4.1 Routine anesthesia set up preparation 

Equipment should be checked thoroughly each day and an abbreviated check of all equipment shall be completed before each anesthetic. The incorporation of a system check into the daily routine of setting up for surgery can help early detection of equipment problems and potentially avoid emergencies during anesthesia. Failure to check anesthesia equipment prior to use can lead to patient injury. Checking equipment has also been associated with a decreased risk of severe postoperative morbidity and mortality. The anesthetist should perform the following on daily base 

Check room temperature and humidity: Humidity and temperature levels are adjusted in accordance with relevant standards and clinical procedure. The temperature and the humidity play a very important role in maintaining staff and patient comfort. In low humidity there is a danger of the production of electrostatic sparks. The temperature in the operating theatre and anesthetic room should be sufficiently high to minimize the risk of inducing hypothermia in the patient, but must be comfortable for theatre staff. The patient may develop hypothermia at an ambient temperature of less than 21°C. Temperatures of 24°C are usually acceptable in the operating room, with a relative humidity of 50-60%; a higher environmental temperature is required during surgery in the neonate or infant. 

The overhead operating room lights should design to provide a range of intensity. They should be freely movable, shadow less and less heat emitting and easy to adjust. A high level of illumination is required over the operating table, and ceiling-mounted lamps are standard; it is preferable if they can be positioned directly by the surgeon. The intensity and color temperature of general lighting are very important to the anesthetist, as appreciation of skin color is affected by the spectrum of the source of illumination. The spectrum provided by lighting tubes should be similar to that of day light. A spot light should be available if increased illumination is required for specific procedures.
