From changes in recorded values, we may determine lung functionality, severity of asthma symptoms, and treatment options. Equally important, your personal best is the measurement against which all your other peak flow measurements will be compared. Asthma, chronic obstructive pulmonary disorder, and emphysema are some of the conditions that will affect peak flow meter readings. It is important to use the same peak flow meter every time. Tech-savvy parents can also try to create an for tracking purposes. However, an individual's personal best must be established by using the same peak flow meter twice a day for two weeks.

Peak Flow Meter for Asthma

Peak flow meters are relatively inexpensive, especially if you purchase a plastic device with a spring system. Currently, the guidelines recommend that peak flow monitoring be done in the morning. From changes in recorded values, patients and doctors may determine lung functionality, the severity of asthma symptoms, and treatment. To interpret the significance of peak expiratory flow measurements, a comparison is made to reference normal, predicted values based on measurements taken from the general population. This chart can be used to read-off your Normal value.

Anything below 50% of the baseline reading is in the red peak flow zone. A limited number of medical facilities are equipped and capable of performing this type of study. Like a yellow traffic light, this is a warning and means that your airway is beginning to narrow, though you may not have any symptoms yet. However, the results also depend on many other factors, including chest restriction, motivation and muscular power. However, when you do three blows straight after each other, the readings should all be about the same. This can be used for a long time as a teenager grows into adulthood.

The information on this page is written and peer reviewed by qualified clinicians. On a compressed chart, it is easy to see when the peak flow falls below that person's usual range, and to recognise gradual rises or falls in peak flow. An additional use of peak flow meters is to measure peak flow variability. It measures the fastest rate of air airflow that you can blow out of your lungs. Results of a Peak Flow Meter Test A peak flow meter displays the result as a unit of volume per a unit of time.

Measuring your peak flow before and after exposure to a possible asthma trigger, such as something you're allergic to or a substance you're exposed to at work, may also show if anything in particular causes your symptoms. Doctors and health practitioners develop management plans based on the green-yellow-red zones. Peak flow readings are higher when we are well, and lower when the airways are constricted. For example, a 30 year old male that is 5'10'' tall should have a reading close to 622 liters per minute. Am J Respir Crit Care Med, Vol 159, pp. If you plan to test at work and at home, for example, you may consider buying two of the same exact devices. Your normal may be very different than the normal on a generic reference chart, which is why it's so important to know your personal best peak flow reading.

The peak flow meter consists of a tube that you blow into and a scale that indicates how much air was expelled from the lungs in a given period of time. Along with the tracking chart, you will need to use a peak flow reference chart to determine the ideal peak flow number. When the readings are between 50 and 80% of the baseline reading, they are categorized in the yellow peak flow zone. Any lung condition that decreases air flow will result in abnormal readings. This allows patients to self-monitor and pass information back to their doctor or nurse.

On a compressed chart, it is easy to see when the peak flow falls below that person's usual range, and to recognise gradual rises or falls in peak flow. Symptoms of respiratory distress are present, requiring immediate administration of a rescue inhaler. This could be a sign that you have , although other tests such as will often be needed to confirm the diagnosis. This slows the speed of air moving through the lungs. It measures the rate at which air is expelled from the lungs.

All three treatments were well tolerated. Peak flow measurement can show the amount and rate of air that can be forcefully breathed out of the lungs. It is very important to use the same type of chart every time so that measurements can be compared and patterns can be recognised. Development of this peak flow chart Standardisation of peak flow charts is important to avoid confusion for those entering the measurements, and to allow development of pattern recognition skills by clinicians and patients. For this reason, tables or charts are used to determine the normal value for a particular individual.
