Did you know?
WebMaximal inspiratory airflow at 50% of forced vital capacity (MIF 50% FVC) is greater than maximal expiratory airflow at 50% FVC (MEF 50% FVC) because dynamic compression of the airways occurs during exhalation. (B) Obstructive disorder (eg, emphysema, asthma). Although all airflow is diminished, expiratory prolongation predominates, and MEF < MIF. WebFeb 13, 2024 · On the contrary, fat-rich meals decrease the production of CO2, leading to reduce alveolar ventilation and minor improvement in respiration in patients who initially have an RQ ratio greater than 0.75. Non-Insulin Dependent Weight Gain. The respiratory quotient can be used to predict weight gain in non-insulin-dependent diabetic patients.
