The Effects of an Extubation Program using CALM criteria on the Success of Weaning from Mechanical Ventilation in Critically Ill Patients with Respiratory Failure

This quasi-experimental research aimed to study the effects of an extubating program using the CALM criteria on the success of weaning critically ill patients with respiratory failure from mechanical ventilation. The participants were 60 critically ill patients with respiratory failure who were divided into two groups: a control group (n=30), which received routine weaning, and the intervention group (n=30), which received the mechanical ventilator weaning protocol which consisted of 3 phases: 1) pre-weaning for extubation readiness assessment; 2) inter-weaning for continuing care during weaning; and 3) post-weaning. The research instruments included the CALM criteria program used to assess readiness before pre- and post-extubation care record forms. General data were analyzed using descriptive statistics. The number of days with endotracheal tubes was compared using Mann-Whitney U tests. The success of weaning from the ventilator was compared using Chi-square tests.
The results of the research found that the duration of ventilator use between the control and experimental groups was not statistically different at (p>.05). Comparing the success in weaning from the ventilator between the control and experimental groups, it was found that the group using CALM criteria had significantly higher weaning success than the control group at (p<.0001). Extubating patients using the program using CALM criteria can increase the success of weaning the patients from the ventilator. This program can be applied to patients with other diseases in similar contexts and used as a guideline for professional nurses who extubate patients.
