Abstract: Systems and methods for a synchronized high-flow mode are disclosed. In examples, the synchronized high-flow mode varies the flow of breathing gases delivered to the patient to account of changes in a patient's peak inspiratory flow demand, improve the accuracy of measured partial pressure of CO2, maintain a more consistent distending pressure, reduce entrainment of room air, and enhance patient synchronization. In an example, a synchronized high-flow mode provides a baseline flow and increases the delivered flow above the baseline flow when the patient's demand exceeds a threshold. In this way, a synchronized high-flow mode may deliver a variable, or time-varying, flow based on the patient demand. Additionally, a minimum baseline flow may be selected and adjusted to maintain a minimum PEEP level.

Abstract: Training at the proper level of effort is important for athletes whose objective is to achieve the best results in the least time. In running, for example, pace is often monitored. However, pace alone does not reveal specific issues with regard to running form, efficiency, or technique, much less inform how training should be modified to improve performance or fitness. A sensing system and wearable sensor platform described herein provide real-time feedback to a user/wearer of his power expenditure during an activity. In one example, the system includes an inertial measurement unit (IMU) for acquiring multi-axis motion data at a first sampling rate, and an orientation sensor to acquire orientation data at a second sampling rate that is varied based on the multi-axis motion data.

Abstract: Systems and methods for non-invasively estimating intrapleural pressure and muscle pressure are disclosed. The disclosed estimation of intrapleural pressure functions in the presence of a leak and/or leak-compensated flow and does not require a maneuver. In examples, the muscle pressure is represented as a muscle pressure model with model parameters that are unique from breath to breath. An equation of motion relates the muscle pressure, respiratory mechanics, and measured ventilation data (e.g., airway pressure and flow). Based on past measured ventilation data, values for the respiratory mechanics and the model parameters are estimated. Constraints may be set on these values. An intrapleural pressure profile may be generated for past inhalation phases, based on the past measured ventilation data and the estimated model parameters and/or the estimated respiratory mechanics. The estimated respiratory mechanics may be used for real-time estimates of intrapleural pressure with real-time ventilation data.
