Abstract
This study aimed to evaluate the effectiveness of simulation-based ventilator alarm management training on knowledge and practice among nurses. It was conducted among 50 nurses of neurosurgery department AIIMS, New Delhi. Assessment of knowledge and practice regarding ventilator alarm management was done using researcher-developed knowledge questionnaire and observational checklist. Didactic teaching of 15- 20 minutes was done regarding various ventilator alarms following the baseline assessment. Hence, simulationbased teaching on managing ventilator alarm was conducted in a group of 3-4 participants which consisted of pre-brief (3-5 min explanation regarding the situation the participant was to experience), scenario run (7-10 min where the response and measures of managing different ventilator alarms are performed) and debrief (15-20 min of discussing the positive and right performance of participants followed by different areas requiring improvement). A low tech manikin (half body Laerdal manikin) was used for the simulation and the simulation was conducted in neuro ward of AIIMS, New Delhi. The entire intervention lasts for 40-45 min after which immediate post-test was done for knowledge and skill. Retention of knowledge was assessed 7 days after the intervention. Nurse’s knowledge range regarding mechanical ventilator alarm management in pre-test was 11 (8, 15) MED (IQR), post-test 1 was 15 (13, 17) MED (IQR), post-test 2 range was 15 (13.16) MED (IQR). Thus, there was significant improvement in the knowledge level of nurses regarding the ventilator alarm management after the intervention (p <0.001). The pre-practice score of nurse’s skill in managing mechanical ventilator alarm management was 3.5 (2, 5) MED (IQR) and postpractice score minimum maximum range was 10.5 (2, 14) MED (IQR). There was significant improvement in the skill level of nurses regarding the ventilator alarm management after the intervention (p <0.01). Simulation-based education improves nurse’s knowledge and practice in recognising and managing the ventilator alarms.
