In acute care unit, airborne cross-infection is prevented partly by supplying fresh air to a room by mechanical ventilation. Therefore, central air vents is necessary. On the other hand, when the fresh air communicates with the polluted air continuously, bacteria disseminates widely throughout the ward. It is even reported that poorly maintained ventilation systems may eventually act as a source of, rather than as a defense against, aerosol/airborne infection. However, i personally have no experience finding the risk of peritonitis in this environment is higher than at home, neither dose any published data show this evidence.
Therefore, i think this is a very interesting point to compare the air sample in ventilated room and enclosed room. To further explore the most appropriate ventilation method for dialysis exchange in acute care unit might be needed. You can find more interesting data on one review published on J. R. Soc. Interface 2009; 6: s697-s7-2.
From our experiences, some factors including hand hygiene, wearing mask(Dong et al 2009 PDI), surface and air disinfection should be paid more attention during dialysis exchange. The movements of people inside this room should be reduced as less as they can.
