introduction: one of the main complications of hemodialysis in patients with chronic renal failure is hypoxemia which is related to several factors including the type of filter. the aim of this study was to evaluate the hypoxemia levels in patients undergoing hemodialysis with focus on the type of filter. methods: in a crossover clinical trial, 29 patients from emodialysis ward of fatemieh hosp...

background pulse-oximetry (spo2) widely uses as a help tools for therapeutic interventions in the pediatric intensive care units (picu). the aim of this study was to evaluate the validity of spo2 in measuring of oxygenation index (oi) in children. materials and methods in a descriptive analytical study, 100 patients who were admitted to picu tabriz children's hospital were studied. oxygena...

BACKGROUND Although recommendations in oxygenation and gas exchange monitoring in the neonatal intensive care unit (NICU) are available, little is known of the current practice. AIM To evaluate the current practice in oxygenation and gas exchange monitoring of the NICUs in the Netherlands. METHODS An online survey-based questionnaire concerning preferences and current practice of monitoring...

aim and background: remote ischemic preconditioning introduces brief episodes of ischemia and reperfusion which reduces long term ischemia in orthopaedic surgery. the aim of this study was to evaluate hemodynamic and respiratory effects of remote ischemic preconditioning in lower extremity orthopaedic surgeries. methods: in this clinical trial 40 patients scheduled for lower extremity surgery w...

Continual improvement of oxygenators has been important in the growing demands of patient safety and support during cardiopulmonary bypass. The purpose of this study was to compare the Maxima 1380 oxygenator to the upgraded Maxima Plus oxygenator. Thirty-two adult patients were randomized to either the 1380 group or the Plus group. Information was recorded on the patients' weight, age, body sur...

The effects of sevoflurane or isoflurane on arterial blood gas, arterial oxyhaemoglobin saturation and end-tidal CO2 tension were monitored during induction and maintenance of anaesthesia in 10 premedicated New Zealand White (NZW) rabbits.For induction, the anaesthetic agents were delivered via a face-mask. After induction was completed, an endotracheal tube was introduced for maintenance of an...

Case 1: A 24 year-old woman is found down in Pioneer Square by some bystanders. The medics are called and, upon arrival, find her with an oxygen saturation of 88% on room air and pinpoint pupils on exam. She is brought into the Harborview ER where a room air arterial blood gas is performed and reveals: pH 7.25, PCO2 60, PO2 65, HCO3 26, Base Excess 1. On his chemistry panel, her sodium is 137, ...

Arterial blood gas (ABG) interpretation can be a difficult and daunting concept for students and new critical care nurses to grasp. Although ABG interpretation can be arduous, it is essential that critical care nurses master this skill, because accurate interpretation can be life determining. Fortunately, with the numerous technological advances that are available, ABG interpretation can be les...

neonates with respiratory distress syndrome (rds), who are treated according to insure protocol; require arterial blood gas (abg) analysis to decide on appropriate management. we conducted this study to investigate the validity of pulse oximetry instead of frequent abg analysis in the evaluation of these patients. from a total of 193 blood samples obtained from 30 neonates <1500 grams with rds,...

BACKGROUND Coexisting cardiorespiratory disease may contribute in individual cases to the increased ventilatory response to exercise in patients with chronic heart failure. OBJECTIVE To characterise further the arterial blood gas response to exercise and to explore the possible uses of blood gas sampling in clinical practice in patients with chronic heart failure. METHODS 37 patients with a...
