In 10 male domestic pigs the pulmonary arterial pressure, aortic arch pressure, femoral arterial pressure (PP) and cardiac output by thermodilution technique were measured in four different stages: (I) basal, in spontaneous ventilation; (II) after controlled hemorrhage to simulate the hypovolemic ...
ARV: average real variability; AUC: area under the curve; CI: confidence interval; CV: coefficient of variation; DMM: difference maximum-minimum; MSC: maximal successive change; PP: pulse pressure; PPV: pulse pressure variability; SD: standard deviation; SV: successive variation. are not ...
Pulse transit time (PTT), which refers to the travel time between two arterial sites within the same cardiac cycle, has been developed as a novel cuffless form of continuous blood pressure (BP) monitoring. The aim of this study was to investigate differences in BP parameters, including BP va...
pulse pressure (mmHg), white blood cell count (×103/μl), red blood cell count (×104/μl), platelet count (×103/μl), hematocrit (%), and the estimated glomerular filtration rate (eGFR, ml/min/1.73 m2), which can be obtained using a simple formula from the Japanese Modificati...

Computational arterial blood oxygen saturation (SaO2calc) was calculated based on the measurement of partial pressure of oxygen (PaO2) in arterial blood gas analysis using formulae described earlier [19]. The corrected PaO2 values, which also consider the foal's body temperature, ...
A cardiovascular parameter such as cardiac output is estimated from a current pressure waveform data set without needing to directly measure blood flow or arterial compliance. The general shape of an
Motion artifacts provide one of the greatest design challenges to a PPG measurement system. When motion is present, the width of the arteries and veins change due to pressure. The amount of light absorbed by the photodiode changes and this is present on the PPG signal because photons are abso...
Pressure waves were recorded at the ascending, and proximal and distal abdominal aortas in 13 male normal and KHC rabbits aged 12 months under pentobarbital anesthesia when angiotensin II or sodium nitroprusside was infused intravenously. AoPWV was compared between the two rabbit groups at different ...
The sensation felt depends greatly on where the doctor places their fingers on the patient's radial pulse, how much pressure they use, and on which level (deep or superficial) they feel the pulse. Consequently, it is important to assess the consistency of these methods. The traditional method...
