Benefits of Airway Clearance Devices & Techniques

New to airway clearance? If you’re living with a chronic lung condition, like bronchiectasis (brong-kee-EK-tuh-sis), breathing without feeling constricted in the airways is something you never want to take for granted. 

Though your clinician may prescribe different types of treatment to help you manage your symptoms—such as antibiotics or mucus-thinning medications [1]airway clearance works to help treat the underlying cause of your chronic symptoms (i.e., mucus buildup). 

When mucus builds up in the lungs, breathing becomes more difficult. Excess mucus can also leave your lungs more prone to infection [2] or cause you to experience a worsening of bronchiectasis-related symptoms (i.e., flare up). 

What Is Airway Clearance?

When performed regularly, airway clearance helps loosen mucus in the lungs, so it can be broken up and more easily coughed out—thereby reducing the risk of respiratory infection [3]. 

Why Is Airway Clearance Important for Managing Bronchiectasis?

Each patient will experience bronchiectasis symptoms differently, so it’s important to talk with your doctor to find an airway clearance solution that can help you improve symptoms and reduce complications associated with this chronic lung condition. 

Airway Clearance Devices vs. Techniques

Airway clearance can be performed using a hand-held device, a respiratory vest, or manually with the help of a caregiver.

To understand the different types of airway clearance devices and techniques that are available, we’ve compiled some information below, so you can take the next step in talking to your clinician about adding airway clearance to your individual treatment plan.

Breathing techniques, such as pursed-lip breathing and abdominal breathing, are performed using controlled exercises that patients can try at home to help loosen and mobilize mucus. 

According to the American Thoracic Society, a common breathing technique is known as the “huff cough.” This involves a repeated cycle of inhaling air through your nose and then exhaling it back out through your mouth—simultaneously pulling your abdomen inward and making a “huff” sound [4].

Oscillating Positive Expiratory Pressure (OPEP) are hand-held devices used to create resistance and vibrations that help loosen and clear mucus from the airways. After a series of breaths through an OPEP device, patients will “huff cough” to clear mucus from their lungs [5].

A traditional approach to airway clearance is Manual Chest Physiotherapy, also known as Manual CPT, which involves the assistance of a therapist or caregiver who manually claps on your chest wall in various positions [6]. The repeated clapping helps to loosen mucus and move it toward the larger airways. This technique is typically performed multiple times a day, using various positions to help drain mucus [7].

While this technique may be beneficial, needing a caregiver to perform manual CPT every day is not only time-consuming, but can be exhausting.

HFCWO therapy is an airway clearance device that works similarly to manual CPT, but rather than relying on someone else to help, you can perform your therapy independently. 

The SmartVest Airway Clearance System offers HFCWO therapy in a convenient and comfortable garment worn around the chest wall that is connected to a generator. Once activated, the machine performs a series of vibrating pulses that are consistent in frequency, delivery, and, on average, completed just twice a day in 20-minute sessions.

SmartVest offers 360° lung coverage and is clinically proven to clear the lungs of excess mucus, which can reduce the risk of respiratory infections and hospitalizations [8]. In addition, SmartVest releases, on average, 91% of its air between compressions [9], meaning patients have more breathing roomTM and comfort (less restriction) during therapy.

SmartVest is a convenient and comfortable approach to bronchiectasis management by helping you prevent the cycle of mucus buildup and infection.
