Peak Flow With Zone Indicators

Peak flow assists people with asthma by telling them that an asthma attack is likely to occur. If a person’s peak flow is low then the person’s asthma is bothering him or her and likely of an attack increases. This may be caused by triggers that increase the asthma symptoms such as pollen, cigarette smoke, or dust. A peak flow meter also help a person detect these triggers and steps can be made to remove the person from the triggers.

Monitoring Asthma Symptoms

Measuring peak flow is also often used to access if certain asthma medications are helping a person or not. If a person’s peak flow measurement is low then it may be a cue to change or increase medications to alleviate the asthma symptoms and prevent the likelihood of an asthma attack. If a peak flow is very high, then it may be possible to reduce the dosage of medications. No changes to medications should be made without the consultation of the doctor.
