2. Platypnea - Wikipedia

   en.wikipedia.org/wiki/Platypnea

   A related condition, orthodeoxia, describes the clinical finding of low oxygen saturation in the upright position, which improves when lying down. [3] Platypnea and orthodeoxia (low oxygen levels when in upright posture) can co-exist, and this combination is named platypnea-orthodeoxia syndrome. [4] [5] The syndrome is considered extremely rare ...

3. Prone ventilation - Wikipedia

   en.wikipedia.org/wiki/Prone_ventilation

   By redistributing pulmonary blood flow, oxygen levels can increase from low ventilated areas to higher ventilation. [4] [5] [6] The physiologic mechanism can be explained by a gravity-dependent increase in pleural pressure when supine compared to prone. In the prone position, the lungs' dorsal aspects have less pleural pressure, which ...

4. Obstructive sleep apnea - Wikipedia

   en.wikipedia.org/wiki/Obstructive_sleep_apnea

   Symptoms may be present for years or even decades without identification, during which time the person may become conditioned to the daytime sleepiness, headaches and fatigue associated with significant levels of sleep disturbance. Obstructive sleep apnea has been associated with neurocognitive morbidity and there is a link between snoring and ...

5. Hepatopulmonary syndrome - Wikipedia

   en.wikipedia.org/wiki/Hepatopulmonary_syndrome

   In medicine, hepatopulmonary syndrome is a syndrome of shortness of breath and hypoxemia (low oxygen levels in the blood of the arteries) caused by vasodilation (broadening of the blood vessels) in the lungs of patients with liver disease. Dyspnea and hypoxemia are worse in the upright position (which is called platypnea and orthodeoxia ...

6. Platypnea-orthodeoxia syndrome - Wikipedia

   en.wikipedia.org/wiki/Platypnea-orthodeoxia_syndrome

   Platypnea–orthodeoxia syndrome is a rare medical condition in which a person has shortness of breath and low oxygen saturations when upright (platypnea and orthodeoxia), but no symptoms when lying down. It can be caused by ventilation-perfusion mismatch, intracardiac shunting, or pulmonary shunting. In some cases, the cause is multifactorial ...

8. Intracranial pressure - Wikipedia

   en.wikipedia.org/wiki/Intracranial_pressure

   The headache is classically a morning headache that may wake the person up. The brain is relatively poorly supplied by oxygen as a result of mild hypoventilation during the sleeping hours leading to hypercapnia and vasodilation. Cerebral edema may worsen during the night due to the lying position. The headache is worse on coughing, sneezing, or ...
