood oxygen tension (normal) 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. [4] [5] [6] Venous blood oxygen tension (normal) P v O 2 – Oxygen tension in venous blood at sea level is between 30 mmHg ...

  4. Pulse oximetry - Wikipedia

    en.wikipedia.org/wiki/Pulse_oximetry

    A pulse oximeter probe applied to a person's finger. A pulse oximeter is a medical device that indirectly monitors the oxygen saturation of a patient's blood (as opposed to measuring oxygen saturation directly through a blood sample) and changes in blood volume in the skin, producing a photoplethysmogram that may be further processed into other measurements. [4]

  7. Arterial blood gas test - Wikipedia

    en.wikipedia.org/wiki/Arterial_blood_gas_test

    An ABG test measures the blood gas tension values of the arterial partial pressure of oxygen (PaO2), and the arterial partial pressure of carbon dioxide (PaCO2), and the blood's pH. In addition, the arterial oxygen saturation (SaO2) can be determined. Such information is vital when caring for patients with critical illnesses or respiratory disease.

  8. Pressure regulator - Wikipedia

    en.wikipedia.org/wiki/Pressure_regulator

    A typical nominal regulated gauge pressure from a medical oxygen regulator is 3.4 bars (50 psi), for an absolute pressure of approximately 4.4 bar and a pressure ratio of about 4.4 without back pressure, so they will have choked flow in the metering orifices for a downstream (outlet) pressure of up to about 2.3 bar absolute.

  9. Hypoxemia - Wikipedia

    en.wikipedia.org/wiki/Hypoxemia

    The alveolar oxygen is transferred to hemoglobin, a carrier protein inside red blood cells, with an efficiency that decreases with the partial pressure of oxygen in the air. Altitude. The external partial pressure of oxygen decreases with altitude, for example in areas of high altitude or when flying.
