after doing your required 30 compressions (in one person CPR) you have to give two rescue breaths. each one of the rescue breaths should be given over 1-2 seconds.
Give rescue breaths until help arrives, they start breathing on their own, you need to start CPR, the scene becomes unsafe, or you are too tired to continue.
You should give just enough air to cause chest rise. A typical breath should take no more than one to two seconds.
15 times a minute:
Give 1 breath every 3 seconds.
5-6
A rescue breath for a child should last 1 second.
A rescue breath is 1 second long.
3 breaths for children, 5 breaths for adults.
About 1 second as this is how long it would take to exhale the breath.
As long as I safely could for as long as they are responding till they can breath on their own, relief arrives, or they are dead.
You do not check for signs of circulation as a first aider, if they are not breathing then you perform 30 compresions at a rate of 100/minute followed by 2 rescue breaths regardless of whether they have signs of circulation (In a chilld you would also perform 5 rescue breaths before you start CPR). this is because even if they have circulation, if they're not breathing then they won't have circulation for long and CPR will do less harm than thinking there are signs of circulation when there aren't and not performing CPR.
Rescue breaths are no longer generally in use. Rapid chest-pressure respiration is now recommended as being more effective. But, if it turns out that you must do rescue breathing, blow a breath of air into the victim until her chest raises 2 inches or so, then immediately let the air out. If you meant for how long to keep doing rescue breathing, you only stop when the victim starts breathing on his own, or you are just too exhausted to continue.
Each breath should last 1 second; rescue breathing for a child and infant is 1 breath every 3 seconds. For adults if no signs of life go directly to CPR 30 compressions to 2 breaths.
no, it improves it for a short period of time, but should not be used as a long term replacement for brushing your teeth!
Each breath should take about 1 second.
I leaned over to catch my breath. The long run had made me tired.
Give the breath over a period of 1 second.You do this until you simply are to exhausted and unable to do it any longer.There is no time limit.You do this until proper help (rescuers) arrive.If person starts breathing by his own strength, then you stop, but you monitor until help arrives.If a person get only a little bit of oxygen all the time from you assisting breathing, then this can be worth gold when rescuers arrives.This prevents brain damage for one, and is the one main reason to carry on until rescuers arrive.Heart may have stopped too, so applying heart compression could be an addition to the situation.Learn how, it might be saving a life.
