- Abstract: Objective To explore the application effect of parameter settings of ventilator tidal volume and high pressure alarm value in cardiopulmonary resuscitation (CPR). Methods A total of 94 patients undergoing CPR due to cardiac arrest were enrolled as the research subjects. According to different parameter settings of ventilator tidal volume and high pressure alarm value, they were randomly divided into observation group (6-7 mL/kg, 60 cmH2O) and control group (8-12 mL/kg, 40 cmH2O), with 47 cases in each group. The success rate of CPR, levels of lactic acid and arterial blood gas indexes ［pH, oxygen saturation (SaO2), partial pressure of blood oxygen (PaO2), partial pressure of carbon dioxide (PaCO2), bicarbonate (HCO3-)］ during treatment, peak inspiratory pressure (PIP) after treatment, scores of neurological function immediately after resuscitation and at 24 h after resuscitation were compared between two groups. Results The success rate of CPR in observation group was significantly higher than that in control group (65.96% vs 42.55%) ([χ2]=5.187, P=0.023). At 10 min and 30 min after CPR, the pH value, PaO2, PaCO2 and level of lactic acid in observation group were significantly lower than those in control group (P<0.05), while SaO2 and HCO3- were significantly higher than those in control group (P<0.05). After CPR, the PIP and resuscitation time in observation group were significantly lower than those in control group (P<0.05). At 24 h after resuscitation, the score increases of Glasgow coma scale and acute physiology and chronic health evaluation-II in observation group were significantly faster than those in control group (P<0.05). Conclusion The low tidal volume and up-regulating high pressure alarm value in ventilator can effectively improve arterial blood gas indexes in cardiac arrest patients, increase success rate of CPR and alleviate neurological injury, without increasing complications risk after CPR.
