An approach for scheduling clinical procedures based on defined environmental thresholds of medical units in healthcare facilities. In one embodiment, a computer system monitors environmental conditions of the medical unit in which clinical procedures will be performed utilizing a measurement system that includes an environmental device for monitoring the environmental conditions. The computer system further receives a schedule of the clinical procedures of the medical unit. The computer system further identifies environmental thresholds for the medical unit to be used for comparison against the environmental conditions of the medical unit. The computer system further compares environmental conditions to the environmental threshold to determine if the environmental thresholds are violated. In another embodiment, the computer system modifies the schedule of clinical procedures of the medical unit responsive to the determination.
