Spirometer

For investigating tidal volumes, respiratory rate, pulmonary ventilation, reserve volumes and vital capacity. Oxygen consumption can also be measured which is useful in metabolic rate studies. A simple lever control enables the subject to be connected either to the atmosphere or to the float for recording. A container for soda lime crystals is fitted which absorbs the CO2. The spirometer is designed to offer minimal resistance to airflow. This provides the user with greater comfort and ensures accurate results. The float is constructed from lightweight plastic and is calibrated in 0.5 litre steps with a maximum capacity of 7 litres. A pen arm allows attachment of a fibre tipped pen for recording results or for attachment to a position sensor for datalogging. Two flexible corrugated breathing hoses 0.8m long are provided. Supplied with a rubber mouthpiece and nose clip. Complete with full instructions.
