收缩压和舒张压（bp）是疾病诊断的重要生理参数。收缩期和舒张期特征比由振荡脉冲波形得出，已被广泛应用于振荡血压测量装置中自动无创血压的估计。振荡脉冲波形很容易受到呼吸的影响，这可能导致特征比和随后的BP测量的变化。本研究定量研究了呼吸模式（即正常呼吸和深呼吸）如何影响收缩期和舒张期特征比。该研究收集了39名健康受试者的临床数据，每位受试者在正常呼吸和深呼吸时都进行了血压测量。分析结果显示，正常呼吸下收缩期特征比由0.52±0.13显著升高至深呼吸下的0.58±0.14 (p < 0.05)，而正常呼吸下的0.75±0.12至深呼吸下的0.76±0.13对舒张期特征比无显著影响（p = 0.48）。综上所述，深呼吸对收缩期特征比有显著影响，提示静息状态下经过验证的自动测BP仪应严格使用静息状态下的测量。
Systolic and diastolic blood pressures (BPs) are important physiological parameters for disease diagnosis. Systolic and diastolic characteristic ratios derived from oscillometric pulse waveform have been widely used to estimate automated non-invasive BPs in oscillometric BP measurement devices. The oscillometric pulse waveform is easily influenced by respiration, which may cause variability to the characteristic ratios and subsequently BP measurement. This study quantitatively investigated how respiration patterns (i.e., normal breathing and deep breathing) affect the systolic and diastolic characteristic ratios. The study was performed with clinical data collected from 39 healthy subjects, and each subject conducted BP measurements during normal and deep breathings. Analytical results showed that the systolic characteristic ratio increased significantly from 0.52 ± 0.13 under normal breathing to 0.58 ± 0.14under deep breathing (p <; 0.05), and the diastolic characteristic ratio was not significantly affected from 0.75 ± 0.12 under normal breathing to 0.76 ± 0.13 under deep breathing (p = 0.48). In conclusion, deep breathing significantly affected the systolic characteristic ratio, suggesting that automated oscillometric BP device which is validated under resting condition should be strictly used for measurements under resting condition.
