Blood pressure is one of the vital signs. Specially, it is crucial for some cases such as hypertension patients and it should be monitored continuously in ICU/CCU. It must be noted that current systems to measure blood pressure, often require trained operators. As an example, in post-hospital cares, blood pressure control is difficult except with the presence of a nurse or use of a device that ...
Introduction: In hypertensive patients M position (sitting, right arm at the level of heart and both plantar surface of foots on the floor) is the standard position for measurment of blood pressure since it reveals the “true” pressure. Materials and Methods: It is a quaziexperimental study that compares effect of different positions of limbs on blood pressure of hypertensive patients. The sampl...
Background & objectives: Cardiopulmonary bypass often causes a stress hormonal response with subsequent changes in hemodynamic and organ perfusion. Human studies involving cardiopulmonary bypass have shown that very low doses of ketamine can attenuate inflammatory and stress markers, without adverse effects. The aim of this study was to investigate whether low dose infusion of ketamine have hem...
Accurate continuous direct measurement of the blood pressure is currently available thru direct invasive methods via intravascular needles, and is mostly limited to use during surgical procedures or in the intensive care unit (ICU). Non-invasive methods that are mostly based on auscultation or cuff oscillometric principles do provide relatively accurate measurement of blood pressure. However, t...
High-precision measurement of the resistance of nickel near its ferromagnetic phase transition at high pressure was done in a large volume hydrostatic cubic multiple-anvil pressure cell between 25 and 45 kbar. A real-tine computer-controlled measurement system was developed to measure the resistance vs temperature and pressure. The values of the critical exponent a and amplitude ratio of the le...
OBJECTIVES To compare the agreement between conventional measurement of blood pressure and measurements obtained using two automated devices; and to compare how comfortable each of the three methods of measurement were for patients. METHODS Blood pressure measurements and patient comfort scores were recorded using three different devices in 125-surgery and 40-community patients. The devices u...
