The presence and origin of apnea in a newborn subject is detected by separately and concurrently monitoring relative movement of the cranial bones and nasal ventilation. The cranial bones have been found to move with respiration as a function of intrapleural pressure, and monitoring of their movement is accordingly used to generate a signal representative of intrapleural pressure. A nasal cannula, thermistor, thermocouple or CO. sub. 2 sensors are employed to concurrently generate a signal representative of tidal volume. Absence of changes in both cranial bone movement and respiratory air flow at the nose is indicative of the presence of central apnea, while absence of nasal air flow accompanied by continuing cranial bone movements is indicative of obstructive apnea. The preferred device for detecting cranial bone movement is a surface inductive plethysmographic transducer, although other suitably sensitive motion detecting devices may be employed.

An apparatus and method for distinguishing between different types of apneic episodes. The method includes measuring a new index, TCD/VT, and measuring the phase relation between the abdominal and rib cage contributions to total respiration volume. The episode is classified as central, obstructive or mixed based on the value of TCD/VT and the phase relation.

The present invention is an apparatus and method for improving the detection of the inductance "signal" generated by an inductive plethysmograph (12). Signal detection is improved by modifying the design of the inductive plethysmograph (12) and also by improving the design of the associated circuitry. By virtue of these improvements, the associated circuitry may be located remotely rather than on the transducer, as is the current practice. In one aspect of the invention, the impedance matching transformer (14) joining the inductive plethysmograph (12) to the oscillator (16) is selected such that the inductance of its primary winding is greater than about ten times the reflected inductance of the inductive plethysmograph (12) and the cable (24) joining it to the transformer (14). In accordance with another aspect of the invention, the inductive plethysmograph (12) is modified such that the conductor (20) incorporated therein encircles the relevant body portion a plurality of times. In yet a further aspect of the invention, the cable (24) connecting the inductive plethysmograph (12) to the transformer (14) is selected such that the ratio of the diameter of its screen to the diameter of its center conductor is minimized for reducing the inductance per unit length thereof.

The present invention relates to the field of ambulatory and non-invasive monitoring of a plurality of physiological parameters of a monitored individual. The invention includes a physiological monitoring apparatus with an improved monitoring apparel worn by a monitored individual, the apparel having attached sensors for monitoring parameters reflecting pulmonary function, or parameters reflecting cardiac function, or parameters reflecting the function of other organ systems, and the apparel being designed and tailored to be comfortable during the individual's normal daily activities. The apparel is preferably also suitable for athletic activities. The sensors preferably include one or more ECG leads and one of more inductive plethysmographic sensor with conductive loops positioned closely to the individual to preferably monitor at least basic cardiac parameters, basic pulmonary parameters, or both. The monitoring apparatus also includes a unit for receiving data from the sensors, and for storing the data in a computer-readable medium. The invention also includes systems comprising a central data repository for receiving, storing, and processing data generated by a plurality of physiological monitored apparatus, and for making stored data available to the individual and to health care providers.

A subject rebreathes an inert aerosol from a closed system and, during each of a plurality of breaths, the aerosol concentration in the closed system is determined and compared to determine differences with a predetermined concentration value. Identified differences indicating enhanced aerosol deposition signify airway narrowing and/or an increase in accumulated airway secretions.

A method and system for extracting cardiac parameters from a plethysmographic signal is described wherein the plethysmographic signal is passed through a first filter to remove non-cardiac components of the signal. A second filter averages a plurality of cardiac cycles and cardiac parameters are extracted from the averaged cardiac signal.

A method for monitoring cardiopulmonary events is disclosed. The basic method comprises looping an extensible conductor (14) in close encircling relation about the neck (12) of the subject (10), providing a signal indicative of the inductance of the loop, and monitoring the signal. This signal contains both qualitative and quantitative cardiopulmonary information. In accordance with another aspect of the method, an extensible conductive loop (14) is disposed in close encircling relation about the head such that the plane defined by the loop extends through the mouth. By providing a signal indicative of changes in the inductance of the loop, qualitative and quantitative information for mouth volume may be obtained.

A non-invasive physiologic signs monitoring device includes a garment with electrocardiogram electrodes and various inductive plethysmographic sensors sewn, embroidered, embedded, or otherwise attached to the garment with an adhesive. The garment is in the form of a shirt. When the garment is fitted over the torso of the patient to be monitored, the electrodes and sensors generate signals in response to the physiologic signs of the patient. The signals are transmitted to a recording/alarm device where they are monitored for adverse conditions and logged. When an adverse condition or other preprogrammed condition occurs, a message is communicated to the patient by either an audio message or a display. The recording/alarm unit is also connectable to a remote receiving unit for monitoring by a health care professional or other machine.

A non-invasive method and apparatus for monitoring individual lung function is disclosed. A transducer (12, 14) is disposed on the torso above the lung to be monitored, the transducer producing a signal corresponding to movement of the torso portion therebeneath which, in turn, corresponds to changes in the volume of the underlying lung. Regional lung volume changes may also be assessed by utilizing transducers positioned on the torso to encompass only a portion of the underlying lung.
