The measurement is also called the peak expiratory flow rate (pefr) or the peak expiratory flow (pef) the measurement should be started after a full lung inhalation this is done to find your “personal best” peak flow measurement this value will be used as a baseline for your daily measurements. Lung function tests, what is pefr and how can we measure it, importance in pefr value in lung diseases have been included in this analytical essay lung function test measurements of respiratory function may provide valuable information. For each subject, control readings of heart rate, pulse pressure and peak expiratory flow rate (pefr) were taken at 3 minute intervals for 12 minutes at 12 minutes, two successive doses of the assigned inhaler were taken (2 x 01mg doses= 02mg), immediately after which the three variables were measured.

Database of free biology essays - we have thousands of free essays across a wide range of subject areas peak expiratory flow rate (pefr) in lung diseases pefr value means peak expiratory flow rate that is a persons maximum speed of expiration it can be measured by peak flow meter which is. Peak expiratory flow rate (pefr) is the simplest estimate for lung functions it indicates the severity of airflow limitation peak expiratory flow rate is measured by peak expiratory flow meter (pefm) which is a simple and relatively cheap device [ 8 . Lung map trials, what is pefr and how can we mensurate it, importance in pefr value in lung diseases have been included in this analytical essay lung function test measurements of respiratory map may supply valuable information.
The pefr test is a common test that helps to diagnose and check lung problems, such as: asthma chronic obstructive pulmonary disease (copd) a transplanted lung that is not working properly you may also perform this test at home it will help to determine if lung disorder treatments are working to prevent symptoms from worsening.
Peak expiratory flow rate (pefr) is the maximum flow rate generated during a forceful exhalation, starting from full lung inflation  pefr primarily reflects large airway flow and depends on the voluntary effort and muscular strength of the patient. Peak expiratory flow rate (pefr) a peak flow meter is a simple, inexpensive device which measures the highest flow of air out of the lungs, from peak inspiration, in a fast single forced breath out this reflects airflow resistance, the elasticity of the supporting lung tissues and ease of breathing. Three zones of measurement are commonly used to interpret peak flow rates it is easy to relate the three zones to the traffic light colors: green, yellow and red in general, a normal peak flow rate can vary as much as 20 percent.
It is revealed from this study that if the exposure duration is more than 15 years then the decrease in peak expiratory flow rate of lungs is 56% for labour, 60% for dresser and 65% for driller the decrease in peak expiratory flow rate in such percentage leads to many respiratory problems like wheezing, cough, silicosis etc. Pefr is the maximum rate at which the air can be expired after a deep inspiration measured using: wright peak flow meter or a mini peak flow meter useful: for assessing the respiratory diseases especially to differentiate the obstructive and restrictive diseases.
