In this study we aimed to evaluate the peak cough flow (PCF) in healthy Brazilian subjects.
We evaluated 484 healthy subjects between 18 and 40 years old. Subjects were seated and oriented were asked to perform a maximal inspiration followed by a quick, short and explosive expiration on the peak flow meter. Three measures were carried out and recorded the average of the three results for each individual.
The PCF values ranged between 240 and 500 L/min. The PCF values were lower in females than in males. The PCF was inversely proportional to age.
The values for Brazilian adult healthy subjects regarding PCF were between 240 and 500 L/min.
