This document describes a system for determining positioning of an intubation tube in a patient. The system can include a first acoustic sensor configured to be disposed to listen to one of a lung and a stomach of the patient and to provide a first signal. The system includes a signal processing unit, coupled to the first acoustic sensor, configured to analyze spectral components of the first signal and determine whether a frequency of the spectral components of the first signal are characteristic of sounds induced by ventilation via the intubation tube of airflow to the lung or the stomach of the patient.

Embodiments of the disclosure include systems and methods for reducing false positives in detection of pauses. For example, embodiments include a sensing component configured to obtain values of a first physiological parameter and determine a cardiac pause based on the values of the first physiological parameter. Furthermore, embodiments include performing a validation check of the determined cardiac pause using at least one of: the values of the first physiological parameter or values of a second physiological parameter.

A method and device for detecting phrenic nerve stimulation (PNS) in, or using, a cardiac medical device. A test signal sensitive to contraction of a diaphragm of a patient may be sensed and signal artifacts of the test signal within each of a first window of the test signal prior to a predetermined cardiac signal and a second window of the test signal subsequent to the predetermined cardiac signal may be determined. The PNS beat criteria may be evaluated, for example, using the test signal, which may be a heart sounds signal.

A medical implant includes an implant component configured to be implanted in a patient, an electrode array, an energy storage device, and a power management unit. The electrode array includes at least two electrodes spaced apart on the implant component. The energy storage device and power management unit are inside the implant component. The power management unit is operative to control electrical stimulation of the electrode array by current supplied by the energy storage device to be at a level which at least reduces formation of a biofilm on at least part of the implant component while implanted in the patient.

Provided are a biological sound measurement device capable of detecting contact with a body surface of a living body with a simple configuration, a control method for the biological sound measurement device, and a non-transitory recording medium storing a control program for the biological sound measurement device. The biological sound measurement device (1) includes: a measuring unit (3) that detects a biological sound of a living body in a state of contact with a body surface S of the living body; and a contact state determination unit (41) that determines whether or not a contact state is active in which the measuring unit (3) is in contact with the body surface S, based on a change in a sound pressure level of sounds detected by the measuring unit (3).

Described herein are systems and methods for assessing a condition of a mechanical circulatory support device (MCSD). The systems and methods can be used for early detection of device malfunction. The system can include a sensing subsystem that can obtain from one or more sensors signals indicative of at least one of vibrations or acoustics of the MCSD in operation in the mammal. The system can also include a computing subsystem. The computing subsystem can receive the signals indicative of at least one of the vibrations or the acoustics of the MCSD in operation in the mammal. process the signals to identify at least one harmonic in the signals, and evaluate the condition of the MCSD using the at least one harmonic identified in the signals indicative of at least one of the vibrations or the acoustics of the MCSD in operation in the mammal.
