Nursing Guide

Comprehensive clinical reference for HBOT nursing in the Gulf region — physiology, chamber operations, safety, wound care, and GCC-specific practice contexts.

Physiology of Hyperbaric Oxygen
Henry's Law

The amount of gas dissolved in a liquid is proportional to the partial pressure of that gas above the liquid.

  • At 1 ATA breathing air: ~0.3 mL O₂/dL dissolved in plasma
  • At 3 ATA breathing 100% O₂: ~6 mL O₂/dL dissolved in plasma
  • Dissolved O₂ alone can meet resting tissue needs (~6 mL/dL required)
  • Enables oxygen delivery independent of haemoglobin — critical in CO poisoning and severe anaemia
Boyle's Law in HBOT

At constant temperature, pressure × volume = constant (PV = k).

  • Gas spaces in the body compress on descent and expand on ascent
  • Middle ear, sinuses, lungs, dental cavities, bowel gas all affected
  • Explains barotrauma risk if gas spaces cannot equalise
  • Guides contraindication assessment (trapped gas = risk)
  • At 2 ATA: gas volume halves; at 3 ATA: volume reduces to one-third
Hyperoxia Effects
  • Vasoconstriction: 20–25% reduction in blood flow — reduces oedema in crush injuries
  • Angiogenesis: stimulates new vessel growth in hypoxic wound beds
  • Antimicrobial: direct bactericidal effect on anaerobes; enhances neutrophil killing
  • Carbon monoxide displacement: accelerates COHb half-life from ~5 h (air) to ~20–30 min
  • Fibroblast stimulation: promotes collagen synthesis and wound repair
  • Osteogenesis: enhances bone healing in refractory osteomyelitis
  • Stem cell mobilisation: doubles circulating bone marrow progenitor cells
Pressure Units
  • ATA = Atmospheres Absolute (includes surface pressure)
  • 1 ATA = surface (sea level) pressure
  • 2 ATA = 10 metres sea water (msw) equivalent
  • 2.4 ATA = most common wound healing pressure
  • 3 ATA = 20 msw — used for CO poisoning, gas gangrene
  • FSW = feet sea water; 33 FSW = 1 additional ATA

Nurse Roles in a Hyperbaric Unit
Outside Attendant (Tender)
  • Pre-treatment patient assessment and vital signs
  • Chamber preparation and safety checks
  • Coaching ear-clearing and communication during dive
  • Monitoring patient through chamber viewport/camera
  • Operating chamber controls under physician direction
  • Managing emergencies: fire, medical deterioration
  • Documentation of treatment parameters
Inside Attendant (Multiplace Only)
  • Accompanies patients inside pressurised chamber
  • Must be CHT (Certified Hyperbaric Technologist) certified
  • Manages oxygen masks, hood, or tent systems
  • Assesses and responds to medical emergencies under pressure
  • Performs CPR and basic life support inside chamber
  • Must be fit to dive — own ear/sinus clearance ability
  • Cannot have absolute contraindications to pressure
Absolute Contraindication — Do Not Proceed Untreated pneumothorax is the only absolute contraindication to HBOT. Air trapped in the pleural space will expand on decompression, causing tension pneumothorax. Insert chest drain before any hyperbaric treatment.
Absolute Contraindications
  • Untreated pneumothorax — must insert chest drain first
(All other contraindications are relative and require risk-benefit assessment)
Relative Contraindications
  • COPD with CO₂ retention (hypercapnic drive — monitor closely)
  • Active upper respiratory tract infection (impairs ear/sinus equalisation)
  • Uncontrolled high fever (>38.5°C) — lowers seizure threshold
  • Severe claustrophobia — requires anxiolytic management plan
  • Uncontrolled congestive cardiac failure
  • Concurrent cisplatin or doxorubicin chemotherapy (pulmonary O₂ toxicity)
  • Concurrent bleomycin (potentiates pulmonary fibrosis)
  • Optic neuritis (avoid in acute MS relapse)
  • Implanted devices: pacemakers must be pressure-tested (most modern ones safe)
  • Pregnancy: relative — acceptable for life-threatening indications (CO poisoning)
Pre-Dive Assessment Checklist
Ear and Sinus Clearance
Valsalva Manoeuvre Training
  • Pinch nose, close mouth, gently blow — increases middle ear pressure
  • Should feel "popping" sensation — equalisation achieved
  • Teach before first session — practise at surface
  • Should be gentle — forceful Valsalva risks round window rupture
  • Frenzel manoeuvre: tongue against soft palate, "K" sound — more controlled
  • Toynbee: swallow with nose pinched — helps on ascent
  • Instruct to equalise every 30 cm of descent, before pain develops
When to Pause / Abort Descent
  • Patient signals ear pain — stop compression immediately
  • Allow time to equalise before continuing
  • Consider decongestants (oxymetazoline nasal spray 20 min prior)
  • Decongestants: risk of rebound congestion with repeated use
  • Myringotomy: surgical option for recurrent equalisation failure
  • Document each session's equalisation tolerance
Fire Safety — Prohibited Items
Oxygen-Enriched Atmosphere Risk At 2–3 ATA with 100% O₂, the fire triangle is critically altered. Ignition energy is dramatically reduced. All sources of ignition and flammable materials are absolutely prohibited.
Prohibited — Never Take Into Chamber
  • Lighters, matches, battery-powered devices (sparking risk)
  • Mobile phones, smart watches, electronic devices
  • Petroleum-based lotions, creams, ointments (Vaseline, lip balm)
  • Synthetic fabrics: polyester, nylon, lycra, spandex, wool
  • Flammable hair products, perfumes, deodorant sprays
  • Nail polish, nail polish remover
  • Newspapers, magazines (standard paper — dust/combustion)
  • Hearing aids with zinc-air batteries
  • Wigs (synthetic material)
  • Loose dentures (aspiration risk if seizure; also retention risk)
Approved Materials
  • 100% cotton clothing and gowns (provided by unit)
  • Water-based personal care products only
  • Approved hyperbaric-safe medical equipment
  • Stainless steel non-sparking instruments
  • Cotton-based books/materials (some units allow)
  • Unit-provided entertainment (hyperbaric-rated screens)
  • Water in approved containers
Anxiety and Claustrophobia Management
Management Strategies
  • Thorough pre-treatment orientation — show chamber, explain process
  • Allow patient to view chamber before first session
  • Systematic desensitisation: progressive exposure therapy
  • Low-dose benzodiazepines (lorazepam 0.5–1 mg) — physician order
  • Breathing exercises: 4-7-8 technique, box breathing
  • Multiplace chamber preferred for claustrophobic patients (more space)
  • Distraction: music, audiobooks, films via in-chamber entertainment
  • Communication: continuous two-way intercom, emergency abort button
  • Reassure patient they can stop treatment at any time
  • Document anxiety level 0–10 scale each session

Pressurisation and Depth
Compression (Descent)
  • Standard compression rate: 1 psi/min (~0.068 ATA/min) — adjustable
  • Slow compression if patient has ear difficulty
  • Coach ear clearing every 0.2 ATA / 30 cm equivalent
  • Ear squeeze (barotitis media) is the most common complication
  • Monitor patient continuously via viewport or camera
  • Signal system: hand signals agreed before dive
  • Temporary pause of compression allowed — communicate with patient
Decompression (Ascent)
  • Controlled rate: typically 1 psi/min
  • Reverse squeeze: expanding gas exits middle ear — usually self-resolving
  • Do not ascend faster than treatment table specifies
  • USN Table 6: specific ascent/stop profile must be followed precisely
  • Ascent rate violation increases DCS risk in patients already at risk
  • Patients should breathe normally — no breath-holding on ascent

Air Breaks — Oxygen Toxicity Prevention
Air Break Protocol

Air breaks interrupt oxygen breathing to reduce cumulative pulmonary oxygen toxicity. UPTD (Unit Pulmonary Toxic Dose) is tracked for each patient.

  • Typical: 20 min O₂ → 5 min air → 20 min O₂ → 5 min air → 20 min O₂
  • During air break: patient breathes chamber air (monoplace: not possible) or switches to air supply (multiplace)
  • In monoplace: some protocols use 90 min O₂ unbroken at 2.0 ATA — physician decision
  • UPTD limit: ~1440 units/treatment; cumulative tracking important
  • USN Table 6: extended air breaks built into decompression profile
  • Pulmonary symptoms (cough, chest tightness) → extend/add air breaks
  • CNS symptoms → abort dive immediately; do not start air break in situ
USN Table 5 and Table 6 Overview
USN Treatment Table 5
  • Depth: 60 FSW (2.8 ATA)
  • Total time: 135 minutes
  • Indications: mild DCS (pain-only), mild CO poisoning
  • O₂ breathing: 20 min on / 5 min air cycles at 60 FSW
  • Ascent with stops at 30 FSW and 0 FSW
  • Can be extended with physician authorisation
USN Treatment Table 6
  • Depth: 60 FSW (2.8 ATA)
  • Total time: 285 minutes (4.75 hours)
  • Indications: serious DCS, AGE, severe CO poisoning
  • O₂/air cycles at 60 FSW then 30 FSW
  • Extensions: up to 2 additional 25-min O₂ periods at 60 FSW
  • Most commonly used recompression table globally
Emergency Procedures in Chamber
Emergency Inside Chamber — Priority Order 1. Protect patient and attendant safety. 2. Notify outside operator immediately. 3. Follow emergency protocol. 4. Do not panic-ascend — uncontrolled ascent causes AGE.
Medical Emergency
  • Seizure: remove O₂ mask, protect airway, do not restrain, time seizure
  • Cardiac arrest: begin CPR; ascent only after physician order
  • Respiratory distress: switch to air; assess for pulmonary OT
  • Loss of consciousness: assess AVPU; remove O₂, maintain airway
  • Controlled emergency ascent: physician authorises rate
Fire Emergency
  • Announce FIRE immediately via intercom
  • Outside operator: initiate emergency decompression (controlled)
  • Inside attendant: use chamber fire suppression if available
  • Monoplace: emergency decompression valve — operator decision
  • Do not open chamber door under pressure
  • Activate facility fire alarm; evacuate area
  • CO₂ extinguisher positioned outside chamber door always
Oxygen Toxicity
CNS Oxygen Toxicity — VENTID Mnemonic
V
Visual changes — tunnel vision, visual field narrowing
E
Ears — tinnitus, ringing, hearing changes
N
Nausea — with or without vomiting
T
Twitching — facial/lip twitching, muscle fasciculations
I
Irritability / anxiety — sudden unexplained agitation
D
Dizziness — vertigo, disorientation
Any VENTID symptom → immediately remove O₂ mask and breathe air. Notify physician. Do NOT continue treatment. If seizure follows: protect airway, time event, controlled ascent.
Pulmonary Oxygen Toxicity
  • Develops over cumulative exposure — not acute seizure risk
  • Symptoms: substernal chest burning, dry cough, dyspnoea
  • Mechanism: free radical damage to pulmonary endothelium
  • Tracked via UPTD (Unit Pulmonary Toxic Dose)
  • 1 UPTD = breathing 100% O₂ at 1 ATA for 1 minute
  • Safe limit: ~1440 UPTD per treatment day
  • Reversible if caught early; air breaks are the prevention
  • At-risk: patients with pre-existing pulmonary disease
Risk Factors for O₂ Toxicity
  • Higher pressures (3 ATA > 2.4 ATA)
  • Fever (lowers seizure threshold)
  • CO₂ retention
  • History of seizures (relative contraindication)
  • Stimulant drugs, amphetamines
  • Anxiety and hyperventilation
Barotrauma
TypeMechanismSymptomsManagement
Middle ear squeezeFailure to equalise on descent — Boyle's LawEar pain, pressure, bloody otorrhoea, TM ruptureStop/slow compression; decongestants; ENT review
Sinus squeezeBlocked sinus ostia — trapped gasFacial/frontal pain, epistaxis, headacheDecongestants; nasal spray pre-treatment; ENT if persistent
Pulmonary over-inflationBreath-holding on ascent — gas expandsChest pain, dyspnoea, subcutaneous emphysema, AGEEmergency: recompress if AGE; support; do NOT re-ascend rapidly
Dental barotraumaTrapped air under fillings/crownsTooth pain during compression or decompressionPause; dental review between sessions
GI barotraumaIntestinal gas expansion on ascentAbdominal pain, distension, flatulenceUsually benign; slow ascent; avoid carbonated drinks pre-dive
Mask squeezePressure differential across face maskFacial bruising, periorbital ecchymosisProper mask fit; exhale into mask on descent
Pneumothorax Emergency Protocol
Tension Pneumothorax Risk During HBOT A previously undetected pneumothorax may be asymptomatic at surface but become life-threatening during decompression as trapped pleural gas expands. Pre-treatment CXR is essential.
Response Protocol
  • Suspect if sudden chest pain + dyspnoea during treatment
  • Notify physician immediately via intercom
  • Do NOT rapid ascent — gas will expand further → tension pneumothorax
  • Controlled slow ascent per physician direction while preparing for intervention
  • On chamber exit: immediate needle decompression if tension; chest drain insertion
  • Document: exact time of symptom onset, pressure at time, intervention taken
Decompression Sickness vs. Worsening Indication
DCS in Hyperbaric Patients (Non-Divers)

Very rare in HBOT patients. Risk exists only if ascent is too rapid or patient has patent foramen ovale (PFO).

  • Type I (musculoskeletal): joint pain, skin bends (cutis marmorata)
  • Type II (neurological): sensory changes, weakness, bladder dysfunction, vertigo
  • Treatment: recompress on USN Table 5 or 6
  • Prevention: strictly adhere to ascent rate protocols
Post-Treatment Vision Changes
  • Myopia: most common side effect of multiple HBOT sessions
  • Mechanism: lens water content changes / refractive index shift
  • Onset: typically after 20+ sessions
  • Magnitude: 1–3 dioptres of myopic shift typical
  • Reversible: vision returns to baseline 6–8 weeks after completing treatment series
  • Advise patients not to get new glasses during treatment course
  • Document baseline visual acuity before starting elective series
Fire Risk Management
Fire Triangle in Hyperbaric Environment

OXIDISER
Elevated partial pressure dramatically lowers ignition energy and accelerates combustion
🔥
IGNITION SOURCE
Electrical sparks, static electricity, battery devices, friction — all prohibited
💧
FUEL
Synthetic fabrics, petroleum products, flammable materials — strict prohibition
  • CO₂ extinguishers placed immediately outside chamber doors — never CO₂ inside monoplace
  • Fire suppression systems: Halon alternatives in modern chambers
  • Staff fire training mandatory — annual drills required
  • Static electricity: cotton gowns reduce static buildup
  • Anti-static flooring in hyperbaric suite
Wound Assessment Protocol
At Each HBOT Session
  • Inspect wound before treatment: size (length × width × depth), colour, tissue type
  • Document granulation tissue progress: pale pink → red granulation is positive
  • Measure wound at baseline and every 5–10 sessions
  • Standardised wound photography: consistent lighting, distance, ruler in frame
  • Assess wound edges: undermining, tunnelling, maceration
  • Note exudate: amount, colour, consistency, odour
  • Periwound skin: erythema, oedema, induration (signs of infection/cellulitis)
  • Assess limb perfusion: ABPI, Doppler waveforms baseline and during series
  • Temperature differential: warm wound = active healing / infection
  • Document pain score at wound site
  • Biofilm indicators: failure to progress, slough reformation, odour
  • Photography at sessions 1, 10, 20, 30 (formal documentation)

Diabetic Foot Ulcer Protocol
Patient Selection (Wagner Classification)
  • Wagner I–II: superficial/tendon involvement — HBOT not indicated routinely
  • Wagner III: deep ulcer with osteomyelitis/abscess — HBOT adjunct
  • Wagner IV: forefoot gangrene — HBOT with vascular intervention
  • Wagner V: whole foot gangrene — HBOT to optimise salvage attempt
  • TcPO₂ <40 mmHg at wound edge predicts poor healing; <20 mmHg = critical
  • TcPO₂ at 2.4 ATA O₂ >200 mmHg: good predictor of HBOT response
DFU HBOT Nursing Considerations
  • Check BGL before each session: hypoglycaemia risk under pressure
  • Target pre-HBOT BGL: 5–15 mmol/L (90–270 mg/dL)
  • Hypoglycaemia awareness: headache, diaphoresis, confusion — can mimic O₂ toxicity
  • Insulin pump management: discuss with endocrine team
  • Offloading: ensure total contact casting or boot compliance
  • Vascular review: ABI, revascularisation if indicated, concurrent to HBOT
  • Multidisciplinary team: HBOT nurse, wound RN, vascular surgeon, podiatry, endocrine
Radiation Wound Management
Radiation-Induced Hypoxic Tissue Injury

Radiation causes an obliterative endarteritis — progressive hypoxic, hypovascular, hypocellular tissue. HBOT reverses relative hypoxia and drives angiogenesis.

Osteoradionecrosis (ORN)
  • Most common: mandibular ORN after head/neck radiotherapy
  • HBOT protocol: 30 sessions pre-surgery + 10 post-surgery (Marx protocol)
  • Pressure: 2.4 ATA × 90 min
  • Outcome: improved bone healing, reduced infection, avoid further surgery
Radiation Cystitis
  • Haematuria, urgency, dysuria after pelvic radiotherapy
  • HBOT: 20–40 sessions at 2.0–2.4 ATA
  • Response rate: 70–85% complete haematuria resolution
Radiation Proctitis
  • Rectal bleeding, urgency, tenesmus
  • HBOT: 30–40 sessions; good evidence base
  • Alternative to argon plasma coagulation in refractory cases

Diving Medicine in the Gulf
UAE Pearl Diving Heritage

Pearl diving (ghaus) was the economic foundation of Gulf states before oil. Divers worked without equipment — breath-hold dives to 20–30 m, dozens of dives per day for months.

  • Historical DCS in pearl divers was documented — called "paralysis of the sea"
  • Modern recreational diving culture strong in UAE, Qatar, Bahrain, Kuwait
  • Red Sea (Saudi), Arabian Sea (Oman), Persian Gulf (UAE, Kuwait, Bahrain) — active dive sites
  • DAN (Divers Alert Network) active in UAE and broader GCC
  • Dive operators: required to have chamber access within reasonable range
Decompression Illness Presentations
  • Recreational diving DCS: exceeding no-decompression limits, rapid ascent
  • Technical diving DCS: deep dives >40 m, mixed gas use errors
  • Freediving: shallow water blackout ≠ DCS; hypoxic cause
  • AGE: barotrauma on ascent — most common cause of diving death
  • Time to recompression critical: <6 hours optimal; delays worsen outcome
  • Transfer to chamber: do not wait; 100% O₂ during transport
  • Nearest chamber information should be pre-established for all dive sites
GCC-Specific HBOT Indications
CO Poisoning — Regional Context
  • Generator use: common in GCC due to power outages, construction sites, remote areas
  • Building fires: concrete construction — CO accumulates in enclosed spaces
  • Shisha (hookah) cafes: poorly ventilated, CO accumulation documented
  • Vehicle exhaust in underground parking: chronic low-level CO exposure
  • Ramadan context: outdoor generators for iftar gatherings
  • Water heaters: poorly vented gas heaters in older buildings
  • Construction worker exposures: petrol-powered equipment in confined spaces
Heat-Related Illness
  • Gulf summer: ambient temperatures 45–50°C; heat index >65°C in humidity
  • Exertional heat stroke in outdoor workers: neurological sequelae
  • HBOT for heat stroke neurological injury: emerging evidence
  • Hyperthermia lowers seizure threshold in HBOT — ensure normothermia
  • Pilgrimage (Hajj): mass casualty heat events; HBOT in Makkah and Madinah facilities
  • Military heat injury: Gulf militaries active in high-heat environments
Military Diving Medicine
GCC Military Hyperbaric Facilities
  • UAE Navy and Special Operations: dedicated hyperbaric facilities — Zayed Military Hospital
  • Saudi Arabia: Royal Saudi Naval Forces — eastern province hyperbaric
  • Kuwait: Kuwait Naval Force — HBOT for combat diving casualties
  • Bahrain: BDF Hospital — naval medicine, US 5th Fleet nearby increases cases
  • Military HBOT: also used for traumatic wound care, refractory infections in combat injuries
  • Special operations: combat diver training — higher DCS risk with aggressive protocols
  • Closed-circuit rebreathers: O₂ toxicity risk — military divers at higher CNS-OT risk
