The quicker the better. Best to start him on the right treatment if required. The biggest sign when to phone the ambulance is if he struggling to breath.
Wish you the best of luck.
Not sure if this is the best advice but maybe give NHS Direct a call and explain his situation and his current symptoms.
As @Blueclouds said, the sooner the better in his circumstances. Hope it all goes ok mate
Give the NHS line a call and give them as much info as possible and get some advice WB. Rather be over cautious, to be on the safe side.
Thank you. On hold atm. Keep asking him about his breathing but he’s stubborn and I worry he’ll only say “yes I need an ambulance” when it’s a bit too late.
