在临床研究之后，已经仔细选择了物理校准功能的间隔。因此，独立选择生理校准的间隔是不可取的。
The reason for the short intervals in the beginning of the measurement can be found in that during the first minute the increased pressure on the finger compresses the tissue. This causes the interstitial fluids to shift, which in turn has an effect on the signal quality. When the algorithm detects a stabilization of the signal quality, and it is adequate enough, the interval between calibrations is increased. When a stable measurement is ongoing, the interval will be 70 heart beats, which was found to be the maximum interval to be able to compensate for possible changes in finger artery compliance. During the measurement signal quality can change and intervals are adjusted up or downwards accordingly.
如果校准是干扰的措施ment, it can be stopped altogether. Please be aware that this may reduce long term tracking of blood pressure during the period the Physiocal calibration feature is not active. Hence turning off this feature for long periods is not recommended.
