What is the purpose of hyper-oxygenating a client before suctioning a trach tube?

Hyper-oxygenating a client before suctioning a trach tube is performed primarily to prevent hypoxia during the suctioning process. When suctioning, there is a risk that the client's oxygen levels may drop due to a combination of factors, such as the removal of secretions and the temporary interruption of airflow while the suction catheter is in place. By ensuring that the patient is adequately oxygenated beforehand, healthcare providers can help to maintain adequate oxygen saturation levels, thereby minimizing the risk of oxygen deficiency during the procedure.

This practice is especially important for patients with compromised respiratory function, as suctioning can lead to an increased demand for oxygen in the lungs just when the airway is being cleared. Hyper-oxygenation can involve either the administration of supplemental oxygen before the procedure or the use of specific techniques to increase oxygen availability, ensuring the patient's safety and comfort during the suctioning process.
