Aerodynamic analysis is interpreted as a reflection of the valving activity of the larynx. It involves measuring changes in air volume, flow and pressure which indicate respiratory function. These measures help in determining the important aspects of lung function. Peak expiratory flow rate is a widely used respiratory measure and is an effective measure of effort dependent airflow. Aim: The aim of the current study was to study the peak flow as an aerodynamic measure in healthy normal individuals Method: The study group was divided into two groups with n= 60(30 males and 30 females) in the age range of 18-22 years. The peak flow was measured using Aerophone II (Voice Function Analyser). The anthropometric measurements such as height, weight and Body Mass Index was calculated for all the participants. Results: The peak airflow was higher in females as compared to that of males. It was also observed that the peak air flow rate was correlating well with height and weight in males. Conclusions: Speech language pathologist should consider peak expiratory airflow, a short sharp exhalation rate as a part of routine aerodynamic evaluation which is easier as compared to the otherwise commonly used measure, the vital capacity.
