Which oxygen delivery method typically requires monitoring of the patient's breathing status?

The bag-valve-mask resuscitator is designed for delivering positive pressure ventilation to patients who are not breathing or are in respiratory distress. This method requires careful monitoring of the patient's breathing status because it involves both delivering oxygen and ensuring that the airway is secured and adequately protected. When using a bag-valve-mask, the rescuer must assess the chest rise and fall to confirm proper ventilation. This real-time feedback is crucial for avoiding complications, such as gastric inflation or inadequate ventilation, making ongoing monitoring essential.

In contrast, other oxygen delivery methods, like the non-rebreather mask, nasal cannula, and standard mask, primarily supplement oxygen rather than ventilate the patient actively. While it's important to pay attention to a patient's status with all oxygen delivery devices, the active nature of ventilating with a bag-valve-mask makes the need for continuous monitoring particularly critical in ensuring the patient's safety and the effectiveness of the ventilation.
