Successful surgery depends on optimizing working conditions for medical professionals and patients. Temperatures in operating rooms are often colder than many indoor locations, but people may not know why. However, the temperature range can have a significant effect on patient health and safety. The American Society of Heating, Refrigeration, and Air-Conditioning Engineers recommends that operating room temperatures be kept between 66 to 68 degrees Fahrenheit, with a humidity percentage of 70.
A temperature of 18 Â°C indoors corresponds to an outside temperature of about 15.5 Â°C. If the air temperature outside is 1 Â°C below 15.5 Â°C, then heating is required to maintain a temperature of about 18 Â°C. If the outside temperature is 1 Â°C below the average temperature it is accounted as 1 degree-day. The sum of the degree days over periods such as a month or an entire heating season is used in calculating the amount of heating required for a building. Degree Days are also used to estimate air conditioning usage during the warm season.
