A technical dive plan is usually a beautiful document. Bottom mix, travel and deco gases, run times, turn pressures, lost-gas contingencies, a bailout schedule for every possible failure. Most of it is about staying out of trouble underwater.
Very little of it is about what happens forty minutes after surfacing, on a liveaboard eight hours out of Hurghada, when a team-mate says their shoulder aches and their fingers feel strange. That is the part of the plan that decides whether a bad day becomes a permanent injury, and for divers based in Hurghada it is almost entirely about three things: where the chambers are, how long it takes to reach one, and whether there is enough oxygen on board to bridge the gap.
This article is a practical framework for building that plan before technical diving from Hurghada. It is not medical advice. Any suspected diving injury needs a diving-medicine physician, and the emergency hotlines run by Divers Alert Network (DAN) exist precisely for that call.
Why technical divers need a separate emergency plan
Technical divers carry more inert gas, for longer, at greater depth than recreational divers, and they often do it at sites chosen because they are remote. The Brothers Islands, the classic offshore liveaboard trip from Hurghada, sit far out in the open sea and are reached only by liveaboard 811.
Egypt's own regulator treats this seriously. The Chamber of Diving and Water Sports (CDWS) policy on depth limits sets maximum depths by qualification (45 m for decompression procedures dives, 55 m for extended range, 60 m for normoxic trimix and 100 m for hypoxic trimix, with a maximum bottom-mix PPO2 of 1.4 and deco-mix PPO2 of 1.6). For anything deeper, it requires the technical manager of the operation to review and approve, before the dive date, a list of emergency equipment at the site, the emergency plan, and proof of dive insurance covering the team to the planned maximum depth 10. In other words, an emergency plan is not an optional extra in Egypt; for the deepest dives it is part of the paperwork. Check with your operator that the version of the policy they work to is current.
Where the recompression chambers are
For divers based in Hurghada, the nearest hyperbaric facilities are in the city itself and in El Gouna, a short drive north. The table lists only facilities that a published source describes as serving divers, with the date of that source. Chamber availability, staffing and phone numbers change. Confirm the current status and contact details with your operator and with DAN before every trip; do not rely on any article, including this one.
| Facility | Location | What the source says | Source (date) | Before diving |
|---|---|---|---|---|
| HyperMed | Hurghada, next to the airport | Opened 2007 | Operator interview (2023) 2 | Confirm status |
| Diving and Hyperbaric Medical Centre, El Gouna Hospital | El Gouna, north of Hurghada | "Can treat decompression emergencies"; nine-patient chamber | El Gouna town site (undated) 4 | Confirm status |
Further chambers operate elsewhere on the Egyptian coast, including Sharm el-Sheikh, Dahab and Marsa Alam 123, which matters on liveaboard routes that finish far from Hurghada.
Two practical points follow. First, Hurghada has more than one option within reach, which matters if one chamber is busy or a patient needs a particular treatment. Second, every facility is on land, so the boat leg back to the marina and then the road are always part of the treatment timeline.
How far are Hurghada's dive sites from help?
Distances in the Red Sea are deceptive. A site that is an easy day trip in calm weather can be a long, slow passage when the northerly wind is up, and published figures vary widely with the boat. Treat the numbers below as rough, calm-weather ranges from published guides, and replace them with your operator's own typical transit times.
| Site | From | Approximate distance | Published transit | Source |
|---|---|---|---|---|
| Giftun Islands | Hurghada | Close offshore | About 20-40 minutes | 9 |
| Abu Nuhas | Hurghada | About 25 miles | A full-day trip: the boat leaves Hurghada around 06:00 and is back around 17:30 | 12; schedule from a Hurghada operator (2026) |
| SS Thistlegorm | Hurghada | About 65 km (about 35 nmi) | About 4.5 hours | 13 |
| Brothers Islands | Hurghada, by liveaboard | About 150 km (about 81 nmi) | About 8 hours, an overnight crossing | 11 |
DAN Europe's own description of the Brothers puts it bluntly: the islands lie in the middle of the Red Sea, "with the nearest hyperbaric chamber several hours navigation away", and at the time of writing it noted that a search-and-rescue service was not active there 8. That article dates from 2017, so ask your operator what air or sea evacuation is available today. Either way, the planning assumption for an offshore technical trip from Hurghada should be hours, not minutes, between the first symptom and a chamber door.
Oxygen: the bridge between symptom and chamber
The single most useful first-aid intervention for suspected decompression illness (DCI) is breathing oxygen at the highest concentration possible, as early as possible. The 2018 expert review of pre-hospital DCI management in Diving and Hyperbaric Medicine recommends normobaric oxygen "as soon as possible after onset of symptoms", at an inspired fraction close to 100%, with enough supply for the evacuation 5. DAN's guidance is consistent: give emergency oxygen right away 6, and keep it going unless a diving-medicine specialist advises otherwise 7.
The quantity is where plans quietly fail. DAN Asia-Pacific's guidance to operators is that they must plan "to ensure that enough oxygen will be available for the expected transport time between the dive site and a suitable medical facility", which in remote locations can mean many hours or even days. The equipment should deliver near-100% oxygen through a demand valve, or through a non-rebreather mask at 10 to 15 litres per minute 7.
An illustrative calculation (the numbers are for showing the method, not a prescription):
- Expected time from the Brothers back to a Hurghada chamber: assume 8 hours of sailing plus 1 hour of road transfer and handover, so about 9 hours, or 540 minutes.
- Flow through a non-rebreather mask: 15 litres per minute.
- Oxygen needed for one casualty: 540 × 15 = 8,100 litres.
- A common small first-aid cylinder (an M9 in DAN's Rescue Pak) holds 255 litres when full, and DAN rates it at about 15 minutes at 15 litres per minute 14.
On those assumptions, one diver would need the equivalent of more than thirty small first-aid cylinders. That is why large-capacity oxygen cylinders on board, a known regulator connection, and a clear answer to "how many hours can we keep one diver, or two, on oxygen?" belong in the pre-trip checklist. Ask the operator directly, and do the arithmetic yourself for the longest leg of the trip.
Recognising decompression illness without diagnosing it
Technical divers are good at problem-solving underwater and, as a group, often bad at admitting something is wrong on the surface. DAN notes that "denial is arguably the worst 'symptom' of DCS" 6.
According to DAN, symptoms can appear immediately after surfacing or up to 24 hours later, most often between 15 minutes and 12 hours after a dive 6. They include unusual fatigue, joint or muscle pain, dizziness, numbness or tingling, weakness, rash, shortness of breath and confusion 6. A study of more than 5,000 cases treated at a single hyperbaric unit found that most first symptoms appeared within the first hour or so after surfacing, and almost all within 24 hours 15.
The working rule for the boat is simple: if a symptom is new after a dive, treat it as possible DCI. Put the diver on oxygen, keep them still and lying flat if practical, give non-carbonated, non-caffeinated, non-alcoholic fluids if they are fully conscious, and call a diving-medicine physician or the DAN hotline 56. Do not try to decide on the boat whether it is "only" a strained shoulder.
In-water recompression: know the debate, do not improvise
In-water recompression (IWR) means taking a diver with DCI back underwater, usually breathing oxygen at a shallow depth, as a stop-gap where a chamber is far away. It is controversial. A 2018 review in Diving and Hyperbaric Medicine found no data establishing its benefit over conventional surface oxygen and transport, but accepted that, "conducted by properly trained and equipped divers", it may be justified for life- or limb-threatening symptoms where timely recompression is unavailable. It specifically says the risk is not justified for mild symptoms, or for divers too impaired to be safe in the water 16.
The companion expert review frames it the same way: an option only in remote locations without chamber access, for significant symptoms, with every team member trained and equipped, using oxygen at no more than 9 m 5. That rules out the improvised version, a confused diver sent back down on a stage cylinder with an untrained buddy. If a team intends IWR to be part of its remote-site plan, that is a decision to make, train and equip for months before the trip, with medical input, not on the deck.
Insurance: read the depth line before you pack
Many divers buy dive insurance and never read the conditions that matter for technical diving: depth limits, permitted gases, decompression and evacuation cover. Policies differ, and they change.
As one example, DAN Europe has published that technical diving is covered under its insurance policies with the exception of its entry-level Sport Bronze plan, which is limited to 40 m on air or nitrox, and that divers planning to exceed 130 m should inform DAN before the dive 17. That article is from 2012, so treat it as an illustration of what to look for, not as current policy wording. The questions to ask any insurer are: what is the maximum covered depth, are trimix and decompression dives covered, does cover include evacuation from a liveaboard and recompression treatment abroad, and are there partial-pressure conditions. Get the answers in writing. In Egypt the CDWS policy expects proof of cover to the planned maximum depth for the deepest dives 10.
Flying home: the last leg of the plan
DAN's consensus guidelines, from its 2002 Flying After Diving Workshop, recommend a minimum 12-hour surface interval after a single no-decompression dive, 18 hours after multi-day repetitive diving, and "substantially longer than 18 hours after diving involving compulsory decompression, or using heliox and trimix" 18. The guidelines were derived from dry chamber trials with resting volunteers, which is one more reason to be conservative after a week of deep, cold, working dives.
For a diver who has had DCI symptoms, the decision to fly is a medical one. The 2018 expert review notes that some divers with mild symptoms may be evacuated by commercial airliner after at least 24 hours, and that aircraft carrying DCI patients should ideally be pressurised to sea level or stay low 5. Plan the last diving day so the flight does not force a choice between the schedule and a margin.
Your Red Sea tech emergency plan, in one page
- Chambers: name the two nearest hyperbaric facilities to every site on the itinerary, and confirm with the operator and DAN that each is currently operating.
- Contacts: save the DAN emergency hotline for your region and the operator's emergency procedure. Know who on board makes the call.
- Distances: write down realistic transit times from each site to the nearest port and then to a chamber, and add a margin for bad weather.
- Oxygen: calculate litres needed for the longest leg (minutes × flow rate) for at least one casualty, then confirm the boat actually carries that much, plus delivery equipment for a breathing and a non-breathing diver.
- Skills: make sure several people on the team are trained in oxygen first aid and know where the kit is stored.
- Symptoms: agree as a team that any new post-dive symptom is reported immediately and treated as possible DCI.
- IWR: decide in advance whether in-water recompression is in or out. If it is out, say so. If it is in, train and equip for it with medical input.
- Insurance: check depth, gas, decompression, evacuation and recompression cover, in writing.
- Paperwork: for deep dives, expect the operator to ask for qualifications, dive plan, gases, the emergency plan and proof of insurance, as the CDWS policy requires.
- Flights: schedule the last dive so the surface interval before flying is well beyond 18 hours after decompression or trimix dives.
Key takeaways
- Hurghada's nearest hyperbaric facilities are in the city and in El Gouna; offshore technical sites put hours of transport between a diver and treatment.
- Early, high-concentration oxygen is the key first-aid step, and it must last for the whole evacuation; do the litres-per-minute arithmetic before the trip.
- Treat any new post-dive symptom as possible DCI and get diving-medicine advice; do not self-diagnose.
- In-water recompression is a specialist option for trained, equipped teams in remote locations, not an improvised fix.
- Check that insurance covers your planned depth, gases, decompression and evacuation, and leave a long margin before flying.
