Definitions

  • BACKGROUND Defibrillators and defibrillator-external pacemakers are employed to restore and maintain a heart's normal rhythm in either an emergency situation such as cardiac arrest, or voluntarily to normalize a person's rhythm in non-life threatening situations (e.g., atrial fibrillation).
  • Use of a defibrillator requires specific certification resulting from such programs as the American Heart Association's Advanced Life or Base Life Support courses. Further institutional or organizational training or competency evaluation may also be required. These requirements generally remain true for both manual and semi-automatic (AED) defibrillators. In order to maximize familiarity with this lifesaving equipment, institutions and organizations generally require periodic recertification and or demonstration of competency.
  • FIG. 6 gives an example of a prior art visual prompt for communicating a user error.
  • a recognized shortcoming of visual prompts is that they can be easily overlooked under the stress of an emergency situation. They are passive as this approach relies on an operator looking specifically at the display field at all times. Newer AED defibrillators have taken the step of incorporating graphic prompts or icons into the physical design and labeling of the product in order to give them more permanency.
  • defibrillators have incorporated a variety of high and low pitched tones as alert alarms to draw attention to the device, initially successful, their shortcoming has become a lack of specificity.
  • the growing trend toward incorporating more vital sign parameters into pre-hospital defibrillators also raises the number of warning tones rescuers must decipher.
  • voice prompts have been employed to simplify the therapeutic use of defibrillators.
  • defibrillators have begun to expand the range of the voice prompting to include the ABCs
  • Snyder U.S. Patent No. 6,356,785 expand the use of therapeutic voice prompts to include BLS and ALS treatment protocols; operational faults are communicated to the operator by visual indicators (e.g., LED) or non-specific tonal sounds.
  • Stendahl U.S. Patent No. 5,955,956 describes the use of an audible alarm system in an AED in response to processor detected faults that are found during a periodic self-test. Borgenicht U.S.
  • Patent No. 6,405,082 describes the use of tonal and verbal prompts to confirm the therapeutic modes of a defibrillator, i.e., to alert the operator that the defibrillation mode has been selected, or that one is charging for synchronized cardioversion.
  • the invention features a medical caregiving device (e.g., a defibrillator) that incorporates corrective voice prompts that navigate users around operator errors.
  • the voice prompts may, for example, address errors of readiness (e.g., failing to connect the defibrillator to an AC power source, failing to pre-connect electrodes, etc.), errors of omission (i.e., forgetting to do something, such as attempting to deliver a shock before the defibrillator is charged), and errors of commission (i.e., doing the wrong thing, such as attempting to shock VF when in the synchronization mode).
  • the voice prompts may address errors in the delivery of therapy (e.g., attempting to shock VF when in the synchronization mode) or they may address errors other than in the delivery of therapy (e.g., failing to connect to an AC power source).
  • the invention features a medical device of the type used for assisting a user in delivering therapy to a patient, the device comprising a user interface including a speaker configured to deliver voice prompts to a user to assist the user in operating the device; at least one sensor or circuit element configured to detect an error made by the user in operating the device; a memory in which a plurality of different voice prompts are stored; a processor configured to determine which of the different voice prompts should be selected for delivery based on the detected error; and circuitry configured to work with the memory and the user interface and speaker to deliver the selected voice prompt.
  • the device may include a defibrillator.
  • the selected voice prompts may address errors in the delivery of therapy, or they may address errors other than errors in the delivery of therapy.
  • the voice prompts may include a prompt to correct the user's error in failing to select the defibrillation mode.
  • the voice prompts may include a prompt to correct the user's error in selecting synchronized delivery of electrical stimulation during a cardiac arrest situation.
  • the voice prompts may include a prompt to correct the user's error in failing to charge the defibrillator's battery.
  • the voice prompts may include a prompt to correct the operator's failure to connect the device to AC power.
  • the voice prompts may include a prompt to correct operator errors associated with the storage, management, deletion, transmission, or correction of information.
  • the voice prompts may include a prompt to correct operator errors associated with the use of removable forms of media.
  • the voice prompts may include a prompt to correct operator errors associated with the use of wired or wireless transmission of data.
  • the voice prompts may include a prompt to correct operator errors associated with recording, displaying, storing, or printing of electrocardiographic (ECG) data.
  • ECG electrocardiographic
  • the voice prompts may include a prompt to correct operator errors related to analysis of electrocardiographic (ECG) data.
  • the voice prompts may include a prompt to correct operator errors associated with vital signs monitoring.
  • the vital signs monitoring may comprise one or more of the following: heart rate, temperature, blood pressure (non-invasive and invasive), pulse oximetry, end tidal CO2, respiration, blood gases, CO, or blood chemistries.
  • the voice prompts may include a prompt relating to errors in calibration, sensor replacement, environmental issues (i.e. high ambient lighting), or cable placement.
  • the voice prompts may include a prompt to correct operator errors associated with transcutaneous pacing.
  • the voice prompts may include a prompt relating to increasing or decreasing pacing rate.
  • FIG. 1 is a block diagram illustrating one implementation of the invention.
  • FIG. 2 is a block diagram illustrating a second implementation of the invention.
  • FIG. 3 is a block diagram illustrating a third implementation of the invention.
  • FIG. 4 is a perspective view of an automatic external defibrillator (AED) of a type that could incorporate one or more implementations of the invention.
  • FIG. 5 is a block diagram of at least a portion of an AED implementation.
  • FIG. 6 is a view of a prior art defibrillator display showing a visual prompt for communicating an error to a user.
  • FIG. 7 is a table listing examples of non-therapy-delivery errors for which voice prompts could be delivered
  • FIG. 8 is a table listing examples of therapy-delivery errors for which voice prompts could be delivered.
  • FIG. 1 depicts one possible manner in which voice prompts may be used to correct operator errors of a type that could generally be called errors of omission.
  • the operator presses (12) the button designated for shock delivery.
  • the microprocessor controlled logic initially detects (14) whether the defibrillator is in the defibrillator mode (e.g., it may be in the pacing mode).
  • a voice prompt is delivered (16) to the operator to "Select the Defibrillator Mode.”
  • the defibrillator mode may have already been selected, but the operator may have failed to charge the defibrillator. If this is detected (18), the defibrillator may prompt (20) the operator to "Press the Charge Button.” The same approach may be applied to the pacing mode, to cardioversion, and to other applications.
  • FIG. 2 depicts another implementation, in which voice prompts are used to correct operator errors of a type that could generally be called errors of commission.
  • the defibrillator prompts the operator (22) regarding a user-created problem that blocks the delivery of therapy.
  • the depicted logic and resulting voice prompt will guide the operator around the self-generated problem. If the logic has determined that the synchronization mode has been selected, it then determines (24) whether there are R waves present. If so, then it may prompt (26) the operator to remove the synchronization selection.
  • FIG. 3 depicts the concept of a "sentinel" that continuously monitors critical defibrillator functions and operations; this implementation could be regarded as assisting in correction of readiness errors. In this implementation, the logic monitors (28) the comiection to an AC power source.
  • FIG. 4 shows the exterior of an automatic external defibrillator 10 of a type that might incorporate the voice prompts disclosed herein.
  • FIG. 5 shows some of the basic functional blocks that would be implemented in an external defibrillator (e.g., an AED) that incorporated the implementations disclosed herein.

Abstract

Il est prévu un dispositif médical tel qu’un défibrillateur comportant des messages vocaux correctifs aidant les utilisateurs à se diriger parmi les erreurs de guidage. Les messages vocaux peuvent par exemple porter sur des erreurs de préparation (par exemple un oubli de connexion du défibrillateur à une source d’alimentation alternative, de connexion préliminaire d’électrodes, etc.), des erreurs d’omission (c’est-à-dire oublier de faire quelque chose, comme une tentative d’administration d’un choc avant le chargement du défibrillateur) et des erreurs de commission (c’est-à-dire faire ce qu’il ne faut pas, comme une tentative de choc VF en mode de synchronisation). Les messages vocaux peuvent porter sur des erreurs lors de l’administration de la thérapie (par exemple une tentative de choc VF en mode de synchronisation) ou bien ils peuvent porter sur des erreurs autres que l’administration de la thérapie (par exemple un oubli de connexion à une source d’alimentation alternative).
