For the record

“Revealed: scale of ‘unnecessary’ NHS deaths” (News, last week, page 1), contained several editing errors. The article concerned a report by the National Confidential Enquiry into Patient Outcome and Death into the use of non-invasive ventilation (NIV) in patients with severe breathing difficulties. This term was changed confusingly to “non-invasive intervention”, which was described incorrectly as “emergency oxygen treatment” and “oxygen through a face mask”. Non-invasive ventilation forces air and oxygen into the lungs when a patient is too weak to breathe unaided. This is administered through a tight-fitting mask (non-invasive) rather than via a tube inserted into the airway (invasive). Oxygen treatment, given to the majority of patients attending hospital in an emergency, should not be confused with NIV.

The new French prime minister is Édouard Philippe, not Manuel Valls, as we had it in “Dublin streets ahead of EU rivals as City firms plan for Brexit relocation” (Business, last week, page 42).

“Federer has trump card” (Sport, last week, page 4) said Marin Cilic “won Queen’s stylishly before Wimbledon”. True, but in 2012 – not this year.
