background nasal septal deviation (nsd) can cause upper airway obstruction, which results in hypoxia and therefore, pulmonary vasoconstriction, ventricular hypertrophy and right-sided heart failure. objectives the aim of this study is to determine the mean pulmonary arterial pressure (mpap) of the patients with nsd and the effect of septoplasty on pulmonary arterial pressure. patients and metho...

The process of population ageing that is occurring in developed societies represents a major challenge for the health system. Cardiovascular diseases (CVD) are the most common cause of morbidity and mortality in the world, representing half of the deaths in people over 65 years old. Among the CVD, systemic arterial hypertension is related to more than half of those outcomes [1]. The non-modifia...

Subclavian Artery Thrombosis (SAT) typically arises secondary to some form of injuries and arthrosclerosis. The contributing factors are coagulopathies and emboli. And, the conserving blood is naturally reflowed from circle of Willis. A cold, painful, cyanosis, and pulseless upper extremity are proved as the symptoms. Recently, a 42-years-old smoker, diabetic, and hyperlipidemic woman was admit...

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...

A high performance numerical technique in the study of aorto-coronaric bypass anastomoses configurations using steady Stokes equations is presented. The problem is first expressed as an optimal control problem. Then, by using an embedding method, the class of admissible shapes is replaced by a class of positive Borel measures. The optimization problem in measure space is then approximated by ...

o bjective: to determine the etiology, signs and symptoms, angiography indications and angiography findings in patients with limb penetrating injuries suspected to have arterial injury. m e thods: this was a cross-sectional study being performed in imam reza hospital affiliated with mashhad university of medical sciences, iran between september 2011 and march 2013. we included those patients wi...

background: patients undergone mechanical ventilation need rapid and reliable evaluation of their respiratory status. monitoring of end-tidal carbon dioxide (etco2) as a surrogate, noninvasive measurement of arterial carbon dioxide (paco2) is one of the methods used for this purpose in intubated patients. objectives: the aim of the present trial was to study the relationship between end-tidal c...

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:  One ofdiagnostic criteria for Acute Lung Injury and Acute Respiratory Distress Syndrome is  pao2/fio2 (PF) ratio 300 for ALI or 200 for ARDS. This criteria requires invasive arterial sampling. Measurement of Spo2/Fio2 (SF) ratio by pulseoximetry may be a reliable non invasive alternative to the PF ratio.   Methods and Materials: In a cross sectional study we enrolled 105 sample o...
