Heart-Lung Machine GUI touchscreen may go dark for 10-15 seconds, safety/performance functions remain operational before reset, control maintained through backup control panel, but second reset may occur, may lead to gas blender standby, then gas blender must be reactivated using user interface on blender, sensors deactivated until new case started; GUI reset can lead to Hypoxia and Hypoperfusion.
The firm's labeling (Quick Reference Guide) contains incorrect information in the maintenance schedule for the Heater-Cooler device.
One ferrite ring expected to be installed on centrifugal pump system power cable may not be present.
The SCP control Panel rotary knob used to control rotary speed of the pump in the SCP system used as a centrifugal pump during cardiopulmonary bypass may be difficult or impossible to rotate as a result of premature wear of the angle encoder. The loss of function of the angle encoder during bypass may lead to ischemia, stroke, organ damage, arterial tissue injury or reperfusion syndrome.
