We have searched to define the major arterial parameters that determine aortic systolic (Ps) and diastolic (Pd) pressure in the dog. Measured aortic flows were used as input to the 2-element windkessel model of the arterial system, with peripheral resistance calculated as mean pressure divided by mean flow and total arterial compliance calculated from the decay time in diastole. The windkessel ...

BACKGROUND The objective of this study was to examine the correlation between arterial blood gas (ABG) and peripheral venous blood gas (VBG) samples for all commonly used parameters in patients admitted to a medical intensive care unit (ICU). METHODS A single-center, prospective trial was carried out in a medical ICU in order to determine the level of correlation of ABG and peripheral VBG mea...

Whether arterial conduits are superior to venous grafts in coronary artery bypassing has been debated. The aim of this study was to investigate clinical outcomes after total arterial revascularization versus conventional coronary bypassing using both arterial and venous conduits in isolated three-vessel coronary disease. Between 2003 and 2005, 503 patients who underwent isolated coronary artery...

background: to study the effect of oral garlic on arterial oxygen pressure in children with hepatopulmonary syndrome. materials and methods: garlic powder in a capsule form was given to 15 children with hepatopulmonary syndrome (confirmed by contrast echocardiography) at the dosage of 1 g/1.73 m2 per day. patients were evaluated clinically and by arterial blood gas every four weeks. results: th...

introduction: world health organization (who) introduced hypertension as an epidemic in developing countries. however, hypertension is adequately controlled in only 12.5% of patients.  the aim of this study was to evaluate the relationship between ramadan fasting and mean arterial pressure (map). methods: this clinical, observational study was carried out at medical o.p.d of jinnah medical coll...

conclusions ipah is associated with subclinical hypothyroidism and low patient functional capacity, and is more common in rv failure. results in this research, 84.8% of the participants were women. the mean pap was 51.6 mmhg (31-87) and mean thyroid stimulating hormone (tsh) level was 4.2 miu/ml (0.7 - 10). subclinical hypothyroidism was detected in 26 patients (49.1%). there were significant c...

Aim of this randomized study (64 patients) was to improve the control of bleeding during functional endoscopic sinusal surgery by means of controlled hypotension achieved through either total intravenous anaesthesia using remifentanyl and propofol (27 patients), or inhaled using isoflurane and fentanyl (37 patients). The following parameters were monitored before administration of anaesthesia (...

Bus travel time on road section is defined and analyzed with the effect of multiple bus lines. An analytical model is formulated to calculate the total red time a bus encounters when travelling along the arterial. Genetic algorithm is used to optimize the offset scheme of traffic signals to minimize the total red time that all bus lines encounter in two directions of the arterial. The model and...

spherical equivalent (se) has not been linked to increased cardiovascular morbidity. methods: 132 hungarian twins (age 43.3±16.9 years) underwent refraction measurements (huvitz mrk-3100 premium autorefractokeratometer) and oscillometry (tensiomed arteriograph). results: heritability analysis indicated major role for genetic components in the presence of right and left se (82.7%, 95%ci, 62.9 to...
