When Mr. Hernandez has a pulse and is unresponsive, what is the immediate step for supporting his ventilation?

In the scenario where Mr. Hernandez has a pulse but is unresponsive, the priority is to ensure adequate ventilation. Supporting his ventilation at a rate of 10 breaths per minute aligns with the guidelines for patients who are unresponsive yet maintaining a pulse. This specific rate helps provide sufficient oxygen to the lungs, ensuring that carbon dioxide is effectively removed.

The rationale behind this ventilation rate is based on the physiological needs of an unresponsive patient, who may not be adequately breathing on their own. By administering breaths at this rate, you optimize oxygenation and ventilation, helping to prevent hypoxia and ensuring his brain and vital organs continue to receive the oxygen they need.

Other options, such as ventilating at a slower rate or employing positive pressure ventilation immediately, may not adequately address the immediate need for gas exchange, especially if the patient is not initiating effective breaths on their own. Stopping all ventilation support would be inappropriate, as it would leave the patient without the necessary respiratory assistance.
