Effect of Increase and Decrease In Erythrocyte Volume Upon Plasma Volume and Total Blood Volume
… to know if this were a true anemia or if plasma volume shifts occurred which gave a picture of anemia while it did not actually exist. It is the purpose of this paper to determine that factor and to further test it by the study of plasma volume changes in dogs made polycythemic by the …

A Temporal Encoder-Decoder Approach to Extracting Blood Volume Pulse Signal Morphology from Face Videos
This thesis considers methods for extracting blood volume pulse (BVP) representations from video of the human face. Whereas most previous systems have been concerned with estimating vital signs such as average heart rate, this thesis addresses the more difficult problem of recovering BVP signal …

Effect of Blood Volume Manipulations and Warm Acclimation on Cortisol Levels in the Antarctic Teleost Trematomus bernacchii
Antarctic fish, such as the Trematomus bemacchii, maintain a serum osmolality of around 600 mOsm, nearly twice that of temperate fish. This high serum osmolality seawater surrounding Antarctica. Upon warm acclimation Antarctic fish lower their serum osmolality, increase their drinking rate, and …

Extraction of Blood Volume Pulse Morphology from Facial Videos Using an LSTM-Based Temporal Encoder-Decoder Model
This thesis introduces a method for extracting blood volume pulse (BVP) signals from facial videos, moving beyond basic heart rate estimation to capture full pulse waveforms. Our approach adapts techniques from audio signal separation and applies them to video, using a machine learning model …

Hematocrit, hematocrit Regulation and its effect on oxygen consumption in the late stage chicken embryo (Gallus domesticus).
… either repeated saline injections (5% of total blood volume) or repeated blood removal (5% of total blood volume). Embryos showed an ability to maintain hematocrit (~20%) despite blood volume increases up to 115% of initial blood volume. Embryos were not able to maintain hematocrit in the face …

Blood Reservoir Function of the Fetal Guinea Pig Liver
<p>To determine of the fetal liver functions as a blood reservoir, we measured liver blood volume under normal conditions and after hemorrhage and volume loading. Nineteen pregnant guinea pig sows and 54 near-term fetuses were injected intravenously with <sup>51</sup>Cr-labeled red cells while the …

Novel model of cerebrospinal fluid dynamics based on hemodynamically driven cyclic brain compliance variation
… in each cycle is responsible not only for the blood flow, but also for the CSF circulation. This mechanism is based on a cyclic variation of brain compliance, dependent on the blood volume inside the brain vessels. As the cardiac cycle changes the blood volume inside the vessels, it also …

Blood and Plasma Volume Determinations With the Evans Blue Dye (T-1824) Method: a Clinical Investigation With Special Reference to the Blood and Plasma Volume Changes Following Transfusions, and in the Treatment of Cardiac Decompensation
… shown much interest in the red cell and plasma volumes in different clinical conditions. This paper represents, first, an investigation of the Evans Blue dye (T-1824) method of determining the blood volume; and, second, an application of this method in the study of the changes in the red cell …

Design and analysis of fingernail sensors for measurement of fingertip touch fouce and finger posture
… are then used to determine changes in the blood volume under the fingernail, a technique termed "reflectance photoplethysmography." By arranging the LEDs and photodetectors in a spatial array, the two-dimensional pattern of blood volume can be measured and used to predict the touch force …

The severity of stages estimation during hemorrhage using error correcting output codes method
… making system aims at estimating the severity of blood volume loss. Specifically speaking, accompanying many traumatic injuries, severe hemorrhage, a potentially life-threatening condition that requires immediate treatment, is a significant loss of blood volume in process resulting in decreased …

Exercise Induced Hypervolemia: Role of Exercise Mode
… has been shown to limit exercise-induced plasma volume expansion. Differences in hydrostatic pressure gradients between the standing and seated position indicate that treadmill exercise might promote a greater plasma volume expansion than cycle ergometer exercise. To test this hypothesis ten …
