Abstract

This study aims to investigate statistical variations and relationships of blood pressure (BP), phtotplethysmography (PPG) and cardiovascular parameters on changes in local skin surface temperature (SST) during gradual cooling and heating. Results showed that local SST changes affected the Finometer BP, the PPG waveforms and total peripheral resistance, but not oscillometric BP, heart rate, stroke volume and cardiac output. Therefore, in order to reduce for the errors, temperatures should be controlled or compensated when components of the PPG waveform are used to evaluate cardiovascular status in temperature variation environments.

본 논문에서는 혈압과 광용적맥파, 국부피부온도변화에 따른 심혈관 파라메터의 통계적 변화와 관계에 대해 연구하였다. 국부피부온도변화는 Finometer의 혈압, 광용적맥파 그리고 총말초저항에 영향을 주었고 오실로메트릭 혈압, 심박수, 심박출량에는 영향을 주지 않는 결과를 얻었다. 그러므로 온도변화가 있는 환경에서 에러를 줄이기 위해 심혈관계의 상태를 광용적맥파로 평가하기위해서는 온도를 제어하거나 보상해 주어야 한다.
