摘要:
A device for performing chest compressions for CPR in coordination with applying electro-stimulus for additional resuscitative actions such as electro-ventilation, electro-counterpulsion, and defibrillation. The device includes a chest compression mechanism, electrodes and power supply for electro-stimulus, and a control system for applying electro-stimulus in coordination with the action of the chest compression mechanism.
摘要:
A method of processing a raw acceleration signal, measured by an accelerometer-based compression monitor, to produce an accurate and precise estimated actual depth of chest compressions. The raw acceleration signal is filtered during integration and then a moving average of past starting points estimates the actual current starting point. An estimated actual peak of the compression is then determined in a similar fashion. The estimated actual starting point is subtracted from the estimated actual peak to calculate the estimated actual depth of chest compressions. In addition, one or more reference sensors (such as an ECG noise sensor) may be used to help establish the starting points of compressions. The reference sensors may be used, either alone or in combination with other signal processing techniques, to enhance the accuracy and precision of the estimated actual depth of compressions.
摘要:
Improved procedures for cardiopulmonary resuscitation of a victim of cardiac arrest are provided. In the resuscitation the victim chest is mechanical compressed and decompressed to stimulate the heart. The victim is induced to inspire and expire against insufflating breathing gas during the chest compression/decompressions. The breathing gases are adduced under pressure to promote the development of a positive coronary perfusion pressure. Electro-stimulation of the heart can be carried after positive coronary perfusion pressures have been achieved. The electro-stimulation can be defibrillation or heart pacing or both. The chest compression/decompression cycles and the electro-stimulation measures are synchronized to promote sufficiently body circulation of oxygenated blood in a subject suffering from cardiac arrest. Medical equipment systems are provided for implementing the CPR procedures.
