Abstract

The separate and combined effect of a ventilated mattress and acid-treated activated carbon fibre (ACF) fabric on reducing the exposure to body generated gaseous pollutants in hospital environment was studied. Full-scale experiments were performed in a climate chamber furnished as a single-bed hospital patient room at reduced background ventilation rare of 1.6 air changes per hour. The bed of the patient was equipped with the ventilated mattress (VM) having an exhaust opening from which bioeffluents generated from human body were sucked and discharged from the room. To enhance the pollutant removal, acid-treated activated carbon fibre material was used in some of the experiments in the form of patient’s cover. The simulated pollution source was ammonia gas released from the patient’s groins. The results show that when using the ventilated mattress the ammonia gas concentration in the room was significantly reduced compared to the concentration measured when the VM was not in operation. The concentration of ammonia gas in the room was 100% removed when the VM operating at 1.5 L/s and the ACF material used as a cover were used together.
