Abstract
A reciprocal cardiac compressor is provided for cyclically compressing a patient's chest. The cardiac compressor includes a resuscitator for ventilating the patient's lungs. A first internal electrode is positioned in the esophagus of the patient with an esophageal-pharyngeal airway. The resuscitator ventilates the patient's lungs through the esophageal-pharyngeal airway. The cardiac compressor includes a compressor pad positioned anterior to the patient's heart for compressing the patient's sternum and heart. An external electrode is disposed on the face of the compressor pad for compression between the compressor pad and the patient's sternum. A cardiac defibrillator is connected between external and internal electrodes for establishing a defibrillating electric current therebetween. A monitor is connected to the external and internal electrodes for monitoring the electrical activity of the patient's heart. Means for synchronizing the defibrillator and the compressor is provided comprising a pressure sensitive switch for synchronizing the defibrillator and compressor such that defibrillating current is applied to the patient's heart only during a systolic portion of the compression cycle of the compressor.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
