Respiratory Monitoring During Right Heart
Respiratory Monitoring During Right Heart
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.
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.
Inclusion Criteria:

 -  Patients undergoing right heart catheterization

 Exclusion Criteria:

 -  Inability or unwillingness to follow or to sign the study protocol.
