The most significant complication associated with oropharyngeal suctioning is:

• A. Nasal trauma
• B. Nausea
• C. Hypoxia due to prolonged suction attempts
• D. Sinus infection

Answer: (C)

When suctioning the oropharynx, the risk that matters most is losing oxygen to the body during the procedure. The suction device uses negative pressure to pull secretions out, but that same action can remove a portion of the air already in the lungs and reduce the patient’s oxygen saturation if you suction for too long or too aggressively. That drop in oxygen levels, or hypoxia, can occur quickly and lead to life‑threatening effects, especially in patients who are already struggling to breathe. To keep this risk low, preoxygenate when possible and limit each suction pass to a brief duration (typically around 10 seconds), then reassess and reoxygenate before the next pass. Only suction as needed to clear secretions, and use basic precautions to avoid prolonged interruptions in oxygen delivery. Other potential issues like irritation, minor trauma, or nausea can happen, but they are less dangerous than the immediate danger of hypoxia from extended suctioning.
