Suctioning is generally needed for which of the following devices?

Suctioning is primarily associated with ventilators because these devices are used to assist or take over the breathing process for patients who are unable to breathe adequately on their own. When a patient is on a ventilator, secretions can build up in the airway, which can lead to blockages or complications such as pneumonia. Regular suctioning helps to keep the airway clear, ensuring that the ventilator can effectively deliver the necessary breaths to the patient.

In contrast, nebulizers, oxygen tanks, and CPAP machines do not typically require suctioning. Nebulizers are used to deliver medication in aerosol form to the lungs, oxygen tanks provide supplemental oxygen, and CPAP machines help keep the airways open during sleep without the need for suctioning to clear secretions. Thus, the ventilator is the device most commonly associated with the need for suctioning to maintain airway patency and facilitate effective ventilation.
