| If left untreated, acute pulmonary edema can lead to [[coma]] and even death, generally due to its main complication of [[Hypoxia (medical)|hypoxia]].

| ==Cardiac Catheterization== | | ==[[Pulmonary edema overview|Overview]]== |
| Insertion of a [[pulmonary arterial catheter]] (a.k.a. a [[Swan-Ganz catheter]]) may be required to distinguish between the two main forms of pulmonary edema and to help guide management<ref name=Ware/>. In patients with cardiogenic pulmonary edema the pulmonary artery pressure will be elevated. Among patients with non-cardiogenic pulmonary edema the wedge pressure will not be elevated.

| ===Acute Pulmonary Edema=== | | ==[[Pulmonary edema classification|Classification]]== |
| In patients with acute pulmonary edema, the goal is to reduce both [[preload]] and [[afterload]] and to [[diurese]] the patient. Intravenous nitroglycerin can be used to reduce both the preload and afterload. Diuretics such as [[furosemide]] or [[bumetanide]] can be used to reduce volume overload. The dose that the patient is on chronically should be doubled and administered intravenously in the setting of flash pulmonary edema. [[Morphine sulfate]] may be helpful in reducing the drive to breathe, improving patient comfort, and reducing the [[preload]].

|
| Oxygen therapy is required to minimize [[cyanosis]] and to maintain adequate oxygenation. High-flow oxygen, noninvasive ventilation (either [[continuous positive airway pressure]] (CPAP) or variable positive airway pressure (VPAP) may be effective<ref>Masip J, Roque M, Sanchez B, Fernandez R, Subirana M, Exposito JA. Noninvasive ventilation in acute cardiogenic pulmonary edema: systematic review and meta-analysis. ''JAMA'' 2005;294:3124-30. PMID 16380593.</ref><ref>Peter JV, Moran JL, Phillips-Hughes J, Graham P, Bersten AD. Effect of non-invasive positive pressure ventilation (NIPPV) on mortality in patients with acute cardiogenic pulmonary oedema: a meta-analysis. ''Lancet'' 2006;367(9517):1155-63. PMID 16616558.</ref>). If the simple measures are not effective then [[mechanical ventilation]] may be required.

|
| Treatment should also be directed at managing the underlying cause of an episode of acute pulmonary edema. This would include managing as [[acute myocardial infarction]], [[mitral regurgitation]], [[aortic regurgitation]], or any other condition that causes an increase in left ventricular filling pressures.

| Reoccurrence of FPE is thought to be associated with [[hypertension]]<ref>Kramer K, Kirkman P, Kitzman D, Little WC. Flash pulmonary edema: association with hypertension and reoccurrence despite coronary revascularization. Am Heart J. 2000 Sep;140(3):451-5. PMID 10966547.</ref> and may signify [[renal artery stenosis]].<ref>Pickering TG, Herman L, Devereux RB, Sotelo JE, James GD, Sos TA, Silane MF, Laragh JH. Recurrent pulmonary oedema in hypertension due to bilateral renal artery stenosis: treatment by angioplasty or surgical revascularisation. ''Lancet'' 1988;2(8610):551-2. PMID 2900930.</ref> Prevention of reoccurrence is based on managing hypertension, coronary artery disease, renovascular hypertension, and heart failure.

|
| |
|
| A 69-year-old male with well-controlled Type I [[diabetes mellitus]] (insulin-dependent) presented with upper abdominal and lower [[chest pain]] of four hours duration and accompanied by [[shortness of breath]] and [[diaphoresis]].
| | ==Diagnosis== |
|
| |
|
| An [[electrocardiogram]] revealed multiple [[premature ventricular contraction]]s (PVCs).

|
| The hospital course was characterized by recurrent [[pulmonary edema]] and [[oliguria]].
| | ==Treatment== |
| | |
| The terminal event was [[cardiac arrest]].
| |
| | |
| ===Autopsy Study=== | |
| | |
| Significant findings at postmortem examination were old and recent [[myocardial infarction]]s and evidence of [[congestive heart failure]].
| |
| | |
| The right and left lungs weighed 950 grams and 750 grams, respectively, and were reddish-brown.
