Baroreceptors help to monitor a person’s blood pressure. They also help to make changes that help to maintain blood pressure more consistently when the client changes position or engages in activities that get the heart rate up. When clients age, the baroreceptors become less sensitive. Because of this, older people may have falling blood pressure which may explain some of their dizziness; less blood flow to the brain.
As was explained over the past few days, capillary walls can thicken slightly. If the thickening occurs, this means that there may be a slower rate of exchange between nutrients and wastes.
The aorta, the main artery in our hearts, can become thicker, stiffer and less flexible because of the connective tissue changes in the blood vessel wall, making the blood pressure increase. When this happens, the heart is forced to work harder. This can lead to hypertrophy, the thickening of the heart muscle and to the thickening and stiffening of other arteries as well. All these changes can have a moderate increase in blood pressure.
This can lead to some of the problems that caregivers witness on a daily basis. Knowing why these changes are occurring in your clients can help you become a better caregiver; allowing you to show more dignity and respect. After all, With Age Comes Respect.
