Time cost of ineffective IV fluids in the emergency department
Journal of Intensive Care
In a sample of 53 ED patients, a clinically significant amount of time was spent providing physiologically ineffective IV fluids. Identifying fluid unresponsive patients earlier in their care pathway may represent an avenue to improve ED care efficiency.

Wearable ultrasound and provocative hemodynamics: a view of the future
Critical Care
Miniature doppler ultrasound devices can provide simultaneous ultrasound of arterial and venous blood flow to infer both cardiac input and output, to help clinicians decide whether patients are fluid non-responsive. Such devices have the potential to generate the slope of the patient’s cardiac function curve in real-time and facilitate a paradigm shift toward personalized therapy in the ICU.

Wearable carotid Doppler tracks changes in stroke volume induced by end-inspiratory and end-expiratory occlusion
Health Science Reports
Changes in stroke volume patterns induced in end-inspiratory end-expiratory occlusion tests were found to be reflected in both the common carotid and the aorta. VTI variability of the Doppler device was less than that of traditional duplex Doppler.

FloPatch Doppler detects mild-to-moderate central hypovolemia
Journal of Trauma and Acute Care Surgery
FloPatch wearable Doppler ultrasound continuously measured the common carotid artery Doppler pulse. Carotid Doppler measures were highly sensitive at detecting both 10% and 20% stroke volume reduction and all shock indices performed well in their diagnostic ability to measure mild-to-moderate central volume loss.
