From his's wife's diary, it was necessary because the insertion site for the original was not working as expected: "Wednesday, 27th of August 2015 – Day 9 The nurse explained to me that they put another line in your neck, just to get extra line of blood to the lung machine as you need more oxygen to keep other organs working well. Your lung still is quite sick, the tube into your lung wasn’t working much comparing to the one from the lung machine." A little more context: "Monday, 25th August 2015 – Day 7 Your oxygen level requirement is 100% now, in case during night time at 3am, you need more oxygen, and there is no way they can feed you more here in Knox. So they need to cut a hole in your leg to put a man-made lung to pump extra oxygen in your body (as your lung is too inflamed), which can only be done in Alfred hospital."
