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

–DOPPLER ULTRASOUND–Sometimes, we need a device called a doppler (a mini ultrasound machine) to detect a pulse. A “doppler” might be used to detect a pulse in patients with:-Weak peripheral pulses-Pitting edema (cannot feel beneath the swelling)-Presence of a DVT or suspected DVT (think: blood flow may be entirely occluded!)-History of arterial blockage-Concern for current vessel occlusion-Pulses which are simply more difficult to feelTIPS for using:🫀Be sure to use these slowly, as they can cau
