Underdamping/Overdamping of Arterial Pressure Waveforms
Nov 29, 2002 · During direct intra-arterial measurement of blood pressure (A) the mean arterial pressure will be unaffected by small air bubbles in the system (B) an underdamped system will overestimate the mean arterial pressure (C) an underdamped system will overestimate the diastolic pressure (D) long tubing from the catheter to the transducer will tend to decrease …
re: a-line waveform interpretation | Student Doctor Network
Nov 5, 2006 · It's my understanding that fluctuations in an a-line waveform due to mechanical ventilation can be used to guesstimate hemodynamic response to a fluid challenge. Would this also be the case in a spontanously-breathing, non-intubated patient? I heard from a fellow that it also does but I...
