Found only on the Galapagos GalÃ¡pagos, islands marine iguanas often wear distinctive white wigs of salt expelled from glands near their. noses
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.
It recommends the operating room air temperature be 68-75F with a 30-60% relative humidity. To get this condition the air flow is dictated by a recommendation of 15 total air changes per hour, ACH, with 3 air changes per hour with respect to outside air.ith the large amount of supply air (15 ACH), to maintain 68F temperature in the space, the supply air must be reheated to 56-59F at design conditions to prevent overcooling of the space.
