A cough event is differentiated from a sneeze event of a test subject enclosed within a plethysmograph test chamber by measuring air pressure changes during the event, and comparing the pressure changes against criteria indicative of a cough to determine the likelihood that the event is a cough. Air pressure changes are recorded as pressure and / or sound values. A graphical record of a waveform of changes in the air pressure during an event relative to a baseline value is recorded, and a value is calculated that is indicative of the likelihood that the event is a cough based on the sizes of areas between the waveform and baseline during the event, said areas including a first area indicative of the change in air pressure during air inspiration, a second area indicative of the change in air pressure during air compression, and a third area indicative of the change in air pressure during expiration.

Method and system of determining nibp target inflation pressure using an sp02 plethysmograph signal
InactiveUS20080045846A1Improve performanceCatheterDiagnostic recording/measuringUltrasound attenuationBlood pressure cuffs
A method and system for operating a non-invasive blood pressure monitor that utilizes an SpO2 plethysmograph signal to determine the initial inflation pressure for the blood pressure cuff of the NIBP monitor. A pulse sensor is placed on the patient's limb distal to the blood pressure cuff such that as the blood pressure cuff is inflated, the pulse signals from the pulse sensor will be reduced. When the blood pressure cuff reaches systolic pressure, the pulse signals from the pulse sensor will be initially attenuated and eventually eliminated, thus providing an indication that the cuff pressure has reached systolic pressure for the patient. The central processor of the NIBP monitor compares the pulse signals during cuff inflation to an average pulse signal and terminates the inflation of the blood pressure cuff upon sufficient attenuation. The use of the SpO2 plethysmograph signal to determine the initial inflation pressure reduces both the over-inflation of the blood pressure cuff and the under-inflation of the blood pressure cuff which increases the rate at which the blood pressure measurement can be made while increasing patient comfort.

A method and system for operating a non-invasive blood pressure monitor that utilizes an SpO2 plethysmographic signal to reduce the time required to obtain an estimation of a patient's blood pressure. During operation of the NIBP monitor, the NIBP monitor utilizes the SpO2 plethysmographic signal to determine a timing period and a deflation period for each pulse associated with the patient's heartbeat. Upon receiving an oscillation pulse, the NIBP monitor determines the oscillation amplitude during the timing period and deflates the blood pressure cuff during the deflation period immediately following the timing period. Preferably, the deflation period occurs during the same oscillation pulse used to calculate the oscillation pulse amplitude to decrease the amount of time required to obtain a blood pressure estimate from the patient.

Non invasive measurement of infant lung function during unsedated sleep is achieved by a plethysmograph which comprises of a rigid acrylic box (10) with integral water sealed spirometer (11) and a vacuum-actuated neck seal (20) allowing "head out" monitoring. The neck seal comprises particulate material entrapped in the space between two layers of rubber, which become rigid when a vacuum is applied to the space. Tidal volume, respiratory rate and changes in functional residual capacity (FRC) are able to be recorded during unsedated REM and NREM sleep whilst monitoring with conventional polysomnographic methods. The head out configuration allows additional instrumentation to be used, avoids facial stimulation and allows unimpeded access to the upper airway.

Reusable inductive transducer for measuring respiration
InactiveUS20060258948A1Improve electrical performanceLow costRespiratory organ evaluationSensorsElectrical conductorSignal-to-noise ratio
The present invention is an inductance plethysmograph transducer particularly suited for use in respiratory monitoring. The transducer is in the form of a woven fabric providing a substantially flat extensible belt for encircling a portion of a patient for a wide range of patient sizes. The transducer is used for monitoring changes in cross-sectional area corresponding to changes in volume of an expandable organ such as the patient's chest or abdomen. At least one electrical conductor is woven directly into the fabric in a manner that improves the electrical performance of the transducer over the prior art in two ways. First, a high-density weave is used for the fabric that produces many more inductive turns of the embedded conductor(s), thereby increasing the overall inductance change, hence improving the signal to noise ratio, and increasing the expandability of the effective length of the transducer. Secondly, the conductor(s) are oriented within the weave perpendicular to the surface or the torso of a patient being monitored, thus reducing artifact due to body capacitance. In addition to improvements in the electrical performance, the manufacture of the inductance sensor is a single step process that can be carried out on existing looms, reducing the overall cost while improving the flexibility, durability, and ease of use. The present invention is also machine washable making reuse much less labor intensive and therefor much less expensive.
