Abstract: A sleep study system comprises a set of sensors for monitoring physiological parameters of a subject during sleep as part of a sleep study and for monitoring the sleep stage of the subject. It is determined if intervention to the subject is needed for maintenance or repair to the sleep study system. If so, a time to perform the intervention is also derived based on the sleep stage of the subject, in particular so as to be least disruptive to the subject.

Abstract: A respiratory effort sensing apparatus (2) includes a flexible belt member (8) having a first buckle member (12A) and a second buckle member (12B), and a wearable respiratory monitoring recording device (6). The monitoring device includes: (i) a processing apparatus (34) structured to be selectively operable in a sleep mode and an active mode, and (ii) buckle detection circuitry (46) structured to detect that both buckle members are operatively coupled to the respiratory monitoring recording device and in response thereto generate a buckle detection signal. The processing apparatus is structured to, in response to receiving the buckle detection signal, automatically: (a) move from the sleep mode to the active mode, and (b) generate data indicative of a respiratory effort of a patient over time based on an effort-based signal generated by the respiratory effort sensing apparatus in response to changes in volume of a body part of the patient.

Abstract: An apparatus for use in diagnosing the presence of obstructive sleep apnea (OSA) in a patient includes a sensing module structured to measure a parameter indicative of a tremor in the patient's neck, tongue and/or throat muscles while the patient is awake, the parameter not being airflow through the patient's airway. The sensing module generates one or more electrical signals based on the measured parameter. The apparatus also includes a processor operatively coupled to the sensing module, the processor being structured to receive the one or more electrical signals, perform an analysis of the one or more electrical signals, and based on the analysis determine whether the tremor has a frequency in at least one predetermined frequency range that is indicative of OSA.

Abstract: Described herein is a nasal cannula apparatus. The apparatus is configured to detect the pressurized flow of breathable gas to and/or from the airway of a subject through the nose of the subject. The apparatus comprises a body, a first nasal cannula system formed in the body configured to engage a first nostril of a first nasal passage, and a second nasal cannula system formed in the body configured to engage a second nostril of a second nasal passage of the subject. The second nasal cannula system is joined to first nasal cannula system by a bridge such that the first nasal cannula system engages the first nostril and second nasal cannula system engages the second nostril at the same time. The apparatus is configured to transmit expiratory and inspiratory nasal pressurized flow to connective conduits.

Abstract: The present disclosure pertains to a nasal cannula apparatus (10). The apparatus is configured to detect the pressurized flow of breathable gas to and/or from the airway of a subject through the nose of the subject. In some embodiments, the apparatus comprises a body (17), a first nasal cannula system (12) formed in the body configured to engage a first nostril of a first nasal passage, and a second nasal cannula system (34) formed in the body configured to engage a second nostril of a second nasal passage of the subject. The second nasal cannula system is joined to first nasal cannula system by a bridge (38) such that the first nasal cannula system engages the first nostril and second nasal cannula system engages the second nostril at the same time. In some embodiments, the apparatus is configured to transmit expiratory and inspiratory nasal pressurized flow to connective conduits (20, 40).
