Page 5: Preparing The Device When Changing Patient
PreParing The DeviCe when Changing PaTienT Before using the ventilator on a different patient, clean and disinfect it to such an extent that it is free from any human pathogens. Please ensure that all tools used, such as measuring instruments and test lung, are free from human pathogens. If MRSA contamination is suspected, the device must be packaged, with the appropriate label- ing, and disinfected accordingly. If the accessories (e.g., tube system, mask, fi lter, humidifier, etc.) are intended for repeated use, the manufacturer's provisions must be followed. The reprocessing of the device acc. to procedure 1 and 2 must be documented. 3.1 REPROCESSIng PROCEDuRE 1 The following measures may only be carried out by companies with a QM system and appropriately qualified, authorized and experienced specialist personnel. To reprocess the device, carry out the following steps: •... -
