RESCUE TEE Protocol for Cardiac Arrest Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for assessing cardiac arrest, such as transthoracic echocardiography, face limitations like poor acoustic windows and prolonged interruptions in cardiopulmonary resuscitation, which hinder effective treatment in emergency settings.
Innovation Solution
The RESCUE TEE Protocol employs a specific sequence of 12 transesophageal echocardiography views to rapidly identify the cause of cardiac arrest or shock, minimizing probe movement and providing continuous monitoring during CPR, allowing for immediate adjustments and targeted treatments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If transthoracic echocardiography (TTE) is used to assess cardiac arrest, then the procedure is conventional and easier to perform, but poor acoustic windows lead to misinterpretation of imaging and prolonged interruptions of CPR during pulse checks
Solution Approach 1:
The patent introduces the transesophageal echocardiography (TEE) probe as an intermediary device that bypasses the limitations of transthoracic imaging. By placing the ultrasound transducer directly in the esophagus adjacent to the heart, the probe eliminates the need for sound wave transmission through the chest wall, thereby avoiding poor acoustic windows while maintaining operational feasibility through standardized insertion and imaging protocols
2Ease of manufacture
If transthoracic echocardiography (TTE) is used to assess cardiac arrest, then the procedure is conventional, but prolonged interruptions of cardiopulmonary resuscitation (CPR) during pulse checks negatively affect cardiac arrest resuscitation
Solution Approach 1:
The patent implements continuous cardiac imaging through the TEE probe that remains in place during resuscitation efforts. The imaging can be performed without interrupting chest compressions or other CPR interventions, allowing for continuous assessment of cardiac function, detection of reversible causes, and monitoring of resuscitation effectiveness throughout the entire resuscitation process
3Speed
If transesophogeal echocardiography (TEE) is used in emergency cardiac arrest settings, then rapid assessment of cardiac status is enabled, but no standardized protocol exists for emergency procedures
Solution Approach 1:
The patent segments the comprehensive TEE examination into prioritized views based on emergency clinical needs. Rather than performing all standard TEE views, the protocol focuses on specific views (such as the four-chamber view, two-chamber view, and aortic valve view) that can be obtained in a systematic sequence to rapidly identify reversible causes of cardiac arrest, thereby reducing overall protocol complexity while maintaining diagnostic effectiveness

AI summary
A method is provided of treating cardiac arrest or shock in a patient without effective cardiac output and being administered chest compressions to maintain blood flow during cardiac arrest. The method employs transesophogeal echocardiography (TEE) used in a twelve-view examination of standard TEE views (RESCUE TEE) performed in sequence to minimize problem movement and provide a logical flow of views and information. The method allows for rapid monitoring of intra arrest pathology and adjusting chest compressions as necessary to optimize blood flow and initiating other treatments to stabilize the patient.
