Oxygen is an essential part of the most important metabolic pathways in aerobic organisms. Oxygen delivery is merely dependent on blood, rendering blood loss a devastating event. Traumatic pre-hospital liver bleeding is a major cause of early trauma deaths in human and animals, with no established therapeutic method yet. Increasing intra-abdominal pressure (IAP) has been shown to reduce liver b...

arterial blood gas parameters were analyzed in forty-nine healthy persons (31 males, 18 females) to detemine reference values fo these parameters and their relation to the time from last food intake to arterial puncture (t). the mean ± standard deviation of arterial oxygen pressure, arterial carbon dioxide pressure and ph at core body temperature were 84.4±7.0 mmhg (male: 83.0±6.5, female: 86.7...

introduction: arterial gas derangement could change urinary sodium excretion in chronic obstructive pulmonary disease (copd) patients.there are very few and conflicting data in regards to the measurement of fractional excretion of sodium in copd patients. the main aim of this study was to assess the relationship between renal fractional excretion of sodium(fena) with arterial blood gas and spir...

background : mechanical ventilation is used for some infants in neonatal intensive care units (nicu) due to many physiological and clinical causes. since these patients have endotracheal tubes, cleaning and keeping the airways open through suctioning should be done to increase oxygenation. this study aimed to evaluate effect of open and closed suctioning methods on respiratory parameters of inf...

Arterial blood gas (ABG) sampling is a painful procedure with no perfect technique for quelling the discomfort. An ideal local anesthesia should be rapid, easy to learn, inexpensive, and noninvasive. This study was aimed to compare pain levels from ABG sampling performed with vapocoolant spray in comparison to placebo. We hypothesized that pretreatment with the vapocoolant would reduce the pain...

Aims: The present study was conducted with the aim of determining the effect of passive movements on hemodynamic parameters, including systolic blood pressure, diastolic blood pressure, mean arterial pressure, pulse, and pulse pressure of patients under ventilation. Materials & Method: In this controlled clinical trial, 64 patients under ventilation in Kohgiluyeh and Boyer-Ahmad University of ...

We evaluated whether the increase in blood lactate with intense exercise is influenced by a low hepatosplanchnic blood flow as assessed by indocyanine green dye elimination and blood sampling from an artery and the hepatic vein in eight men. The hepatosplanchnic blood flow decreased from a resting value of 1.6 +/- 0.1 to 0.7 +/- 0.1 (SE) l/min during exercise. Yet the hepatosplanchnic O2 uptake...

In multiple fields of study, access to the circulatory system in laboratory studies is necessary. Pharmacological studies in rats using chronically implanted catheters permit a researcher to effectively and humanely administer substances, perform repeated blood sampling and assists in conscious direct measurements of blood pressure and heart rate. Once the catheter is implanted long-term sampli...

OBJECTIVE To identify the relevant differences between portable blood glucose meter readings in different sampling accesses blood and laboratory analysis. METHODS Quantitative validity study. Daily samples were collected from capillary blood, central venous access catheter and arterial catheter and the blood glucose values checked using portable blood glucose meter and laboratory analysis. Th...
