The Square Wave test is used to help with the interpretation of values for arterial lines. This test is nothing more than a fast flush that exposes the transducer to high pressure creating a square waveform. This high pressure creates vibrations in the transducer, then it is followed by a damping coefficient, or how fast the vibrations stop.
5: The atrial waveform | Thoracic Key
https://thoracickey.com/5-the-atrial-waveform/
The atrial waveform is composed of the positive atrial (A) and ventricular (V) waves and the X and Y descents. The A wave is prominent with abnormalities of RV and LV compliance (e.g., hypertrophy, ischemia). The V wave is accentuated in cases of atrioventricular valve regurgitation (RA V wave in TR, LA V wave in MR).

Arterial waveform in hypertension and peripheral vascular disease. The waveform depicted here represents the arterial pressure wave of a hypertensive person with poorly compliant arteries, borrowed from Mills et al (2008), who in turn adapted it from Smith et al (2000). It is supposed to be an aortic pulse waveform produced by applanation tonometry of …
Arterial waveform: Peripheral vs. Central
https://www.openanesthesia.org/arterial_waveform_peripheral_vs-_central/
Arterial waveform: Peripheral vs. Central As the arterial pressure wave travels from the central aorta to the periphery, the arterial upstroke becomes steeper, the systolic peak becomes higher, the dicrotic notch appears later, the diastolic wave becomes more prominent, and end-diastolic pressure becomes lower.

The shape of the peripheral arterial pressure waveform may indeed contain information useful to the anesthesiologist and intensivist. The maximal slope of the peripheral arterial pressure tracing seems to be related to left ventricular contractility, although the relationship may be confounded by other hemodynamic variables.

The arterial waveform will show a notch on the downward stroke; this notch is called the dicrotic notch and is due to the closure of the aortic valve. The remainder of the downward stroke is the diastolic flow of blood into the arterial tree. A patient with abnormal heart rhythm or valvular abnormalities will have an abnormal arterial waveform.

Information derived from the arterial pressure waveform. Historically, the arterial line waveform has appeared in the exam in several forms. The trainees have at one stage been expected to discuss broadly what sort of information can be derived from it ( Question 30.2 from the second paper of 2013 and Question 11.2 from the first paper of 2021). In the Part One, …

Proper monitoring of arterial waveforms requires positioning, calibration, and zeroing of the transducer system in order to prevent false elevations in blood pressure measurement or artificial dampening of the waveform. ... Once this is done, the pressure tracing should rest on the zero line of the monitor and a pressure value of zero should be ...

Analysis of the atrial pressure tracing begins with identification of the P wave in the ECG. The first positive-pressure wave to follow the P wave is the a wave. The right atrial a wave usually is seen at the beginning of the QRS complex, provided that atrioventricular conduction is normal .
