Abstract
Mechanical ventilation is one of the most important tools used in ICU to deal with respiratory failure and pulmonary edema. Its role is significant in critically ill studied cases particularly in cardiac studied cases with systolic dysfunction & reduced EF. Weaning from mechanical ventilation is a challenge and needs a good understanding of heart-lung interaction to reach a successful outcome.
Acute decompensated heart failure has been one of the most frequent causes of admission to intensive care units with complaints of respiratory failure. Pulmonary edema (PO) is one of the major signs of respiratory failure at the time of admission among these studied cases increasing need for mechanical ventilation.
A structural or functional heart defect that results in elevated intracardiac pressures & insufficient cardiac output, whether at rest or throughout exercise, is known as heart failure. Heart failure has been a constellation of symptoms & indicators. Heart failure with decreased EF is described as having EF of less than forty percent or having severe LV systolic dysfunction along with HF symptoms & indications.
Diagnosis of HF has been based on the existence of symptoms & signs, electrical cardiography (ECG), Natriuretic peptide level, and assessment of EF by echocardiography.
To lessen signs & symptoms of congestion in studied cases with HFrEF, loop diuretics are advised. Euvolaemia maintenance with the least amount of diuretic is the goal of diuretic therapy. intravascular space’s fluid volume is reduced by diuretic medication, permitting mobilization of edoema from extravascular space.
Heart & lung occupy the same intrathoracic space, & this mechanical arrangement has been comparable to a pump inside of another pump. ITP & volume fluctuations throughout the respiratory cycle consequently have an impact on the heart’s functionality.
