SUMMARY BACKGROUND AND OBJECTIVES:The number of patients requiring prolonged time on mechanical ventilation is increasing considerably in the intensive care unit (ICU). The objective of this study was to characterize the variability of methods and criteria used by physiotherapists to obtain weaning parameters in hospitals of Fortaleza. METHODS: After approval by the UNIFOR Ethics Committee, survey questionnaires were distributed among physiotherapists working in the ICU of three public and three private hospitals. Forty-four physiotherapists answered thirty-two multiple choice questions anonymously.
RESULTS:The main results concerned parameters commonly evaluated by physiotherapists. A significant difference between hospitals was found regarding the rapid shallow breathing index and maximum inspiratory pressure, which are more often used in private hospitals, with a percentage of 100% and 89.5%, respectively.
