WebJan 31, 2024 · A recent critique of the PAC technique is that changes in waveform shape would also give rise to high PAC values—but would be associated with different physiological interpretations (Cole et al. 2024; Hwang et al. 2024). This argument suggests that waveform shape (i.e., change in shape of one signal–beta waveform) may be a better … WebPACath. Developed in 1993, the original version of the Pulmonary Artery Catheter Waveform Interpretation Tool (PACath) was a Windows-based computer program that provided expert knowledge in interpreting and troubleshooting pulmonary artery catheter (PAC) waveforms.
