Carefully time pressure events with the ecg. right heart catheterization cheat sheet: interpretation of pressures and waveforms direct measurements central venous interpretation pressure ( cvp) right- sided intracardiac pressures ( ra, right heart catheterization interpretation pdf rv) pulmonary arterial pressure ( pap) pulmonary capillary wedge pressure ( pcwp) cardiac output ( co) mixed venous oxyhemoglobin saturation ( svo2) indirect measurem. confirm the scale of right heart catheterization interpretation pdf the recording. it is the gold standard method for diagnosing pulmonary hypertension ( ph) and an essential component in the evaluation of patients prior to heart and/ or lung transplantation. review the tracings for common artifacts. 2 3 rhc can be also used to assess the haemodynamic effects of treatments directly and provides an entry route pdf for intracardiac biopsy. establish the zero level and balance transducer. this is the only test that directly measures the pressure and blood flow inside your heart and the blood vessels of your lungs. right heart catheterization ( rhc) represents the gold standard for measuring pulmonary haemodynamics. critically assess the pressure waveforms for proper fidelity.
a right heart catheterization pdf ( right heart cath or rhc) is considered the gold standard test for a definitive diagnosis of pulmonary hypertension ( ph). he then advanced it into the right atrium and administered drugs directly into the right heart chambers. in 1929 a surgical resident named werner forssmann in germany performed the first right heart catheterization on a human by inserting a 65 cm urethral catheter on himself through his left antecubital vein. rhc is mandatory to confirm the diagnosis of pulmonary hypertension ( ph), to assess the severity of haemodynamic impairment and to perform vasoreactivity testing in selected patients. collect hemodynamics in a systematic method using established protocols. - 40 mmhg for rhc, 200 mmhg for lhc.
