“…Using the wireless, wearable Doppler system developed by our group [6][7][8][9][10], we have observed that in resting, healthy volunteers, the common carotid artery max-to-centroid ratio falls between 1.5 and 1.7 over the entire cardiac cycle. Thus, for simplicity we assume that the VTI MAX-CA is 1.6 times the carotid artery centroid VTI (VTI CENT-CA ); that is, K = 1.6 and we express Eq.…”

A recent investigation by Cheong and colleagues should pique the interest of all clinicians who employ sonography during resuscitation [1]. In their report, a novel method of measuring the left common carotid artery, maximum velocity time integral (VTI MAX-CA ) was described and its value was related to the left ventricular outflow tract VTI (VTI LVOT ). Absolute VTI measurements (in centimeters) were made in critically-ill patients, though the population studied was relatively stable, seemingly not on vasoactive medications and with normal cardiac function. Importantly, there was no provocative (i.e., dynamic) maneuver carried out during their investigation.As anticipated, Cheong and colleagues observed a stronger relationship between total (i.e., systolic plus diastolic) VTI MAX-CA and VTI LVOT than between only the systolic portion of the VTI MAX-CA and the VTI LVOT . Of most interest, however, was the near parity between VTI MAX-CA and VTI LVOT in absolute value. Based on their regression equation, the VTI MAX-CA overestimated the VTI LVOT less than 10%. Considering why this might be so elaborates some caveats to their approach.

Precise and continuous monitoring of blood pressure and cardiac function is of great importance for early diagnosis and timely treatment of cardiovascular diseases. The common tests rely on on‐site diagnosis and bulky equipments, hindering early diagnosis. The emerging hydrogels have gained considerable attention in skin bioelectronics by virtue of the similarities to biological tissues and versatility in mechanical, electrical, and biofunctional engineering. However, hydrogels should overcome intrinsic issues such as poor mechanical strength, easy dehydration and freezing, weak adhesiveness and self‐recovery, severely limiting their precision and reliability in practical applications. Here, silk fibroin hydrogels are developed as resistive sensors for pulse waveform monitoring. The silk fibroin hydrogel is simultaneously transparent, extremely stretchable, extra tough, adhesive, printable, and environmentally endurable. The silk fibroin hydrogel is also conductive with high sensitivity, short self‐healing time, highly repeatable and reliable response, meeting the requirements for wearable sensors for continuous monitoring. The sensors with silk fibroin hydrogel present high‐quality and stable waveforms of radical and brachial pulses with high precision and rich features, providing physiological signals of blood pressure and cardiac function. The sensors are promising for personalized health management, daily monitoring and timely diagnosis.
