SPIROMETER SM-1
CLIFTON RANGE® - 1 YEAR WARRANTY
INTRODUCTION
The Clifton Spirometer can be used for investigating tidal volumes, respiratory rate, pul-
monary ventilation, reserve volumes and vital capacity. Oxygen consumption can also
be measured which is useful in metabolic rate studies.
The spirometer essentially consistts of a counterbalanced float, sealed by water which
contains oxygen. A system of valves and tubing enables the subject to breathe this oxy-
gen, thus causing the float to move up and down. Indicating soda-lime can be incorpo-
rated into the circuit to absorb carbon dioxide from the expired breath.
A simple level 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 can be used
to absorb carbon dioxide. The spirometer is designed to offer minimum resistance to air
flow. This means greater comfort for the user and more realistic results.
The spirometer enables rate of breathing, volumes of breaths and consumption of oxy-
gen to be monitored. It has a scale calibrated in litres, which can be read against the
water level, enabling readings to be taken directly, or it can be fitted with a pen arm al-
lowing the attachment of a fibre tipped pen or used in conjunction with a Kymograph or
electronic data logger system to record results.
Recommended data loggers: Logit from Griffin Education or Data Harvester from Scien-
tific and Chemical with neccessary motion sensor fitted to logger for recording results.
