Design outcomes

Primary

Measure	Time frame
Basic Measurement of Balloons Using several commercially available balloons of various sizes, measure the lateral diameter of the inflated balloons using calipers. Additionally, measure the air pressure of each balloon with an air pressure gauge to determine the optimal balloon size and degree of inflation for the load. Transthoracic Echocardiography Healthy adult volunteers will be included in the study. Two experienced physicians (one male and one female) specializing in echocardiography will use transthoracic echocardiography in the left lateral position in the Physiology Laboratory of the Central Laboratory of our institution. The hemodynamic effects of the party balloon maneuver were investigated using the protocol obtained from Experiment 1. This was compared to rest and the Valsalva maneuver (VM) using transthoracic echocardiography. Right ventricular inflow-velocity time integral (RV inflow-VTI) and left ventricular end-diastolic diameter (LVDd) were measured during and after the maneuver to assess changes in venous return. The various measurements were analyzed offline with images acquired after the examination.	—
