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.

 While tachycardia can be a sign of respiratory distress, it also can be a complication of interventions to treat respiratory distress, including suctioning. First responders and medical providers must have a clear understanding of the link between tachycardia and suctioning so that they can reduce the risk of patient injuries and improve both long- and short-term outcomes.  

Airway obstructions are a common emergency, especially among pediatric and geriatric patients. Choking is a common hazard and a prominent cause of childhood death and injury among children under age four, claiming at least one child’s life every few days. In the case of geriatric patients, the risk of airway obstructions due to chronic obstructive pulmonary disease (COPD), pneumonia, and airway injuries greatly increases with age. The airway also becomes more fragile as a person gets older, making it more difficult to treat airway issues. Several techniques can open an obstructed airway, but the right technique depends on the reason for the obstruction. 

Age, weak muscle tone, chronic illnesses, and changes in the throat and esophagus increase the rate of airway obstructions in the elderly. A recent study that used spirometry measures as a clinical indicator of airway obstructions in patients aged 60-93 found an obstruction rate of 22.5%.

You’re responding to a choking involving an obstruction. As you know, obstructions can be mild, making breathing difficult or painful, or they can be urgent and life-threatening, as is the case with a choking child.

Upper airway obstructions affect the trachea, pharynx, or larynx. While partial obstructions can be painful, complete obstructions can be life-threatening. Without treatment, they can quickly prove fatal.

It’s a dramatic plot twist in movies, medical dramas, and even the occasional sitcom (think MacGyver): A character is choking or in respiratory distress and standard interventions like the Heimlich maneuver just aren’t cutting it. So a heroic bystander takes things into their own hands and jams a pen into the victim’s throat, much to everyone’s horror. But then, to everyone’s shock and relief, doing so clears the airway, allowing the survivor to breathe until help arrives. But can you really do this?

Airway obstructions are common. The prevalence and type of airway obstruction varies with age. Children younger than four are more vulnerable to choking-related upper airway obstructions, while adults commonly experience airway obstruction caused by complications from smoking. First responders will inevitably encounter a wide variety of airway obstructions and must be prepared to promptly respond to each with appropriate medical care. Here are the most common causes of upper airway obstruction.

COVID-19 fundamentally changed everything about how many people live. Choices that once seemed innocuous, such as going to the dentist or the grocery store, can now expose people to a lethal virus.
