Can you tell what is wrong with this arterial line waveform? It is underdamped! An underdamped waveform causes an overestimate of systolic pressure and an underestimate of diastolic pressure. You’ll notice during your square wave test that the waveform produces several oscillations after the fast flash. The waveform may also appear more “whipped” and/or contain artifact waves. ➡️Causes: air bubbles in line, clot at the tip of the catheter, catheter positioned against the wall, tubing is too stif

29K views · 303 reactions | When a valve shuts, a pressure wave forms. We explore how this wave bounces within the system, inverting polarity at the plenum and valve, and its impact on harmonic frequencies. Our analysis focuses on the first harmonic. #ValveHarmonics #PressureWaves #FluidDynamics #Engineering #Physics #ValveOperation #Plenum #HarmonicFrequency #WaveBehavior #FluidMechanics | Bain Racing | Facebook

The video explains how cylinders use fluid pressure to convert pneumatic energy into mechanical force. It covers different types of cylinders: Single-acting cylinders have fluid pressure on one side of the piston for the forward stroke. Their symbol includes an open rectangle indicating external force is needed to retract the rod, with an open rod end exposed to atmosphere and a vertical line denoting the air port. Variants include: - **Spring-returned**: Air pressure drives forward motion, with
