Atmospheric pressure, also known as air pressure or barometric pressure (after the barometer), is the pressure within the atmosphere of Earth.The standard atmosphere (symbol: atm) is a unit of pressure defined as 101,325 Pa (1,013.25 hPa), which is equivalent to 1,013.25 millibars, [1] 760 mm Hg, 29.9212 inches Hg, or 14.696 psi. [2]
The definition of vital signs may also vary with the setting of the assessment. Emergency medical technicians (EMTs), in particular, are taught to measure the vital signs of respiration, pulse, skin, pupils , and blood pressure as "the 5 vital signs" in a non-hospital setting.
Abbreviations are used very frequently in medicine. They boost efficiency as long as they are used intelligently. They boost efficiency as long as they are used intelligently. The advantages of brevity should be weighed against the possibilities of obfuscation (making the communication harder for others to understand) and ambiguity (having more ...
For sound in air, a pressure of 20 μPa is considered to be at the threshold of hearing for humans and is a common reference pressure, so that its SPL is zero. The airtightness of buildings is measured at 50 Pa. [15] In medicine, blood pressure is measured in millimeters of mercury (mmHg, very close to one Torr).
Human platelet antigens (HPA) are polymorphisms in platelet antigens.These can stimulate production of alloantibodies (that is, antibodies against other people's antigens) in recipients of transfused platelets from donors with different HPAs.

P a CO 2 – Partial pressure of carbon dioxide at sea level in arterial blood is between 35 and 45 mmHg (4.7 and 6.0 kPa). [9] Venous blood carbon dioxide tension. P v CO 2 – Partial pressure of carbon dioxide at sea level in venous blood is between 40 and 50 mmHg (5.33 and 6.67 kPa). [9]
