TRINITRINE
patients presenting to the emergency department with acute onset dyspnea are assessed for acute heart failure using the bio impedance technology (BIOPAC system) to measure the cardiac output in different clinical situations. FIRST: the cardiac output (CO) is measured at the reference position. Inbetween each step the patient was put in the reference position during 5 minutes.
0.6 mg of nitroglycerin was given to the patient sublingual and we measure the cardiac output by BIOPAC system(0.6 mg of Nitroglycerin was administered sublingually and CO was evaluated.
