Hematocrit monitor

Critical Care Medicine, 1989
The purpose of this study is to determine experimentally the optimal incident visible wavelength and light detector angle that yields the maximal change in optical density between an arterial or venous Hct of 20% and 40%. A universal monochromator allows incident wave-lengths in 8-nm increments over the visible range to be selected for the incident ...

The Role of the Hematocrit in Bleeding

Transfusion Medicine Reviews, 1987
Low hematocrit is an often neglected cause in the pathogenesis of a prolonged bleeding time in an anemic patient. There has been ample evidence in the literature, indicating a relationship between hematocrit and the bleeding time; and that the transfusion of RBCs may correct the prolonged bleeding time often observed in anemic patients.

Hematocrit‐corrected Pulmonary Vascular Resistance

American Journal of Respiratory and Critical Care Medicine, 2018
The diagnosis and evaluation of severity of pulmonary vascular disease rests on the invasive determination of a pulmonary vascular resistance (PVR).

Measurement of the hematocrit using paper-based microfluidic devices.

Lab on a Chip, 2016
The quantification of blood cells provides critical information about a patient's health status. Sophisticated analytical equipment, such as hematology analyzers, have been developed to perform these measurements, but limited-resource settings often lack

Acoustofluidic hematocrit determination

Analytica Chimica Acta, 2018
Hematocrit (HCT) measurements of blood from patients, blood donors and athletes are routinely performed on a daily basis. These measurements are often performed in centralized hospital labs by whole blood analyzers, which leads to long time-to-result.

The Hematocrit of Capillary Blood

New England Journal of Medicine, 1955
THE measurement of the packed red-cell volume (or hematocrit) of the venous blood has long been recognized as a useful aid in the study of blood in a large number of clinical conditions.

MODE OF DELIVERY AND NEONATAL HEMATOCRIT [PDF]

American Journal of Perinatology, 2000
The objective of this paper is to test the hypothesis that the 2-h hematocrit (HCT) is lower in infants born by cesarean section (CS) than in infants born vaginally and that the postnatal rise of HCT is lower in infants born by CS than in infants delivered vaginally.

Hematocrit measurement by dielectric spectroscopy

Proceedings of the Second Joint 24th Annual Conference and the Annual Fall Meeting of the Biomedical Engineering Society] [Engineering in Medicine and Biology, 2002
Based on permittivity changes, a new method to measure hematocrit (HCT) in extracorporeal blood systems is presented. Human blood samples were tested at different HCT levels pairing the values of permittivity change, obtained by means of a commercial impedance analyzer, with traditional centrifugation measurements.

Influence of Lipid Emulsion for the Hematocrit Value Measured With Continuous Hematocrit Monitor

ASAIO Journal, 2007
Continuous monitoring of hematocrit with a CRIT-LINE monitor (CLM) is used to prevent excess ultrafiltration during hemodialysis and continuous renal replacement therapy. The presence of substances affecting the scattering and absorption rates of multiple wavelengths of near infrared rays of CLM in the blood may affect the measured values with CLM.

Optimal hematocrit for hemodialysis

Current Opinion in Nephrology and Hypertension, 1997
Considerable controversy continues over the optimal hematocrit target for dialysis patients being treated with recombinant erythropoietin. Recent short-term studies have demonstrated a significant improvement in brain function when hematocrit is 42% compared with when it is 31%.
