i have a first aid kit in my car and on bigger trips, i usually carry one in my backpack...
i learned CPR on different occassions (drivers licence, military, civil safety service) and am still able to perfom it..
they keep it fresh with sending us all tree years into rehearsel classes.. as an officer in civil safety, to know CPR is a must.
the first thirty minutes are actually the most crucial.. you approach the injured person with the so called (in german) GABI:
Gibt er Antwort? --> does he answer?
Atmet er? --> does he breath?
Blutet er? --> does he bleed?
Ist sein Puls normal? --> Can you feel a pulse and is it normal?
you check everything through with its own techniques and then assess and process the situation:
Is he unconscious but breathing, not bleeding and has a somewhat normal pulse --> you lay him on the side, stabilise him and call emergency.. make sure he keeps breathing and wont swallow his tongue of suffocate on his own thrown up...
is he conscious/unconsious but breathing, yet
bleeding and has a somewhat normal pulse --> you try to stop the bleeding with a compression.. in case of unconsciousness, you then lay him on the side and stabilise him and then call emergency..
if he is conscious, try to ask what happened so you can get the information on to the emergency guys...
Is he unconscious,
not breathing, not bleeding and has a somewhat normal pulse --> you start to give extra oxygen untill he comes back.. never ever stop it as long as he wont regularly breath by himself... the doc is the only one to make decisions...
incase he's bleeding - get somebody to compress the wound while you keep on applying respiratory help.. he needs to call emergency...
if hes unconscious, not breathing, not bleeding and the pulse is erratic --> you start CPR immediately untill he regains consiousness.. never break up CPR untill he's back to breathing and somehow awake...
if he's bleeding, get somebody to compress the wound while you keep applying CPR.. he needs to call the emergency...
One very important thing, try not to move "the patient" at all if possible... unless his live is endangered... you can never know what happened.. maybe he has broken vertebra and you moving him will severe the spinal cord...
yet, allways value his live higher than possible implication on his future health... thats why you allways concentrate on CPR although he might be bleeding pretty hard..
incase you are alone: try to CPR him for at least 3 minutes and then try get help... dont break up the CPR for longer than 30seconds, once you started.. if you need to call emergency yourself, you will need to find free seconds in between the circles..
(stuck your phone on your shoulder while compressing, make a break in talking when giving respiratory aid... )
If you call emergency, never give information you're not sure about... only tell them what you realy know.. but the more the better...
and i can only stretch it again - never ever ever ever stop CPR and respiratory aid until the doc arrives... maybe he wont be able to do anything anymore... but maybe a siringe of adrenaline will bring him back and he will survive, only because you kept up CPR..
so again, never ever break it up untill the doc sais so...
and as small additional hint: the impulses of compression are the same tempo as "staying alive" from the BeeGees...
so on every AH, AH, AH, AH you apply a compression...
i think thats pretty much it... at least what i been taught...
