Diagnostic accuracy of biomarkers in acute mesenteric Ischemia

A 79 years old man presents to the Emergency Department with acute onset of central abdominal pain and one attack of bloody diarrhoea. The pain is severe and not relieved by simple analgesia.

Should Non-Invasive Ventilation be used as the first-line method of pre-oxygenation in a non-obese patient presenting with a hypoxia and needing intubation in the Emergency Department in order to prevent desaturation?

A non-obese 68-year-old man is brought to the emergency department by his family with a history of progressive dyspnea over the last week; he has both a productive cough and a fever. He’s very confused and non-combative. His initial saturation is 84% with a reservoir oxygen mask; he is tachypneic with a respiratory rate of 35. You decide to intubate this patient and you need to optimize his saturation before induction. One of your colleagues suggests that you should try Continuous Positive Airway Pressure (CPAP) prior to intubating him. You have not yet used this technique in similar situation. You wonder if CPAP should be used as a means of optimizing oxygenation in non-obese patients with hypoxia before intubation.
