ABSTRACT:
A pressure monitor is provided for gas pressure supplied to a patient. The monitor includes a pair of spaced contacts in the form of crank arms. A spring member is fixed at one end and is deflectable by a pneumatic cushion supplied with air from the gas supplied to a patient. The pneumatic cushion interacts with the resiliency of the spring member to urge the spring member to an intermediate position between a pair of fixed contacts. Too low a gas pressure will permit the spring member to engage one contact, while too high a gas pressure will cause the spring member to engage the other contact. Closure of the spring member against either contact energizes a respective alarm. In addition, there is provided a preset pneumatic-electrical switch connected to an oxygen supply line to indicate low oxygen pressure.
