Clinical Investigations in Critical CareVariations in the Measurement of Weaning Parameters: A Survey of Respiratory Therapists
Section snippets
Materials and Methods
A self-administered four-page, 32-item questionnaire was developed and piloted among respiratory therapists at our institution (see Appendix). The items specifically addressed the methods by which weaning parameters were obtained, and were based on published descriptions of the techniques incorporating input from the therapists. The questionnaires were anonymous and required about 10 min to complete. Some questions allowed multiple responses, and each response was tabulated for analysis.

Results
Of a total of 166 questionnaires distributed, 102 questionnaires (61%) were completed and returned for analysis. The majority of respondents (75%) report > 5 years of experience, and over half are certified respiratory therapists. Of the 102 respondents, 46 persons (45%) work in teaching institutions. Ventilator management is primarily directed by specialty internists (pulmonary/critical care) [41%], but the therapists also receive directions from others (general internists, surgeons, specialty
Discussion
Despite several decades of use, the constellation of bedside measures collectively referred to as “weaning parameters” have never quite met expectations. Witness the large number of variables that are considered weaning parameters and the continued search for bedside measurements that more accurately predict successful discontinuation of mechanical ventilation.1,2,3,4,5,6,7,8,9,15 These physiologic markers may provide insight about a patient's ability to tolerate discontinuation of mechanical
