• EEG monitoring
• Brainstem function tests

Treatment Approaches

1. Immediate Interventions

   • Stabilizing blood pressure

2. Ongoing Care

   • Nutrition support
   • Infection prevention
   • Physical therapy
   • Monitoring vital signs

Recovery and Prognosis

• Recovery time varies significantly
• Outcome depends on:
  • Cause of coma
  • Duration
  • Age and overall health
  • Quality of care

Long-term Care

• Rehabilitation services
• Physical therapy
• Occupational therapy
• Speech therapy
• Family support and counseling
