Pulmonary Artery Pressure (PAP) Measurement

Pulmonary Artery Pressure (PAP) measurements -- mean PAP, systolic PAP and diastolic PAP -- visually mark the waveform output, which is influenced by a number of factors that can lead to measurement errors. The Mikro-Cath Pressure Catheter delivers a more accurate and reproducible PAP waveform, independent of the factors that impact fluid-filled readings, simplifying both the recording and reading of PAP derived parameters.

What is Pulmonary Artery Pressure?

Pulmonary Artery Pressure (PAP) is one of the most commonly measured parameters during a cardiac catheterization case.

How is Pulmonary Artery Pressure Measured?

Mean PAP, systolic PAP and diastolic PAP are often derived by visually marking the waveform output by a fluid-filled transducer. This waveform is influenced by a number of factors, including patient position, transducer level, air bubbles, open connections and catheter tubing length, all of which can introduce error into the measurement. The result is a potential for over-estimation or under-estimation of the systolic and diastolic values.

The Millar Mikro-Cath diagnostic pressure catheter can be introduced into the pulmonary artery via a 6F or larger multi-purpose catheter to deliver a more accurate and reproducible PAP waveform, independent of the factors which impact fluid-filled readings. The result is a simplification in both the recording and reading of PAP derived parameters.
