Which statement best describes artificial ventilation?

• A. It involves providing oxygen via a nasal cannula
• B. It involves letting the patient breathe on their own
• C. It involves forcing air or oxygen into the lungs when the patient has stopped breathing
• D. It involves ventilating the patient with a bag-valve mask only if the patient is conscious

Answer: (C)

Artificial ventilation is actively delivering breaths to someone who cannot breathe adequately on their own. It means forcing air or oxygen into the lungs when the patient has stopped breathing or is not ventilating effectively, using devices like a bag-valve-mask. This is different from simply giving oxygen through a nasal cannula, which improves oxygen levels but doesn’t move air into the lungs. It’s also different from letting the patient breathe on their own, which involves no assisted breaths. A patient’s need for ventilation depends on their respiratory status, not just whether they are conscious; even an unconscious patient may require ventilation if they aren’t ventilating adequately. In practice, you deliver breaths with proper volume and rate to achieve visible chest rise and effective ventilation.
