measurement of the stroke volume and its changes over time can be very helpful for diagnosis of dysfunctions in the blood circulatory system and monitoring their treatments. impedance cardiography (icg) is a simple method of measuring the stroke volume based on changes in the instantaneous mean impedanceof the thorax. this method has received much attention in the last two decades because it is...

BACKGROUND Safety of blood donors rest on withdrawing only appropriate quantities of blood. Adjusting the volumes drawn according to the average blood volumes of any population can ensure this. This requires knowledge of total blood volume of donors, which should ideally be measured by standard methods or derived by alternate suitable method. This observational, cross sectional study was undert...

Massive blood transfusion is defined as the loss of one or more circulating blood volumes. It is, therefore, important to calculate the patient’s estimated blood volume (EBV) and to relate this to the volume of blood products and other fluids administered (Table 1). In addition the anesthesiologist should estimate how much blood will be allowed to be lost before the initiation of packed RBC tra...

BACKGROUND Blood culture volume is the most important variable in detecting bacteremia and fungemia. However, the majority of hospitals in Taiwan do not meet the criteria for an ideal blood culture volume (8-10 mL per bottle, two bottles per set) during collection. METHODS The object of this study is to initiate an educational program for healthcare workers to increase blood volume collection...

Hematocrit is a blood test that is defined as the volume percentage of red blood cells in the whole blood. It is one of the important indicators for clinical decision making and the most effective factor in glucose measurement using handheld devices. In this paper, a method for hematocrit estimation that is based upon the transduced current curve and the neural network is presented. The salient...

introduction blood pressure (bp) is one of the important vital signs that need to be monitored for personal healthcare. arterial blood pressure is estimated from pulse transit time (ptt). this study uses two pulse sensors to get ptt. the aim of this study was to construct an optical system and to monitor blood pressure continuously and without cuff in people with different ages. materials and m...

The assessment of the level of hydration in the intravascular fluid compartment in acute renal failure (ARF) and multiple organ failure (MOF) is of an utmost importance. However, the data on monitoring of blood volume in these diseases and especially during haemodialysis treatment are lacking. This article summarizing the experience of monitoring of blood volume in chronic haemodialysis suggest...

background : diabetes mellitus is a chronic disease with a worldwide prevalence and its complications can be prevented with close monitoring of blood glucose. quality of blood glucose monitoring utilizing glucometers in iranian hospitalized patients has not been well published in the literature. we evaluated the accuracy and consistency of the results of two devices compared with the standard l...

conclusions our study could not show any correlation between sleep quality and ambulatory bp monitoring parameters in children with abnormal bp. objectives the aim of this study was to investigate the correlation between sleep quality parameters and blood pressure (bp) changes in children. patients and methods eighty six patients aged 5-15 years old with the history of urinary tract infection w...
