The catheter with the inflated balloon is advanced further, until the PA waveform disappears, and a venous-looking waveform appears. This is the wedge waveform. It indicates that the pulmonary artery is occluded. The pressure here should also be 6-12 mmHg, like the PA diastolic pressure.

"WebOct 2, 2024 · I-V waveforms and PA classes of operation. In PA design, “class” is a term used to describe the design approach for the amplifier. This mainly consists of the bias condition and operating mode of the transistor as the output signal is driven to its intended power level. Three of the most basic classes are Class A , Class AB and Class B. " - Flat pa waveform
