BACKGROUND AND OBJECTIVES: Concerning the mechanical ventilation, the weaning is a usual and significant intensive care process. Identifying, describing and demonstrating the techniques used by Respiratory Therapists in weaning and also obtaining its parameters in Intensive Care Units (ICU). METHODS: A survey related to the weaning process was done with active ICU Respiratory Therapists from (FD) in the year 2005. The survey consisted of 31 subjective and objective questions, some of them allowing multiple answers. RESULTS: Eighty surveys were carried out at twenty hospitals. 90% of participants were specialized staff with a mean of three year working experience in ICU. In 98.7% of the answers, doctors and respiratory therapists were responsible for operating the ventilators. In 61.3%, doctors and respiratory therapists were responsible for their use and, in 36.3%, the responsibility was solely on the respiratory therapist professionals. It was found that only twenty-four respiratory therapists (30%) follow the weaning protocol. Among the most practiced parameters from the weaning process are: respiratory frequency (98%), tidal volume (97.5%) and periferic oxygen saturation (92.5%). The least utilized are the maximum inspiratory pressure (18.8%) and the vital capacity (13.8%). CONCLUSIONS: Great differences were observed in the weaning methods, choice of parameters and the way they were collected. These variations suggest that there is a lack of routine and the need to implement simple protocols.

BACKGROUND AND OBJECTIVES: Weaning patients from mechanical ventilation is still a challenge in Intensive Care Units (ICU) and is related to complications and mortality. Daily rounds at the bedside, which are part of good care, can identify patients able to undergo to spontaneous breathing trials. The authors suggest one mnemonic technique with the term "ESTRATEGIA" (strategy) considering some key aspects, as a checklist, which can be applied by any person of the multidisciplinary team, during the bedside rounds, in order to shorten the weaning time. CONTENTS: To introduce the word Strategy as a mnemonic method based on the studies related to weaning from mechanical ventilation and its applicability as a checklist in any intensive care unit by the multidisciplinary team where each letter reminds some key aspects related to the subject. CONCLUSIONS: The applicability of a mnemonic mechanism as a checklist for weaning patients from mechanical ventilation easily practiced during the daily round to identify those who are able to undergo to spontaneous breathing trials.
