Yes, if a person is already breathing there is no reason why you would need to breathe for them.
Check for adequate breathing for 10 seconds; the chest should clearly rise for breathing to be effective.
Listen for breaths from the nose and mouth of the victim. Remember: Look, Listen, and Feel.
Checking the signs of life, to determine what would you look for is:1. Look to see if the chest is rising and falling2. Listen for breaths from the mouth and nose3. Feel on your cheeks respiration's from the mouth and noseIf these are absent, there are no signs of life; check them for 10 seconds and if absent, immediately start CPR.
Adult: Tip head & check for breathing. If no breathing, give 2 breaths & start CPR 30 compressions/2 breaths. Infant & Child: Tip head & check for breathing. If no breathing, give 2 breaths. Check pulse (Infant brachial, child carotid). If no pulse start CPR 30 compressions/2 breaths.
check a carotid pulse for not less then 5, but no more then 10 seconds
Listen for breathing sounds coming out of the mouth and nose. Look for other body movements down the long axis of the body. Note skin color as well for an additional indicator. Look, listen and feel are the key points.
Once no breathing is confirmed, do not wait at all to give breaths.
That depends...if you happen upon an unresponsive victim, you need to check to see if they are breathing and if they have a pulse first. Look, listen, and feel for 10-15 seconds. If they are pulseless and apneic (not breathing) you should perform chest compressions and rescue breathing immediately, at a ratio of 30 compressions to 2 breaths, @ 100 compressions/minute. If they do have a pulse, but are apneic, perform rescue breathing only, @ 1 breath every 5 seconds. If you are alone and happen upon an "un-witnessed" collapse and you don't know how long they've been down, do CPR for 2 minutes, and then try to go for help. If the collapse is "witnessed", call for help first, then begin CPR. Source: Emergency Medical Technician
Maybe you meant "Hyperventilation" (overthreathing): The action of breathing faster and/or deeper than normal.
yes
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.
take a few deep breaths
