aging of the human body
vital processes of the human body include:
- Blood pressure
- Body temperature
- Respiratory rate
- heart rate (pulse)
Normal body temperature does not change significantly with age.However, as you get older, your body becomes more difficult to control body temperature.Loss of subcutaneous fat makes it difficult to maintain a constant body temperature.Many older people feel that they have to wear a lot of layers of clothes to feel warm.
Aging reduces the body's ability to sweat.Elderly harder to feel overheated.Therefore, older people are at greater risk of overheating, hyperthermia and heat stroke.They are also at risk of falling body temperature, hypothermia.
Fever is an important sign of the disease in the elderly.Continuing for a few days the fever is the only symptom.Any fever that is not explained by the well-known diseases, is to be investigated by your doctor.
part of the body of older people are not able to create a higher temperat
heart and breathing
When you get older, you are able to retain the ability to physical activity and exercise, you can do it at a young age.It takes more time to increase the heart rate and heart rate, and to slow down the performance after training.Maximum heart rate is attained with the help of exercise, reduced.
However, despite the fact that several lung function decreased, respiration rate usually does not vary with age.Breathing problems are seldom normal.Very elderly people should be able to breathe without effort under normal circumstances.
Many older people find that begins to feel dizzy if they stand up too suddenly.This is because the pressure suddenly drops.blood pressure drop at a sharp change in body position called orthostatic hypotension.
risk of developing high blood pressure - hypertension increases with age.Other problems associated with the heart, the most frequently observed in the elderly include:
-Too slow heart rate (bradycardia) or rapid heart rate (tachycardia);
-Problems heart rhythm - arrhythmia, such as atrial fibrillation.
Effect of medicines on the vital signs
Medicines that are used to treat common diseases in the elderly, may also affect the main indicators.
example, drugs for heart failure, and some drugs aimed at lowering blood pressure, known as beta-blockers may slow down the pulse.
Diuretics can cause low blood pressure and contribute to its improvement with a change in body position.
