Description

ABSTRACT:
A connector for a respirator apparatus which is adapted to be inserted into the open stem of a respiratory Y-tube and connected to an endotracheal tube is provided. In one embodiment the connector is adapted to be used as a pressure measuring or gas sampling device and in another embodiment as a pneumotach for measuring the respiratory flow rate of a patient. The dead space commonly encountered in prior art connectors is substantially reduced and the likelihood of disconnection is reduced or eliminated. The connector permits gas measurement adjacent the patient and at a cross sectional flow are that approximate the inner diameter of the endotracheal tube.
