Medical suction is the combination of vacuum pressure and airflow used to remove fluids and particulates from a patient's airway. While the goal is not to remove air itself, airflow is the mechanism that entrains and moves both fluids and solids. Understanding the relationship between vacuum and flow is critical for effective airway management, and clinicians must prioritize learning how vacuum and airflow affect medical suction to ensure patient safety.

Key Takeaways

• Medical suction functions through the combined mechanical forces of vacuum pressure and consistent airflow.

• Airflow serves as the essential mechanism for entraining and transporting both liquid and solid particulates.

• Effective airway management requires both vacuum power for movement and airflow for material entrainment.

• Clinical suctioning efficiency depends on the device's ability to gather contaminants from the surrounding area.

• Successful resuscitation relies on the timely removal of inconsistent airway materials to restore oxygen supply.

 Invented in 1907 by Dr. Sidney Yankauer, the Yankauer suction tip has withstood the test of time. The Yankauer suction tip was originally designed to remove blood and secretions from a patient’s oral airway during tonsillectomy procedures. Many practitioners call the Yankauer a “tonsil tip” suction device for this reason. 

Ask any emergency responder, and they'll tell you the critical role portable suction plays in maintaining airway patency. No other tool can remove blood, vomit, or sputum from the airway, or allow you to visualize the cords before intubation. 

 Although many first responders express reservations about airway suctioning, it is a potentially life-saving procedure that, when performed correctly, has a low risk of complications. With both cold and flu season and allergies causing year-round respiratory issues, it is always a great time for first responders to brush up on their airway management skills. Continuing education classes and regular drills can prepare you to manage even difficult airways. It’s equally important to be mindful of the main complications of suctioning. Awareness of these potential complications can guide your technique while encouraging your team to remain vigilant and diligent. 

 The patient has suffered a gunshot wound to the chest, and his blood pressure is dangerously low. You’ve covered the entry wound to prevent a sucking wound, but the patient is exhaling copious bloody froth. You successfully intubate the patient and are bagging, with good chest rise, but the bloody froth continues to interfere with air exchange. It’s time to suction the tube.  

In prehospital and emergency settings, oral suctioning may be overlooked as a basictask that is performed without harm to the patient. The reality is, oral suctioning is not without its risks and complications. In addition to complications related to the procedure itself, oral suctioning complications may arise because of ineffective or incorrect technique. Let’s explore the various oral suctioning procedure complications and discuss ways you can prevent them in your patients.

Users of battery-powered portable suction devices often comment that it “sucks”. This can be interpreted in two ways: either negatively or positively. When the negative sentiment applies, there’s no need to despair or throw the unit across the room.

A hospital visit can save a patient’s life. It can also destroy it if they pick up a virulent healthcare-associated infection (HAI). The Centers for Disease Control and Prevention (CDC) estimates that on any given day, 1 in 31 hospital patients has at least one HAI.
