Vital Signs
• Values used to measure changes in body function, general health, and response to treatment
• Include blood pressure (BP) and temperature, pulse, and respiration (TPR) and level of pain
• Affected by many factors: age, activity, nutrition, emotion, fitness, medication, and illness

Assessing Vital Signs
• Once a day (daily)• Twice a day (bid)• Three times a day (tid)• Four times a day (qid)• Every 4 hours (q4h)• Every 15 minutes (q15min)

Blood Pressure
• Measurement of the force of the blood against the walls of the arteries as it circulates through the body
• Maximum pressure at which the pulse can be heard is systolic
• Minimum pressure at which it is audible is diastolic

Instruments for Taking Blood Pressure
• Stethoscope amplifies the sound • Sphygmomanometer is an
inflatable cuff that measures pressure using air (aneroid) or mercury

Pulse
• Pulse is the heartbeat that can be felt, or palpated, on surface arteries as the artery walls expand
• The pulse is usually assessed using the radial artery near the wrist
• Normal adult pulse rate can range between 60 and 100 beats per minute
• The pulse of an infant is significantly faster than that of an adult

Respiration
• One respiration includes the inspiration and expiration of a breath
• The rhythm and character of respiration are important observations
