Quadriplegia, also known as tetrapalegia, is the loss of voluntary movement and sensation in all four extremities, and usually results from a cervical spinal cord injury (SCI). Other conditions, such as a brain stem lesion or spinal meningitis, may also result in quadriplegia. After the patient is neurologically and orthopedically stable and cannot be weaned from mechanical ventilation, a diaphragm pacing system should be considered.

UPDATE: Loving Life in California with the Avery Diaphragm Pacemaker


At age 4, Nicole was in a motor vehicle accident.  As a result, she became a C3/C4 level quadriplegic.  She was vent dependent for 7years and at age 11 wound up in the hospital with pneumonia.  This is when her and her family first learned of the Avery Diaphragm Pacemaker.  She was then implanted in [...]

Spinal Cord Injury and Breathing


There are an estimated 288,000 people living with spinal cord injuries in the United States alone, with an estimated 17,700 new cases each year. In many of these cases, breathing assistance is required. There are multiple options available, though many people, including physicians, are not always aware of the options that are available. For quadriplegic [...]

While an injury at the C5 vertebrae or lower typically does not affect breathing, injuries above the C4 do often require ventilatory assistance. Individuals with injuries at the C1 and C2 level are dependent on assistance for breathing. Typically, [...]
