Problems solved by technology

This loss of tone manifests itself in a significant increase in the compliance of the vasculature on the body, which, like an increase in capacitance in an electrical circuit, leads to an increase in the intrinsic time constant of the system

Embodiment Construction

[0023] There are quite a few possible embodiments of the invention, too numerous to describe here. Some possible embodiments that are presently preferred are described below. It cannot be emphasized too strongly, however, that these are descriptions of embodiments of the invention, not a description of the invention, which is not limited to the embodiments described in detail in this section but which is described in more general terms in the claims .

[0024] Figure 1 shows a block diagram of one embodiment. Microprocessor 14 controls ventilator function 15, chest compressor 12, drug infusor 14, and defibrillator / pacer 13 in an integrated manner. Physiological sensors2 such as accelerometer-based sternal movement detection3 methods of sternal movement detection, and filtering and processing of these various signals such as end-tidal carbon dioxide detection (EtCO 2 ) signal processing9 and pulse oximetry (SpO 2 ) is used to judge the physiological and physical state of th...

Abstract

Apparatus for automatic delivery of chest compressions and ventilation to a patient, the apparatus including: a chest compressing device (12) configured to deliver compression phases during which pressure is applied to compress the chest and decompression phases during which approximately zero pressure is applied to the chest; a ventilator (15) configured to deliver positive, negative, or approximately zero pressure to the airway; control circuitry and processor (14), wherein the circuitry and processor are configured to cause the chest compressing device to repeatedly deliver a set containing a plurality of first type flow cycles, each first type flow cycle comprising a first type decompression phase and a first type compression phase, and at least one second type flow cycle interspersed between sets of first type flow cycles, each second type flow cycle comprising a second type decompression phase and a second type compression phase, wherein the second type decompression phase is substantially longer than the first type decompression phase.

Description

technical field [0001] This invention relates to cardiac resuscitation devices, and more particularly to devices for the automatic control of chest compressions and ventilations. Background technique [0002] Resuscitative treatment of patients with cardiac arrest usually includes cleaning and opening the patient's airway (airway), providing artificial respiration to the patient with a manually operated bag-valve or electric portable ventilation equipment, and applying chest compressions to the victim. Provides blood flow to the patient's heart, brain and other vital organs. Chest compressions may be delivered by manually compressing the patient's chest in the sternal region or by using a powered chest compressor. Resuscitation may also include defibrillation therapy if the patient has a shockable heart rhythm. The term basic life support (BLS) includes all of the following elements: initial assessment; air circuit maintenance; ventilation with exhaled gases (rescue respir...
