Convert mmHg to SI units as follows: 1 mmHg = 0.133 32 kPa. Hence the normal blood pressure in SI units is less than 16.0 kPa SBP and less than 10.7 kPa DBP. These values are similar to the pressure of water column of average human height; so pressure has to be measured on arm roughly at the level of the heart.
Spirometry (meaning the measuring of breath) is the most common of the pulmonary function tests (PFTs). It measures lung function, specifically the amount (volume) and/or speed (flow) of air that can be inhaled and exhaled.
70 kPa Pressure inside an incandescent light bulb [52] 75 kPa Minimum airplane cabin pressure and lowest pressure for normal breathing (at 2440 m) and also the limit stated by the Federal Aviation Regulation (FAR) [53] 80 kPa 12 psi Pressure inside vacuum cleaner at sea level on Earth (80% of standard atmospheric pressure) [citation needed] 87 ...
Respiratory pressure meter. Measuring respiratory muscle strength is a long-established method of assessing the mechanics of breathing. Respiratory muscle dysfunction (i.e., reduced strength or endurance) should be distinguished from lung function abnormalities and measured separately.
Arterial blood oxygen tension (normal) P a O 2 – Partial pressure of oxygen at sea level (160 mmHg (21.3 kPa) in the atmosphere, 21% of the standard atmospheric pressure of 760 mmHg (101 kPa)) in arterial blood is between 75 and 100 mmHg (10.0 and 13.3 kPa).
It specifies the following, under test conditions of a breathing rate of 62.5 litres (2.2 cu ft) per minute and an ambient pressure of 6 bars (600 kPa): [18] Work of breathing: <3.0 joules per litre; Peak respiratory pressure: ±25 mbar (±2.5 kPa) (inhalation or exhalation) Inhalation work of breathing: <0.3 joule per litre; Pressure spikes ...
When the measurement is taken at the end of a breath (exhaling), it is called "end tidal" CO 2 (PETCO 2). [1] The capnogram is a direct monitor of the inhaled and exhaled concentration or partial pressure of CO 2, and an indirect monitor of the CO 2 partial pressure in the arterial blood.
Atmospheric air pressure where standard atmospheric pressure is defined as 1013.25 mbar, 101.325 kPa, 1.01325 bar, which is about 14.7 pounds per square inch. Despite the millibar not being an SI unit, meteorologists and weather reporters worldwide have long measured air pressure in millibar as the values are convenient.
