Your assignment is to prepare and submit a paper on peak flow. A spirometer is the equipment used in the measurement of peak flow. This apparatus measure the amount of air, which is taken in during inspiration phase and expired out over a specified time. Along with the amount, it also keeps a record of the speed, which is then converted to rate of air inspired and expired (Spirometer 2006) (Pederson 1996). Stating more scientifically, it measures lung functions specifically the measurement of the amount (volume) and /or speed (flow) of air that can be inhaled and exhaled.

Spirometry is the process of measuring pulmonary function tests (PFTs) (Spirometry 2006). The process is an important monitoring tool for the diagnosis and prognosis of pulmonary obstructive diseases. Results are, usually, given as the percentages of predicted values for the patients of similar physiological characteristics. The results approaching 100 % predicted are the most normal but those individuals who show over 80% may be considered normal. The review by a medical doctor, further, validates the results (Spirometry 2006).
