aid method for
autonomous breathing stops
when. By hand or mechanical device to make the air there is a rhythm into the lungs, and then use the thorax and
lung elastic
recoil force makes
the gas
breathed into the
lungs. So go round
and begin again to
replace the spontaneous breathing. The heart and the
brain needs a continuous supply of oxygen. If the interruption of oxygen for 3 to
4 minutes can
cause irreversible
damage. So in some accidents, such as electric shock, drowning, cerebrovascular and cardiovascular accident, once discover heartbeat and breath stop, the first rescue measures is the rapid artificial respiration and
chest compressions, in order to maintain the effective ventilation and blood circulation, ensure the important organs of oxygen gas supply. The site can use the mouth
to mouth rescue
breathing (nasal) method, or the use of simple breathing sac. In the hospital to
rescue respiratory arrest patients can also use the
structure is more complex, the function more perfect ventilator. In the mouth to
mouth resuscitation, make the patient supine on
the ground or
hard, arms at the side close to the body, with a handkerchief to the foreign body in the mouth, one hand on the forehead, the
other hand index
finger and middle finger on the chin bone, lift the chin, the head back, so that the wall separation of tongue and pharynx, covering the epiglottic cartilage tracheal opening up to smooth, upper respiratory tract. The mouth to mouth, press on the forehead hand thumb and index finger pinching the nose, mouth to nose blowing, you can lift the chin in hand, instead of index finger, thumb, index finger closed lips, the rescue as a deep breath, leaning over to lips surrounded disease population (nose), forced to slow exhale, the air into the lungs. When blowing should see thoracic expansion. Each time the blowing time is about 1 ~ 1.5 seconds, volume 800 ~ 1000 ml is appropriate, to start the first ~ 2 times amount can be more. Each blow, remove the lips, let patients with thoracic lung gas to indent, repeat blowing, about 12 times per minute, each blowing with deep inspiration to the first part of the breath, in order to ensure the
highest oxygen
concentration; every 5 to 10 seconds, the touch of common carotid artery of patients such as pulse, the pulse disappeared also, the chest can't hear the heartbeat, namely, external cardiac massage and artificial respiration, alternately; every 2 times after blowing, with 80 ~ 100 times the frequency of external cardiac massage 15 times. Artificial respiration and cardiac massage alternately 4 times, check the carotid pulse, if the restore the beating heart, breath does not appear, continue artificial respiration. If two people, a people to do artificial
respiration, one external cardiac massage, blowing and massage adjustable ratio is 5 ∶ 1. (Appendix: new research suggests, is more effective than blowing press, the press of blowing ratio both double or single are changed to 15:1) rescue scene at the same time, shall promptly notify the professional rescue personnel to aid, or rushed to hospital for
treatment.追问是你自己答的，还是网上找的？ 如是网上找的，能提供网址吗

When we blow the breath into the person's lungs, because we are facing that person's chest, we can see his/her chest is rising as you blow in, and fall as you stop.
自己打的，很辛苦呢=。 =追问thanks
