"If there is an obvious cause of the hypotension, such as trauma or a GI bleed, you don’t need this approach. Just start treatment as usual.
Control the airway and supply oxygen. Most times this will be with basic airways maneuvers or an LMA. You can always intubate later when you have the patient better resuscitated."

"A good approach when dealing with hypotension at the bedside includes using the following systematic four step evaluation, which relies heavily on our bedside physical examination and ultrasound skills to evaluate each individual component:
- Heart Rate
- Volume Status
- Cardiac Performance
- Systemic Vascular Resistance
In general, hypotension results from a dysfunction in one or more of these components, so systematically going through these components and addressing them one at a time is a great way to understand the underlying disease pathophysiology our hypotensive ED patient faces."
