The effect of blood hematocrit (HCT) on a noninvasive flow estimation algorithm was examined in a centrifugal implantable rotary blood pump (iRBP) used for ventricular assistance. An average flow estimator, based on three parameters, input electrical power, pump speed, and HCT, was developed. Data were collected in a mock loop under steady flow conditions for a variety of pump operating points ...

recombinant human erythropoietin (rh-epo) is known to accelerate erythropoiesis in preterm infants. the purpose of this study was to compare the effectiveness of early treatment with two doses of rh-epo (high vs. low dose) in the management of anemia of prematurity. twenty preterm infants with hematocrit (hct) < 30% when infant’s age was between 2 to 3 weeks after birth or hct <25% when infant’...

INTRODUCTION There are a number of pre-analytical and analytical factors, which cause false results in the complete blood count. The present case identifies cold agglutinins as the cause for the mismatch between hematocrit and hemoglobin values. MATERIALS AND METHODS 70-year old female patient had a history of cerebrovascular diseases and rheumatoid arthritis. During routine laboratory examin...

Background: Previous studies have suggested benefits of sodium glucose co-transporter 2 (SGLT2) inhibitors including improving glycemic control, lower body weight, uric acid-lowering effect and decreasing blood pressure. The aim this study was to evaluate the effects SGLT2 on hematocrit (Hct) levels in patients with type diabetes mellitus.

Brain tissue lactate, pyruvate, and adenosine triphosphate (ATP) were measured 60 min after bilateral carotid ligation in spontaneously hypertensive rats, of which hematocrit (HCT) was varied by exchanging with isovolemic homologous red cells, plasma or whole blood. Supratentorial lactate of the ischemic brain was increased more in high HCT (greater than or equal to 50%) and less in low HCT (30...

BACKGROUND Hematocrit (HCT) is known to be a confounding factor that interferes with many blood glucose (BG) measurement technologies, resulting in wrong readings. Dynamic electrochemistry has been identified as one possible way to correct for these potential deviations. The purpose of this laboratory investigation was to assess the HCT stability of four BG meters known to employ dynamic electr...

conclusions the association of the 1st trimester high hb and hct with preeclampsia was revealed in this study, therefore it could be used as a prediction factor for early preeclampsia diagnosis. results preeclampsia incidence was 5.1% in our study. mean hb was 12.38 ± 1.69 g/dl in the preeclampsia group and 11.8 ± 1.18 in the non-preeclampsia group, and mean hct was 37.74 ± 5.15% in the preecla...

This paper presents a unique technical approach to measure the proportion of blood volume occupied by red blood cells, the hematocrit value (HCT) on-line and in-line. A practical method has been developed to measure without the need for extracting blood samples out of an existing extracorporeal blood circulation system. The new sensor is based on Impedance Spectroscopy and measures electrical p...

The extent to which hematocrit (Hct) is regulated and the impact of altered Hct on blood oxygen transport in avian embryos are largely unknown. Consequently, we investigated how acute blood removal or Ringer solution injection modified Hct in day 15 embryos, and how ;blood doping' with erythrocyte-enriched whole blood influenced O(2) consumption in day 15-17 chicken embryos. Mean Hct (+/-s.e.m....
