상기 설정된 최대압박강도를 기반으로 상기 압박장치를 제어하여 상기 외부역박동을 수행하는 단계를 포함하고,
상기 시험압박을 통해 설정된 상기 최대압박강도를 기반으로 상기 생체신호 중 심전도와 혈류량의 분석을 통해 상기 외부역박동을 위한 압박 및 압박해제 타이밍제어신호를 계산하며, 그 계산된 타이밍제어신호에 의해 상기 압박장치를 제어하며,
상기 타이밍제어신호는 상기 심전도와 혈류량 분석을 토대로 심장이완기의 정해진 시점에서 대동맥압이 정해진 레벨까지 증가되고, 심장수축기의 정해진 시점에서 대동맥압이 정해진 레벨까지 감소되도록 계산되고,
상기 맞춤형 최대압박강도를 설정하는 단계는,
상기 시험주기로 상기 시험강도를 점진적으로 증가시키면서 상기 시험압박을 수행하는 단계; 및
상기 증가된 시험강도에 의한 압박이 피시술자의 수용 가능한 범위인 압박수용범위를 초과한 것으로 판단한 경우 상기 증가된 시험강도를 기초로 상기 최대압박강도를 설정하는 단계를 포함하며,
상기 시험강도의 초기값을 0.095 ~ 0.122 kgf/cm2의 범위내에서 설정하고, 상기 시험강도의 최대 제한값을 0.3 ~ 0.5 kgf/cm2의 범위내에서 설정하는 외부역박동시스템의 제어방법. - 삭제
