Hypoxia is one of the most common suctioning complications. It’s also preventable in most scenarios. Hyperoxygenate a patient prior to suctioning to reduce the risk of hypoxia as well as other suctioning complications. Here’s what you need to know about the process.
Sometimes hypoxia occurs following suctioning because the suctioning was ineffective at removing an obstruction. More frequently, suctioning itself is the culprit. During suctioning, a patient cannot breathe normally. Suctioning doesn’t just remove secretions; it also removes oxygen, and so prolonged suctioning may increase the risk of a hypoxic state.
Limit tracheal suctioning to less than 15 seconds to lower the risk. In some cases, suctioning may also stimulate the vagus nerve, triggering bradycardia, hypoxia, and even fainting. In both scenarios, hyperoxygenation before suctioning can improve outcomes.
Before oxygenating the patient, conduct an assessment to determine whether suctioning is necessary. Though there are no absolute contraindications to suctioning, no procedure—including suctioning—is risk-free. The most common indications for suctioning include:
First, wash your hands and put on a new pair of gloves before touching the patient to begin oxygenation.
The risks of hyperoxygenation are minimal, although, as you know, it is possible that oxygenation can distribute contaminants or move secretions deeper into the airway. So monitor the patient for signs of distress, and intervene if the patient begins to choke or aspirate.
Otherwise, the precautions you need to take prior to oxygenation are virtually identical to those you will use for suctioning:
Suctioning is not the end of treatment. You must continue to monitor the patient after suctioning, paying close attention to vital signs and behavior. Most agencies recommend oxygenating the patient after suctioning. This is doubly important in patients who exhibit signs of hypoxia prior to or during suctioning. Oxygenate for 60 seconds after suctioning.
Portable emergency suction machines do more than just protect the airway in an emergency situation. Hospitals may use these machines to comply with their obligations under the Emergency Medical Treatment and Active Labor Act (EMTALA) or tend to patients experiencing respiratory distress in waiting rooms or other areas that do not afford immediate access to wall-mounted suction.
In emergency situations, reliable, consistent suctioning is vitally important. The right machine quickly clears the airway without losing power. For help selecting the appropriate machine for your agency, download our free guide, The Ultimate Guide to Purchasing a Portable Emergency Suction Device.
