Nowadays almost all operating rooms are equipped with air conditioning (AC units). Their main purpose is climatization, like ventilation, moisturizing, cooling and also the warming of the room in large buildings. In operating rooms they have an additional function in the prevention of infections, especially the avoidance of postoperative wound infections. This is achieved by special filtration systems and by the creation of specific air currents. Since hypothermia is known to be an unambiguous factor for the development of postoperative wound infections, patients are often actively warmed intraoperatively using warm air blankets (forced-air warming units). In such cases it is frequently discussed whether such warm air blankets affect the performance of AC units by changing the air currents or whether, in contrast, have exactly the opposite effect. However, it has been demonstrated in numerous studies that warm air blankets do not have any relevant effect on the functioning of AC units. Also there are no indications that their use increases the rate of postoperative wound infections. By preventing the patient from experiencing hypothermia, the rate of postoperative wound infections can even be decreased thereby.
如今，几乎所有手术室都配备了空调（AC机组）。其主要目的是调节气候，如通风、保湿、制冷以及在大型建筑中对房间进行加热。在手术室中，它们还有预防感染的额外功能，尤其是避免术后伤口感染。这是通过特殊的过滤系统和产生特定的气流来实现的。由于已知体温过低是术后伤口感染发生的一个明确因素，患者在手术中经常使用暖空气毯（强制空气加热装置）进行主动加温。在这种情况下，经常会讨论这种暖空气毯是否会通过改变气流影响空调机组的性能，或者相反，是否会产生完全相反的效果。然而，大量研究表明，暖空气毯对空调机组的运行没有任何相关影响。也没有迹象表明使用它们会增加术后伤口感染率。通过防止患者体温过低，甚至可以降低术后伤口感染率。
