Effect of changes
Loss of subcutaneous fat makes it harder to maintain body heat. Many older people find that they need to wear layers of clothing in order to feel warm. Likewise, skin changes include the reduced ability to sweat. Therefore, older people find it more difficult to tell when they are becoming overheated.
There may be decreased tolerance to exercise. Some elderly people have a reduced response to decreased oxygen or increased carbon dioxide levels (the rate and depth of breathing does not increase as it should).
Many older people find that they become dizzy if they stand up too suddenly. This is caused by a drop in blood pressure when they stand called orthostatic hypotension.
Medications that are used to treat common disorders in the elderly may also have a profound effect on the vital signs.
For example, digitalis (used for heart failure) and certain blood pressure medications called beta blockers may cause the pulse to slow. Pain medications can slow breathing. Diuretics can cause low blood pressure and aggravate orthostatic hypotension (a drop in blood pressure when changing body position).
