Red Cross Adult, Child and Baby First Aid/CPR/AED Practice Test

When administering CPR, providing a breath that is too forceful can lead to a couple of concerning outcomes, but the primary issue is that the chest may not rise effectively. This indicates that the air is not being delivered properly into the lungs, which is essential for effective ventilation. If the air is forced in too aggressively, it can lead to inadequate pressure and uneven distribution of the air, preventing the necessary rise of the chest that signals effective breathing.

While the other outcomes, such as vomiting and airway obstruction, can potentially occur due to forceful breaths, they are not the primary immediate concern in relation to the effectiveness of CPR. Furthermore, while an increase in heart rate can occur during CPR, it is not a direct result of giving a breath that is too forceful. The priority is always to ensure that breaths are delivered at a gentle, controlled rate to allow for sufficient air exchange in the lungs without causing complications.
