Appl. No.:

09/410198

Inventors:

Tae H. Joo - Redmond WA
David R. Hampton - Woodinville WA
James W. Taylor - Redmond WA
Ronald E. Stickney - Edmonds WA

Assignee:

Medtronic Physio-Control Manufacturing Corp. - Redmond WA

International Classification:

A61B 502

US Classification:

600528, 600483, 600509, 607 6

Abstract:

A method and apparatus determines the presence of a cardiac pulse in a patient by evaluating a physiological signal in the patient, preferably for the presence of characteristic heart sounds. The presence of a heart sound in a patient is determined by analyzing phonocardiogram (PCG) data obtained from the patient. Analyzing the PCG data may include evaluating temporal energy in the PCG data or evaluating spectral energy in the PCG data. Evaluating temporal energy in the PCG data may include estimating a first and second energy in the PCG data and comparing the first and second energy to determine a relative change in energy between them. Evaluating spectral energy in the PCG data may include calculating an energy spectrum of the PCG data and evaluating either the energy value or the frequency of a peak energy in the energy spectrum. The presence of a heart sound may also be determined by combining an evaluation of temporal energy with an evaluation of spectral energy in the PCG data. Electrocardiogram data obtained from the patient may further be used in connection with the PCG data to determine the presence of a cardiac pulse in the patient.

International Classification:

G06F 1760

US Classification:

705 3, 705 2

Abstract:

An event reporting program ( ) is provided which electronically records information critical to reconstructing events occurring during an emergency incident. The event reporting program ( ) includes an event recording component ( ) for recording events as they occur during the incident, and a post-processing component ( ) for further processing the events recorded by the event recording component after completion of the incident. The event recording component ( ) enables an emergency service provider to input a plurality of event records ( ) describing each event as it occurs and the time at which each event takes place. The event recording component also enables an emergency service provider to input a predefined protocol of expected event records. Each expected event record ( ) identifies an event which is expected to occur during the incident and a time at which the event is expect to occur. Finally, the event recording component also includes a number of tools for providing and/or recording information in addition to the event records to the emergency service provider, e. g.

International Classification:

A61B 500

US Classification:

600532, 73 233, 422 84

Abstract:

The invention presents techniques for identifying and guiding treatment for medical conditions, based upon the carbon dioxide concentration in the patients breath. In an exemplary application, the techniques of the invention may be used to distinguish obstructive lung disease from restrictive lung disease, even though the symptoms of the conditions are similar. The techniques of the invention may further be used to monitor the effectiveness of the treatment.

International Classification:

A61N 1/39
A61H 31/00

US Classification:

607 5, 601 41

Abstract:

Devices, methods, and software implementing those methods for providing communicating external chest compression (ECC) devices and defibrillation (DF) devices, where the ECC and DF devices can be physically separate from each other. Both ECC and DF devices are able to operate autonomously, yet able to communicate with and cooperate with another device when present. Some ECC and DF devices are adapted to be physically and/or electrically coupled to each other. One ECC device includes a backboard, a chest compression member, a communication module, controller, and at least one sensor, electrode lead or electrode. One DF device includes a defibrillator module, a controller, and a communication module that can communicate with the ECC communication module. The communicating ECC and DF devices may deliver ECC, pacing, defibrillation, ventilation, and cooling therapies, and may deliver instructions to human assistants, in a coordinated and cooperative fashion.

International Classification:

US Classification:

607 5, 607 59

Abstract:

An external defibrillator is customized for at least one person, i. e. , an anticipated patient, through creation of a profile for the anticipated patient that allows the defibrillator and users of the defibrillator to provide customized treatment to the patient. The profile may include treatment parameters for the anticipated patient, such as defibrillation therapy parameters selected for the patient. The profile may also include a baseline recording of a physiological parameter of the patient, and medical history and personal information regarding the patient. In some embodiments, the external defibrillator stores a profile for each of one or more anticipated patients within a memory. In other embodiments, a profile for an anticipated patient is stored within a medium associated with that anticipated patient. The medium may, for example, be a removable medium for external defibrillators.

International Classification:

A61N 1/39

US Classification:

607 6

Abstract:

The presence of a cardiac pulse in a patient is determined by evaluating physiological signals in the patient. In one embodiment, a medical device evaluates two or more different physiological signals, such as phonocardiogram (PCG) signals, electrocardiogram (ECG) signals, patient impedance signals, piezoelectric signals, and accelerometer signals for features indicative of the presence of a cardiac pulse. Using these features, the medical device determines whether a cardiac pulse is present in the patient. The medical device may also be configured to report whether the patient is in a VF, VT, asystole, or PEA condition, in addition to being in a pulseless condition, and prompt different therapies, such as chest compressions, rescue breathing, defibrillation, and PEA-specific electrotherapy, depending on the analysis of the physiological signals. Auto-capture of a cardiac pulse using pacing stimuli is further provided.

International Classification:

A61N 1/39

US Classification:

607 5

Abstract:

Methods and apparatus are provided for determining a defibrillation treatment protocol in an external defibrillator whereby a user may override a CPR-first default protocol. The method includes following steps configured in a defibrillator controller of issuing an inquiry; waiting for a response to the inquiry for a set time; ordering a CPR treatment protocol if no response is received within the set time; analyzing a response; ordering a CPR treatment protocol upon receiving a non-affirmative response to the inquiry; and ordering a shock treatment protocol upon receiving an affirmative response to the inquiry. Upon selecting a shock treatment protocol, the defibrillator performs a shock analysis under the shock treatment protocol, and either orders a CPR treatment protocol if shock treatment is not indicated by the shock analysis or provides a defibrillation shock if shock treatment is indicated by the shock analysis. Queries may be presented to a user in visual, audible, or both visual and audible format.
