Definition

Normal changes in vital signs occur as an individual ages. Vital signs include temperature, pulse, blood pressure, and breathing rate.

What is the information for this topic?

As an individual ages, vital signs change in certain ways.

Temperature

The body temperature often remains normal. However, the body must work harder to control temperature. As a person ages, the skin becomes thinner and less elastic, or stretchable. The layer of fat tissue under the skin also becomes thinner. This is the reason older people often feel cold in a room that has normal temperature. The ability to get rid of excess heat by sweating is also reduced, making older persons more likely to suffer in hot weather. It may also become more difficult to sense changes in body temperature.

Pulse

Pulse is a measure of heart rate over a 1-minute period of time. As a person ages, the heart rate at rest usually remains the same but may gradually increase if his or her heart or lung functions become impaired of if he or she has any of a number of other chronic illnesses. In an older person, the heart rate may not speed up as quickly with exercise, and may also take longer to return to normal after exercise.

Blood Pressure

Many people have an increase in their blood pressure with age. This partially caused by changes in the heart and blood vessels that come with age, but many time it is also related to increasing obesity, and lack of exercise over many years. Some individuals develop orthostatic hypotension, or a rapid drop in blood pressure when they stand up. Regardless of the cause, high blood pressure is usually treated to reduce the risk of strokes and heart attacks.

Breathing Rate

The breathing rate is less affected by age than other vital signs. However, lung function decreases with age. The individual may need to exercise less strenuously or for a shorter period of time.

Prevention

Medicines can be used to control medical problems that cause abnormal vital signs. However, it is also true that some medicines can cause changes in vital signs as an unintended side effect. Any problems with these medicines should be reported to the healthcare professional. These include:

Many steps can be taken to help keep vital signs under control. Certain tips can help avoid problems with vital signs. Elderly individuals should avoid:
