Acute pulmonary edema is a pathological condition defined by the presence of large amounts of fluid in pulmonary alveoli and in pulmonary interstitium. Cardiogenic acute pulmonary edema by decreasing blood evacuation from the left atrium: atrial fibrillation, acute mitral regurgitation, mitral stenosis, thrombus or myxoma in the left atrium. Cardiogenic acute pulmonary edema caused by left ventricular diastolic dysfunction: aortic stenosis, hypertension, hypertrophic cardiomyopathy, acute myocardial ischemia.
Cardiogenic acute pulmonary edema caused by left ventricular systolic dysfunction: acute myocardial ischemia, myocarditis, dilated cardiomyopathy, heart failure.
Increased capillary permeability (acute respiratory distress syndrome): pneumonia, aspiration syndrome, inhalation of toxic gases, disseminated intravascular coagulation, anaphylaxis shock, acute pancreatitis.
Incompletely understood causes: altitude acute pulmonary edema, neurogenic acute pulmonary edema, eclamsie, post anesthesia and post cardio-conversion. Cardiogenic acute pulmonary edema is caused due to the increase pulmonary capillary pressure from 8-12 mm Hg (normal) to over 18 mm Hg.
The main symptoms of acute pulmonary edema are the shortness of breath, cough, marked anxiety, cold and increased sweating and symptoms of the background heart disease.
Dyspnea is very intense, may occur in a patient who had until then no charge of this symptom (for example, a acute pulmonary edema that occurs after the onset of a myocardial infarction), or can overlap with the symptoms of preexisting heart failure . A patient that is restless, anxious or confused with sweaty, pale or mottled skin, with central type cyanosis, the patient is breathing typically standing at the edge of the bed and using accessory respiratory muscles.
Marked dyspnea, possibly vesicular murmur and prolonged expiration, rales crackles, of which level increases from the bases of the lungs to tops and can include the entire lung field. Tachycardia, hypertension or hypotension and, depending on the case, rhythm disturbances or different heart murmurs. In some cases, may appear signs of right heart failure: hepatomegaly, jugular turgor, hepato-jugular reflux, lower limb edema.
Echocardiography can detect the presence of valvulopathies, of thrombus or myxoma in the left atrium, impaired function of the left ventricle. Positive diagnosis of cardiogenic acute pulmonary edema is relatively simple, it is based on patient history and symptoms. General measures: keep the patient in a sitting position, administration of oxygen on mask or nasal tube, dyspnea sedation with morphine. Furosemide, administrated intravenous in dose of 80-120 mg or more, divided into four doses of 40 mg, each, is the primary mean of treatment of cardiogenic acute pulmonary edema. Nitroglycerin, vasodilator with rapid effect, administrated sublingual (0.5 mg tablets, the dose can be repeated in 5-10 minutes) or intravenously, in the conditions of systolic blood pressure higher than 100 mm Hg.
Administration of digoxin can bring benefits by improving the cardiac tonus or by decreasing the heart rate in case of atrial fibrillation.
Other therapeutic measures in cardiogenic acute pulmonary edema are: miofilin administration or the administration of angiotensin converting enzyme inhibitors, assisted ventilation, circulatory support with counterpulsation balloon and the treatment of the cause that led to the installation of cardiogenic acute pulmonary edema. Angioedema is a swelling, similar to hives, but the swelling is beneath the skin rather than on the surface. The accumulation of fluid within the air gaps of lungs and parenchyma is called Pulmonary Edema. The overwhelming symptom of pulmonary edema is difficulty breathing, but may also include coughing up blood (classically seen as pink, frothy sputum), excessive sweating, anxiety, and pale skin.
There is no one single test which confirms that breathlessness is caused by pulmonary edema, indeed in many cases the causes of shortness of breath are probably multifactorial.
Low oxygen saturation and disturbed arterial blood gas readings support the proposed diagnosis by suggesting a pulmonary shunt. Urgent echocardiography, if available, may strengthen the diagnosis especially in cardiogenic pulmonary edema by demonstrating impaired left ventricular function, high central venous pressures and high pulmonary artery pressures.

Blood tests are performed for electrolytes (sodium, potassium) and markers of renal function (creatinine, urea). Pulmonary edema is an accumulation of fluid within the parenchyma and air spaces of the lungs. Injury to the lung may also cause pulmonary oedema through injury to the vasculature and parenchyma of the lung.
There are also a range of causes of pulmonary edema which are less well characterised and arguably represent specific instances of the broader classifications above. When circulatory causes have led to pulmonary edema, treatment with intravenous nitrates (glyceryl trinitrate), and loop diuretics, such as furosemide or bumetanide, is the mainstay of therapy. High altitude pulmonary edema — (HAPE) is a life threatening form of non cardiogenic pulmonary edema that occurs in otherwise healthy mountaineers at altitudes above 2,500 meters (8,200 feet). Flash pulmonary edema — In medicine, flash pulmonary edema (FPE), is rapid onset pulmonary edema. Basically this means there is an abnormal accumulation of fluid in the air sacs of your lungs that limits your breathing capacity.
Waking up at night with a feeling of breathlessness that you may be able to relieve when you sit up. The main cause of pulmonary edema has been attributed mainly to problems with your heart but it can happen any time your lungs become invaded with any type of infection.
Simply put, if your heart does not work right it is likely that you will develop pulmonary edema. This can result from electrocution or strangulation that will reduce the blood flow to your lungs and can lead to the build up of fluid. If you have been diagnosed with lung cancer the water retention can happen around and inside your lungs.
If you are going to be in high altitudes you need to make sure that you have the right equipment with you to help increase the air pressure and oxygen levels. If you have too much sodium in your body and the kidney’s cannot get rid of it all it can cause fluid retention. The main way that your physician can diagnosis pulmonary edema is by taking a chest x-ray because if there is any water retention around or in your lungs it can be seen on the x-ray.
The treatment that is use depends on what is causing the excessive fluid to accumulate in or around your lungs but for the treatment that is prescribed there are certain things that you must do. Taking a diuretic, either over-the-counter or prescription to help drain the excess fluid from your lungs.
Medications to treat the underlying cause such as antibiotics if you have tuberculosis, for congestive heart failure you may be given ACE inhibitors to help improve the circulation of your blood, high blood pressure medications to stabilize your blood pressure. To help boost the function of your heart you may be given Coenzyme Q10, a vitamin B1 supplement, vitamin E supplement. If you have severe edema you may have to use a breathing machine for a long period of time. It is very important to follow the medical advice and treatment that your physician gives you to get rid of the excessive fluid in and around your lungs so you get better and do not develop more serious health problems.
Cardiogenic acute pulmonary edema is an acute form of heart failure caused by increased pressure in the pulmonary capillary. In severe forms may be present hypercapnia and respiratory acidosis, which constitute signs of gravity. Its beneficial effects are explained by the occurrence of venous dilation, which will lead to decreased preload (quickly installed) and diuresis (which occurs in 20-90 minutes after the administration of furosemide).
Digoxin administration is contraindicated in cardiogenic acute pulmonary edema associated with mitral stenosis or with acute myocardial infarction.

Congestive heart, poor heart function, abnormal condition of the valves in heart or heart attacks lead to high accumulation of blood in the blood vessel of the lungs which in turn results to the fluid to be pushed out from the blood vessels to the alveoli. It is due to either failure of the left ventricle of the heart to adequately remove blood from the pulmonary circulation ("cardiogenic pulmonary edema"), see below, or an injury to the lung parenchyma or vasculature of the lung ("noncardiogenic pulmonary edema"), see below.[2] Whilst the range of causes are manifold the treatment options are limited, and to a large extent, the most effective therapies are used whatever the cause. In certain circumstances insertion of a Swan-Ganz catheter may be required to aid diagnosis. Liver enzymes, inflammatory markers (usually C-reactive protein) and a complete blood count as well as coagulation studies (PT, aPTT) are typically requested.
Classically it is cardiogenic (left ventricular) but fluid may also accumulate due to damage to the lung. The cause of pulmonary edema in the presence of a hypertensive crisis is probably due to a combination of increased pressures in the right ventricle and pulmonary circulation and also increased systemic vascular resistance and left ventricle contractility increasing the hydrostatic pressure within the pulmonary capillaries leading to extravasation of fluid and edema. The patient is given high-flow oxygen, noninvasive ventilation (either continuous positive airway pressure (CPAP) or variable positive airway pressure (VPAP)[12][13]) or mechanical ventilation and positive end-expiratory pressure (PEEP) in very severe cases. It is a medical condition that can not only be serious but it can also be life threatening. Some of the heart problems that can develop and cause pulmonary edema are defective heart valves, cardiomyopathy, congestive heart failure, high blood pressure, especially it if is uncontrolled or untreated, coronary artery disease, or having a history of heart attacks. In response to the infection the air sacs in your lungs become filled with fluid and pus, impairing the oxygen flow in your lungs. Some of the diseases that can cause this include cirrhosis, drinking alcohol in excess, and more. The physician may also suspect pulmonary edema if you have a lot of swelling in your legs and ankles and do a chest x-ray to confirm the diagnosis. Other causes that are responsible are lung infection, cocaine smoking, radiation and lung injury.
Treatment is focused on three aspects, firstly improving respiratory function, secondly, treating the underlying cause, and thirdly avoiding further damage to the lung.
The chronic development of pulmonary edema may be associated with symptoms and signs of "fluid overload", this is a non specific term to describe the manifestations of left ventricular failure on the rest of the body and includes peripheral edema (swelling of the legs, in general, of the "pitting" variety, wherein the skin is slow to return to normal when pressed upon), raised jugular venous pressure and hepatomegaly, where the liver is enlarged and may be tender or even pulsatile.
B-type natriuretic peptide (BNP) is available in many hospitals, sometimes even as a point-of-care test.
This damage may be direct injury or injury mediated by high pressures within the pulmonary circulation. The physician may also do an electrocardiography to gather information about your heart to see if that is the cause. In many cases kidney failure, brain surgery or bleeding in the brain may increase the fluid level in the blood vessels. Pulmonary edema, especially in the acute setting, can lead to respiratory failure, cardiac arrest due to hypoxia and death. When directly or indirectly caused by increased left ventricular pressure pulmonary edema may form when mean pulmonary pressure rises from the normal of 15 mmHg[3] to above 25 mmHg.[4] Broadly, the causes of pulmonary oedema can be divided into cardiogenic and non-cardiogenic. This is called hereditary angioedema, and it is not discussed in this article. Symptoms The main symptom is sudden swelling below the skin surface. You may also develop welts or swelling on the surface of your skin. The swelling usually occurs around the eyes and lips.
The swelling may form a line or be more spread out. The welts are painful and may be itchy.
