i wud remove my finger and check his pulse maybe try to start some cpr
contact the paramedics ask for a cardic ambulance
i wud then continue to do cpr 30 rep with 2 breaths
if it was an outcall id also contact the hotel reception inform them off the situation and ask if they had defibilator
inform them im trained to operate it if they have it and get up the room asap
incall i wud continue cpr to at least keep the heart shaking so that if a cardic driver ie the motorbike guy reaches me in under 10min he may slap on the defibs guy hopefully surivces and im due a massive mother fucking tip
also give as much info without outing myself and wave him off in ambulance
and if its incall i wud then look up daft.ie and move
ps most people show signs of a heart attack prior to heart attack pain down the left hand cold and clamy skin dizzyness etc if this was the case i wud offer my client a disprin tablet to thin the blood and ring a taxi to the nearest hosiptal!
sudden cardic arest shows signs of difficulty to take in air red to blue face!!
