APPARATUS AND METHOD FOR MEASURING PHOTOPLETHYSMOGRAM |
| 摘要 |
Disclosed is an apparatus for measuring photoplethysmogram. The apparatus includes a ring structure with at least one photon source and at least one photon detector positioned on an inner surface of the ring structure. The apparatus further includes a controller configured to measure a preliminary photoplethysmogram during a first time period by taking a first number of samples, determine a form factor from said preliminary photoplethysmogram, determine an inter beat interval from said preliminary photoplethysmogram, and use the form factor and the inter beat interval to determine a second number of samples to be taken during a second time period of measurement of the photoplethysmogram and the distribution of the samples to be taken in function of time. |

1. An apparatus for measuring a photoplethysmogram, comprising:
a ring structure with at least one photon source and at least one photon detector positioned on an inner surface of the ring structure; and a controller configured to
measure a preliminary photoplethysmogram during a first time period by taking a first number of samples,determine a form factor from said preliminary photoplethysmogram,determine an inter beat interval from said preliminary photoplethysmogram, anduse the form factor and the inter beat interval to determine a second number of samples to be taken during a second time period of measurement of the photoplethysmogram and the distribution of the samples to be taken in function of time. |
