1. A system to increase survival with favorable neurological function after cardiac arrest, the system comprising:

  • a guidance device configured to provide feedback to a user to compress a patient'"'"'s chest at a rate of between about 90 and 110 compressions per minute and at a depth of between about 4.5 centimeters per compression to about 6 centimeters per compression;

    a pressure regulation system comprising a pressure-responsive valve that is adapted to be coupled to a patient'"'"'s airway, wherein the pressure-responsive valve is configured to remain closed during successive chest compressions in order to permit removal at least about 200 ml from the lungs in order to lower intracranial pressure to improve survival with favorable neurological function, and wherein the pressure-responsive valve is configured to remain closed until the negative pressure within the patient'"'"'s airway reaches about −

    7 cm H2O, at which time the pressure-responsive valve is configured to open to provide respiratory gases to flow to the lungs through the pressure-responsive valve.
