What should you do if someone sustains a head injury and has difficulty breathing?

When someone sustains a head injury and exhibits difficulty breathing, the most appropriate course of action is to call emergency services and monitor their breathing. This response is crucial as head injuries can lead to serious complications, including potential airway obstruction or swelling that affects breathing. By contacting emergency services, you ensure that professional medical help is on the way, as they can provide the necessary intervention and advanced care.

Monitoring the individual's breathing is equally important because it allows you to assess whether their condition is worsening. If they become unresponsive or their breathing deteriorates, you may need to perform CPR if you are trained and it is appropriate to do so, but waiting for emergency responders to arrive while keeping an eye on their breathing is a prudent approach in this scenario. This option prioritizes safety and the well-being of the individual while ensuring that help is on the way.
