Hematocrit
The volume of packed RED BLOOD CELLS in a blood specimen. The volume is measured by centrifugation in a tube with graduated markings, or with automated blood cell counters. It is an indicator of erythrocyte status in disease. For example, ANEMIA shows a low value; POLYCYTHEMIA, a high value.
Hemodilution
Reduction of blood viscosity usually by the addition of cell free solutions. Used clinically (1) in states of impaired microcirculation, (2) for replacement of intraoperative blood loss without homologous blood transfusion, and (3) in cardiopulmonary bypass and hypothermia.
Blood Viscosity
The internal resistance of the BLOOD to shear forces. The in vitro measure of whole blood viscosity is of limited clinical utility because it bears little relationship to the actual viscosity within the circulation, but an increase in the viscosity of circulating blood can contribute to morbidity in patients suffering from disorders such as SICKLE CELL ANEMIA and POLYCYTHEMIA.
Erythrocyte Count
The number of RED BLOOD CELLS per unit volume in a sample of venous BLOOD.
Plasma Volume
Volume of PLASMA in the circulation. It is usually measured by INDICATOR DILUTION TECHNIQUES.

Erythropoietin
Glycoprotein hormone, secreted chiefly by the KIDNEY in the adult and the LIVER in the FETUS, that acts on erythroid stem cells of the BONE MARROW to stimulate proliferation and differentiation.
Anemia
A reduction in the number of circulating ERYTHROCYTES or in the quantity of HEMOGLOBIN.
Polycythemia
An increase in the total red cell mass of the blood. (Dorland, 27th ed)
Erythrocyte Volume
Volume of circulating ERYTHROCYTES . It is usually measured by RADIOISOTOPE DILUTION TECHNIQUE.
Blood Volume
Volume of circulating BLOOD. It is the sum of the PLASMA VOLUME and ERYTHROCYTE VOLUME.
Exchange Transfusion, Whole Blood

Used in treatment of fetal erythroblastosis, hepatic coma, sickle cell anemia, disseminated intravascular coagulation, septicemia, burns, thrombotic thrombopenic purpura, and fulminant malaria.
Erythrocyte Indices
ERYTHROCYTE size and HEMOGLOBIN content or concentration, usually derived from ERYTHROCYTE COUNT; BLOOD hemoglobin concentration; and HEMATOCRIT. The indices include the mean corpuscular volume (MCV), the mean corpuscular hemoglobin (MCH), and the mean corpuscular hemoglobin concentration (MCHC).

Erythrocyte Aggregation
The formation of clumps of RED BLOOD CELLS under low or non-flow conditions, resulting from the attraction forces between the red blood cells. The cells adhere to each other in rouleaux aggregates. Slight mechanical force, such as occurs in the circulation, is enough to disperse these aggregates. Stronger or weaker than normal aggregation may result from a variety of effects in the ERYTHROCYTE MEMBRANE or in BLOOD PLASMA. The degree of aggregation is affected by ERYTHROCYTE DEFORMABILITY, erythrocyte membrane sialylation, masking of negative surface charge by plasma proteins, etc. BLOOD VISCOSITY and the ERYTHROCYTE SEDIMENTATION RATE are affected by the amount of erythrocyte aggregation and are parameters used to measure the aggregation.
Blood Cell Count

The number of PLATELETS per unit volume in a sample of venous BLOOD.
Anemia, Hypochromic
Anemia characterized by a decrease in the ratio of the weight of hemoglobin to the volume of the erythrocyte, i.e., the mean corpuscular hemoglobin concentration is less than normal. The individual cells contain less hemoglobin than they could have under optimal conditions. Hypochromic anemia may be caused by iron deficiency from a low iron intake, diminished iron absorption, or excessive iron loss. It can also be caused by infections or other diseases, therapeutic drugs, lead poisoning, and other conditions. (Stedman, 25th ed; from Miale, Laboratory Medicine: Hematology, 6th ed, p393)

Relaxin is a potent renal vasodilator in conscious rats. (1/3107)

The kidneys and other nonreproductive organs vasodilate during early gestation; however, the "pregnancy hormones" responsible for the profound vasodilation of the renal circulation during pregnancy are unknown. We hypothesized that the ovarian hormone relaxin (RLX) contributes. Therefore, we tested whether the administration of RLX elicits renal vasodilation and hyperfiltration in conscious adult, intact female rats. After several days of treatment with either purified porcine RLX or recombinant human RLX 2 (rhRLX), effective renal plasma flow (ERPF) and glomerular filtration rate (GFR) increased by 20%-40%. Comparable renal vasodilation and hyperfiltration was also observed in ovariectomized rats, suggesting that estrogen and progesterone are unnecessary for the renal response to rhRLX. The nitric oxide synthase inhibitor Nomega-nitro-L-arginine methyl ester completely abrogated the increase in ERPF and GFR elicited by chronic administration of purified porcine RLX. In contrast, the renal vasoconstrictory response to angiotensin II was attenuated by the RLX treatment. Short-term infusion of purified porcine RLX to conscious rats over several hours failed to increase ERPF and GFR. Plasma osmolality was consistently reduced by the chronic administration of both RLX preparations. In conclusion, the renal and osmoregulatory effects of chronic RLX administration to conscious rats resemble the physiological changes of pregnancy in several respects: (a) marked increases in ERPF and GFR with a mediatory role for nitric oxide; (b) attenuation of the renal circulatory response to angiotensin II; and (c) reduction in plasma osmolality.  (+info)

O-raffinose cross-linking markedly reduces systemic and renal vasoconstrictor effects of unmodified human hemoglobin. (2/3107)

The hemodynamic effects of a 20% exchange-transfusion with different solutions of highly purified human hemoglobin A-zero (A0) were evaluated. We compared unmodified hemoglobin with hemoglobin cross-linked with O-raffinose. Unmodified hemoglobin increased systemic vascular resistance and mean arterial pressure more than the O-raffinose cross-linked hemoglobin solution (by approximately 45% and approximately 14%, respectively). Unmodified hemoglobin markedly reduced cardiac output (CO) by approximately 21%, whereas CO was unaffected by the O-raffinose cross-linked hemoglobin solution. Unmodified and O-raffinose cross-linked hemoglobin solutions increased mean arterial pressure to comparable extents ( approximately 14% and approximately 9%, respectively). Unmodified hemoglobin increased renal vascular resistance 2-fold and reduced the glomerular filtration rate by 58%. In marked contrast, the O-raffinose cross-linked hemoglobin had no deleterious effect on the glomerular filtration rate, renal blood flow, or renal vascular resistance. The extents to which unmodified and O-raffinose cross-linked hemoglobin solutions inactivated nitric oxide also were compared using three separate in vitro assays: platelet nitric oxide release, nitric oxide-stimulated platelet cGMP production, and endothelium-derived relaxing factor-mediated inhibition of platelet aggregation. Unmodified hemoglobin inactivated or oxidized nitric oxide to a greater extent than the O-raffinose cross-linked hemoglobin solutions in all three assays. In summary, O-raffinose cross-linking substantially reduced the systemic vasoconstriction and the decrease in CO induced by unmodified hemoglobin and eliminated the deleterious effects of unmodified hemoglobin on renal hemodynamics and function. We hypothesize that O-raffinose cross-linking reduces the degree of oxidation of nitric oxide and that this contributes to the reduced vasoactivity of this modified hemoglobin.  (+info)

Septicemia in dialysis patients: incidence, risk factors, and prognosis. (3/3107)

BACKGROUND: Infection is second to cardiovascular disease as a cause of death in patients with end-stage renal disease (ESRD), and septicemia causes a majority of these infectious deaths. To identify patients at high risk and to characterize modifiable risk factors for septicemia, we examined the incidence, risk factors, and prognosis for septicemia in a large, representative group of U.S. dialysis patients. METHODS: We conducted a longitudinal cohort study of incident ESRD patients in the case-mix study of the U.S. Renal Data System with seven years of follow-up from hospitalization and death records. Poisson regression was used to examine independent risk factors for hospital-managed septicemia. Cox proportional hazards analysis was used to assess the independent effect of septicemia on all-cause mortality and on death from septicemia. Separate analyses were performed for patients on peritoneal dialysis (PD) and hemodialysis (HD). RESULTS: Over seven years of follow-up, 11.7% of 4005 HD patients and 9.4% of 913 PD patients had at least one episode of septicemia. Older age and diabetes were independent risk factors for septicemia in all patients. Among HD patients, low serum albumin, temporary vascular access, and dialyzer reuse were also associated with increased risk. Among PD patients, white race and having no health insurance at dialysis initiation were also risk factors. Patients with septicemia had twice the risk of death from any cause and a fivefold to ninefold increased risk of death from septicemia. CONCLUSIONS: Septicemia, which carries a marked increased risk of death, occurs frequently in patients on PD as well as HD. Early referral to a nephrologist, improving nutrition, and avoiding temporary vascular access may decrease the incidence of septicemia. Further study of how race, insurance status, and dialyzer reuse can contribute to the risk of septicemia among ESRD patients is indicated.  (+info)

Evaluation of pulmonary volumetric morphometry at the light and electron microscopy level in several species of passerine birds. (4/3107)

The lungs of 3 small passerine species, having similar body mass but different diurnal activity patterns, were analysed morphometrically to assess the relationship between diurnal activity and pulmonary volumetry at the light and electron microscope levels. The percentage volumes of the major lung and exchange tissue components of the 3 species--an aerial insectivore, a foliage gleaner/nectarivore and a ground forager--were strikingly similar, and consistent with literature values for other passerine species. The only significant difference found was exchange tissue plasma volume and pulmonary haematocrit, with the ground-foraging, low activity Malurus splendens having significantly lower values than the other 2 species. This may indicate that cardiovascular parameters are more important determinants of metabolic activity in small passerines than aspects of pulmonary anatomy.  (+info)

Hematocrit correlates with blood pressure in young male office workers. (5/3107)

High hematocrit (Ht) level has been reported to be a correlating factor of hypertension in aged people, but has not been examined in younger generation. To investigate the association between Ht and blood pressure (BP) in healthy young workers, statistical analysis was performed for 646 male employees, using cross-sectional health-check data. Ht was positively correlated with systolic blood pressure (SBP) and with diastolic blood pressure (DBP) by Pearson's simple correlation analysis. Multiple regression analysis for SBP and DBP was conducted by stepwise procedure, using Ht, age, body mass index (BMI), and drinking and smoking habits as independent variables. It was revealed that Ht was a significant independent variable for DBP (p < 0.001), as well as age and BMI, but not for SBP. These findings suggest that increased Ht is an important variable for assessing risk for cardiovascular disorders, especially diastolic hypertension, in young male office workers.  (+info)

Maintenance of normal agonist-induced endothelium-dependent relaxation in uraemic and hypertensive resistance vessels. (6/3107)

BACKGROUND: The nitric oxide system has been implicated in several diseases with vascular complications including diabetes mellitus and hypertension. Despite the high prevalence of hypertension and cardiovascular complications in renal failure few studies have examined vascular and endothelial function in uraemia. We therefore chose to study possible abnormalities of the nitric oxide vasodilator system in an animal model of chronic renal failure. METHODS: Adult spontaneous hypertensive rats and Wistar Kyoto rats were subjected to a 5/6 nephrectomy with control animals having sham operations. After 4 weeks blood pressure was recorded and the animals were sacrificed. Branches of the mesenteric arteries were isolated and mounted on a Mulvany myograph. All experiments were performed in the presence of indomethacin (10(-5) M). The vessels were first preconstricted with noradrenaline, exposed to increasing concentrations of acetylcholine (10(-8) to 10(-4) M) and subsequently to sodium nitroprusside (10(-5) M). RESULTS: There was no difference in the relaxation of the four groups of vessels to any of the concentrations of acetylcholine used nor was there any significant difference in the EC50s (control Wistar Kyoto 6.1+/-1.4 x 10(-8) M; uraemic Wistar Kyoto 5.4+/-0.8 x 10(-8) M; control spontaneous hypertensive rats 4.5+/-0.6 x 10(-8) M; uraemic spontaneous hypertensive rats 6+/-0.7 x 10(-8) M). Vasodilatation in response to sodium nitroprusside was unchanged in uraemic vessels. In addition the vascular responses to both acetylcholine and sodium nitroprusside were unaltered in spontaneous hypertensive rats. CONCLUSIONS: We conclude that normal agonist-induced endothelium-dependent relaxation is maintained in experimental uraemia and hypertension.  (+info)

Mechanism for the posture-specific plasma volume increase after a single intense exercise protocol. (7/3107)

To test the hypothesis that exercise-induced hypervolemia is a posture-dependent process, we measured plasma volume, plasma albumin content, and renal function in seven healthy subjects for 22 h after single upright (Up) or supine (Sup) intense (85% peak oxygen consumption rate) exercise. This posture was maintained for 5 h after exercise. Plasma volume decreased during exercise but returned to control levels by 5 h of recovery in both postures. By 22 h of recovery, plasma volume increased 2.4 +/- 0.8 ml/kg in Up but decreased 2.1 +/- 0.8 ml/kg in Sup. The plasma volume expansion in Up was accompanied by an increase in plasma albumin content (0.11 +/- 0.04 g/kg; P < 0.05). Plasma albumin content was unchanged in Sup. Urine volume and sodium clearance were lower in Up than Sup (P < 0.05) by 5 h of recovery. These data suggest that increased plasma albumin content contributes to the acute phase of exercise-induced hypervolemia. More importantly, the mechanism by which exercise influences the distribution of albumin between extra- and intravascular stores after exercise is altered by posture and is unknown. We speculate that factors associated with postural changes (e.g., central venous pressure) modify the increase in plasma albumin content and the plasma volume expansion after exercise.  (+info)

Efficacy of recombinant human Hb by 31P-NMR during isovolemic total exchange transfusion. (8/3107)

The ability of recombinant human Hb (rHb1.1), which is being developed as an oxygen therapeutic, to support metabolism was measured by in vivo 31P-NMR surface coil spectroscopy of the rat abdomen in control animals and in animals subjected to isovolemic exchange transfusion to hematocrit of <3% with human serum albumin or 5 g/dl rHb1.1. No significant changes in metabolite levels were observed in control animals for up to 6 h. The albumin-exchange experiments, however, resulted in a more than eightfold increase in Pi and a 50% drop in phosphocreatine and ATP within 40 min. The tissue pH dropped from 7.4 to 6.8. The decrease in high-energy phosphates obeyed Michaelis-Menten kinetics, with a Michaelis-Menten constant of 3% as the hematocrit at which a 50% drop in high-energy phosphates was observed. Exchange transfusion with rHb1.1 resulted in no significant drop in high-energy phosphates, no rise in Pi, and no change in tissue pH from 7.35 +/- 0.15 for up to 5 h after exchange. By these criteria, rHb1.1 at a plasma Hb concentration of approximately 5 g/dl after total exchange transfusion was able to sustain energy metabolism of gut tissue at levels indistinguishable from control rats with a threefold higher total Hb level in erythrocytes.  (+info)

Elevated hematocrit enhances platelet accumulation following vascular injury | Blood JournalElevated hematocrit enhances platelet accumulation following vascular injury | Blood Journal
Red blood cells (RBCs) demonstrate procoagulant properties in vitro, and elevated hematocrit is associated with reduced bleeding and increased thrombosis risk in humans. These observations suggest RBCs contribute to thrombus formation. However, effects of RBCs on thrombosis are difficult to assess because humans and mice with elevated hematocrit typically have co-existing pathologies. Using an experimental model of elevated hematocrit in healthy mice, we measured effects of hematocrit in two in vivo clot formation models. We also assessed thrombin generation, platelet-thrombus interactions, and platelet accumulation in thrombi ex vivo, in vitro, and in silico. Compared to controls, mice with elevated hematocrit (RBCHIGH) formed thrombi at a faster rate and had a shortened vessel occlusion time. Thrombi in control and RBCHIGH mice did not differ in size or fibrin content, and there was no difference in levels of circulating thrombin-antithrombin complexes. In vitro, increasing the hematocrit ...

Blood Tests for Preeclampsia - Genesis HealthCare System - Zanesville, OhioBlood Tests for Preeclampsia - Genesis HealthCare System - Zanesville, Ohio
Hematocrit. A high hematocrit value can be a sign of preeclampsia. Hematocrit tells the percentage of red blood cells in the blood-a hematocrit value of 42 means that red blood cells make up 42% of the blood volume. A normal hematocrit value for a nonpregnant woman is between 36% and 44%. During pregnancy, the hematocrit value normally decreases-the fluid in the blood (plasma) increases, making red blood cells less concentrated. But preeclampsia often causes the bodys tissues to absorb blood plasma. The blood becomes more concentrated, resulting in an abnormally high hematocrit value ...

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 (30-39%) compared with normal HCT (40-49%). In very low HCT (less than 30%), however, lactate was increased to further extent compared with any other group of HCT (ANOVA p less than 0.0001). Lactate/pyruvate (L/P) ratio of the ischemic brain showed similar changes, namely U-shaped correlation to HCT. In contrast, supratentorial ATP was decreased more markedly in very low HCT, followed by high and normal HCT, and minimally decreased in low HCT, demonstrating an inverse U-shaped relationship to HCT. Mean arterial pressure and arterial acid-base parameters in ischemic animals did not differ among HCT groups. ...

In patients with hematocrit of 60% or above the A blood viscosity is increased, and the tissue oxygenation is compromised. There is an increased incidence of cardiovascular complications. Immediate phlebotomy is often done, but if the red cell volume is not increased and the plasma volume and total blood volume are decreased, phlebotomy may be harmful. Twenty-five patients with hematocrits of 60% or above have been studied. Patients with clinical or laboratory evidence of dehydration are not included. Red cell volume was determined by chromium-51 and plasma volume by iodine-131 human serum. The expected red cell volume and plasma volume ...

Chronic Anemia - Chicago Disability AttorneyChronic Anemia - Chicago Disability Attorney
Anemia is a condition in which there is a decrease in circulating hemoglobin, the chemical that combines with oxygen and carries it to cells. Since red blood cells contain hemoglobin, the severity of anemia is usually gauged by the hematocrit (Hct), which is the percentage of red cells in a volume of blood. In women, a normal hematocrit (at sea level) is about 38-44% and in men about 42-48%. Physical exertion requires increased blood flow for oxygenation of both the heart muscle and the skeletal muscles. A person with a low hematocrit will need a faster heart and respiratory rate for a particular level of exertion so that, for example, a persons maximum heart rate could be reached doing light work. To the extent that those demands cannot be met because of decreased oxygen carriers (red cells), symptoms of fatigue, weakness, and increased respiratory effort with shortness of breath will limit exercise capacity. These symptoms are not different than those of a normal person who reaches his or her ...

PV is a myeloproliferative disorder resulting in an elevated absolute red blood cell mass because of uncontrolled red blood cell production. This is typically associated with an increase in WBC and PLT production. The increase in WBCs and PLTs is secondary to an abnormal clone of hematopoietic stem cells with increased sensitivity to different maturation growth factors. PV is overall rare, occurring in 0.6-1.6 persons per million population. The peak incidence of PV is 50-70 years of age. However, PV may occur in persons of all age groups, including young adults and children, albeit rarely [11].. The increased hematocrit of PV is the main determinant of blood viscosity. As the viscosity increases, cerebral blood flow decreases [6, 7]. PLT marginalization with increased contact to vessel walls occurs, along with local effect of a high hematocrit on vessel walls [6, 7]. This fulfils all three components of Virchows triad [12], and is consistent with the thought that many strokes in polycythemic ...

Children with sickle cell disease suffer impairment of cognitive function (1-3, 8-18). Although some studies report little or no cognitive impairment among patients with no history of clinical stroke (9,16,18), a general consensus exists that patients with clinical stroke do show cognitive impairment (1,8,13,15). We herein confirm that patients with silent infarct have cognitive impairment, compared with patients with normal MR imaging findings (Tables 2 and 5). However, we observed that patients who have completely normal MR imaging findings can still show significant cognitive impairment with respect to normative data (Tables 2 and 5), suggesting that MR imaging is not sensitive to some types of damage that can produce cognitive impairment. The degree of impairment is greater in children with low hematocrit (Table 3), and hematocrit alone is able to explain approximately 23% of the variance in full-scale intelligence quotient (Table 4). Furthermore, abnormal MR imaging and low hematocrit are ...

I had a Lyme Titer done, which came back negative. I do not know what type of Titer was done, if they did the old ELISA test or the ELISA6 test and I assume they did not do the western blot.

hematocrit | The Trauma Prohematocrit | The Trauma Pro
Does Initial Hematocrit Predict Shock?. Everything you know is WRONG!. The classic textbook teaching is that trauma patients bleed whole blood. And that if you measure the hematocrit (or hemoglobin) on arrival, it will approximate their baseline value because not enough time has passed for equilibration and hemodilution. As Ive said before, youve got to be willing to question dogma!. The trauma group at Ryder in Miami took a good look at this assumption. They drew initial labs on all patients requiring emergency surgery within 4 hours of presentation to the trauma center. They also estimated blood loss in the resuscitation room and OR and compared it to the initial hematocrit. They also compared the hematocrit to the amount of crystalloid and blood transfused in those areas.. Patients with lower initial hematocrits had significantly higher blood loss and fluid and blood replacement during the initial treatment period. Some of this effect may be due to the fact that blood loss was ...

AUTHORS: Kim, Won Ho MD, PhD et al. Anesthesia & Analgesia: May, 2017. BACKGROUND: Although point-of-care (POC) analyzers are commonly used during liver transplantation (LT), the accuracy of hematocrit measurement using a POC analyzer has not been evaluated. In this retrospective observational study, we aimed to evaluate the accuracy of hematocrit measurement using a POC analyzer and identify potential contributors to the measurement error and their influence on mistransfusion during LT.. METHODS: We retrospectively collected 6461 pairs of simultaneous intraoperative hematocrit measurements using POC analyzers and laboratory devices during LTs in 901 patients. The agreement of hematocrit measurements was assessed using Bland-Altman analysis for repeated measurements, while the incidence and magnitude of hematocrit measurement error were compared among 16 different laboratory abnormality categories. A generalized estimating equation analysis was performed to identify potential contributors to ...

RenalWEB Outcomes - Anemia Management
Anemia is a common complication of end-stage renal disease (ESRD). Anemia occurs when there is a shortage of red blood cells or when the red blood cells are not correctly formed. In dialysis units, anemia is usually measured by the hematocrit blood test, which reports the percentage of the blood that is comprised of red blood cells. Normally, a hematocrit is from 37% to 47% for women and from 42% to 52% for men. Without interventions, a dialysis patients hematocrit usually stabilizes between 20-25%. At this level, most patients tire easily and feel drained of energy. Several statistical analyses have shown that dialysis patients have signficantly more complications, hospitalizations, and a higher mortality rate when their hematocrit is below 30% (approximately).. Dialysis patients experience anemia (low hematocrit) primarily because their kidneys no longer produce adequate amounts of erythropoietin (EPO). EPO is the principal factor that stimulates red blood cell production in the bone marrow. ...

Influence of feeding hematocrit and perfusion pressure on hematocrit reduction (Fåhræus effect) in an artificial microvascular...
Objective Hct in narrow vessels is reduced due to concentration of fast?flowing RBCs in the center, and of slower flowing plasma along the wall of the vessel, which in combination with plasma skimming at bifurcations leads to the striking heterogeneity of local Hct in branching capillary networks known as the network Fåhræus effect. We analyzed the influence of feeding Hct and perfusion pressure on the Fåhræus effect in an AMVN. Methods RBC suspensions in plasma with Hcts between 20% and 70% were perfused at pressures of 5?60 cm H2O through the AMVN. A microscope and high?speed camera were used to measure RBC velocity and Hct in microchannels of height of 5 ?m and widths of 5?19 ?m. Results Channel Hcts were reduced compared with Hctfeeding in 5 and 7 ?m microchannels, but not in larger microchannels. The magnitude of Hct reduction increased with decreasing Hctfeeding and decreasing ?P (flow velocity), showing an about sevenfold higher effect for 40% Hctfeeding and low pressure/flow velocity ...

Blood has two components: a watery fluid called plasma and the blood cells it transports. The hematocrit measures the fraction of the blood that is solely blood cells, and a healthy young mans is usually about 40 to 45 percent. I had figured that Mr. Chens hematocrit was low because he suffered from chronic anemia, a condition common among many recent immigrants from China. But when a patient is suffering from DKA and dehydration, the hematocrit (or blood cell count) should increase because the other portion of the blood--the plasma, which contains water--has decreased. So Mr. Chens real number of blood cells was probably far below what the already low hematocrit suggested. If he wasnt chronically anemic, then he had recently lost at least one-third of his blood cells. But how? And where ...

These results demonstrate that splenectomy is able to blunt the decline in MAP, the increase in hematocrit, and the reduction in plasma volume that is observed in intact animals infused with a low dose of LPS. It is important to emphasize that the increase in hematocrit observed in the intact animals results from the reduction in plasma volume (Fig. 3) not from splenic contraction and discharge of high hematocrit blood into the circulation. The rat spleen neither is contractile nor does it have storage capacity (32). Moreover, we have previously demonstrated that within the intrasplenic circulation there appears to be a mechanism enabling the efflux of iso-oncotic fluid from the blood into the lymphatic system (24). We propose therefore that during endotoxemia this fluid efflux is exaggerated, resulting in hemoconcentration and hypotension. The second experiment (Study B) supports this suggestion. Despite the initial fall in blood pressure caused by LPS, splenic arterial flow was maintained due ...

Resistance to blood flow in microvessels in vivo. | Circulation ResearchResistance to blood flow in microvessels in vivo. | Circulation Research
Resistance to blood flow through peripheral vascular beds strongly influences cardiovascular function and transport to tissue. For a given vascular architecture, flow resistance is determined by the rheological behavior of blood flowing through microvessels. A new approach for calculating the contribution of blood rheology to microvascular flow resistance is presented. Morphology (diameter and length), flow velocity, hematocrit, and topological position were determined for all vessel segments (up to 913) of terminal microcirculatory networks in the rat mesentery by intravital microscopy. Flow velocity and hematocrit were also predicted from mathematical flow simulations, in which the assumed dependence of flow resistance on diameter, hematocrit, and shear rate was optimized to minimize the deviation between measured and predicted values. For microvessels with diameters below approximately 40 microns, the resulting flow resistances are markedly higher and show a stronger dependence on hematocrit ...

Dr. Sharma and colleagues raise the question of a U-shaped relationship between hematocrit and all-cause mortality. We explored the possibility of a nonlinear relationship between hematocrit and survival time by including a quadratic hematocrit term in the Cox regression (1). The term was not significant, which allowed us to rule out a simple U relationship. We did not present analyses of all-cause mortality itself because follow-up times were quite variable and much of the data was censored. However, as an example of these results, in our data those male patients with hematocrit from 40% to 49% (n = 4,235) had 22% mortality, whereas those male patients with hematocrit of 50 or higher (n = 344) had a mortality of 23%, not a statistically significant difference (p = 0.47). We concluded that a nonlinear model did not fit the data any better than did a linear model..

I dont normally notice this when Im walking around but as soon as I start running or biking (which for me is about 25 days/month), I notice it. My personal 10k best time is 38:42 and Im now running around 70 minutes at altitude. I ran the 38:42 time at sea level 25 years ago so undoubtedly some of the slowdown is just age and altitude.
