| '''Orthopnea''' (Greek from ''ortho'', straight + ''pnoia'', breath) is [[dyspnea]] which occurs when lying flat, causing the person to have to sleep propped up in bed or sitting in a chair. Orthopnoea is a symptom of [[heart failure]]. It can also occur in those with [[asthma]] and chronic [[bronchitis]], as well as those with [[sleep apnea]] or [[panic disorder]]. The condition is often due to [[left ventricular failure]] and/or [[pulmonary edema]]. It is also associated with [[Polycystic Liver Disease]].
| | == [[Orthopnea overview|Overview]] == |
| | |
| Patients with orthopnoea often complain of waking up suddenly during the night 'unable to breathe' if they have slipped down from their pillows into the supine position. They may run to the window to 'get some air'.
| |
|
| |
|
| It is commonly measured according to the number of pillows needed to prop the patient up to enable breathing (Example: "3 pillow orthopnea").

|
| See also: [[Paroxysmal Nocturnal Dyspnea]] which means that a patient wakes up short of breath.

| == Epidemiology and Demographics == | | == [[Orthopnea pathophysiology|Pathophysiology]] == |
| Orthopnea indicates [[heart failure]] in almost 95% of cases.
| |
|
| |
|
| ==Pathophysiology== | | == [[Orthopnea causes|Causes]] == |
| When a patient lies flat, pulmonary and venous pressure increases due to increase in venous return to the lungs.

| Othopnea is often observed among patients with [[left heart failure]] the causes of which are included in the list below.
