About this calculator
The Pico Flow Expiratory Predicted calculator is a practical tool for calculating the amount of air an individual can exhale in a second. This value is essential in pulmonary function tests, particularly in the field of Pulmonology.
The calculation is made based on the formula: PFE = (h x 0.5 x age) / 100, where h is the individual's height in centimeters. This helps to provide a reasonable estimate of pulmonary capacity.
This calculator should be used in cases of suspected respiratory diseases, such as asthma or bronchitis. Additionally, it may be useful in pre-operative evaluations or workplace safety assessments.
However, it is crucial to remember that this is only an estimate and does not replace a comprehensive medical evaluation. Care should be taken when interpreting the results and considering other factors that may affect pulmonary function.
