Breathing and airway - initiation of cpr, Biology


Place the patient  supine on a firm  surface with his  head at level  or  slightly lower than the level of heart. Immediately, clear the  airway and start  rescue breathing.  In  an  unconscious patient the  base of  the tongue  falls  back to obstruct the airways. For  this, combination of head tilt and  chin lift should be employed  to open  the  airways. In  this method the flat of  the hand  is placed  on the forehead  and pressure  is applied to  tip the  patient's head maximally backward.

Chin can  be lifted forward with  the other hand placing the fingertips under the mandible near the protruberance  of  the chin, bringing the chin forward while supporting the jaw. Oral cavity should be cleared  of  all secretions.  


If after  opening the airway child is still not  breathing or having gasping respiration, rescue breathing should be started. Place your mouth over  the mouth of  the baby  to make  a  tight seal.  In  infants, nose can also be included while in the older children nose can be  pinched. Two slow breaths are delivered  in  succession each lasting for  1-1%  second. This helps  to check  if there  is any  airway obstruction as well as helps in  opening of  collapsed alveoli. Amount of  air deliveted should cause adequate rise  in  chest wall.

 If  chest wall does not rise, airway obstruction due  to  inflammatory swelling, mucous plug or foreign body should be suspected. In such  a case, readjust at head tilt and lifting of  chin  and  repeat rescue breathing with greater pressure and volume;  if still not  successful, suspect foreign body.
