Pursed-lip breathing increases positive pressure generated in the conducting branches of the lungs. [4] This can hold open bronchioles in patients with high lung compliance, such as those with emphysema. [4] Pursed-lip breathing also accesses the parasympathetic nervous system, which reduces stress during episodes of shortness of breath. [5]
Children with obstructive sleep-disordered breathing also show a faster heart rate during wakefulness and during sleep. [74] In adult patients, OSA has been shown to be associated with insulin resistance. [75] In children, metabolic consequences of OSA are complicated to assess as they can also be associated to puberty and obesity (if present ...
The Wisconsin Sleep Cohort Study, a longitudinal study of the natural history of obstructive sleep apnea (OSA), found that of a random sample (602 employed men and women, 30–60 years old) the prevalence of OSA (5 or more events/hr) was 9% for women and 24% for men. However, the study found that among sleepy patients in this group, 2% of women ...
Sleep apnea is a common sleep disorder that affects more than 20 percent of people in the United States. It happens when your breathing temporarily stops while you sleep. Depending on the severity ...
The application of positive pressure may be intended to prevent upper airway collapse, as occurs in obstructive sleep apnea, or to reduce the work of breathing in conditions such as acute decompensated heart failure. CPAP therapy is highly effective for managing obstructive sleep apnea.

A sleep study is a test that records the activity of the body during sleep. There are five main types of sleep studies that use different methods to test for different sleep characteristics and disorders. These include simple sleep studies, polysomnography, multiple sleep latency tests (MSLTs), maintenance of wakefulness tests (MWTs), and home ...
Rapid breathing helps the patient compensate for the decrease in blood pH by increasing the amount of exhaled carbon dioxide, which helps prevent further acid accumulation in the blood. [11] Cheyne–Stokes respiration is a breathing pattern consisting of alternating periods of rapid and slow breathing, which may result from a brain stem injury ...
