측정 자세의 변화에 따른 맥의 변화 특성: 선 자세, 앉은 자세, 누운 자세 = Properties of Pulse Waveforms by Posture Changes: Standing, Sitting, Supine Posture

다국어 초록 (Multilingual Abstract)

Objectives: Informations on pulse diagnosis in literature are based on diagnosing pulse waveforms on supine posture. However, today`s pulse waveforms are measured on various postures for the convenience of patients or doctors. For objective measurement, the effect of posture on the pulse waveforms should be considered. The objective of this study was to find posture-related changes in the radial pulse waveforms. Methods: We used an instrument, DMP-3000(DAEYOMEDI Co., Ansan, Korea), measuring radial pulse waveforms noninvasively by tonometric method. 25 male subjects participated in the trial. Before measuring radial pulse waveforms subjects had rest for 5 min. The pulse waveforms were measured on the left wrist. Each subject underwent this course on the supine, sitting, and standing posture. We analyzed pulse waveforms with Height-parameters, Time-parameters, Energy, and Elastic rate. Results: Height-parameters(h1~h5) on the supine posture were bigger than those on the sitting and standing posture. In case of Time-parameters, the parameters making up systolic time decrease in order of on standing, sitting, and supine position. However, systolic time and diastolic time didn`t have any changes. Energy of pulse was the biggest on supine posture and Elastic rate on standing posture. Conclusions: In this study we found that posture changes affect radial pulse waveforms. For quantification of the changes, more trials should be done. After analyzing much data we might apply parameters of pulse waveforms changed by posture. Also, we might diagnose special disease with properties of pulse waveforms by posture.
