Value of Pefr measurement in lung diseases Biology essay
Key points. Peak Expiratory Flow Rate, PEFR, is a measure of how quickly a person can exhale air from their lungs during forceful breathing. Monitoring peak expiratory flow rate (PEFR) is especially useful in treating patients with asthma, chronic obstructive pulmonary disease COPD, or other respiratory diseases. The authors examined whether peak expiratory flow PEF is a valid measure of health status in older adults. Survey and test data from cycles of the Health and Retirement Study, a longitudinal study of US adults over years with biennial surveys, were used to develop predicted PEF regression. Background Peak expiratory flow rate, PEFR, is an important tool for assessing lung function, which can be influenced by environmental and physical factors such as altitude, diet, genetics, age, height and weight. By conducting a study to assess the correlation between peak expiratory flow rate and anthropometric measurements, pulmonary function testing with PFTs allows physicians to evaluate the respiratory function of their patients in many clinical situations and when there are risk factors for pulmonary diseases, occupational exposures and pulmonary diseases. toxicity. National guidelines for the measurement and interpretation of PFT are regularly updated,
