A low static pressure reading suggests that there may be leaks in the ducts or that the fan speed needs to be adjusted. WebHead Pressure. Head pressure is the pressure exerted by a liquid that indicated by height of the liquid in a liquid column. It depends on; 1. the height of the liquid column. 2. the relative density of the liquid. Pressure head = R.D x h x 9.8 kPa. where, R.D = relative density of the liquid, h = the height of the liquid g = gravitational force.

WebFirst step: Determining maximum pressure inflation . Palpate the radial or brachial artery, inflate the blood pressure cuff until the pulse is obliterated, and then continue to inflate 30 mm Hg more (OER #1). Note this number – it is considered the maximum pressure inflation. Next, deflate the cuff quickly. Second step: Measure blood pressure WebBlood pressure is measured in millimetres of mercury in most of the world, and lung pressures in centimeters of water are still common.
