Introduction: Coronary artery disease secondary to atherosclerosis is the most common cause of mortality. Coronary angiography is the most precise method for determining the extent of disease in the coronary vascular bed. Arterial stiffness has been proposed as a marker of atherosclerosis in some studies. One of the noninvasive methods for the determination of arterial stiffness is Doppler echo...

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...

introduction anabolic-androgenic steroids (aas), a synthetic derivate of testosterone, have become a popular drug among athletes and bodybuilders to enhance muscle mass and improve the athletic performance. many pathological effects such as hepatic and endocrine dysfunction, behavioural changes and cardiovascular complications have been reported. case report within these ast ones, we find an in...

Background: Arterial pressure is one of the most important physiological variables and often needs to be monitored repeatedly or continuously in perioperative period. Arterial pressure monitoring is one of the standard monitoring in operating room. During general anesthesia, blood pressure can be measured by using a noninvasive arterial pressure method or continuous invasive arterial pressure b...

Diastolic phase of cardiac function is associated with lower arterial flow and hence higher concentration of intra arterially injected drug is achieved at the site of injection. It is herein postulated that drugs show higher efficacy when injected during the diastolic phase of cardiac function. It is also postulated that this benefit cannot be achieved when the drug is injected with higher rate...

background: pulse wave velocity (pwv) is widely used for estimating the stiffness of an artery. v arious invasive and non-invasive methods have been developed to determine pwv over the years. in the present research , the non-invasive estimation of the pwv of large arteries was used as an index for arterial stiffness. methods: a dynamic model based on the navier-stokes equations coupled to elas...

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...

abstract background: stressors in the intensive care unit (icu) impair patients’ comfort, excite the stress response, and increase oxygen consumption in their body. non‑medical interventions are recommended by several studies as a treatment to improve comfort in the icu patients. sensory stimulation is one of the most important interventions. since arterial blood oxygen saturation is an importa...

Background and Objectives: Suction is a necessary and common method which aids in the release of secretion from the respiratory system for the patients who have undergone mechanical ventilation. One of the most common complications of suction is hypoxemia which causes dysrhythmia and death. The purpose of this study was to determine the effects of open and closed-endotracheal suction on cardiov...
