Emergency Evacuation Plan for Type 2 Neurological DCS in the Bahamas

Here’s a tailored emergency evacuation plan for a Type 2 neurological decompression sickness (DCS) incident occurring in the Bahamas. This plan accounts for the specific challenges of the region—remote islands, limited hyperbaric facilities, and logistical hurdles—while incorporating insurance realities (e.g., DAN Guardian or DiveAssure Platinum) as of March 16, 2025. Type 2 DCS involves severe neurological symptoms (e.g., paralysis, numbness, confusion), requiring urgent evacuation to a recompression chamber. This plan assumes you’re diving in a relatively remote area like the Exumas, with factors like human delays, paperwork, and communication breakdowns considered.

Scenario: You’re diving at 100 ft in the Exumas, Bahamas, on a liveaboard. After a rapid ascent (skipping a safety stop), you surface with leg numbness, confusion, and arm weakness—classic Type 2 neurological DCS. The nearest hyperbaric chamber is in Nassau (150 miles away), and immediate evacuation is critical to prevent permanent damage. Here’s your step-by-step plan, factoring in delays and why you need cash despite direct payment insurance (e.g., DAN Guardian).

Key Assumptions

Location: Exumas, Bahamas—remote, 150 miles from Nassau’s chamber at Doctors Hospital.
Symptoms: Type 2 DCS—neurological (numbness, weakness, confusion)—time-sensitive, needing recompression within hours.
Insurance: DAN Guardian ($500,000 coverage, 15–60 min approval) or DiveAssure Platinum ($500,000, 20–60 min approval).
Challenges: Human delays, remote logistics, communication issues, paperwork, out-of-network providers, red tape, insurer bottlenecks.

Step-by-Step Evacuation Plan

Step 1: Immediate On-Site Response (0–15 Minutes)

Action:
- Signal for Help: Alert your dive buddy and crew—surface signal (e.g., wave, whistle) if separated.
- Administer Oxygen: Get 100% O₂ via demand mask (15 L/min) from the boat’s emergency kit—slows DCS progression.
- Stabilize: Lie flat, avoid exertion—reduces bubble spread.
Human Factor Risk: Panicked buddy delays O₂ or forgets protocol—adds 10–15 minutes.
Why Pay?: Boat crew may demand $200–$500 for O₂ kit use if not pre-arranged—cash speeds access.
Prep: Have $500 cash—covers immediate needs.

Step 2: Contact Local EMS (15–30 Minutes)

Action:
- Call Bahamas EMS: Dial 911 or VHF Channel 16 (Coast Guard)—request medical evacuation for DCS. Provide location (e.g., Exumas, 24°10’N, 76°20’W), symptoms, and urgency.
- Boat Transport: If EMS is slow, crew may move you to the nearest island (e.g., Staniel Cay, 10–20 miles) for pickup.
Delays:
- Human: Crew hesitates or EMS misjudges severity—adds 15–30 minutes.
- Remote: Limited EMS boats/helicopters in the Exumas—response lags 30–60 minutes.
- Communication: Spotty VHF/cell signal delays contact—30+ minutes.
Why Pay?: Local boat operator demands $1,000–$2,000 for urgent transport—won’t wait for insurer approval.
Prep: Carry $2,000–$5,000—pays for initial boat move.

Step 3: Notify Insurance Hotline (30–90 Minutes)

Action:
- Call DAN (+1-919-684-9111) or DiveAssure (Duke line): After EMS, report: “Type 2 DCS, Exumas, neurological symptoms, need Nassau chamber.” Give boat coordinates, EMS status, and condition.
- Expect Approval: DAN: 15–60 min; DiveAssure: 20–60 min—coordinates airlift to Nassau.
Delays:
- Human: Buddy forgets EMS-first rule or stumbles on details—adds 15–30 min.
- Paperwork: DAN/DiveAssure need EMS report—fax delays from boat push 60+ min.
- Remote: Weak signal or time zone (EST) lags contact—30–60 min extra.
- Out-of-Network: Nassau air service unfamiliar with DAN—negotiation slows 30 min.
- Communication: Call drops or language gap with crew—60+ min.
- Red Tape: Hospital demands deposit verification—adds 30–60 min.
- Insurer-Specific: DAN’s peak-season call volume or DiveAssure’s after-hours staffing—15–60 min stretch to 90+.
Why Pay?: EMS or air service bills $10,000–$25,000 upfront—approval lags behind action.
Prep: Have $20,000–$30,000 (credit card)—covers evacuation if delays hit.

Step 4: Evacuation to Nassau (1–3 Hours Post-Approval)

Action:
- Transport: Helicopter (preferred, 45–60 min to Nassau) or boat-to-plane (2–3 hours total). DAN/DiveAssure arranges with Bahamas Air Sea Rescue or private service.
- Destination: Doctors Hospital, Nassau—hyperbaric chamber available (24/7, +1-242-302-4600).
Delays:
- Human: Pilot miscoordinates landing—30 min.
- Remote: Weather (e.g., storms) grounds flights—1–2 hours.
- Out-of-Network: Private chopper demands cash ($20,000)—won’t bill DAN directly.
- Red Tape: Customs or hospital entry rules—30–60 min.
Why Pay?: Helicopter insists on $20,000–$25,000 payment—direct payment stalls due to delays.
Prep: $25,000–$30,000 limit—ensures airlift happens.

Step 5: Hyperbaric Treatment (3–6 Hours Post-Incident)

Action:
- Recompression: Doctors Hospital chamber starts USN Table 6 (5–6 hours, ~$5,000–$10,000).
- Insurance: DAN/DiveAssure covers treatment—direct payment to hospital.
Delays:
- Paperwork: Hospital needs DAN policy confirmation—1–2 hours if faxed late.
- Red Tape: Deposit ($2,000–$5,000) required—delays treatment start.
Why Pay?: Deposit or initial fees hit you—$2,000–$5,000—until direct payment clears.
Prep: Have $5,000–$10,000—covers hospital entry.

Step 6: Post-Treatment and Reimbursement (Days–Weeks)

Action:
- Monitor: Stay in Nassau 24–48 hours—$200–$400 hotel.
- Claim: Submit receipts to DAN/DiveAssure—refunds in 30–60 days.
Why Pay?: Hotel, transport ($500–$1,000)—not covered by direct payment.
Prep: Keep $1,000–$2,000—handles recovery costs.

Total Time and Cost Estimate

Time: 3–6 hours from incident to chamber—best case (3 hours) with fast EMS and DAN approval; worst case (6+ hours) with delays.
Potential Out-of-Pocket:
- Minimum: $5,000–$10,000 (boat, deposit, incidentals).
- Worst Case: $25,000–$40,000 (helicopter, hospital fees, extras) if all delays hit.
Covered: DAN/DiveAssure eventually pay $30,000–$50,000 (evacuation + treatment).

Why You Need Cash Despite Direct Payment

Human Delays: Panicked buddy or slow crew—$2,000 boat before DAN approves.
Paperwork/Red Tape: Hospital deposit ($5,000)—DAN lags 2 hours.
Remote/Communication: Boat demands $15,000—signal drops delay DiveAssure.
Out-of-Network: Helicopter bills $25,000—won’t wait for DAN.
Insurer Delays: Peak calls push DAN to 90 minutes—$20,000 upfront.
Extras: $1,000 hotel—outside coverage.

Recommended Preparation

Financial Buffer: Credit card with $30,000–$40,000 limit—covers worst-case $25,000 evacuation + $5,000 deposit + $1,000 extras.
Insurance: DAN Guardian ($135/year)—call post-EMS, expect 15–90 min approval.
Gear: O₂ kit on boat, VHF radio, sat phone (if possible)—cuts communication delays.
Plan: Pre-brief buddy: “EMS first, then DAN at +1-919-684-9111”—reduces human error.

Final Notes

For Type 2 DCS in the Bahamas’ Exumas, expect 3–6 hours to Nassau’s chamber with DAN/DiveAssure. Delays—human panic, remote logistics, paperwork, out-of-network refusals, comms failures, red tape, or insurer bottlenecks—mean you’ll likely pay $5,000–$40,000 upfront, reimbursed later. A $40,000 credit limit ensures you’re airlifted fast—vital when numbness turns to paralysis. Stay safe: slow ascents (30 ft/min), safety stop (15 ft, 3–5 min), and 100% O₂ on surfacing.
