Abstract
The following initial measures apply to all stroke patients. They are necessary to stabilize and assess the patient, and prepare for definitive therapy. All current and, probably, future stroke therapies for both ischemic and hemorrhagic stroke are best implemented as fast as possible, so these things need to be done quickly. This is the general order to do things, but in reality, in order to speed the process, these measures are usually dealt with simultaneously. They are best addressed in the ED, where urgent care pathways for stroke should be established and part of the routine (see Chapter 14).

Airway – Breathing – Circulation (ABCs)
Oxygen saturation and O2 via nasal cannula. Routine oxygen delivery in acute stroke patients has not been shown to improve outcome. But it is commonly routinely employed, since oxygen desaturation frequently occurs due to pre-existing lung disease, obtundation, acute aspiration, etc.
Intubation may be necessary if the patient shows arterial oxygen desaturation or cannot “protect” his or her airway from aspirating secretions. However, intubation means that the ability to monitor the neurological exam is lost. The best approach in such patients is to prepare to intubate immediately, but before doing so, take a moment to be sure the patient does not spontaneously improve or stabilize with good nursing care (suctioning, head position, etc.). Also, if needed, use sedating or paralyzing drugs with a short half-life, to allow for serial neurological exams.
Consider putting the head of the bed flat. This can significantly help cerebral perfusion. The head of the bed may need to be elevated if airway protection and continued nausea and vomiting are concerns for those with obtundation, nausea, severe dysphagia, or aspiration risk.
Consider normal saline bolus 250–500 mL if blood pressure is low.
If the blood pressure is high, antihypertensive treatment is discussed in subsequent chapters (Chapters 3, 5, 6, 7, 8, and 12).
