Abstract Objective To explore the characteristics and monitoring effect of blood flow ultrasonography in carotid artery during unarmed and mechanical cardiopulmonary resuscitation.Methods A total of 28 patients with cardiac arrest ad鄄mitted into our department of emergency from November 2015 to November 2016 were selected as research objects. They were evenly divided into unarmed cardiopulmonary resuscitation(CPR)group (n=14)and mechanical CPR group (n=14)in random.In the unarmed CPR group,unarmed chest compression for 30 minutes was used,while in the me鄄chanical CPR group,30-minute mechanical chest compression was adopted.The average of peak systolic velocity(PSV) in carotid artery and frequency of compression in each minute during the initial 5 minutes and the terminal 5 minutes were measured by Ultrasound Doppler technique.Results In the unarmed CPR group,the average PSV value in carotid artery during the initial 5 minutes was higher than that of the terminal 5 minutes with a statistical difference(P＜0.01). The achieved rate of compression frequency was also higher than that in the terminal 5 minutes(P＜0.05).In the me鄄chanical CPR group,the average PSV values in the initial 5 minutes,terminal 5 minutes,and achieved rate of compres鄄sion frequency were all higher than those in the unarmed CPR group with statistical differences(P＜0.01).The achieved rate of compression in the mechanical CPR was 100%.Conclusion Compared with unarmed CPR,the mechanical CPR can obtain a better carotid artery perfusion.Ultrasonography can realize the real-time feedback of compression frequen鄄cy and blood flow in carotid artery,and is used as a non-invasive CPR quality control.
