Ventilatory methods and devices to enhance the efficacy of cardiopulmonary resuscitation

The system, devices, and method described herein may improve the outcomes of cardiac arrest patients being treated with CPR. The improvement is the result of enhancing intrathoracic pressure both during the chest compressions or constrictions as well as the relaxations. The enhancement is achieved by synchronizing low-volume inflations of the lungs with each chest compression and low-volume deflations with each chest relations. The high rate and fidelity of these ventilations are achieved by a unique multichannel endotracheal tube that uses high press oxygen and vacuum at its distal tip to administer and remove low-volume ventilations at the high rates of CPR compressions and relaxations. The synchronized oscillations of the airway pressure are transmitted physiologically to the intrathoracic space and augment forward blood flow. The system, devices, and method incorporate measurement of airway pressure and biomarker feedback control loops so as to avoid over pressurization or over depressurization of the lungs.
