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 |
