Ventilation/Perfusion (V/Q) matching refers to the matching of ventilation (airflow) and perfusion (blood flow) in the lungs. This process is crucial for efficient gas exchange, which involves the exchange of oxygen (O2) from the air into the bloodstre...
Peak systemic oxygen extraction (pEO2) refers to the maximum amount of oxygen the body extracts from the bloodstream during intense physical activity or high metabolic demand. This measurement is often used in exercise physiology and sports science to ...
Positive End-Expiratory Pressure (PEEP) is a mechanical ventilation technique used in respiratory therapy and intensive care medicine. It involves applying a constant positive pressure to the airways during the expiratory phase of the respiratory cycle...
Noncardiogenic pulmonary edema occurs when fluid accumulates in the lungs, leading to respiratory distress without being caused by heart-related issues. Unlike cardiogenic pulmonary edema, associated with heart failure, noncardiogenic pulmonary edema o...
Telehealth uses digital information and communication technologies like computers and mobile devices to remotely access and manage healthcare services. It encompasses various healthcare services, including consultations, diagnoses, monitoring, and trea...
Dysphagia refers to difficulty swallowing, which can occur due to various reasons, such as neurological disorders, structural abnormalities, or muscular problems affecting the throat or esophagus. If severe, it can lead to problems with eating, drinkin...
Dyspnea is the medical term for shortness of breath or difficulty breathing. It can range from mild, temporary discomfort to severe, chronic difficulty that can be debilitating. Dyspnea is often associated with conditions affecting the heart or lungs, ...
Respiratory Muscle Strength (RMS) refers to the force-generating capacity of the muscles involved in breathing, particularly the diaphragm, intercostal muscles, and accessory muscles of respiration. These muscles are crucial in expanding and contractin...
Residual Volume (RV) is the air volume remaining in the lungs after a maximal exhalation. It's vital for assessing lung hyperinflation, often seen in obstructive lung diseases.
Functional Residual Capacity (FRC) is a respiratory physiology parameter that represents the volume of air present in the lungs at the end of passive expiration. It is the amount of air that remains in the lungs after a normal tidal breath is exhaled. ...
