By referring Part XVI – Special Requirement for Critical Care Unit or Intensive Care Unit, Clause 221 (a-e) - Facilities and design features, stated that:-
a) adequate supply and distribution of oxygen and medical gas, suction, electricity, lighting and air conditioning with provision for emergency back-up in the event of failure or breakdown of supply;
b) Capability to separate or isolate infected patients or patients at particular risk of infection;
c) Readily accessible hand washing facilities to staff in the critical care unit or intensive care unit and in each patient room;
d) Adequate facilities for appropriate diagnostic , monitoring, therapeutic intervention and life support facilities; and
e) Adequate equipment and monitors for the transport of patients.
Remark:
According to above statements, the law does not state any temperature requirement in an ICU. Through the committees’ discussion, HTS proposed that the ICU temperature shall be 20 to 22 degree Celsius.
The twelve air change term has been proposed recently by the HTS technical committees’ as six out of twelve air change shall be contained fresh air and recycle air for the excess proportion in ICU.
Notes: Please do refer to Table 3 : General Pressure Relationship and Ventilation of Certain Hospital Areas for further information.
According to ASHRAE Handbook 2005, Air Change Effectiveness is a description of an air distribution system’s ability to deliver ventilation air to a building, zone, or space.
One common definition of air change effectiveness is the ratio of a time constant to an age of air.
The age of air is the length of time that some quantity of outside air has been in a building, zone, or space. The “youngest” air is the point where outside air enters the building by forced or natural ventilation or through infiltration.
We are looking forward to any comments or suggestion beyond this topic to enhance our expertise and improve the hospital technical comprehension. Your contributions are most welcome.
