Abstract
A manometer with a cadence indicator includes a housing and a gas pressure indicator interfaced to the housing. An input port of the housing is for connecting the manometer to a source of gas pressure, such that the gas pressure at the input port is reflected in the gas pressure indicator, providing a pressure reading. A cadence module is interfaced to the housing such that cadence is provided concurrently from the local of the gas pressure indicator. Cadence is provided by a flashing light or audible noise.
