1. Peak expiratory flow (PEF)

PEF, also known as peak expiratory flow (PEF), is an important respiratory function indicator. In the process of measuring lung capacity, the moment when the expiratory velocity reaches its maximum, the measured flow velocity is the PEF value. The importance of this value is self-evident, as it mainly reflects the strength of the respiratory muscles in the human body, that is, the muscle strength during lung contraction and expansion. At the same time, PEF is also a key parameter for evaluating whether the airway is smooth. If there is obstruction, it will lead to a decrease in PEF value. The monitoring of PEF plays an auxiliary role in the diagnosis of diseases. By comparing the changes in PEF values at different time points throughout the day, doctors can observe whether there are changes in circadian rhythms or significant fluctuations after certain activities or medications, thereby helping to determine the presence of respiratory diseases such as asthma or chronic obstructive pulmonary disease. Therefore, PEF peak expiratory flow rate testing is an important tool for clinical assessment of respiratory health status, and is of great significance for early detection and management of respiratory diseases.
