Correlation Between Spirometry and Functional Independence in Adult Post-ICU Patients

The test will follow the norms of the American Thoracic Society and reference values relative to the Brazilian population. The tests will be performed by physical therapists using the One Flow FVC® portable spirometer (Clement Clarke, England) and met the criteria for acceptance and reproduction of manoeuvres

Will be used to evaluate the functional independence of patients containing eighteen items encompassing six dimensions. Each item can receive scores of one to seven, where one corresponds to total dependency and seven to full independence. Each dimension is analysed by the sum of the items that compose it and the total score is given by the sum of each dimension, being able to vary from 18: complete dependence; 19 to 60: greater dependence (assistance of up to 50% of tasks); 61 to 103: less dependency (assistance of up to 25% of tasks); and 104 to 126: independent.
