I work in Asheville, NC and we try to extubate our OH patients within 4 hours. We have a rapid wean protocol and if they meet the criteria they are extubated. About 75 to 80% meet this criteria. They do pretty well. Our respiratory therapist does the extubation with the nurses assistance. We start IS within 2 hours and if unable to do half of preop value EZ PAP is started and aggressive cough and deep breathing is initiated.
Hope this helps.
