Success Kit / Spirometer



The LIFE Ascent Success Kit will include a Microlife Digital Peak Flow Meter (PEF) and Forced Expiratory Volume (FEV). This device measures your lung function.

Why It Matters

The device measures Peak Expiratory Flow (PEF), or the speed at which you’re able to push air out of your lungs, and Forced Expiratory Volume (FEV), or how much air you can exhale during a forced breath. This spirometer can be used for rapidly determining whether there is an obstruction in your airway and it’s commonly used for diagnosing and treating asthma and chronic obstructive pulmonary disease (COPD).

How to Use the Spirometer

  • Step 1: To use, stand up, hold the device with both hands, and take a deep breath. Blow into the mouthpiece as fast and as hard as you can for as long as you can.
  • Step 2: During the exhale, bend forward to push all the air out of your lungs. The green, yellow and red bars on the display are quick indicators of the state of your lungs.
  • Step 3: Green indicates normal lung function, while yellow indicates mild obstruction. In that case, your doctor might prescribe a short-acting beta agonist or an inhaled corticosteroid. A red light might indicate a severe obstruction of the airways, and you should seek emergency care.
  • Step 4: Measure your peak flow rate twice daily and close to the same time each day. You can take your measurements multiple times. The device automatically stores your highest reading per session.
