The following video clips establish two facts: 1. Ultra-clean ventilation, while extremely important, can be easily disrupted. 2. Waste heat from forced-air blowers not only destroys laminar flow, it dumps air from the floor into the surgical field.
Did you ever wonder where the waste air from the forced air warming goes?
Knowing that heat rises, did you realize that a forced air blower releases 900 watts of waste heat under the surgical table?
If you're a surgeon, did you ever wonder why you are sweating whenever forced air warming is used-- while everyone else in the room is freezing?
In the next 8 minutes, you'll see a series of experiments revealing the impact of waste heat in surgery.
