Vitalograph spirometer cleaning

This is the timetable for annual, monthly, daily, user test hygiene:

Every Test: A new mouthpiece should be used for each subject. A delay of at least 5 minutes should be allowed between subjects to allow settling of previously aerosolised particles in the measuring device.

Daily: Perform a visual inspection at the end of testing. If there is visible contamination to the flow head or the elsewhere on the device, clean and disinfect.

Weekly: Clean and disinfect all parts of the equipment which have come into contact with patients.

Monthly: The flow head screens or breathing tubes should be replaced regularly. The frequency of this is dependent on the Facilities' Risk Assessment, usage, and test environment, but should be at least monthly or every 100 subjects (500 blows). They should also be replaced in the event of damage, or if visibly contaminated.

Annually: Annual inspection, maintenance and calibration certification should be obtained from the manufacturer or a qualified service supplier. All these procedures are a part of the manufacturer's recommended PPM (Planned Preventive Maintenance) service procedure.
