Physical examination
Information:
Definition:
The process of examining the patient's body to determine the presence or absence of physical problems. It includes
inspection
(looking),
palpation
(feeling),
auscultation
(listening), and
percussion
(producing sounds).
A sphygmomanometer is used to measure blood pressure, and is the most accurate method. Blood pressure is measured against the height of a column of mercury. This is the most accurate method because it can only be made inaccurate by changing the gravitational constant of the earth.
