AIR CONDITIONING HOSPITAL REQUIREMENTS

• Hospital Air Conditioning assumes a more important role

than just comfort. • These days proper AC is a factor in patient therapy. In some cases is the major treatment • Controlled environment provide more rapid physical improvement than those patients with no air conditioning. • Patients with Thyrotoxicosis do not tolerate Hot, Humid Conditions or Heat Waves. • A Cool and Dry environment favors the loss of heat by radiation and skin evaporation and may save the life of a patient. • Cardiac patients may be unable to maintain the circulation necessary to ensure normal heat loss. Walter D. Gameiro, PhD Mec. Eng. 2

AIR CONDITIONING HOSPITAL REQUIREMENTS

• AIR CONDITIONING CARDIAC WARDS and CARDIAC ROOMS, especially those with congestive heart failure, is necessary and considered therapeutic. • AIR CONDITIONING for patients with HEAD INJURIES, subjected to BRAIN OPERATIONS and those with BARBITURATE POISONING may have HYPERTHERMIA, especially in a hot environment, due to a disturbance in the heat regulatory center of the brain. • THEREFORE, an important factor in recovery is an environment in which the patient can loose heat by radiation and evaporation, and that means :

• a COOL ROOM with DEHUMIDIFIED AIR.

AIR CONDITIONING HOSPITAL REQUIREMENTS

• Rheumatoid Arthritis patients react better to treatment in an environment of 90°F and 35% Relative Humidity. • Dry Conditions, in other cases, will be an hazard to the ill and debilitated by contributing to secondary infection or infection totally unrelated to the clinical condition that caused the hospitalization. • Clinical Areas devoted to upper respiratory disease treatment and cute care, as well as general clinical areas of the entire Hospital should be maintained at a Relative Humidity of 30 – 60%. • Chronic Pulmonary disease patients often have Respiratory Tract Secretions. As these secretions accumulate and increase in viscosity, the patient EXCHANGE of HEAT and WATER is REDUCED. Therefore, inspiration of WARM HUMIDIFIED air is essential to prevent DEHYDRATION. Walter D. Gameiro, PhD Mec. Eng. 4

AIR CONDITIONING HOSPITAL REQUIREMENTS

• Oxygen therapy Patients & those with Tracheotomies, require WARM HUMID inspired air. • Cold and Dry Oxygen or the bypassing of the nasopharyngeal mucosa presents an extreme situation. • Re-breathing techniques for Anesthesia and enclosure in an incubator are special means of addressing impaired HEAT LOSS in Therapeutic Environments. • Burn patients need a HOT ENVIRONMENT and HIGH RELATIVE HUMIDITY. • SEVERE BURN PATIENT WARD should have temperature controls allowing up to 90°F and 95% Relative Humidity. .

NEED TO RESTRICT AIR MOVEMENT IN AND BETWEEN THE VARIOUS DEPARMENTS. SPECIFIC REQUIREMENTS FOR VENTILATION AND FILTRATION TO DILUTE AND REMOVE CONTAMINANTS SUCH AS ODOR, AIRBORNE MICROORGANISMS, VIRUSES, also HAZARDOUS CHEMICALS, AND RADIOACTIVE SUBSTANCES. DIFFERENT TEMPERATURE AND HUMIDITY REQUIREMENTS FOR VARIOUS AREAS. DESIGN SOPHISTICATION NEEDED TO PERMIT ACCURATE COMPUTER CONTROL OF ENVIRONMENT IN ALL THE DIFFERENT AREAS
