Resuscitation and ventilation asynchrony monitor

Abstract

Resuscitation and ventilation monitoring devices are provided. A device includes an inlet in fluid communication with airflows exchanged with lungs of a patient and an airflow meter for measuring characteristics of the airflows. A user may provide a controller with patient information, e.g., height, weight, gender, or age, via a measurement selector, enabling the controller to determine acceptableranges of measured airflow characteristics. The device may determine a current mode of ventilation and associated ventilator settings based on the measured airflow characteristics. The device may also identify and filter out artifacts present in the ventilation signal, and determine whether a respiratory failure phenotype is present in the ventilation. If the current mode of ventilation and associated ventilator settings fall outside an acceptable range, the ventilation is classified as off-target and the controller may cause a sensory alarm to alert the user. The device may suggest a corrective action based on the type of off-target ventilation detected. The device may also continuously analyze ventilation to determine changes in lung compliance over time and to identify pathological changes over time. The device may work within a network of devices and user interfaces via wired or wireless communication, and is not restricted to or dependent on the type of ventilatory device with which a patient is being supported.

[0001] Statement of Government Interest [0002] This invention was made with Government support under Contract No. 5K12HL108964-05 awarded by the National Heart, Lung, and Blood Institute. The government has certain rights in this invention. [0003] Cross References to Related Applications [0004] This application claims the benefit of priority to U.S. Provisional Application No. 62 / 420,943, filed November 11, 2016, which is incorporated herein by reference in its entirety. technical field [0005] The present disclosure relates to patient resuscitation and ventilation monitoring systems. Background technique [0006] Acute respiratory failure is the most common cause of intensive care unit ("ICU") admission in the United States and is associated with an average in-hospital mortality of approximately 30% and attributable annual costs of $54 billion. Airway management is an important aspect of emergency resuscitation and emergency care. Providing appropriate ventila...

Problems solved by technology

Current studies have been limited by lack of access to ventilator data, invasive data collection methods that can introduce observer bias and limit the feasibility of continuous longitudinal data collection, limited clinical validation of algorithm performance, Impossibility to distinguish OTV subtypes, and lack of definitive analytical mechanisms to distinguish true OTV events from waveform artifacts that may lead to false positive event classification
