A chart called a 'nomogram' can be used to estimate your predicted peak flow if you are male or female, your age and height. It is important to remember that.
Peak flow readings are higher when we are well, and lower when the airways are constricted. From changes in recorded values, we may determine lung.
Men can have peak flow values as low as 100 liters/minute less than the average value shown and still fall within the normal range. Women can have peak flow.
Peak flow is a simple measurement of how quickly you can blow air out of your lungs. Read about why and how it's measured.
Why does the patient's/client's peak flow need to be tested? Adults should achieve readings of 400 to 700 litres per minute, with men.
