nationwide experience obstructive sleep apnea, and at least that many polio survivors
do. (Many sleep specialists think these estimates may be too low.)
Survivors also can have central sleep apnea (CSA), a condition in which the brain
temporarily “forgets” to signal breathing muscles to take a breath. This is evident dur-
ing a sleep study when there is no chest movement for at least 10 seconds, indicating
that the individual is not breathing. Some people have mixed sleep apnea, which is a
combination of OSA and CSA.
The solution for those with only obstructive sleep apnea is a CPAP machine – a
machine that continuously blows in air through a mask worn at night or during sleep.
This constant airflow keeps the airway open, so one can breathe easily.
Polio survivors who have central or mixed sleep apnea or significant respiratory muscle
weakness use a bi-level device (one that blows air in at a certain pressure when inhaling
and at a lower pressure when exhaling through a mask over the mouth or nose). Others
use a volume ventilator or one of the newer multi-mode devices. There is a wide variety
of masks and breathing devices available on the market. Experienced pulmonologists
and respiratory therapists can assist in obtaining the correct treatment and equipment.
Although your parent or loved one may not have breathing or sleep problems when
initially checked, periodic testing is important because such problems may develop
over time.
They may begin to complain of difficulty swallowing. Complaints include food sticking
in the throat, difficulty swallowing pills, coughing spells during eating, food backing
up from the throat, taking longer eating a meal and unintentional weight loss.
Because many of the muscles and nerves that control swallowing also control speech
and voice, changes that make swallowing more difficult may also make speech more
difficult, and quieter and harder to hear by others.
Swallowing problems that put a person at risk for aspiration – where food enters the
airway instead of the stomach – can result in bronchitis and pneumonia. The two pri-
mary tests for checking swallowing are the modified barium swallow and a fiberoptic
swallowing examination of the throat. Your parent’s primary physician or pulmonolo-
gist can refer them to a speech-language pathologist (someone who specializes in
swallowing problems, referred to as dysphagia) at a hospital or a rehabilitation center
for evaluation and treatment.
