Abstract: Systems and methods are presented for monitoring brain pulsatility. A change in volume of the brain is estimated based at least in part on an output of a non-contact, surface measuring sensor (e.g., a distance sensor or a camera). A metric indicative of brain pulsatility is then calculated based at least in part on a ratio of the estimated change in volume of the brain relative to a change in arterial blood pressure.

Abstract: A monitoring apparatus includes a clip assembly configured to be secured on a patient's digit. The clip assembly houses an accelerometer which measures acceleration in three dimensions. A microcontroller is configured to receive acceleration data from the accelerometer representative of the acceleration measured in each of the three dimensions. A processor is configured to analyze the acceleration data and determine and output a train-of-four ratio based the acceleration measured in each of the three dimensions.

Abstract: An extendable Intubation stylet including a handle member and a trigger mechanism moveable relative to the handle member between a retracted position and an extended position. A hollow semi-rigid stylet member extends from the handle member from a proximal end to a distal end. A flexible stylet member has a proximal end and a distal end and extends through the semi-rigid stylet member with the proximal end of the flexible stylet member connected with the trigger mechanism and configured such that when the trigger mechanism is in the retracted position, the flexible stylet member distal end is proximate the semi-rigid stylet member distal end and when the trigger mechanism is in the extended position, the flexible stylet member distal end is extended from the semi-rigid stylet member distal end.

Abstract: A method and apparatus for qualitative sensory signal, capnography-guided intubation is provided. A qualitative sensory signal, such as an audible signal, is generated during intubation of a patient to provide an audible indication of carbon dioxide levels, so as to facilitate proper placement of an intubation tube. The frequency of the audible signal corresponds to measured carbon dioxide levels, thereby providing a simple, easy-to-interpret, audible indication of the current position of an endotracheal tube during intubation, as well as confirmation of proper placement of the tube. Alternatively, the qualitative sensor signal may be an omni-directional visual signal or a palpable vibratory signal.

Abstract: A modified esophageal Doppler monitor with two ultrasonic Doppler transducers that is capable of measuring time rate change of pressure within the aorta and aortic pulse wave velocity is provided. Methods of using this modified monitor to assess aortic compliance, diagnose atherosclerotic disease and assess efficacy of therapeutic agents for atherosclerotic disease are also provided.
