ABSTRACT:
A respiration monitor comprising a sensing unit which senses the expansion and contraction of the chest, abdomen, side or back, by pneumatic means. Expansion of the chest is changed into a positive flow of air (pressure). Contraction of the chest is changed into a negative flow of air (vacuum). The sensor in the form of a belt with minimum space maintaining tapes is worn by the patient and connected to an appropriate monitor by means of tubing. The minimum space maintaining tapes allows the patient freedom of movement and prevents such body movements from affecting the operation of the sensor.
