Measuring hematocrit and estimating hemoglobin values with a non-invasive, optical blood monitoring system

摘要: An optical blood monitoring system with a ratiometric model determines hematocrit values for hemodialysis patient, from which hemoglobin the patient are estimated. The is calibrated, normally against cell counter, using bank. bank preserved in long term preservative typically different than that found clinical settings. value determined by scaled scaling factor so estimated level output monitor consistently matches measured setting. substantially about 1.033 when patient's sample stored short ethylene diamine tetra acetic, and 1.06 without being added to sample. can also be adjusted altitude.
