Are arterial blood gases necessary in the evaluation of acutely dyspneic patients?

چکیده
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 peripheral venous and ABG, we will continue to advocate the use of ABG in the evaluation of acute dyspnea.

Background: Measuring End-Tidal Carbon Dioxide (ETCO-2) can be a non-invasive, fast, and reliable method to predict partial pressure of carbon dioxide (PaCO2) in patients with respiratory distress. This method, which can be a suitable substitute to measure PaCO2, is being used in many emergency rooms and operating rooms in developed countries, but its exact relationship with PaCO2 has not been ...

Background & Aim : Endotracheal suctioning is one of the most frequently used methods for airway clearance in patients under mechanical ventilation. Chest physiotherapy techniques such as expiratory rib cage compression before endotracheal suctioning can be used as a means to facilitate mobilizing and removing airway secretions and improving alveolar ventilation. This study was carried out to...

Background and Objectives: Suction is a necessary and common method which aids in the release of secretion from the respiratory system for the patients who have undergone mechanical ventilation. One of the most common complications of suction is hypoxemia which causes dysrhythmia and death. The purpose of this study was to determine the effects of open and closed-endotracheal suction on cardiov...
