Paroxysmal nocturnal dyspnea is a serious medical symptom that can develop into worsening conditions. Many tests can be done in order to evaluate the cause of paroxysmal nocturnal dyspnea. Because it is commonly associated with heart failure, tests that may be run mainly focus on measuring the function and capability of the heart.
If this too is ineffective in increasing oxygen levels, the addition of oxygen therapy may be necessary. As a last resort, tracheostomy may be necessary; this involves making a surgical opening in the trachea to bypass obesity-related airway obstruction in the neck. This may be combined with mechanical ventilation with an assisted breathing ...
Without intervention, both may lead to decreased oxygen in the blood , elevated carbon dioxide level in the blood (hypercapnia), inadequate oxygen perfusion to tissue , and may be fatal. Respiratory arrest is also different from cardiac arrest, the failure of heart muscle contraction. If untreated, one may lead to the other.

Hypopnea is typically defined by a decreased amount of air movement into the lungs and can cause hypoxemia (low levels of oxygen in the blood.) It commonly is due to partial obstruction of the upper airway, but can also have neurological origins in central sleep apnea.
Apart from the specific condition of obstructive sleep apnea, other causes of snoring include alcohol intake prior to sleeping, stuffy nose, sinusitis, obesity, long tongue or uvula, large tonsil or adenoid, smaller lower jaw, deviated nasal septum, asthma, smoking and sleeping on one's back. Primary snoring is also known as "simple" or "benign ...
If reductions in ventilation are associated with sufficiently low blood-oxygen levels or with sufficiently high breathing efforts against an obstructed airway, neurological mechanisms may trigger a sudden interruption of sleep, called a neurological arousal. This arousal can cause an individual to gasp for air and awaken. [51]
Shortness of breath (SOB), known as dyspnea (in AmE) or dyspnoea (in BrE), is an uncomfortable feeling of not being able to breathe well enough. The American Thoracic Society defines it as "a subjective experience of breathing discomfort that consists of qualitatively distinct sensations that vary in intensity", and recommends evaluating dyspnea by assessing the intensity of its distinct ...
