Contributor: Don Stader, MD Educational Pearls: Pain is ubiquitous in the emergency department but it is not the enemy - suffering is Nociception is the ability to feel noxious stimuli which usually causes a reaction, like pulling a limb away when you feel something painful. Nociception is really a brainstem reflex. Pain is nociception plus cognition, meaning we process the noxious stimuli in our frontal cortex but it is not necessarily suffering. Pain can be associated with euphoria, such as wi...

Contributor: Aaron Lessen, MD Educational Pearls: The use of oxygen is controversial when treating patients with certain conditions, like MI's, stokes, or ARDS because adverse outcomes have been demonstrated with using high oxygen concentrations. The Oxygen ICU trial looked at using higher and lower oxygen levels in treating intubated ARDS patients and found that mortality was improved when less oxygen was given allowing oxygen saturations to sit around 95% versus using high oxygen levels to obt...

Contributor: Peter Bakes, MD Educational Pearls: Classically presents with the 6Ps: Pain, pallor, paresthesia, pulseless, poikilothermia (cold), and paralysis Acute limb ischemia occurs by embolic or thrombotic causes Thrombotic causes are now more common due to aging populations and advancements in vascular surgery like stents which can be a nidus for thrombosis. Sudden onset of pain without prior symptoms is more typical of embolic causes Preceding symptoms leading to acute ischemia are more o...

Capnography is the measurement of the partial pressure of exhaled CO2 and is an indirect measurement of your cellular respiration. It is displayed visually as a block-like waveform during the exhalation phase of respiration and monitors ventilation in real-time. Capnography is the gold standard for monitoring sedated and intubated patients in the hospital and the field and can be used in many other situations to discern more information about your patient. Our host Jordan Ourada is joined by Dr....
