There are two methods for evacuating a submarine
Escape
Rescue

Submarine rescue – unpredictable, mass casualty situation in a hostile environment with resource constraints
Considerations Trauma
(orthopaedic/burns/internal injuries)
Respiratory compromise
Decompression Sickness
Barotrauma (CAGE)
Hypothermia
Petrochemical contamination
Radiation exposure
Recompression Chamber Space
Oxygen supplies
Number of Survivors (reverse triage)
Retrieval – aeromedical evacuation
Iatrogenic Decompression Sickness in rescue personnel.
Surface weather conditions

Decompression Sickness
DCS classified in three types
Type I – mild, typically affecting muscloskeletal, cutaneous and lymphatic systems.
Type II – severe, typically affecting neurological system. Of the neurological cases, approximately 5 % may manifest pulmonary manifestations ‘the Chokes.’ This can lead to right sided heart failure, circulatory collapse and death.
Cerebral Arterial Gas Embolism (CAGE) – usually stemming from high venous gas loads (with patent foramen ovale) or pulmonary barotrauma with gas entraining into arterial circulation.
