All-digital, tempered glass and metal body plethysmograph features fail-safe automatic release of the cabin door locking mechanism, patient intercom, and motorized sensor arm, providing superior performance, patient comfort and convienence.
A graphic recorder designed for determining and registering airway resistance and thoracic gas volume to assess pulmonary function. It includes an airtight body chamber and transducers that allow the recording of chamber pressure versus airflow, and chamber pressure versus mouth pressure, to determine the airway resistance. Thoracic gas volume is typically determined by recording the chamber and airway pressures simultaneously with the airway open and with the airway occluded. It may also be possible to determine the instantaneous flow by recording the pulmonary capillary blood flow with the device.
