Abstract

Mechanical ventilation (MV) is an important tool in ICU to deal with respiratory failure. Acute decompensated heart failure is a cause of admission to ICUs with respiratory failure. Pulmonary edema is a sign of respiratory failure among patients, increasing the need of MV. The diagnosis of HF is based on the presence of symptoms and signs, ECG, Natriuretic peptide level and assessment of EF by echocardiography. Diuretics are recommended to reduce the congestion, by achieving and maintaining euvolaemia with the lowest diuretic dose. ITP and volume changes during respiratory cycle affect the performance of the heart. Measurement of the TFC depends on the impedance cardiography phenomenon; which changes according to the resistance of thoracic contents to electric current. Lung congestion is a cause for weaning failure in cardiac patients. High TFC value could be an indirect measure of lung congestion and/or hypervolemia, which is a risk factor for failed weaning.
Aim:The aim of the work was to study the role of electrical cardiometry as a predictor of weaning from mechanical ventilation in cardiac patients with reduced ejection fraction.
