BACKGROUND Pulse oximetry is routinely used to continuously and noninvasively monitor arterial oxygen saturation (SaO2) in critically ill patients. Although pulse oximeter oxygen saturation (SpO2) has been studied in several patient populations, including the critically ill, its accuracy has never been studied in emergency department (ED) patients with severe sepsis and septic shock. Sepsis res...

To establish guidelines for the interpretation of changes in arterial blood gas (ABG) values, we studied 29 clinically stable ICU patients for spontaneous variability in PaO2, PaCO2 and pH. ABGs were sampled six times over a 50-minute period, during which all patients received a fixed FIO2 of 0.5 via endotracheal tube and underwent no therapeutic interventions. Each sample was analyzed in dupli...

As the cases of kidney transplant are increasing, the need to apply the factors to increase the success of transplant seems necessary. Mannitol increases the osmotic pressure and urine volume as a protective agent on renal tubules. We aimed to evaluate the effect of mannitol on short-term outcome of kidney transplantation by comparing two groups based on prescribing mannitol to donors. In a ran...

INTRODUCTION Glucose control to prevent both hyperglycemia and hypoglycemia is important in an intensive care unit. Arterial blood gas analyzers and glucose meters are commonly used to measure blood-glucose concentration in an intensive care unit; however, their accuracies are still unclear. METHODS We performed a systematic literature search (January 1, 2001, to August 31, 2012) to find clin...

STUDY OBJECTIVES Bilevel pressure ventilation has had proven success in the treatment of acute respiratory failure (ARF). The purpose of this study was to identify patient characteristics early in the course of acute illness that can predict the successful use of bilevel pressure ventilation. METHODS Ventilatory assistance using a ventilatory support system (BiPAP model ST-D; Respironics; Mur...

CAN J ANESTH 55: 2 www.cja-jca.org February, 2008 A 60-yr-old lady with HbM Saskatoon and congenital methemoglobinemia was scheduled for mastectomy. Clinical examination confirmed cyanosis but she had no symptoms due to methemoglobinemia and no history suggestive of cardiac or respiratory problems. Her electrocardiogram was normal and arterial blood gas (ABG) values on room air were: pH = 7.52,...

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/ bcr-2014-204087 DESCRIPTION Pulmonary arteriovenous malformation (PAVM) is caused by the abnormal connection between pulmonary arteries and venous systems. First described in 1897 by Churton, PAVM is a rare disease. In an autopsy study in 1953 at Johns Hopkins, only 3 cases...
