A. Rate: is described in rate per minute (RPM) Healthy adult RR = 15- 20/ min. is measured for full minute, if regular for 30 seconds. As the age decreases the respiratory rate increases.
1. Eupnea- normal breathing rate and depth
2. Bradypnea- slow respiration
3. Tachypnea - fast breathing
5. Apnea - temporary cessation of breathing
B. Rhythm: is the regularity of expiration and inspiration
Normal breathing is automatic & effortless.
C. Depth: described as normal, deep or shallow.
Deep: a large volume of air inhaled & exhaled, inflates most of the lungs.
Shallow: exchange of a small volume of air minimal use of lung tissue.
Blood Pressure: Blood pressure is the pressure exerted by blood against the wall of blood vessels. It includes arterial, venous and capillary pressures.
Arterial BP: it is a measure of a pressure exerted by the blood as it flows through the arteries. Arterial blood pressure (BP) = cardiac output (CO) x total peripheral resistance (TPR).
