FEV1 is the peak during the first second of exhalation only.
Generally, most flow meters are very accurate in FEV1. However, device accuracy is not especially important, rather it is essential that you take multiple measurements to calculate an accurate working average.
the difference between flow and motion is well flow is like floating and motion is the way you move

To read a spirogram, look at the flow-volume loop to assess lung function. The size and shape of the loop can indicate if there are any abnormalities such as obstructive or restrictive lung diseases. Key parameters to evaluate include forced vital capacity (FVC), forced expiratory volume in one second (FEV1), and the FEV1/FVC ratio. Patterns such as a decreased FEV1/FVC ratio suggest obstruction, while reduced FVC may indicate restriction.

forced expiratory flow
Wheezing, coughing, chest tightness, shortness of breath. A reduction in peak expiratory flow rate (PEFR) by around 20% or a Forced expiratory volume reduction in one second (FEV1) of 15%. I have Asthma and its hard to breathe, and your throat feels like its going to squash up. So choking, coughing,tightness of your chest and your throat closing up to make you choke. TRUST ME: YOU DO NOT WANT ASTHMA. ITS HORRIBLE.
