Looks like you’ve clipped this slide to already. PFT (pulmonary function tests) can measure lung mechanics (spirometry and lung volumes) or the gas exchange/diffusion function of the respiratory system. These noninvasive tests—spirometry, the lung diffusion test, and lung plethysmography—are used to help diagnose lung diseases like COPD, as well as to determine how treatment is working and if such a condition is progressing. Clipping is a handy way to collect important slides you want to go back to later.

Preop assessment is rarely to tell surgeon not to operate, but to prepare for pulmonary complications such as pneumonia, prolonged mechanical ventilation, etc. Measure of gas exchange at alveolar-capillary membrane. 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. If there is a problem it will go on to affect all areas of the body.
