Abstract: A transducer assembly comprising an inner, primary, transducer having a pair of transducers fixed to a liner or cavity for providing the fluid compression sending and receiving signals for measuring the velocity and change of composition of fluid in the cavity which is being inspired and expired by a patient in a setting, such as in an intensive care unit of a hospital. The inner transducer is disposed in a heated housing to maintain the temperature of the inner transducer at a temperature above the saturation point of the fluid being measured and is further provided with (1) an acoustical absorber to prevent sound energy from the connection tubes, which connect the transducer assembly to endotracheal tubing, from adversely affecting fluid measurements and, (2) water absorbing material to prevent I water, which might condense in the connecting tubing, from entering the inner transducer and affecting the fluid measurements.

Abstract: An impedance plethysmographic apparatus for monitoring respiration of a patient by measuring an impedance signal generated by changes occurring in the patient's chest has filter elements (30, 36) for removing cardiac artifact from the impedance signal caused by cardiac activity in the chest. The filter elements (30, 36) produces an output signal dependent only upon respiration activity in the patient's chest by removing any signals from said output caused by cardiac activity which is substantially periodic in character. There is also disclosed a method of removing cardiac artifact during monitoring of a patient's respiration using impedance plethysmography.

Abstract: A non-invasive system and procedure for deriving the blood gas content for a patient. The system measures the carbon dioxide concentration of the expiratory breath relative to volume. This data is then processed to derive arterial blood gas levels of carbon dioxide. If data sampling is in the time domain, the processing shifts the data from the time domain to the volume domain. The processing also iteratively assesses the significance of numerous variables. The resulting relationship provides a fast and accurate measure of blood gas content for both healthy and diseased lung patients.

Abstract: This invention is a spirometric device (100) for analyzing the strength of the exhalation of a patient. The device (100) is designed to sense and measure exhaled airflow rate, exhaled breath temperature, determine airflow volume, and record and display the respiratory movement of the patient for helping make medication recommendations. The device (100) includes an electronic package (336) mounted inside a housing (110) for computing and recording the strength, the temperature, and the volume of the exhalation along with the time and date. The device (100) includes a replaceable airflow chamber (130) mounted on the housing (110). A disposable mouthpiece (140) is releasably attached to the airflow chamber. A hot wire (430) is disposed inside the airflow chamber (130) and provides for measuring both airflow rate and temperature. An output of the hot wire (430) is connected to electronic circuitry (305) inside the housing for determining the proper volumes along with recording the time and date of the event.

Abstract: Single hand supportable and operable apparatus (30) for providing an output signal characteristic of the morphology of a respiratory tract includes an acoustic pipe (30) for exchanging acoustical energy with the tract. The pipe has an open first end (34) in communication with an opening in the respiratory tract. A transducer (38), such as a loudspeaker, is coupled to the pipe, producing an incident wave towards to opening in the tract and a reflected wave to form a transient wave filed in the pipe representative of the morphology of the tract. Preferably, first (40) and second pressure wave sensing transducers (42), such as microphones, mounted along the length of the pipe in spaced relationship provide first and second transduced signals representative of the transient wave field. A processor (66) processes the first and second transduced signals to provide an output signal characteristic of the morphology of the tract, such as the cross-sectional area as a function of the distance from the opening of the tract.

Abstract: A calorimeter for generating signals representative of the oxygen consumption and carbon dioxide production of a subject over a test period (12) includes two flow sensors (48, 64) and a carbon dioxide scrubber (66) connected to a patient mouthpiece (60). Interconnections (44, 46, 52, 54, 56, 58, 62) are such that the air inhaled by the subject passes through one flow meter and the exhaled breath passes first through the other flow meter, the carbon dioxide scrubber and then through the first flow meter. The electrical output signals from the flow meters are provided to a microprocessor based computer (50) which integrates the volume differences between the inhaled gas, and the exhaled gas after the carbon dioxide has been removed from it, over the period of the test.
