Description
- Peak Flow meter for the measurement of the patient’s ability to breathe out air – also called a spirometer.
- The peak expiratory flow, also called peak expiratory flow rate, is a person’s maximum speed of expiration, as measured with a peak flow meter, a small, hand-held device used to monitor a person’s ability to breathe out air. It measures the airflow through the bronchi and thus the degree of obstruction in the airways.
Here’s how to use the peak flow meter
- Return the cursor to zero.
- Inhale as deeply as possible through your mouth.
- Place your mouth around the mouthpiece of the device, pressing your lips together to avoid leaks.
- Exhale as hard and fast as possible.
- Note the position of the cursor on the scale.
- Repeat these operations three times to ensure measurement consistency.
- Keep the highest measurement as the EPD value.
The Peak Flow Meter also features a color scale alongside its graduated scale. Three zones have been defined:
- Green: controlled asthma
- Yellow: uncontrolled asthma
- Red: emergency
