BACKGROUND Assessing the ventilatory status of non-intubated infants in the Pediatric Intensive Care Unit (PICU) is a constant challenge. Methods to evaluate ventilation include arterial blood gas analysis (ABG), which is invasive and intermittent, and transcutaneous carbon dioxide monitoring (PtcCO2), which, while non-invasive, is also intermittent. A method that is non-invasive and continuous...

Background: Bullous emphysema is characterized by destruction of lung parenchyma, reduction in elasticity of the lung, hyperinflation, and ventilation/perfusion mismatch. Ventilatory management of the patient with bullous emphysema is challenging, and especially so for the patient undergoing cardiac surgery. Case report: A 47-yearold man with severe diffuse bullous emphysema requested general a...

BACKGROUND: Diabetic ketoacidosis (DKA) is a life-threatening endocrine emergency, traditionally requiring arterial blood gas (ABG) analysis for diagnosis and monitoring. The aim of our study was to assess the comparability of arterial and venous blood samples for pH and bicarbonate measurements in patients with DKA. MATERIALS AND METHODS: Prospective, observational study of patients with suspe...

Arterial blood gases (ABG) are obtained commonly in dyspneic persons presenting to emergency departments. The study by Burri and colleagues found that the information contained in ABG fails to distinguish between pulmonary and other causes of dyspnea. On the other hand, arterial pH was highly predictive of ICU admission and outcome. Until large clinical studies show equivalence between peripher...

conclusions: in the present study, applying positive airway pressure methods (cpap or imv) during cpb was associated with better postoperative abg measurements and (a-a) do2. results: the demographic data were similar in between three groups. graft number, pump time and preoperative abgs were not significantly different. postoperative pao2 were significantly higher in the cpap and imv groups an...

BACKGROUND Liver transplant is the only definitive treatment for many patients with end stage liver disease. Presence and severity of preoperative pulmonary disease directly affect the rate of postoperative complications of the liver transplantation. Arterial blood gas (ABG) measurement, performed in many transplant centers, is considered as a traditional method to diagnose hypoxemia. Because A...

BACKGROUND On-pump coronary artery bypass graft (CABG) surgery impairs gas exchange in the early postoperative period. The main object on this study was evaluation of changes in arterial blood gas values in patients underwent on pump CABG surgery receiving different dose of intravenous nitroglycerin (NTG). MATERIALS AND METHODS sixty-seven consecutive patients undergoing elective on-pump CABG...

INTRODUCTION Metabolic acidosis confirmed by arterial blood gas (ABG) analysis is one of the diagnostic criteria for diabetic ketoacidosis (DKA). Given the direct relationship between end-tidal carbon dioxide (ETCO2), arterial carbon dioxide (PaCO2), and metabolic acidosis, measuring ETCO2 may serve as a surrogate for ABG in the assessment of possible DKA. The current study focuses on the predi...
