Travelling With Oxygen: Trains, Flights and Road Trips

Step 1: ask the doctor whether and how to travel

Before booking, see the doctor and ask:

• Is my parent fit to travel, and by which mode? Long journeys, flights and high altitudes can be risky for people with low oxygen, heart failure or recent flare-ups.
• What oxygen is needed at rest, on exertion, during sleep and at the destination? Does the flow change during travel, especially in flight, where cabin air has less oxygen (equivalent to about 2,000 to 2,500 metres), or at altitude?
• Should a fitness-to-fly or altitude assessment be done? Specialists sometimes do tests simulating cabin conditions for people with significant lung disease.
• Which devices are suitable: a portable concentrator, cylinders or both?
• Which medicines, inhalers and action plan to carry?
• Which doctor or hospital can be contacted at the destination?
• A written letter stating the diagnosis, oxygen prescription, flow rates and fitness to travel, as carriers often ask for it.

Do not guess the settings for travel. See oxygen flow rates and prescriptions: what families should know.

Step 2: choose the right equipment

Portable oxygen concentrator (POC). Battery-powered, rechargeable, and often the most practical option for trains, flights and hotels. Settings on pulse devices do not equal litres per minute, so the doctor or supplier should test your parent on the actual machine. Check that the machine can meet the prescription at travel settings, how long the battery lasts at that setting and what spare batteries you need. See portable oxygen concentrators: travel and daily use.

Small cylinders. Useful for road trips and as backup. Cylinders have strict rules for transport and are generally not allowed on commercial aircraft as passenger-supplied items. Check with each carrier.

Home concentrator at the destination. For a long stay, a rented concentrator at the destination may be easier than carrying your own; see renting breathing equipment: costs, checks and return.

Accessories: spare cannulas and tubing, extension cords and adaptors, a humidifier bottle if used, a fully charged oximeter with spare batteries, a torch, and a car adaptor for road trips.

Step 3: calculate how much oxygen and battery you need

For battery-powered units: work out the total travel time, including check-in, security, delays, transfers and a margin of at least a few hours, then check the battery life at your parent's setting and add spare batteries. A common rule is to carry enough battery life for one and a half times the expected journey, as some airlines require. For cylinders: divide the volume of gas by the prescribed flow in litres per minute, as explained in oxygen cylinder or concentrator: which suits home use?, and add a margin. Ask the supplier to help. Plan for recharging whenever sockets are available, but do not rely on them.

Flying

• Contact the airline well before booking, ideally 48 hours to several weeks before, depending on the airline, and ask for their medical clearance form and rules about oxygen. Rules differ: some allow only approved models of portable concentrators, some supply oxygen on board for a fee, and some do not permit oxygen at all on certain routes. Get the policy in writing.
• Passenger-owned cylinders are generally not permitted on board. Many airlines can supply oxygen on request, at a charge and with notice; the flow options may be limited.
• POCs are usually allowed if the model is approved by the airline and the aviation authority. Carry the manufacturer's statement of approval, if there is one, and the doctor's letter.
• Battery rules: lithium batteries must travel in the cabin, with terminals protected, and are limited by watt-hour rating and number. Check the airline's limits.
• Carry the machine in the cabin, not in checked luggage. Ask whether you may use it at the gate, on the ground and during boarding, and whether it can be charged on board (usually not).
• Seating: ask for a window or a seat that allows the machine to be placed under the seat in front, not in the exit row, and for assistance at the airport. See train, flight and airport assistance and travel with an elderly parent checklist.
• At security, inform staff, show the doctor's letter and expect extra checks.
• Allow extra time for check-in, security and transfer, and avoid tight connections.
• Plan for delays with spare batteries and a way to get help.

Trains and buses

• Ask the operator about rules for carrying medical equipment and oxygen, including cylinders, in advance. In India, rules differ by railway zone, class and train; confirm with the railway helpline or the station medical officer, and with the bus operator.
• Do not assume that charging sockets will be available or working; carry enough battery life for the whole journey plus delays.
• Choose a lower berth, a seat near the toilet and accessible position, and travel in the cooler part of the day. See travel with an elderly parent checklist.
• Station assistance: ask for wheelchair help, porter service and a path that avoids long walks and stairs.
• Fire safety: no smoking or flames, and tell co-passengers politely about the oxygen if asked; do not allow cooking stoves, incense or lighters nearby. Keep tubing from tripping fellow passengers.
• Secure the equipment so it does not slide or fall in motion.

Road trips

• Secure the equipment upright and padded; never in the boot of a closed hot car; a cylinder must be restrained and kept cool, in a ventilated space, and not left in a parked car in the sun.
• Use the car adaptor only as the maker instructs, and check the car's socket rating.
• No smoking in the vehicle. Keep the windows slightly open for ventilation.
• Plan breaks every few hours for rest, stretching and checking oxygen supply.
• Know the route to hospitals along the way, and keep the doctor's and supplier's numbers on hand.
• Avoid travel in extreme heat or at night on poor roads if possible.

Altitude and hill stations

At altitude, the air has less oxygen. People who need oxygen at sea level may need more, and some should avoid high places. Hill stations, mountain temples and pilgrimages such as high-altitude yatras can be dangerous for older adults with heart or lung disease. Ask the doctor before planning; do not adjust oxygen flow yourself. If symptoms such as unusual breathlessness, severe headache, confusion or chest tightness occur, descend and seek help; call 112.

Hotels, relatives and the destination

• Tell the host in advance about oxygen needs, fire safety and the need for a safe power socket; ask the hotel to avoid assigning a room over a kitchen or near smoking areas.
• Check the room: an earthed socket near the bed, no gas heater, geyser or open flame, and space for the equipment. See safe use of oxygen and electrical equipment.
• Arrange a rented concentrator and cylinder backup at the destination before arrival, with a delivery time and a contact number; see oxygen concentrators: a buying and renting guide.
• Locate the nearest hospital and pharmacy, and the supplier's service number.
• Power cuts may be common; carry backup. See oxygen at home and power cuts: a backup plan.
• Pilgrimage and temples: lamps, incense and camphor are fire risks near oxygen; keep a safe distance and choose quieter times.

Fire safety on the move

The same rules apply anywhere: no smoking, no open flames, no oil or grease on face or connections, and keep heat sources away. Do not use heaters or stoves near the person. Keep oxygen away from fireworks and crowded events with flames. Brief fellow travellers and hosts.

The travel kit

• Doctor's letter, oxygen prescription and fitness to travel; the action plan and the health summary; see emergency contact card and medical summary.
• Medicines for the journey plus extra for delays, in hand luggage, in original packs, with the prescription.
• Inhalers, a spacer and, if prescribed, a nebuliser with a battery.
• Oximeter with spare batteries; see pulse oximeters: how they work and how to use one.
• Spare cannula and tubing; spare batteries and chargers.
• Phone with power bank; list of contacts, including the supplier's helpline and 112.
• Insurance papers and ID.
• Snacks, water and comfortable clothing.

What to do if something goes wrong

• Battery low or machine alarm: switch to the backup supply, find a socket, rest and seek help. Do not increase flow without medical advice.
• Breathlessness worsening: sit upright, rest, use the reliever, check oxygen, and call the doctor; call 112 if severe, with blue lips, confusion or chest pain.
• Delays: tell the staff about the medical need; ask for assistance.
• Machine failure: use the backup, and contact the supplier and the doctor.

When to ask a professional

Ask the doctor for clearance, a written plan and a letter. Ask the supplier for travel settings, spare batteries and a destination rental. Ask the airline or railway for written rules. Ask a pharmacist about medicine supply. Call the doctor if your parent becomes more breathless, drowsy or confused, and call 112 for emergencies during travel.
