The 17 year old male, 1 of a party of 4, had twisted his ankle on rough ground near Llyn Cau, but then also began to experience an asthma attack. With no inhaler with him, he was reported to be deteriorating quickly.
With the potential seriousness of an untreated asthma attack in mind, a request for aircraft assistance was placed immediately.
Coastguard helicopter Rescue936 was dispatched, flying directly to the casualty site and deploying the winchman paramedic to attend to the man. In the meantime, the aircraft descended to Minffordd and uplifted a small group of Team volunteers to carry the man by stretcher a short distance to the aircraft.
The casualty party and Team members were down-lifted to the foot of the mountain, before the casualty was flown to Ysbyty Gwynedd, Bangor, for further assessment and treatment.
