Q. No.In mouth‐to‐mouth artificial respiration, the rescuer blows air from his or her own respiratory system into that of the victim. Which of the following statements are correct?
1.
expansion of the victim’s lungs is brought about by blowing air in at lower than atmospheric pressure (negative‐pressure breathing)
2.
during inflation of the lungs, the intrapleural pressure decreases
3.
expiration during this procedure depends on the elasticity of the alveolar and thoracic walls
4.
this technique will not work if the victim has a hole in the chest wall, even if the lungs are intact
