Head up CPR device with integrated ventilator
A head up CPR system may include a base and an upper support coupled with the base and configured to elevate a patient's upper body. The system may include a chest compression device that is coupleable with one or both of the base and the upper support and a positive pressure ventilation system that is coupleable with the base.
1 . A head up CPR system, comprising:
a base;
an upper support coupled with the base and configured to elevate a patient's upper body;
a chest compression device that is couplable with one or both of the base and the upper support; and
a positive pressure ventilation system that is structurally mountable to the base, wherein:
the positive pressure ventilation system comprises a resuscitator bag and an automated resuscitator bag compressor; and
the resuscitator bag is removable from the automated resuscitator bag compressor for operation in a manual mode.
2 . The head up CPR system of claim 1 , wherein:
the positive pressure ventilation system comprises:
the manual resuscitator bag;
a mechanical linkage system; and
an actuator that drives the mechanical linkage system.
3 . The head up CPR system of claim 1 , further comprising:
an impedance threshold device that is configured to be interfaced with the positive pressure ventilation system.
4 . The head up CPR system of claim 1 , further comprising:
an automated external defibrillator.
5 . The head up CPR system of claim 1 , wherein:
the chest compression device is further configured to actively decompress an individual's chest between each compression.
6 . The head up CPR system of claim 1 , wherein:
the positive pressure ventilation system is configured to receive a signal that synchronizes delivery of a positive pressure ventilation with one or more phases of CPR compression/decompression cycles with one or both of continuous uninterrupted chest compressions and interrupted chest compressions.
7 . The head up CPR system of claim 6 , wherein:
the positive pressure ventilation system is controlled by one or both of an on/off switch and a signal that synchronizes delivery of a positive pressure ventilation with a phase of CPR.
8 . The head up CPR system of claim 6 , wherein:
the signal is received from one or both of a sensor and a controller.
9 . The head up CPR system of claim 1 , wherein:
the positive pressure ventilation system is configured to deliver positive pressure ventilations that have durations of between about 300 msec and 1200 msec.
10 . The head up CPR system of claim 1 , wherein:
the positive pressure ventilation system, the upper support, and the chest compression device are controlled by a same controller system.
11 . The head up CPR system of claim 1 , wherein:
the upper support is configured to elevate the patient's upper body from a starting position to an elevated position over a period of between about 30 seconds and 4 minutes.
12 . The head up CPR system of claim 1 , further comprising:
a controller that is configured to adjust one or more of a ventilation rate, a tidal volume, and a compression:ventilation ratio.
13 . The head up CPR system of claim 1 , wherein:
the positive pressure ventilation system is configured to receive a selection for one or more parameters selected from the group consisting of a positive pressure ventilation delivery rate, a tidal volume, and a duration of positive pressure ventilation delivery.
14 . The head up CPR system of claim 1 , further comprising:
a carrying case comprising one or more compartments that are configured to hold the base and the upper support, the chest compression device, and the positive pressure ventilation system.
15 . A method of increasing the probability of survival with good brain function in a sudden cardiac arrest patient, comprising:
positioning a patient on a head up CPR system such that a chest compression device of the head up CPR system is aligned with the patient's heart;
elevating a portion of the patient's upper body;
performing chest compressions and active chest decompression on the patient using a chest compression device of the head up CPR system while the portion of the patient's upper body is elevated; and
delivering positive pressure ventilations using a positive pressure ventilation device of the head up CPR system, wherein:
the positive pressure ventilation device is structurally mounted to a base of the head up CPR system;
the positive pressure ventilation system comprises a resuscitator bag and an automated resuscitator bag compressor; and
the resuscitator bag is removable from the automated resuscitator bag compressor for operation in a manual mode.
16 . The method of increasing the probability of survival with good brain function in a sudden cardiac arrest patient of claim 15 , wherein:
delivery of the positive pressure ventilations is synchronized with a phase of CPR.
17 . The method of increasing the probability of survival with good brain function in a sudden cardiac arrest patient of claim 15 , further comprising:
regulating an intrathoracic pressure of the patient while the portion of the patient's upper body is elevated.
18 . The method of increasing the probability of survival with good brain function in a sudden cardiac arrest patient of claim 15 , wherein:
elevating a portion of the patient's upper body comprises elevating the patient's head from a first height of between about 8-10 cm to a second height of between about 15-25 cm.
19 . The method of increasing the probability of survival with good brain function in a sudden cardiac arrest patient of claim 15 , wherein:
a chest compression rate is slowed from around 90-120 compressions/min to 50-80 compressions per minute to allow for more time during the decompression phase when a positive pressure breath is delivered and synchronized with the decompression phase of the CPR cycle.
