Monophasic, Biphasic & Triphasic Spectral Doppler Waveforms | Vascular Ultrasound Analysis (USG) *Cases Intro - 0:00 Monophasic - 0:10 Biphasic - 2:17 Triphasic - 4:28 Monophasic Waveform: Represents a single forward flow component throughout the cardiac cycle. The waveform has a rounded, blunted appearance and lacks the characteristic sharp peak. The waveform does not cross the baseline Biphasic Waveform: Consists of a forward flow during systole and a reversed flow component during early diast

This video shows the Doppler Effect when the source of a sound moves at 100 m/s toward a stationary observer. Later, the same source is seen moving away from the observer. Since the source of the sound is in motion relative to the observer, the observer will hear the sound with a different perceived frequency labeled f'. . The speed of sound is 343 m/s the frequency of sound is 343 Hz the wavelength λ of the sound wave is 343 m/s / 343 Hz = 1 m We will find the perceived frequency f' heard by th

Ever wonder how we monitor a turtle’s heart during surgery? 🐢💓 That whooshing sound you hear is from a Doppler flow detector - a handheld device that picks up blood flow using sound waves. It’s super helpful for monitoring our turtle’s heart rate and rhythm during surgery. Using a Doppler during turtle procedures is one of the best ways to keep an eye on how they’re doing under anesthesia. Simple, non-invasive, and crucial for a safe surgery. This Eastern Box Turtle was getting a deep debridem
