Hematocrit of the human cranial blood pool.
• Since the hematocrit of arteriolar and capillary blood is substantially lower than that found in larger vessels, the mean hematocrit of total organs will be lower than the large vessel hematocrit, particularly in organs, such as human brain, that contain very rich capillary beds. This has been demonstrated in many tissues.-~' It is the purpose of this article to describe a basic technique for...
متن کاملIncreasing the Accuracy of Blood Hematocrit Measurement by Triplicate Wavelength Photoplethysmography Method
Background and objectives: The importance of continuous monitoring and rapid and accurate informing of changes in blood components (e.g., percentage of hematocrit [HCT]), especially in acute conditions, has motivated researchers to use non-invasive measurement methods. Therefore, this study aimed to evaluate the association between blood HCT and photoplethysmographic signal and the possibility ...
متن کاملAcute stroke, hematocrit, and blood pressure.
A population-based study of the relation between hematocrit and stroke subtype was carried out among 2,077 individuals using the Lehigh Valley Stroke Register. This register identifies all stroke patients admitted to the 8 acute care hospitals serving the Lehigh Valley area of eastern Pennsylvania-western New Jersey. The mean hematocrit was higher in patients with lacunes than with thrombotic o...
متن کاملTHE PIVOTAL ROLE OF CRANIAL NERVER DECOMPRESSION
Reported are a total of 81 microsurgical operations for cranial nerve root decompression comprising of 66 trigeminal, 10 facial, one vestibular, one vagus and three accessory nerve dysfunction syndromes from 1983 to 1990. Almost all cases of trigeminal neuralgia (TNG) secondary to vascular (59 cases) and minute mass (10 cases) compression, and those with hemifacial spasm (HFS) (nine out o...
متن کاملThe hematocrit paradox--how does blood doping really work?
The wide-spread assumption that doping with erythropoietin or blood transfusion is only effective by increasing arterial blood O2 content because of rising hematocrit is not self-evident. "Natural blood dopers" (horses, dogs) increase both hematocrit and circulating blood volume during exercise by releasing stored erythrocytes from the spleen. Improvement of aerobic performance by augmenting he...
