The document discusses different types of crises. A crisis in medicine refers to a point of decision where failure to act appropriately and timely could result in a patient's death. Crises can be regular situations that require a plan to mitigate impacts, or they can be sudden with no warning signs, requiring immediate action. Some crises are predictable and detectable early on, allowing time to recover the situation. Managing crises requires key experts, tools, and partners working together.
