The respiratory rate is a count of one full inspiration/expiration cycle for 1 full minute. Assessing respirations includes checking rate, rhythm, and depth. It includes assessing inspiration (taking oxygen into the lungs) and expiration (removing carbon dioxide from the lungs). The normal respiratory rate varies with age. The newborn’s respiratory rate is quite rapid, averaging about 40 breaths per minute. The respiratory rate gradually decreases with age until it reaches the adult rate of 12...

What is Body temperature? Body temperature is the difference between heat produced and heat lost. The hypothalamus acts as the body’s thermostat to maintain a constant body temperature. The balance is maintained between the body’s heat producing functions (metabolism, shivering, muscle contraction, exercise, and thyroid activity) and the heat-losing functions (radiation,...
