System for measuring respiratory function
InactiveUS7094206B2Easy to carryEasy to transportMedical automated diagnosisRespiratory organ evaluationBiological bodyAirway responsiveness
The present invention relates to a system for measuring respiratory function of living organisms. More particularly, signals indicative of the change in lung volume, defined as active and passive work, required to breathe and the airflow through the respiratory system of the living organism are obtained and processed as waveforms to provide a signal indicative of the respiratory restriction. The methods of the present invention measure clinical forms of airway obstruction, airway reactivity and lung volume and may be used to continuously or intermittently monitor patients with compromised respiratory function. In a preferred embodiment, a head-out, breath in respiratory plethysmograph system provides the signals indicative of change in lung volume as related to pressure changes in a chamber. Further, flowmetric variables are generated that provide a characterization of airway obstructions.

Systems and methods are provided to improve respiratory function. Systems include an external electrical stimulator coupled to electrodes that stimulates diaphragm contraction and may optionally include a positive pressure mechanical ventilator. The system further includes an electrode suitable for temporary implantation. Electrical stimulation is provided to specific portions of the diaphragm, such as one hemidiaphragm preferentially over another. By preferentially contracting one hemidiaphragm, a specific portion of a lung may be expanded, such as a posterior portion. By the provision of the negative intrathoracic pressure from diaphragm contraction, greater expansion of specific portion of lung is achieved in relationship to air pressure within the lung, thereby improving compliance. Supplementation of stimulated diaphragm contraction with positive pressure driven air flow from a PPMV directs the air flow to specific portions of the lung. Such portion may include a posterior portion of a lung, and may cause a clearing of atelectasis in that portion.

Method for using a non-invasive cardiac and respiratory monitoring system
InactiveUS20090048500A1Diagnostics using lightOrgan movement/changes detectionSonificationNon invasive
A non-invasive monitoring system using radiated energy to identify cardiac and respiratory waveforms in patients is discussed. The monitoring system illuminates a subject in radiated energy and then detects the reflected radiated energy caused by respiratory and / or cardiac functions. The detected reflections are used to plot a two-dimensional waveform. The waveforms represent the rise and fall of a detected signal (the reflected energy) over time and are indicative of the small movements of the patient's chest and abdomen that are associated with cardiac and respiratory function. Different implementations of the monitoring system use laser or ultrasonic energy to capture breathing and cardiac waveforms for analysis. The waveforms may be used to diagnose the effectiveness of prescribed sleep medication, perform remote line of sight monitoring from a remote location, identify crying waveforms for babies and infants, identify cardiac waveforms in a non-invasive manner and identify seizure and tremor activity.
