Ventilator Timing Control and Mask Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current CPR methods face challenges due to the difficulty in determining the optimal timing of chest compressions relative to artificial respirations, leading to prolonged non-compression, non-respiration periods and potential incorrect administration, especially in emergency situations where trained personnel may not be available.
Innovation Solution
A ventilator system that automatically adjusts air/oxygen delivery based on mask size, providing pre-selected pressure, breath volume, and respiratory rate, and includes a signaling mechanism to guide rescuers on the timing of chest compressions, minimizing non-compression, non-respiration time during CPR.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual CPR administration is performed without automated timing control, then flexibility in operation is maintained, but timing precision between compressions and respirations deteriorates
Solution Approach 1:
The system performs self-detection of mask presence and self-adjustment of ventilation parameters based on mask size, eliminating the need for manual configuration and reducing timing errors while maintaining operational simplicity
Solution Approach 2:
The system continuously monitors respiratory parameters and provides real-time feedback to synchronize chest compressions with the respiratory cycle, ensuring precise timing control without requiring complex manual coordination
2Manufacturing precision
If automated mask detection is implemented, then administration accuracy is improved, but device complexity increases
Solution Approach 1:
The system replaces complex mechanical mask-size adjustment mechanisms with electronic sensors that automatically detect mask presence and size, achieving high administration accuracy through simple electronic detection rather than complex mechanical systems
Solution Approach 2:
The system uses optical or electrical sensors to create an electronic copy/detection of the mask's physical characteristics, allowing automatic parameter adjustment without requiring physical measurement or manual intervention
3Productivity
If prolonged non-compression non-respiration periods occur, then complete respiratory cycles are achieved, but oxygen delivery efficiency deteriorates
Solution Approach 1:
The system dynamically adjusts respiratory parameters and timing based on real-time detection of mask size and patient characteristics, optimizing the balance between complete respiratory cycles and continuous oxygen delivery to eliminate prolonged idle periods
Solution Approach 2:
The system maintains continuous useful action by synchronizing chest compressions with the respiratory cycle and minimizing non-compression non-respiration periods, ensuring that oxygen delivery and blood circulation efforts are continuously effective without unnecessary interruptions

AI summary
A ventilator system and method can deliver artificial respirations to a person receiving cardiopulmonary resuscitation. The system and method may provide intermittent breath delivery (e.g., with interruptions), so that activation of the device gives a specific predetermined number of breaths, interspersed with a set time period of no breath. This pattern may be by default, manually triggered where one activation gives a set number of breaths followed by a pause until the next activation for breath (one activation gives one breath cycle), or one activation results in continuous cycle of intermittent breaths). In some embodiments, a signaling mechanism may deliver signals to a rescuer relating to timing of chest compressions of the person. The timing of the chest compressions for the signals may be based on a time of delivery of the artificial respirations. In certain embodiments, different sized masks each include a gas flow restrictor which is unique for the size of mask. The ventilator system may assess the size of the mask based on a pressure differential created by the unique gas flow restrictor.
