Which of the following indicators are useful in assessing respiratory muscle strength?
1) Maximum voluntary ventilation (MVV)
2) Forced vital capacity (FVC)
3) Dead space-to-tidal volume ratio (V_D/V_T)
4) Maximum inspiratory pressure (MIP)

Question

Quizplus · Accepted Answer

Maximum voluntary ventilation (MVV), Forced vital capacity (FVC), and Maximum inspiratory pressure (MIP) are all indicators used to assess respiratory muscle strength. MVV measures the maximum amount of air that can be inhaled and exhaled within one minute, indicating respiratory endurance. FVC assesses the volume of air that can be forcibly exhaled after full inhalation, reflecting lung capacity and muscle strength. MIP measures the maximum pressure that can be generated by the inspiratory muscles, directly assessing their strength. The dead space-to-tidal volume ratio is not directly related to muscle strength but rather to ventilation efficiency and gas exchange.
