Respiratory Monitoring During Right Heart

Study Overview
=================
Brief Summary
-----------------
Respiratory monitoring during right heart catheterization to differentiate between various types of pulmonary hypertension; The effects of the cardiovascular system on the lung mechanical properties.

Detailed Description
-----------------
Differentiation between different kinds of pulmonary hypertension (PHTN) requires right heart catheterization. Monitoring heart failure patients is challenging in many. The study will enroll patients undergoing right heart catheterization (RHC) for the evaluation of heart failure and PHTN, based on the regular clinical practice. The regular indices as the right ventricle pressure (RVP), pulmonary artery pressure (PAP), pulmonary artery wedge pressure (PAWP), and cardiac output will be measured with the Swan Ganz Catheter and recorded. Noninvasive measurement of the respiratory flow will be acquired by a medical approved flow-meter that is mounted on a simple plastic breathing mask. Non-invasive system that includes three accelerometers that are attached to the chest and epigastrium of the patient will be used to measure respiratory chest wall dynamics. Through evaluating the correlation between the invasive and non-invasive measurements the study intends to prove the ability of the non-invasive system to provide the required information.
