TThis article sets out the appropriate and suggested care for patients under acute, high dependency or critical care placement. Specifically, the patient that will be studied has had a Myocardial Infarction. Initially, the profile of the patient has been made available for the purpose of developing a care plan.
Patient’s Altered Physiology
Theories attempting to explain the physiologic changes that occur during the aging process include genetic theories, cellular theories, and organ system theories. Other physiologic concepts of aging that are proposed are nutrient deprivation, lipofuscin, wear and tear theory, and cross-linking theory. Psychologic theories abound and include disengagement theory, activity theory, life course theory, and continuity theory. None of the said theories or constructs can claim sufficient evidence to account for aging effects that are experienced by older people. The majority of theorists and practitioners agree that with advanced age come factors such as increased vulnerability, increased susceptibility to disease, decrease in vitality, and slowed response to and recovery from stress.
The structural changes described translate into specific cardiovascular problems, such as hypertension, decreased cardiac output, CHF, valvular dysfunction, and cardiac arrhythmias or conduction disturbances. Other changes in cardiovascular physiology compound these problems. Already mentioned is the decreased arterial oxygen tension, which can aggravate any vascular problem and make elderly patients with circulatory compromise (coronary artery or peripheral artery insufficiency) have more severe symptoms than they would, based on their anatomic vascular disease alone. ...
