The primary purpose of pulmonary function testing is to identify the severity of pulmonary impairment. Answer = Interstitial lung disease. Pulmonary function tests (PFTs) objectively assess lung function. Pulmonary function tests, or PFTs, measure how well your lungs work. Also for screening: this includes all current and former smokers &gt;45yoa, known COPD or asthma pts, also those scheduled for thoracic or upper abdominal surgery. tern is present, full pulmonary function tests with diffusing capacity of the lung for carbon monoxide testing should be ordered to confirm restrictive lung disease and form a differential diagnosis. See more ideas about pulmonary function test, respiratory therapy, respiratory care. Determine whether a patient with an obstructive disease pattern has evidence of hyperinflation or air trapping. Lung Function Test Obstructive Disease Restrictive Disease Forced Vital Capacity(FVC)4800ml = IRV+TV+ERV Normal Or Lower Than Predicted Value Lower Than Predicted Value Forced Expiratory Volume (FEV) 50 – 60 ml/Kg Or 0.75 – 5.5 l Lower Normal Or Lower Forced Expiratory Flow 25 – 75 % Lower Normal Or Lower Peak Expiratory Flow (PEF) men:400–800 l/min. The major limitation of pulmonary function tests is in how they are interpreted Along with measurement of arterial blood gases, PFTs are used to evaluate how much a patient’s symptoms or known lung disease impairs daily activities and the tests are helpful in management, such as when to treat a patient and in what setting. Pulmonary function tests (PFTs) • Pulmonary function testing is a valuable tool for evaluating the respiratory system • comparing the measured values for pulmonary function tests obtained on a patient at any particular point with normal values derived from population studies.

IF restrictive pattern, you’re going to want to get DLCO b/c it tells you whether the restriction is due to parenchymal disease (which will change your management), or NM, pleural or CW disease. The Dterature on pulmonaryfunction testing insareoldo­ sis is critically reviewed. Ventilation- Air exchange btwn alveolar So you have restrictive disease by spirometry and lung volumes. During the physical exam, your doctor will use a stethoscope to listen carefully to your lungs while you breathe.

Remember that DLCO should be normal in chronic bronchitis because it affects the more proximal airways which is not where your gas exchange takes place.

Preop assessment is rarely to tell surgeon not to operate, but to prepare for pulmonary complications such as pneumonia, prolonged mechanical ventilation, etc. Pulmonary Function Testing The Basics of Interpretation - Title: Pulmonary Function Testing The Basics of Interpretation Author: Matthew Heath Hale Last modified by: Dear User!
