Abstract

To protect the patient’s internal organs when a patient with cardiovascular disease occurs, it is important to reduce the elapsed time by providing emergency medical services. Decisions for conducting cardiopulmonary resuscitation are mainly made using the carotid palpation method, which directs the pulse of the carotid artery, which can diagnose the patient's condition according to one's own subject and cause cerebral blood flow to be blocked by excessive pressure in the carotid due to the weaken cardiopulmonary function. In this study, we developed a multimodal patch-type probe based on multi-channel ultrasound Doppler pairs and oxygen saturation measurement modules which can monitor cardiopulmonary functions. From the in-vivo experiments, the developed probe can be utilized as a novel tool that can increase the survival rate of cardiovascular disease patients by objectively monitoring the cardiopulmonary function of the patient quantitatively and promptly in an emergency situation.

심혈관계 질환 환자가 발생 하였을 때, 환자의 뇌와 내부 장기를 보호하고 생존율을 높이기 위해서는 사건 발생 이후 신속하게 응급 의료 서비스를 제공하여 경과 시간을 줄이는 것이 가장 중요하다. 뿐만 아니라 심폐소생술의 실시를 위한 판단은 경동맥의 맥을 직접 짚는 ‘경동맥 촉진법’은 실시자의 주관적인 판단과 약해진 심혈관 기능에 따른 뇌혈류 차단을 할 수 있다. 본 연구는 개발된 다중 초음파 도플러 채널 쌍과 산소포화도 측정 모듈이 결합된 패치형 프로브를 이용하여 경동맥의 혈류 속도, 맥박, 산소포화도를 생체 내 실험을 통해 정성적으로 측정하였다. 따라서 본 시스템은 응급 상황에서 정량적이고 신속하게 환자의 심폐 기능을 모니터링 하여 심폐소생술 판단 여부를 객관적으로 제공하여 응급 상황 시 심혈관계 질환 환자의 생존률을 높일 수 있는 차세대 진단 기기로 활용 될 수 있다.
