Understanding Diaphragm Paralysis and What Can Be Done
The diaphragm is a muscle crucial for breathing. When the diaphragm contracts, suction is created that draws air into the lungs. Air is exhaled as the diaphragm relaxes, in combination with other muscles and tissues. When the diaphragm is not working properly, respiratory issues may occur. There is typically a degree of reduction in lung capacity, particularly noticeable when lying down (source: Cedars-Sinai).
If it is suspected that the diaphragm is not working correctly, there are a number of tests that may be performed. These include chest x-rays, blood tests, phrenic nerve stimulation testing, MRI and ultrasound. A physician will be able to give specific information on the best test for your specific symptoms.
Treatment for Diaphragm Paralysis
Treatment of diaphragm paralysis differs, depending on the severity of the condition. In most unilateral cases of diaphragm paralysis, no treatment is needed. In more severe cases, modalities such as diaphragmatic pacing or plication of the diaphragm may be used. In bilateral diaphragm paralysis or in patients with ventilator failure, continuous positive airway pressure or mechanical ventilation and tracheostomy are generally needed (information from National Institutes of Health).
For cases of diaphragm paralysis where breathing function is severely limited, many patients have two options: mechanical ventilation or diaphragm pacing.
In mechanical ventilation, often known as positive pressure ventilation (PPV), a machine called a ventilator is used to push air into the lungs. Though this may be a life-saving intervention, it may also cause problems such as ventilator-assisted pneumonia, collapsed lungs, and airway injuries. The diaphragm may also atrophy, as it becomes a virtually unused muscle.
Diaphragm Pacing utilizes a surgically implanted phrenic nerve stimulator to deliver electrical impulses to the diaphragm, causing it to contract and expand. This creates a more natural breathing pattern. There are many advantages to diaphragm pacing over mechanical ventilation including both health and quality of life benefits. Advantages of diaphragm pacing are discussed in more detail in our articles discussing diaphragm pacing systems for quadriplegia and Diaphragm Pacing System advantages.

Diaphragm Pacing Systems
The Avery Diaphragm Pacing System is a Diaphragm Pacemaker manufactured by Avery Biomedical Devices, and is used for patients with diaphragm paralysis who would otherwise be completely or partially dependent on mechanical ventilation.
For more information, or to see if you are a candidate for diaphragm pacing, please call us at 631-864-1600 or fill out our request information form.
The Avery Diaphragm Pacing System System is the only diaphragm-pacing device with full pre-market approval from the USFDA and CE marking privileges under the European Active Implantable Medical Device Directive for adult and pediatric use. In addition, its system of using small implanted radiofrequency receivers rather than electrode wires that pass directly through the skin may decrease a patient’s risk of infection and ongoing wound care management issues.
Avery has been commercially distributing diaphragm pacing systems since the early 1970s. Since then, more than 2,000 patients have been implanted in over 40 countries establishing an unsurpassed record of safety and reliability.
