Dr. Michard shows in this presentation Multiple noninvasive techniques are currently available on the horizon , measuring fluid responsiveness, cardiac output and tissue perfusion. An interesting technique in the operating room is the use of arecruitment maneuver and assessment of stroke volume or cardiac output [noninvasively] applying the 3×30 rule to predict fluid responsiveness.
Techniques with micro-sensors, both for S VO2 and carotid blood flow are also available already. A wearable collar as real-time detects change in chest impedance, could be very valuable in anticipating increased extravascular lung water/pulmonary edema.
In cardiology similar techniques were already available, but by means of invasive techniques through the MIMS pulmonary artery monitor or measurement of thoracic impedance, OptiVol, available on many new or implantable defibrillators and CRT- P devices.
I posted the video on YouTube to the web this morning as an easy reference.
I apologize, I forgot to turn of my microphone and created a painful "echo" but the video is still audible ( i hope)
