Abstract: A clothing apparatus is provided with at least one fabric panel, a panel of stretch fabric, a sensor unit retaining pocket, and a light opaque fabric. The at least one fabric panel is configured to encompass a patient thoracic region. The stretch fabric panel is joined to the fabric panel about the thoracic region of a patient when wearing the clothing apparatus. A free edge of the overlapping stretch fabric panel is configured to be releasably mated along an overlapping area of the stretch fabric panel with one of the fabric panel and the stretch fabric panel. The sensor unit retaining pocket is provided between the at least one fabric panel and the stretch fabric panel. The light opaque fabric is provided in the fabric panel about an opening in an inner surface of the fabric panel contiguous with the retaining pocket. The opening is configured to enable a sensor unit received within the pocket to maintain direct contact with a skin surface of a patient over the thoracic heart region.

Abstract: The respirator system controls operation of an exhale gas pressure control valve and an delivery gas flow control valve interposed in tubes leading to the patient's airway. Each control valve is operated by a Venturi flow pilot valve having a variable exhaust flow which is a function of an electromagnetic linear actuator. Operation of the electromagnetic actuator is accurately controlled by computer hardware and software, which can operate the pilot valves to meet a wide range of ventilation modes for patients of any size or physical condition.
