Despite the clinical relevance of cuff pressure in ventilated patients,it is not routinely measured by health care workers. Lack of knowledge could be a contributing factor. The aim of this study is to assess the knowledge of cuff pressure among health care workers at our institution.
A written survey was conducted among medical residents, critical care nurses and respiratory therapists in a tertiary care hospital. Respondents were deemed to have adequate knowledge if they answered the cuff pressure question correctly which is 18–25 cm H2O normally. The respondents who failed the initial test were educated and then reevaluated. Fisher's Exact Test was used to determine significant differences between groups.
Twenty-five critical care nurses, 25 respiratory therapists and 50 medical residents completed the survey. A significantly greater percentage of respiratory therapists answered the survey correctly compared to critical care nurses (84% versus 20%; p < 0.001) and medical residents (84% versus 28%; p < 0.001). We observed no statistically significant difference between the proportion of medical residents who answered the questions correctly compared to critical care nurses (28% versus 20%; p = 0.63). Adherence improved in our hospital after the study.
Cuff Pressure measurement should be included in the daily care plan. Our study supports the need to educate health care workers taking care of ventilator patients and thus prevent complications.
Cuff pressure monitoring helps to prevent complications such as mucosal ulcerations, tracheomalacia, tracheobronchial fistula and ischemic tracheal injury leading to tracheal stenosis.
