Emirates, the Dubai-based international airline, has become the world's first air carrier to respond to current, world-wide fears about deep vein thrombosis (DVT) by providing every passenger on its long-haul flights with an AiroGym

Passenger wins compensation from JMC (11th February 2002)
Tourist who feared DVT wins damages! The 56-year-old Cheshire man won £500 compensation from tour operator JMC over fears he had come down with deep vein thrombosis. JMC considering running trials with the Airogym stated Geraldine Constable, Director of Cabin Services earlier this year.

Sunday Telegraph (January 2002)
The Airogym DVT cushion has been voted best tested travel and DVT product in the Sunday Telegraph, a reader's favourite too, receiving a five star rating! 'An excellent way to exercise while remaining seated and combat DVT.'

ECONOMY CLASS SYNDROME BLAMED IN DEATH OF FIRST CLASS PASSENGER - A British woman has died from a blood clot after flying from Miami to England. Her death has renewed calls for more research and action on 'economy class syndrome' or 'travellers' thrombosis. Ann Price died 24 hours after her flight. Her husband, John, says his wife had been a healthy person before her Feb. 26 flight. He called for more research in the problem of deep vein thrombosis (DVT) and airline passengers.

Telegraph - Long-haul DVT link admitted by airlines (14 March 2001)
AIRLINES have accepted a potential link between long-haul flights and potentially fatal blood clots. Air travel could be linked to deep vein thrombosis, said a meeting of scientists, aviation experts and representatives from 16 airlines organised by the World Health Organisation yesterday. The admission, and decision to launch an international study into why air travel could increase the risks of thrombosis, comes after years of denial by airlines. Research will take around two years and will look at whether seating, cramped conditions and air quality play a role in the condition. It will also investigate if preventative measures, such as surgical stockings or blood-thinning aspirin, reduce the risk.

Telegraph - DVT: victims' relatives demand EU action (15 June 2002)
British families of victims of deep-vein thrombosis (DVT), the condition frequently linked to flying, this week called on the European Union to make it compulsory for airlines to provide passengers with more detailed health briefings.

Telegraph - Definative DVT Study underway (25 May 2002)
The World Health Organisation has launched what is expected to be a definitive investigation into the causes of deep-vein thrombosis (DVT) in air travellers. It aims to determine the causes and frequency of DVT, a condition in which blood clots form in the lower legs. In severe cases clots can travel to the brain or lungs, causing death. The investigation will also try to establish the key risk factors and effective prevention methods. An estimated 2,000 people suffer from DVT in Britain each year.

BBC News - Neck cushion threat to air passengers (16th July 2002)
Inflatable neck cushions used by many airline passengers could explode - or end up strangling their wearer, say experts. They say the devices are potentially lethal and should be banned at once. Paul Richards, a former pilot himself - and the inventor of a device which allows a seated passenger to perform exercises which may ward off thrombosis - has also come up with a safety feature which releases the air inside the cushion in the event of decompression. He told BBC News Online: 'With any decompression in the cabin, the neck cushion grows and puts pressure on the neck. It can explode with a very high noise level - and possibly cause damage to the neck and injury to the spine. I am calling on airlines to ban all unsafe inflatables from aircraft.'

Daily Telegraph (24 August 2002)
This month a study was published which found that long trips in cars might also cause blood clots; the suitably-named Dr Emile Ferrari, a French cardiologist, warned that any four-hour journey could cause the condition.

Court told of DVT flight dangers - BBC News (5th November 2002)
Deep vein thrombosis can leave airline passengers crippled or dead, the High Court has heard. Fifty-six people are fighting a landmark legal case against 28 airlines for failing to warn them or their relatives about the risk of DVT, also known as economy class syndrome. Counsel Stuart Cakebread told the court in London there was a 'profound' impact of flying for long hours in cramped conditions. The three-day hearing began on Tuesday and will consider whether DVT can be classed as an accident under the terms of the 70-year-old Warsaw Convention.
