My question comes from Organization of Theaters topic in chapter Anaesthesia of Clinical Science

Answer 1

Right choice is (d) Air is blown in from the upper part and sucked out from the lower part

For explanation: This kind of ventilation system should actually exist throughout the hospital. The air which passes through various filters is pumped in and the air in the room is pulled out from the lower regions. This forms a steady air current and fresh, treated air is constantly circulated. This reduces the chances of nosocomial infections and wound festering.
