What 4 factors are involved to allow the lungs the ability to exchange gas molecules?How are pulmonary functions test able to provide information about these 4 factorsWhat are the basic diagnostic and therapeutic questions that pulmonary function tests can answer?What are the components (besides PFTs) that make up a complete pulmonary assessment of the patient?In your own words describe the general purpose of PFTs.List the specific Indication for PFTsDescribe the difference between airway resistance (Raw) and restrictive lung impairment.List the physiologic factors (not diseases) that can obstruct air flowList the physiologic factors (not diseases) that can decrease the ability of the lungs to inflateWhat are the two major pathological processes that are identified by PFTs?What are the two specific components of lung mechanics measurements?Based on the AARC clinical guidelines, p. 405 Egan’s – identify the indications, contraindications and hazards/complications of PFT testing.How is the patient monitored (for safety and test accuracy) during a PFT maneuver? Describe the MVV testList the two most common tests that are used to monitor neuromuscular disease patient’s pulmonary function on a daily basis.Based on the AARC clinical guidelines, p. 416 Egan’s – identify the contraindications, hazards & complications and monitoring of a patient undergoing a Methacholine Challenge test.
