Design outcomes
Primary
| Measure | Time frame |
|---|---|
| To calculate the correlation coefficient between the total hemoglobin index measured using finger-mounted tissue oximetry at the thenar muscle and blood hemoglobin levels during puerperium. | — |
Secondary
| Measure | Time frame |
|---|---|
| To calculate the correlation coefficient between the total hemoglobin index measured using finger-mounted tissue oximetry at deltoid and sternocleidomastoid muscles and blood hemoglobin levels during puerperium. As an exploratory research, to investigate intra- and inter-rater reliabilities, a time-dependent change in values at the same objectives, and the association between tissue oxygen saturation and blood hemoglobin levels. | — |
