the acid-base status and arterial blood gas change with temperature variation. to determine the changes in arterial ph and pc02, arterial blood samples of 50 neonates with different clinical conditions were examined at temperatures of 35 to 42°c with an increment of 0.5° c, which resulted in two nonlinear equations with perfect fit on data. the temperature correction factors of these equations,...
Background & Objective : Several indices have been introduced to estimate arterial stiffness that based on changes in brachial blood pressure. But because of the error resulted by the substitution of brachial blood pressure instead of the other central arteries, such as carotid, it will be very important to present elastic parameter based on the mechanical models without any emphasis on brach...
Background and purpose : Arterial blood gases ( Arterial blood gas [ABG] ) One of the most important Laboratory tests to determine the status PH the amount of oxygen and carbon dioxide blood levels of bicarbonate. Also, hemoglobin and serum lactate and electrolytes and also won the Test . Height and air pressure can vary on ABG and its surface, low pressure conditions at high altitude pilots pl...
introduction: arterial stiffness is an important predictor of cardiovascular risk. several indices have been introduced to estimate the arterial stiffness based on the changes in the brachial blood pressure. since the substitution of the blood pressure changes in the central arteries such as carotid with the blood pressure changes in the brachial results in error in the blood...

The removal and eventual disposal of adsorbed and absorbed gasses from solid or semi-porous surfaces requires the detachment and diffusion of the gasses. To facilitate the process, the method described here uses the heretofore undescribed product Air Depleted Water (ADW), although the process can be applied to other liquids. By removing the dissolved air gasses, a maximum concentration gradient...
Background: Previous studies demonstrated a health improving effect in patients underwent an automatic vibratory massage taking 10 minutes. One of reasons that may explain a healing effect of the automatic massage is a stimulated increase in both blood circulation through vascular system and effective size of blood vessels. Objective: This paper aims to quantify a contribution of the auto...
In an earlier neonatal porcine model of smoke inhalation injury (SII), immediate postinjury application of partial liquid ventilation (PLV) had dramatic beneficial effects on lung compliance, oxygenation, and survival over a 24-h period. To explore the efficacy of PLV following SII, we treated animals at 2 and 6 h after SII and followed them for 72 h. Pigs weighing 8-12 kg were sedated and phar...
Aim and Background: Now, 95 % of the pregnant experience regional anesthesia. Neuro-axial technique-induced sympathic block may result in hypotension in the mothers and consequently can affect the blood uterus. Different findings regarding the effects of prophylactic hydration prevention of maternal hypotension , the decision to study in this field. Materials and Methods: The study is a randomi...
