
Cleaning and disinfecting
The goal of infection control is to prevent the transmission of infection to patients/subjects and staff during pulmonary function testing.
Cleaning and disinfecting instructions should be strictly followed to control infections and assure the safety of the patient. Aspiration of residue,
particles and/or contaminated agents could be life threatening.
The recommendations in the following section are retrieved from Miller MR, Crapo R, Hankinson J, et al.: General considerations for lung function
testing. Eur Respir J 2005; 26:153–162.

Prevention of infection transmission
Transmission to technicians
Prevention of infection transmission to technicians exposed to contaminated spirometer surfaces can be accomplished through proper hand
washing and use of barrier devices, such as suitable gloves. To avoid technician exposure and cross-contamination, hands should be washed
immediately after direct handling of mouthpieces, tubing, breathing valves or interior spirometer surfaces. Gloves should be worn when handling
potentially contaminated equipment if the technician has any open cuts or sores on his/her hands. Hands should always be washed between
patients.
Cross-contamination
To avoid cross-contamination, reusable mouthpieces, breathing tubes, valves and manifolds should be disinfected regularly. Mouthpieces, nose
clips and any other equipment that comes into direct contact with mucosal surfaces should be disinfected, or, if disposable, discarded after each
use.
Only the portion of the circuit through which rebreathing occurs must be decontaminated between patients, or, if disposable, discarded after each
use. Disposable sensors, when appropriately used, avoid the need for decontamination of sensors and mouthpieces.
Tuberculosis
In settings where tubercolosis or other diseases that are spread by droplet nuclei are likely to be encountered, proper attention to environmental
engineering controls, such as ventilation, air filtration or ultraviolet decontamination of air, should be used to prevent disease transmission.
Haemoptysis and oral lesions
Special precautions should be taken when testing patients with haemoptysis, open sores on the oral mucosa or bleeding gums. Tubing and
breathing valves should be decontaminated before reuse, and internal spirometer surfaces should be decontaminated with accepted disinfectants
for blood-transmissible agents.
Other known transmissible infectious diseases
Extra precautions should be taken for patients with known transmissible infectious diseases. Possible precautions include the following: 1)
reserving equipment for the sole purpose of testing infected patients; 2) testing such patients at the end of the day to allow time for spirometer
disassembly and disinfection; and 3) testing patients in their own rooms with adequate ventilation and appropriate protection for the technician.
Disposable in-line filters
These may be an effective and less expensive method of preventing equipment contamination.
The use of in-line filters does not eliminate the need for regular cleaning and decontamination of lung function equipment.

Other precautions and warnings
Please take the following precautions during the cleaning and disinfection activities:
1.
The responsibility for handling, cleaning and decontaminating reusable medical devices should be assigned to trained, qualified individuals.
2. Appropriate protective clothing (gloves, masks, eye protection, gowns) will minimize the potential for personal exposure to blood borne and
other disease-producing organisms.
3. Immediately separate and contain soiled reusable devices at the point of use and transport to the decontamination area so as to minimize risk
of personal contact with contaminants.
4. A disinfectant solution is only effective if it can contact all surfaces of the items to be disinfected or sterilized.
