I also want to follow your peak expiratory flow rate carefully.

(The peak expiratory flow rate measures how fast a person can exhale).

Learn about the purpose of Peak Expiratory Flow Rate, what to expect and how to prepare for this test.

Measurement of airflow, such as peak expiratory flow rates, which can be done inexpensively on the track or sideline, may prove helpful.

The highest of three readings is used as the recorded value of the Peak Expiratory Flow Rate.

FEV 1, FVC, and peak expiratory flow rate were measured during the hospital stay.

The presence of expiratory phase wheezing signifies that the patient's peak expiratory flow rate is less than 50% of normal.

Indirect Assessment of Peak Expiratory Flow Rate in Healthy Indian Children.

It is clinically classified according to the frequency of symptoms, forced expiratory volume in one second (FEV1), and peak expiratory flow rate.

In this case, the individual's Peak Expiratory Flow Rate (PEFR) is measured.

There are two subtypes divided by symptoms: Type 1 and Type 2, depending on the stability of the patient's maximum speed of expiration, or peak expiratory flow rate (PEFR).

Peak Expiratory Flow Rate Test Peak Expiratory Flow Rate information at HowStuffWorks.

Asthmatic subjects in 9 to 11 years old, 80% to 85% of asthma exacerbations that were associated with reduced peak expiratory flow rates and wheezing were due to viral upper respiratory tract infections (URIs).

The peak expiratory flow (PEF), also called peak expiratory flow rate (PEFR) 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.

For a diagnosis of PMA to be made it is necessary to have a detailed history of the timing of menstrual cycles along with asthma symptoms experienced, and the peak expiratory flow rate (PMA may cause the PEF to be lowered in the premenstrual period).

Other supportive evidence includes: a 20% difference in peak expiratory flow rate on at least three days in a week for at least two weeks, a 20% improvement of peak flow following treatment with either salbutamol, inhaled corticosteroids or prednisone, or a 20% decrease in peak flow following exposure to a trigger.
