Flash Pulmonary Edema or Crash Pulmonary Edema is a clinical characterization of acute heart failure with a dramatic presentation. [4] It is an acute cardiac disease precipitated by cardiac events and usually associated with severe hypertension.
Edema of the lungs should be thought of as the result of a disease such as congestive heart failure and not a disease in and of itself. In this case it would be a cardiac disease and not a pulmonary disease. Cardiogenic pulmonary edema is typically caused by either volume overload or impaired left ventricular function.
It may also occur in the abdominal cavity, where the fluid buildup is called ascites. In left-sided heart failure edema can occur in the lungs – this is called cardiogenic pulmonary edema. This reduces spare capacity for ventilation, causes stiffening of the lungs and reduces the efficiency of gas exchange by increasing the distance between ...
Heart failure (HF), also known as congestive heart failure (CHF), is a syndrome caused by an impairment in the heart's ability to fill with and pump blood. Although symptoms vary based on which side of the heart is affected, HF typically presents with shortness of breath , excessive fatigue , and bilateral leg swelling . [ 3 ]
The pathophysiology of pulmonary heart disease (cor pulmonale) has always indicated that an increase in right ventricular afterload causes RV failure (pulmonary vasoconstriction, anatomic disruption/pulmonary vascular bed and increased blood viscosity are usually involved [1]), however most of the time, the right ventricle adjusts to an ...
There is a circulatory overload which may lead to pulmonary edema secondary to an elevated diastolic pressure in the left ventricle. These individuals usually have a normal systolic function but symptoms are those of heart failure. With time, this overload causes systolic failure. Ultimately cardiac output can be reduced to very low levels. [1]
NPPE develops as a result of significant negative pressure generated in the chest cavity by inspiration against an upper airway obstruction. These negative pressures in the chest lead to increase venous supply to the right side of the heart while simultaneously creating more resistance for the left side of the heart to supply blood to the rest of the body (). [4]
Ultimately the ventricle walls need to be the right size relative to the size of the chamber in order for the heart to work effectively. Any major deviation from that can lead to heart failure. Alright, even though systolic failure is most common in left-sided heart failure, diastolic heart failure or filling dysfunction can also happen.
