Question: 1 / 400

Under what condition should tracheal suctioning be stopped?

Long duration of suctioning

Signs of hypoxia

Bradycardia

Tracheal suctioning should be stopped in instances of bradycardia. This is due to the physiological response that occurs during suctioning, which can lead to stimulation of the vagus nerve. Stimulation of this nerve may cause a decrease in heart rate, leading to bradycardia. When bradycardia is observed, it indicates that the procedure is negatively affecting the patient, making it crucial to cease suctioning to avoid worsening the patient's condition or causing further complications.

While long durations of suctioning or signs of hypoxia can also be critical considerations, bradycardia directly reflects an immediate cardiovascular response requiring prompt attention. Improvement in respiratory rate is not a valid reason to stop suctioning, as the procedure may still be necessary until the patient's overall condition stabilizes, regardless of respiratory rate.
