Question: 1 / 400

Which of the following is NOT a means of delivering oxygen to a patient?

nasal cannula

mechanical ventilator

chest tube

The chest tube is primarily used for the drainage of fluid or air from the pleural space, which can help in treating conditions like pneumothorax or pleural effusion. Its main function is not related to the delivery of oxygen.

In contrast, other options like a nasal cannula, mechanical ventilator, and non-rebreathing mask are all designed specifically to administer oxygen to patients in different situations, depending on their needs. A nasal cannula provides low-flow oxygen for patients who require mild respiratory support. A mechanical ventilator assists or takes over the breathing process for patients who are unable to breathe independently, delivering controlled amounts of oxygen. Similarly, a non-rebreathing mask is used to deliver high concentrations of oxygen to patients who need significant respiratory support.

Thus, the chest tube stands out as the only option that does not deliver oxygen, confirming it as the correct answer to the question.
