Obstructive sleep apnea

Article Abstract:

Sleep apnea is characterized by the cessation of breathing or abnormal decrease in breathing rate during sleep. Sleep apnea is usually caused by the narrowing of the airway, typically due to poor muscle tone, excessive fat tissue in the neck, or abnormalities of the bones of the head and face. The most common symptoms are snoring and daytime fatigue, but a proper diagnosis requires a sleep study with monitoring of various physiologic indicators. Sleep apnea increases the risk of hypertension, heart failure, stroke, and motor vehicle accidents. The most common treatment is positive airway pressure given through a mask. If appropriate, treatment may also involve reduced alcohol intake, weight loss in obese patients, and altered sleeping position. Some patients respond well to oral appliances that change the shape of the oral cavity. Medications have not been consistently effective, though surgery may be successful in cases where positive airway pressure is ineffective.

Improvement in pulmonary function and elastic recoil after lung-reduction surgery for diffuse emphysema

Article Abstract:

Lung-reduction surgery may improve exercise capability and breathing difficulties in emphysema patients by increasing the elastic recoil of the lungs. Lung reduction involves the surgical removal of the most damaged lung tissue and may avoid continued hyperinflation of the lungs. Researchers evaluated the short-term impact of surgery in 20 patients with diffuse emphysema in terms of walking for six minutes and in terms of breathing problems. Nineteen cases were related to tobacco use. Three months after surgery, elastic recoil efficiency increased in 19 patients, corresponding to the ability to walk a greater distance in six minutes. All but two patients had improved breathing scores as determined by interviews. The records of the remaining two patients indicated a subjective improvement of dyspnea as well. The surgical impact on pulmonary mechanics should be addressed with respect to short-term benefits.

Improvement of sleep apnea in patients with chronic renal failure who undergo nocturnal hemodialysis

Article Abstract:

Nocturnal hemodialysis can lower the rate of sleep apnea in patients with chronic kidney failure. Sleep apnea occurs when people stop breathing temporarily throughout the night. Nocturnal hemodialysis is an innovative form of home care that allows patients to undergo dialysis at night while they sleep.
