AKilopascals, kPa
BAtmospheres, atm
CPounds per inch^2
DMillimetres of Hg
Answer & Solution
Correct answer: D. Millimetres of Hg
1. A sphygmomanometer is a cuff joined to a manometer, and mercury manometers report height directly.
2. That height is read in millimetres of mercury, so blood pressure is quoted in mm Hg.
3. This is why a normal reading is written as a pair of numbers of the order of one hundred.
4. Kilopascals and atmospheres are valid pressure units but are not the ones used on a blood pressure report.
