The present invention describes a method and apparatus for detecting and quantifying intrinsic positive end-expiratory pressure (PEEPi) of a respiratory patient breathing with the assistance of a ventilator. A processing device receives respiratory airway data from one or more sensors adapted to non-invasively monitor a respiratory patient, calculates from the respiratory airway data two or more parameters that are indicative of or quantify intrinsic positive end-expiratory pressure of the patient, and generates an indication intrinsic positive end-expiratory pressure (PEEPi).

Method and apparatus for detecting and quantifying intrinsic positive end-expiratory pressure

The present invention describes a method and apparatus for detecting and quantifying intrinsic positive end-expiratory pressure (PEEPi) of a respiratory patient breathing with the assistance of a ventilator. A processing device receives respiratory airway data from one or more sensors adapted to non-invasively monitor a respiratory patient, calculates from the respiratory airway data two or more parameters that are indicative of or quantify intrinsic positive end-expiratory pressure of the patient, and generates a predicted quantitative value for intrinsic positive end-expiratory pressure based on the two or more parameters. The respiratory airway data is transformed into a predicted quantitative value for intrinsic positive end-expiratory pressure (PEEPi).

A system for collecting an exhaled breath sample and exhaled breath aerosol from a subject includes a condensation chamber having an outerwall defining an interior space. The outer wall has an inlet port and an outlet port therethrough in fluid communication with the interior space. The inlet port is placeable in fluid communication with an exhaled breath sample of the subject. A condensation element is positioned within the condensation chamber interior space and has a shape tapering downwardly toward a bottom tip thereof. A condensation of fluid on the condensation element is enhanced through various elements. A collection area is positioned within the condensation chamber's interior space beneath the condensation element bottom tip. The collection area is for collecting condensate accumulating on an outer surface of the condensation element and dropping from the tip thereof.

Breath and breath condensate analysis system and associated methods

A system for monitoring medication compliance in a patient includes an electronic pill that includes a drug-transporting device and an antenna positioned on a surface of the drug-transporting device. A detector is positionable external a gastrointestinal tract of a patient for detecting a presence of the antenna in the patient gastrointestinal tract.

Medication compliance system and associated methods

The present invention describes a method and apparatus for non-invasive prediction of the 'intrinsic positive end-expiratory pressure' (PEEPi) which is secondary to a trapping of gas, over and above that which is normal in the lungs; the presence of PEEPi imposes an additional workload upon the spontaneously breathing patient. Several indicators or markers are presented to detect and quantify PEEPnon-invasively The markers may include an expiratory air flow versus expiratory air volume trajectory, an expiratory carbon dioxide flow versus expiratory air volume trajectory, an expiratory carbon dioxide volume to expiratory air volume ratio, an expiratory air flow at onset of inhalation, a model of an expiratory waveform, a peak to mid-exhalation airflow ratio, duration of reduced exhaled airflow, and a Capnograph waveform shape.
