PEAK-FLOW METER
Valid Article
PEAK FLOW METER, manual
Definition
A manual, hand-held instrument designed to measure only the maximum rate of expiratory gas flow from the lungs. It includes a tube for patient exhalation, easy-to-grip, and a calibrated scale that shows the value of the peak flow.
The device helps to discriminate the pulmonary status in routine tests performed in or outside of a clinical setting; it is also intended for periodic self-evaluation of the respiratory status of a patient, and to help in the treatment evaluation of patients suffering from chronic respiratory disorders (e.g., asthma, emphysema).

- Blow as hard and fast as possible (blowing a long time doesn't help)
- Repeat this attempt 2 times and write down the highest reading
- Dispose of the cardboard mouthpiece after use
Keep a sufficient stock of cardboard mouthpieces (see related articles below)
Maintenance
The plastic mouthpiece can be autoclaved.
The peak flow meter is not autoclavable and must be cleaned and disinfected with a detergent/disinfectant solution for surfaces / non-invasive medical equipment. Prepare use-solution in concentration required. Always read the label and product information before use. Do not mix with other products. Make sure to wet the surfaces completely, use a wipe or towel, keep them wet for the whole exposure time.
Shake well to ensure any trapped air is expelled. Rinse and let dry naturally.
