Functional capacity can also be expressed as "METs" and can be used as a reliable predictor of future cardiac events. [5] One MET is defined as the amount of oxygen consumed while sitting at rest, and is equal to 3.5 ml oxygen per kilogram body weight per minute.
Physiological functional capacity (PFC) is the ability to perform the physical tasks of daily life and the ease with which these tasks can be performed. PFC declines at some point with advancing age even in healthy adults, resulting in a reduced capacity to perform certain physical tasks.
The Functional Capacity Index (FCI) is a measure of a person's level of function for the following 12 months after sustaining some form of illness or injury. [1] The FCI incorporates ten physical functions and gives each a numerical value on a scale of 0 to 100, with 100 representing no limitations on a person's everyday function.
Despite difficulties in applying it, such as the challenge of consistently classifying patients in class II or III, [2] because functional capacity is such a powerful determinant of outcome, it remains arguably the most important prognostic marker in routine clinical use in heart failure today. With time the classification system evolved and ...
The Duke Activity Status Index (DASI) is an assessment tool used to evaluate the functional capacity of patients with cardiovascular disease (CVD), such as coronary artery disease, myocardial infarction, and heart failure. [1] In clinical practice, DASI can be used to assess the effects of medical treatments and cardiac rehabilitation as well. [2]
Scientists and researchers use CRF to assess the functional capacity of the respiratory and cardiovascular systems. These functions include ventilation, perfusion, gas exchange, vasodilation, and delivery of oxygen to the body's tissues. As these body's functions are vital to an individual's health, CRF allows observers to quantify an ...
Functional residual capacity (FRC) is the volume of air present in the lungs at the end of passive expiration. [1] At FRC, the opposing elastic recoil forces of the lungs and chest wall are in equilibrium and there is no exertion by the diaphragm or other respiratory muscles.
Chromosomes during methylation. Biomarkers of aging are biomarkers that could predict functional capacity at some later age better than chronological age. [1] Stated another way, biomarkers of aging would give the true "biological age", which may be different from the chronological age.
