Adaptive CPR Positioning for Cerebral Perfusion During Chest Compressions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing CPR methods often fail to effectively maintain optimal blood circulation and cerebral perfusion due to the limitations of chest compressions performed in a supine position, which can lead to increased intracranial pressure and reduced cerebral perfusion gradient.
Innovation Solution
A system comprising a patient support structure that adjusts the patient's body position during CPR, allowing for chest compressions to be administered at an angle, utilizing a chest compressor, tilt adjusters, and sensors to optimize tilt angles for improved coronary and cerebral perfusion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If chest compressions are administered in a supine position, then the administration is simple and straightforward, but blood circulation and cerebral perfusion are not effectively maintained
Solution Approach 1:
The patient support structure transitions from a static supine position to a dynamic adjustable position, allowing the backrest to be tilted to a predetermined angle (e.g., 30-45 degrees) to optimize blood circulation and cerebral perfusion during CPR while maintaining ease of operation through automated or semi-automated positioning mechanisms
Solution Approach 2:
The system changes the positional parameter of the patient's body from horizontal (0 degrees) to an inclined position (30-45 degrees) by adjusting the backrest angle, thereby improving hemodynamic parameters such as cerebral perfusion pressure and coronary blood flow while preserving operational simplicity through integrated control systems
2Device complexity
If chest compressions are administered in a supine position, then the setup is simple, but intracranial pressure increases and cerebral perfusion gradient decreases
Solution Approach 1:
The support structure incorporates a dynamic tilt adjustment mechanism that elevates the patient's upper body to a predetermined angle during CPR, reducing intracranial pressure and improving the cerebral perfusion gradient while maintaining setup simplicity through automated positioning and integrated control systems
Solution Approach 2:
The system preemptively adjusts the patient's body position to an inclined posture before or during the onset of harmful effects (increased intracranial pressure), thereby preventing the deterioration of cerebral perfusion gradient while keeping the overall system setup relatively simple through integrated positioning mechanisms

AI summary
An automated chest compression (CC) system is described that includes a chest compressor configured to administer chest compressions to a patient, at least one tilt adjuster configured to tilt at least the head of the patient to a tilt angle during the administration of chest compressions to the patient, a patient support structure configured to couple to the chest compressor and to the at least one tilt adjuster, one or more tilt sensors, and a CC device controller configured to control the chest compressor to administer the chest compressions at a resuscitative rate, receive one or more signals, from the one or more tilt sensors, indicative of the tilt angle, determine tilt angle information from the one or more signals indicative of the tilt angle, and provide the tilt angle information to a user interface, wherein the patient support structure is adapted to support the back of the patient.
