1. A resuscitator for providing ventilation gas for a patient, said resuscitator comprising:
- a patient outlet for supplying said gas to the patient;
an exhaust outlet for supplying exhaled gas from the patient to atmosphere; and
a diverter fitted on said exhaust outlet, said diverter including a tubular portion, a diverter plate extending laterally from said tubular portion inclined at an angle to an axis of said tubular portion, and an opening between said plate and said tubular portion such that exhaled gas flowing through said exhaust outlet flows along an inner surface of said diverter plate and is diverted laterally out of said opening, wherein said diverter includes a color-change carbon dioxide indicator mounted on an inner surface of said diverter plate where it is exposed to flow through said diverter, and wherein said indicator is visible externally of said diverter.

Abstract
A squeeze bag resuscitator has a flow diverter push fitted onto its exhaust outlet in any desired orientation. The diverter has a color change carbon dioxide indicator strip fixed to the inside surface of a transparent deflector plate. The indicator is protected from light externally by an opaque elastomeric strip attached by engaging surface formations to the outside of the plate. The indicator is also protected on the interior of the plate by an opaque strip, which projects from the diverter so that it can be removed by pulling on the free end.
