Inspiration & expiration

Ventilation • The process of exchange of air between the lungs and the ambient air. • Airflow in respiratory system is directly proportional to the pressure gradient and inversely related to the resistance of the airways. • A single respiratory cycle = inspiration+expiration 07/31/2013

Spirometer • A spirometer is a device for measuring the volumes of air that move into and out of the respiratory system. Spirometry is the process of taking the measurements. • Spirometer s the amount and rate of air moved into or out of the lungs. • Types: • Volume: Records the amount of air exhaled or inhaled within a certain amount of time. • Flow: Measures how fast the air flows in or out as 07/31/2013 the volume of air inhaled or exhaled increases.
