Importantly, 1-year risk of death was more than twofold higher (P < 0.001) in patients with a 24-week decline in FVC between 5% and 10%. The estimated MCID was 2-6%.

WebIt is widely believed that patients with GBS and MG who have severely impaired pulmonary function should be intubated pre-emptively. A commonly cited rule for GBS patients is the 20-30-40 Rule: intubation is indicated if the FVC falls below 20 ml/kg, the MIP is less than 30 cm water, or the MEP is less than 40 cm water.

It requires that the subject make a maximal inspiration to TLC, then make a maximal forced expiratory effort, leaving only the RV. In a normal subject, the FEV 1 /FVC is greater than 0.8; patients with obstructive lung disease, such as asthma or COPD, show a decreased FEV 1 /FVC.
WebThe Global Initiative for Chronic Obstructive Lung Disease (GOLD) criteria 5 defines chronic obstructive pulmonary disease (COPD) as a ratio of post-bronchodilator forced expiratory volume in the first second to forced vital capacity (FEV 1 /FVC) of <0.7, which is in agreement with both the American Thoracic Society (ATS) and the European ...

The computer in the PFT machine will flag the FEV1/FVC as being too low based on whatever age is entered in the patient demographics.
