Description
Spirometer
The Spirometer can be used for investigating tidal
volumes, respiratory rate, pulmonary ventilation, reserve
volumes and vital capacity. Oxygen consumption can
also be measured which is useful in metabolic studies.
A simple lever control enables the subject to be connected
either to atmosphere or to the float for recording.
A container for soda lime crystals is fitted which can be
used to absorb carbon dioxide.
The spirometer is designed to offer minimum resistance to airflow. This means greater comfort for the subject and more realistic results. The tank is one-piece stainless steel pressing
housed in a durable painted outer case. The float is constructed from lightweight plastic. The float is calibrated
0 to 7 x 0.5 litres and has a metal counterpoise. The pen
arm corresponds to approximately 0.5 litres. The two
corrugated breathing hoses 0.8m long are provided with
two mouthpieces and a nose clip. Soda lime crystals
are not supplied. A Kymograph or Datalogger system
is required to record results.
