This article reports on a survey and analysis of ventilator alarm state in a children hospital. Based on the evaluation of the alarm effectiveness, we designed a survey statistical table for ventilator alarm investigation. We evaluated the alarm situation synthetically through investigation and statistical methods. Result shows that the current ventilator alarms are not sufficiently effective, 26.84% of them are meaningless alarms and those leading to clinician’s intervention make up only 2.26% of all the alarms generated. The reliability of statistical data was also analyzed. According to the survey results, we identified and analyzed the causes of the problem and proposed the corresponding alarm management methods.
