Infusion is very important for patients who need additional fluids in the body. Intravenous fluids are injected into the body using needles, through veins. Delayed replacement of IV fluids can pose a very high risk for the patient's condition. One of the risk is that the blood can be sucked back and flow in the IV tube, because there is a difference fluid pressure between the vein and the infusion bag. Therefore, controlling the volume of infusion fluid is very necessary so the infusion bag containing the intravenous fluid must not be used up.To minimize the risk is by replacing the IV bag that must be done in a timely manner. So to find out the amount of infusion fluid volume in the infusion bag it will be designed and realized an instrument that can measure the volume of infusion fluid by weighing the weight of the infusion bag. This tool can stop the flow of IV fluids that flow into veins when the IV fluid will be depleted.The result of this research is that the system will stop the infusion fluid flow by activating the pinch valve by clamping the infusion hose so that the fluid can stop when the infusion fluid volume will run out. Discontinuation of infusion fluid occurs when the remaining infusion fluid volume is 10 mL

Interstitial Fluid Volume

There is clinical and experimental evidence that lack of thyroid hormones may affect the composition and structure of the interstitium. This can influence the relationship between volume and pressure during changes in hydration. Hypothyrosis was induced in rats by thyroidectomy 8 wk before the experiments. Overhydration was induced by infusion of acetated Ringer, 5, 10, and 20% of the body weight, while fluid was withdrawn by peritoneal dialysis with hypertonic glucose. Interstitial fluid pressure (Pi) in euvolemia (euvolemic control situation) and experimental situation was measured with micropipettes connected to a servocontrolled counterpressure system. The corresponding interstitial fluid volume (Vi) was found as the difference between extracellular fluid volume measured as the distribution volume of 51Cr-labeled EDTA and plasma volume measured using125I-labeled human serum albumin. In euvolemia, Vi was similar or lower in the skin and higher in skeletal muscle of hypothyroid than in euthyroid control rats, whereas the corresponding Pi was higher in all tissues. During overhydration, Pi rose to the same absolute level in both types of rats, whereas during peritoneal dialysis there was a linear relationship between volume and pressure in all tissues and types of rats. Interstitial compliance (Ci), calculated as the inverse value of the slope of the curve relating changes in volume and pressure in dehydration, did not differ significantly in the hindlimb skin of hypothyroid and euthyroid rats. However, in skeletal muscle, Ci was 1.3 and 2.0 ml · 100 g−1 · mmHg−1 in hypothyroid and euthyroid rats ( P < 0.01), with corresponding numbers for the back skin of 2.7 and 5.0 ml · 100 g−1 · mmHg−1 ( P < 0.01). These experiments suggest that lack of thyroid hormones in rats changes the interstitial matrix, again leading to reduced Ci and reduced ability to mobilize fluid from the interstitium.

Introduction A number of problems occur in the fields of drilling and rock mechanics for which consideration must be given to the interaction of fluid flow and rock deformation. Such problems include those of borehole stability, chip removal from under a drill bit, drilling in the presence of a fluid pressure gradient between the drilling fluid and formation fluid, and drilling by use of hydraulic jets. We have recently developed a general theory of the influence of fluid pressure gradients and gravity on the plasticity of porous media. The solution of the problem considered here serves as an example of the application of that theory. The illustrative problem is to determine the load required on a flat problem is to determine the load required on a flat axially symmetric punch for incipient plasticity of the porous medium under the punch when fluid flows through the bottom face of the punch. The rock is assumed to behave as a Coulomb plastic material under the influence of body forces plastic material under the influence of body forces due to fluid pressure gradients and gravity. Numerical methods that have been used by Cox et al. for analyzing axially symmetric plastic deformation in soils with gravity force are applied to the problem considered here. Involved is an iterative process for determining the slip lines. The fluid flow field ‘used for calculating the fluid pressure gradient is based upon the work by Ham pressure gradient is based upon the work by Ham in his study of the potential distribution ahead of the bit in rotary drilling. The effective stresses in the porous rock and the punch force for incipient plasticity are computed in terms of the fluid plasticity are computed in terms of the fluid pressure and the cohesive strength and internal pressure and the cohesive strength and internal friction of the rock. PLASTICITY OF POROUS MEDIA PLASTICITY OF POROUS MEDIA A recently developed general theory of plasticity of porous media under the influence of fluid flow is summarized in this section. The equation of motion for the porous solid for the case of incipient plastic deformation reduces to the following equilibrium equation:(1) where Ts is the partial stress tensor of the solid; Fs is the body force acting on the solid per unit volume of the solid material; P is the interaction force between the solid and the fluid; and is the porosity, which is defined as the ratio of the pore porosity, which is defined as the ratio of the pore volume to the total volume of the solid-fluid mixture. The partial stress tensor Ts can be considered as the effective stress tensor that is used in sod mechanics. With the acceptance of the effective stress principle defined in Ref. 5, the yield function, f, in the following form is satisfied for plastic deformation of the porous medium. plastic deformation of the porous medium.(2) where EP is the plastic strain tensor and K and the work-hardening parameter. From the equation of motion for the fluid, the interaction force P can be expressed in the form(3) where is the inertial force of the fluid per unit volume of the mixture and F is the body force acting on the fluid per unit volume of fluid. For the case of incipient plastic deformation the solid can be considered static (velocities of the solid particles are zero), and the problem of determining particles are zero), and the problem of determining the fluid flow field is the one usually analyzed in petroleum engineering. petroleum engineering. Consider a flow of be fluid such that the inertial forces of the fluid can be neglected and assume that Darcy's law is applicable. SPEJ P. 271

The aim of the present study was to determine the dietary habits and nutritional status of workers in a dairy company in northern Ecuador. Observational, descriptive and transversal research, which used the survey through a questionnaire with sociodemographic and anthropometric variables to determine the nutritional status; and, the frequency of consumption to identify eating habits. The results report a preponderance of the masculine sex and mestizo ethnicity among the workers, with an age range between 30 and 60 years. Regarding the nutritional status, according to the Body Mass Index, 56.0% of workers are overweight, 8.2% Obesity level I, and 0.5% Obesity level II. In the Waist Circumference according to sex, it was found that in women (82-88 cm) there is a high risk in 32.7%; very high risk (> 88 cm) and 26.5%; in men 13.5% high risk (95-102 cm) and 5.3% very high risk (> 102 cm). In terms of eating habits, according to the frequency of consumption survey, 78.0% consume 3 to 4 meal times; being the less consumed refreshments, the foods that ingest the most are rice, potatoes, bread, sugar, eggs and dairy with frequent daily consumption and the less consumed are fruits, vegetables and legumes with a frequency of 1 week consumption. It is concluded that body mass index and waist circumference increase in relation to the advance of age and eating habits due to excess and nutritional imbalance.
