The Oireachtas Transport Committee is due to begin an investigation today into the provision of first-aid equipment on flights and the training of cabin crews to deal with medical emergencies.
Officials from the Department of Transport and the Irish Aviation Authority are due before the committee to answer questions on the matter.
The investigation follows the death of a 24-year-old woman on a Ryanair flight from Treviso to Dublin last month.
Concern was raised at the time about the lack of medical equipment on board, but Ryanair insisted all its aircraft were stocked with first-aid kits as required by EU law and all staff were trained in CPR.
