Medical emergency

A medical emergency is an acute illness or injury requiring immediate assessment or treatment to prevent death, serious harm, or lasting disability.

Triage: Triage is the process of sorting patients by urgency and directing them to appropriate care. It prioritizes treatment when several patients need attention or resources are limited.
Stroke: A stroke is brain injury caused by interrupted blood flow or bleeding in the brain. Sudden neurological symptoms can signal a time-critical emergency requiring rapid evaluation.
Urgent care: Urgent care provides prompt treatment for problems that need attention soon but are not life-threatening emergencies. It is an alternative setting when immediate resuscitation or hospital-level care is not needed.
Cardiac arrest: Cardiac arrest is the sudden loss of effective heart pumping and circulation. It is an immediate emergency in which delays in resuscitation can be fatal.
ABCDE approach: The ABCDE approach assesses airway, breathing, circulation, disability, and exposure in that order. It gives clinicians a systematic way to identify and address immediate threats.
Myocardial infarction: A myocardial infarction is death of heart muscle caused by inadequate blood supply. Prompt treatment can limit heart damage and reduce the risk of death.
Elective surgery: Elective surgery is planned surgery that can be scheduled in advance rather than performed immediately. Its timing contrasts with interventions that cannot safely wait.
Emergency department overcrowding: Emergency department overcrowding occurs when demand exceeds a department's capacity to provide timely care. Crowding can delay assessment and treatment for time-sensitive emergencies.
Emergency medical services: Emergency medical services provide urgent assessment, treatment, and transport before hospital care. They can begin stabilization and coordinate transport to an appropriate facility.
Sepsis: Sepsis is life-threatening organ dysfunction caused by a dysregulated response to infection. It can progress rapidly and requires urgent recognition and treatment.
