🚨 Emergency Department (ED)
🩺 What Is the Emergency Department?
The Emergency Department (ED) — also called Casualty — is the specialized hospital unit that provides immediate and life-saving care for patients with sudden, severe, or life-threatening conditions.
It operates 24×7 and is staffed with emergency physicians, nurses, and trauma specialists trained to rapidly assess, stabilize, and treat patients in critical situations.
Emergency medicine covers all age groups and all organ systems — from trauma and cardiac arrest to infections and poisoning — serving as the first line of defense in saving lives.

💊 Medical Treatment in the ED
Triage: Sorting patients by urgency (red – critical, yellow – serious, green – mild).
Immediate Stabilization:
Airway clearance, oxygen supply, or intubation.
IV fluids for dehydration or shock.
Defibrillation or CPR for cardiac arrest.
Diagnostic Evaluation: ECG, X-rays, CT scans, blood tests.
Definitive Treatment: Medication, wound care, surgery, or admission to ICU.
Monitoring: Continuous observation until the patient is stable.
🏠 Home & Lifestyle Measures After Emergency Recovery
Get adequate rest and hydration.
Follow doctor’s prescription and physiotherapy (if any).
Eat balanced meals rich in protein and vitamins for healing.
Avoid smoking, alcohol, or heavy exertion.
Schedule follow-up appointments for long-term recovery.
⚠️ Complications If Emergency Care Is Delayed
| Condition | Possible Consequence |
| Heart attack | Cardiac arrest or death |
| Stroke | Permanent paralysis |
| Severe bleeding | Shock or organ failure |
