  • Patent number: 12653976
    Abstract: A ventilation monitoring system for assisting in proper placement of an endotracheal tube in a subject includes: a capnography sensor configured to be placed in fluid communication with the endotracheal tube and to provide information representative of the subject's breath; and a processor in communication with the capnography sensor. The processor is configured to provide an indication of proper endotracheal tube placement when (1) a first indication of the subject's breath and a positive result of a first auscultation are identified within a first predetermined time period, and (2) a second indication of the subject's breath and a positive result of a second auscultation are identified within a second predetermined time period. The first auscultation includes auscultation of a subject's left lung, right lung, left axillary region, right axillary region, or abdomen. The second auscultation includes auscultation of another region of the subject different from the first auscultation.

The at least one processor is configured to implement a cardiopulmonary function analyzer to detect a suspected tachyarrhythmia based on an analysis of ECG signal(s) and verify the suspected tachyarrhythmia as a ventricular tachycardia (VT) event by analyzing acoustic signal(s) to distinguish the VT event from a supraventricular tachycardia (SVT) event. Said analysis includes determining an intensity and/or a beat-to-beat variability of a first heart sound (S1). The at least one processor verifies the suspected tachyarrhythmia as the VT event when the intensity of the S1 sound is below a predetermined intensity threshold or when the beat-to-beat variability of the S1 sound is above a predetermined variability threshold.
