Medical device adaptive control for hostile environment
A medical device is configured to monitor, using one or more sensors, an environmental condition of a physical environment proximate to a medical device, and to determine when a value representative of the environmental condition exceeds a threshold for safe operation of the medical device with regard to care of a patient. Responsive to the value exceeding the threshold, an operation mode of the medical device is automatically switched from a first mode currently programmed for the care of the patient to a second mode, the second mode using different parameters than the first mode to control the medical device.
