Suctioning the Nasopharyngeal Airway
4.5K
Nasopharyngeal suctioning is a procedure to remove secretions from the upper part of the respiratory tract that the patient cannot clear independently. It helps maintain airway patency and prevents complications such as aspiration pneumonia.

Administering Oxygen by Nasal Cannula
4.2K
Oxygen therapy is critical to patient care, especially for those struggling with respiratory issues. This intervention increases the oxygen concentration in the lungs, enhancing the amount of oxygen transported to the body's tissues. One standard method of delivering supplemental oxygen is through a nasal cannula, a non-invasive device that provides low to medium oxygen concentrations.

Suctioning the Oropharyngeal Airway

In preparing for oropharyngeal airway suctioning, a nurse must gather all necessary equipment, including a suction unit with tubing, a prepackaged suction kit, sterile gloves, water or saline for irrigation, a water-soluble lubricant, and additional personal protective equipment (such as a gown, mask, and goggles) to control infections.
After assembling the equipment, the nurse should practice hand hygiene and don appropriate PPE according to infection control guidelines to avoid the...
