Problems solved by technology

A known limitation of this measurement method is that excessive noise is present in the TTI signal due to a number of noise sources, including body motion during chest compressions, capacitive fluctuations, and electrolyte charge transfer
However, TTI-based ventilation measurements alone do not provide an accurate measure of tidal volume unless an initial calibration procedure is performed, which is inconvenient due to the normal random anatomical fluctuations in the patient

Embodiment Construction

[0040] There are many possible embodiments of the invention, which cannot be described here. Some preferred possible embodiments are described below. However, it cannot be overemphasized that these are descriptions of embodiments of the invention, not of the invention, and therefore the invention is not limited to the specific embodiments described in this section, but rather as defined in the claims. described in broad terms.

[0041] The terms "caregiver", "rescuer" and "user" are used interchangeably to denote a facility operator who provides care to a patient.

[0042] Referring to FIGS. 1 and 2 , an automatic external defibrillator (AED) 10 includes a removable cover 12 and a device housing 14 . Defibrillator 10 is shown in FIG. 2 with cover 12 removed. Electrode assembly 16 (or a pair of separate electrodes) is connected to device housing 14 by cable 18 . The electrode assembly 16 is stored under the cover 12 when the defibrillator is not in use.

Abstract

A device for assisting a caregiver in delivering cardiac resuscitation to a patient, the device comprising a user interface configured to deliver prompts to a caregiver to assist the caregiver in delivering cardiac resuscitation to a patient; at least one sensor configured to detect the caregiver's progress in delivering the cardiac resuscitation, wherein the sensor is configured to provide a signal containing information indicative of ventilation; a memory in which a plurality of different prompts are stored, including at least one ventilation progress prompt to guide the rescuer's performance of ventilation; a processor configured to process the output of the sensor to determine a parameter descriptive of ventilation progress and to determine whether the ventilation progress prompt should be selected for delivery. Possible parameters descriptive of ventilation progress include ventilation rate, delivered tidal volume, and flow rate.

Description

technical field [0001] The present invention relates to devices (such as automatic external defibrillators) for assisting a caregiver in administering cardiac resuscitation therapy to a patient. Background technique [0002] Resuscitation for a victim of cardiac arrest typically involves clearing and opening the patient's airway, giving artificial respiration, and performing chest compressions to direct blood flow to the patient's heart, brain and other vital organs. If the patient has a shockable rhythm, resuscitation may also include defibrillation therapy. The term "basic life support (BLS)" refers to all of the following: initial assessment; airway maintenance; expiratory ventilation (rescue respiration); and chest compressions. When all of these treatments are combined, the term "cardiopulmonary resuscitation (CPR)" is used. [0003] There are many different kinds of abnormal heart rhythms, some of which can be managed with defibrillation therapy ("shockable rhythm") ...
