Assignee:

Respironics, Inc. - Murrysville PA

International Classification:

A62B 18/02

US Classification:

12820621, 12820312, 12820422, 12820511, 12820524, 12820628, 600532, 600538

Abstract:

A face mask including a gas monitoring capability for improved patient management in combination with improved efficiency of supplemental oxygen delivery to the patient is provided. The face mask of the present invention is configured to direct substantially all of the inspiratory and expiratory gas streams to and from the patient through a gas measuring device and to efficiently deliver supplemental oxygen. As such, the face mask permits measurement of both oral and nasal gas exchange.

US Classification:

600532, 600538, 73 233, 422 84

Abstract:

An integrated airway adapter capable of monitoring any combination of respiratory flow, Oconcentration, and concentrations of one or more of CO, NO, and an anesthetic agent in real time, breath by breath. Respiratory flow may be monitored with differential pressure flow meters under diverse inlet conditions through improved sensor configurations which minimize phase lag and dead space within the airway. Molecular oxygen concentration may be monitored by way of luminescence quenching techniques. Infrared absorption techniques may be used to monitor one or more of CO, NO, and anesthetic agents.

Abstract:

A system for measuring a metabolic parameter. The system includes an integrated airway adapter capable of monitoring any combination of respiratory flow, Oconcentration, and concentrations of one or more of CO, NO, and an anesthetic agent in real time, breath by breath. Respiratory flow may be monitored with differential pressure flow meters under diverse inlet conditions through improved sensor configurations which minimize phase lag and dead space within the airway. Molecular oxygen concentration may be monitored by way of luminescence quenching techniques. Infrared absorption techniques may be used to monitor one or more of CO, NO, and anesthetic agents.
