Systems and methods for monitoring patients with respiratory diseases are described. A system may include a sensor circuit to sense a respiration signal and at least one hemodynamic signal. The system may detect a specified respiratory phase from the respiration signal, and generate from the hemodynamic signal one or more signal metrics that are correlative to at least one of a systolic blood pressure, a blood volume, or a cardiac dimension. The system may detect a restrictive or obstructive respiratory condition when the hemodynamic signal metric indicates hemodynamic deterioration during a specified respiratory phase. The system may additionally classify the detected restrictive or obstructive respiratory condition into one of two or more categories, and deliver a therapy based on the detection or the classification.

A vital-data measurement controller is provided for controlling vital-data measurement when a user measures vital data by using a device data measurement. The measurement controller includes a controller that acquires image data including the user’s face and the device by controlling a camera; and an image processor that authenticates the user’s face and the based on the image data. The image processor then determines whether the device is worn by the user based on a positional relationship between the user and the device in the image data, and determines that a period in which the device is determined to be worn by the user after the authentication of the user and the device is a period of a proper state for measurement.

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.

A protective cover for a stethoscope comprises an elongate sleeve member having a closed first end and an open second end. The sleeve member defines an enclosed interior volume accessible via the open second end. A clip member is operatively connected to the first or second ear tube. A head and interconnecting elongate tubular body portion of the stethoscope are reposed in a position in the interior volume of the sleeve member such that the head and the body portion of the stethoscope are substantially covered. The clip member releasably holds the sleeve member in this position.

A breakaway stethoscope includes a chest piece, a headset, a tube, and a coupler. The chest piece captures sounds generated inside a person's body when the chest piece is positioned adjacent the person's body. The headset directs the sounds captured by the chest piece toward a person's ear when the headset is positioned on an ear of the person. The tube connects the chest piece to the headset and conveys the sounds captured by the chest piece toward the headset. The tube has a length and includes a first portion connected to the chest piece and a second portion connected to the headset. The coupler releasably connects the tube's first portion to the tube's second portion and releases one of the tube's portions when the tube experiences a force that urges at least one of the tube's portions to move away from the coupler.

A wearable electronic device according to an embodiment includes: a sensor module including a first sensor configured to sense a first signal including a pulse wave based on a respiration of a user corresponding to a first time, the respiration including an inhalation and an exhalation, and a second sensor configured to sense a second signal including a first pattern corresponding to the inhalation and a second pattern corresponding to the exhalation. The wearable electronic device includes a processor configured to: match a first respiratory characteristic of the first signal and a second respiratory characteristic of the second signal based on a correlation between the first signal and the second signal, and estimate a respiration phase of the user corresponding to the second signal measured at a second time after the first time, based on the matched first and second respiratory characteristics.

A system, method, scope device, and camera control module device for a video endoscopy system, to enable scopes to operate with a rolling shutter-type image sensor. With selected pulsing of a strobe light, subset image data from adjacent rolling-shutter frames is selected, gain compensated for missing light and combined into a new single video frame.

The invention includes a system and method for predicting the performance of production animals by analysis of heart and lung sounds to determine likelihoods the animals will develop BRD or other diseases or ailments. Vital signs of animals are recorded during an adrenergic sympathetic “flight or fight” situation. A cardio-pulmonary rate ratio is determined for each animal by dividing a normalized adjusted heart rate value by a normalized adjusted respiratory value. From the ratios calculated for each animal in a group, a ratio range is established. Ratio values at a lower end of the ratio range indicate higher relative respiration rates and poor lung performance due to disease. Ratio values at an upper end of the range may indicate low cardiac output and an inability to tolerate rapid weight gain. Ratio values at either end of the range may indicate compromised cardio-pulmonary function.
