What primary method is used to assist with Don Johnson's breathing?

The correct answer is the simple face mask, which is commonly used to provide supplemental oxygen to patients who are experiencing difficulty breathing but do not require advanced airway management. A simple face mask covers the nose and mouth and allows for the delivery of oxygen at a moderate flow rate, making it suitable for patients who need some assistance with their breathing but are still maintaining their own airway and adequate oxygenation.

In many medical situations, the simple face mask can provide enough oxygen to help patients with mild respiratory distress without being invasive. It is typically used when patients require a higher concentration of oxygen than can be delivered by a nasal cannula but do not need the higher flow rates associated with a non-rebreather mask.

Choosing the simple face mask for Don Johnson indicates that his condition might not be severe enough to require more invasive measures like an endotracheal tube, which is typically used in emergency or critical care scenarios for patients who cannot breathe on their own. Other options, such as a non-rebreather mask, are designed for situations where a higher concentration of oxygen is required, and while effective, they may be more than what is necessary for cases with mild breathing difficulty.

Selecting a nasal cannula would provide low-flow oxygen, but in scenarios where a simple
