Rossmax Peak Flow Meter - Adult

Compact, lightweight, and highly portable, the Rossmax Adult Peak Flow Meter is an essential companion for those seeking to monitor their respiratory health. Its built-in flexible three-zone management system and easy-to-read numbers make tracking your peak expiratory flow rate (PEFR) effortless and reliable. With a measurement range of 60-800 L/min, the meter ensures accuracy and repeatability, making it an indispensable aid for asthma management.

Crafted for adult use, this peak flow meter is washable and designed for ultimate convenience. It adheres to EN ISO 23747:2009 compliance and boasts CE approval, assuring its quality and adherence to international standards. Incorporate it into your daily routine as part of your treatment plan, recording your peak flow measurements in your "peak flow diary" for informed decisions alongside your physician.

How to Use:

  1. Set the red indicator to the bottom of the scale.
  2. Stand up, take a deep breath, and place your mouth around the peak flow meter, holding it horizontally to form a tight seal with your lips.
  3. Exhale forcefully and rapidly. The number where the indicator stops reflects your peak measurement. Avoid coughing or spitting into the meter to ensure accurate readings.
  4. Repeat the steps two more times to obtain three readings. Record the highest reading in your daily record chart.
