Can abdominal binders help COVID-19 patients?

Can abdominal binders help COVID-19 patients?

There have recently been several reports in the news [1-3] that placing ventilated COVID-19 patients in the prone position about 16 hours per day helps significantly to increase the oxygen saturation of the lungs. The explanation seems to be that sections of the lungs are being squeezed by the weight of the body when patients are on their back. Turning them on their bellies opens up these parts of the lungs for better oxygenation.

The idea of using the prone position in COVID-19 patients can be related to numerous studies [4-8] proving the benefits for patients with chronic obstructive pulmonary disease (COPD), and acute respiratory distress syndrome (ARDS), - conditions with similarities to the decreased lung function in COVID-19 patients.

However, there are disadvantages to having patients in the prone position: There could be increased risk of air-born contamination when turning ventilated COVID-19 patients in the prone position, and they require more sedation which may prolong the ICU stay. Non-ventilated and non-sedated COVID-19 patients may find it uncomfortable to be on their stomachs for 16 hours so they don’t achieve a significant increase in oxygenation.

Are there alternative ways to achieve the same positive effect on respiratory function as a prone position?
Could the answer be the use of abdominal binders?

Scientific publications have shown that breathing efficiency increases in patients with COPD when they use an abdominal binder. The positive effect on breathing when applying an abdominal binder is also documented in patients with spinal cord injuries [9-12]. If the impact on lung function in COVID-19 patients has similarities to COPD patients, it gives reason to speculate if an abdominal binder could help.

How can an abdominal binder improve breathing? The explanation is related to that intra-abdominal pressure is needed to expand the ribcage and thereby the lungs, which is why the diaphragm is an important muscle for breathing [13,14]. The diaphragm is a large dome-shaped muscle that separates the thoracic and abdominal cavities. It has a central tendon, and peripheral muscular fibers that are attached to the lower border of the rib cage - an area called the zone of apposition. During inspiration these muscle fibers contract which both flattens the diaphragm (moves it downwards) and expands the ribcage in an outwards direction. This action enlarges the pleural cavity and the lungs (breathing air in) and increases pressure in the abdominal cavity moving the abdominal wall outwards. If the abdominal wall is prevented from moving outwards, like when an abdominal binder is used, the expansion of the lower ribcage increases further, since the diaphragm with the contracting peripheral muscles attached to the ribcage is forced higher, thus improving lung expansion.

If abdominal binders can help COPD patients and if COVID-19 patients have lung conditions that are similar to COPD, can it be assumed that a similar positive effect on breathing could be achieved by applying abdominal binders to COVID-19 patients? And could it be a viable way to help to decrease a 16-hour prone position?

Qualiteam would like to donate abdominal binders to investigate whether it is possible to help COVID-19 patients to a better recovery with improved respiration. Please contact us for details at info@qualiteam.com
