As a non-invasive method of haemodynamic monitoring, radiocardiography (RCG) correlates well with invasive methods. We have examined 25 patients during and after mechanical ventilation for the treatment of various types of respiratory insufficiency. The bedside mobile RCG set was used in the Intensive Care Clinic of our Institute. As a marker, indium was injected to the subclavian vein. The RCG recording was obtained using a scintillation camera, placed above the precordial area of the patient’s chest, and coupled to the ECG. For haemodynamic evaluation we measured blood volume, cardiac output, stroke volume, pulmonary transit time and pulmonary blood volume. The preliminary results of the studies performed are encouraging and in our opinion radiocardiography can serve as a non-invasive and useful tool. |
