Dementia criteria
One or more of:
- Aphasia - impaired ability to communicate
- Apraxia - can explain but cannot act out a movement of an already learned activity
- Agnosia - inability to recognize previously known objects
Schizophrenia
Significant change in behaviour and loss of contact with reality
Key features of excited delirium (AHS protocol)
- Drug abuse or psych hx
- Hyperthermia
- Inappropriate clothing removal
- Violent/bizarre behaviour
- Insensitivity to pain
- Unexpected physical strength
- Constant/near constant physical activity
- Shouting/unintelligible noises
Three phases of activity preceding death from restraint asphyxia
- Preintervention phase - patient demonstrates signs of excited delirium
- Intervention initiation phase - EMS/police respond and recognize need for restraint; a chase or struggle ensues and the patient uses large amounts of energy
- Continued struggle phase - patient is restrained but continues to exert energy to escape, and will struggle to breath if prone; risk of respiratory and cardiac arrest
