1Reliability

If mandatory minute ventilation mode is used to guarantee smooth transition from controlled ventilation to spontaneous respiration, then patient safety is improved, but lack of effective visualization and monitoring tools leads to potential inefficiencies

Engineering Contradiction:
Improvepatient safetyVSAvoidventilation state information
Core Design Contradiction:
ReliabilityVSLoss of information

Solution Approach 1:

The system implements feedback by continuously monitoring respiratory parameters (spontaneous ventilation volume, machine ventilation volume, respiratory rate) and providing real-time visual feedback through graphs that display current values against target values. This allows clinicians to see the effect of ventilation settings adjustments and make informed decisions to optimize patient respiratory support during the transition from controlled to spontaneous respiration.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The visual graph interface acts as an intermediary between the complex ventilation parameters and the clinician. It translates multiple numerical parameters into an intuitive visual representation showing ventilation state, target control parameters, and associated control parameters, making it easier to monitor and adjust ventilation strategies without being overwhelmed by raw data.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If multiple ventilation parameters are monitored to optimize respiratory support, then ventilation effectiveness is improved, but complexity of monitoring and adjustment increases

Engineering Contradiction:
Improveventilation optimization efficiencyVSAvoidmonitoring system complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system merges multiple ventilation parameters (spontaneous ventilation volume, machine ventilation volume, respiratory rate, ventilation state) into a single integrated visual graph interface. This consolidation allows clinicians to monitor all critical parameters simultaneously in one view, reducing the cognitive load and complexity of managing multiple separate displays or calculations while maintaining comprehensive monitoring capability.

Inventive Principle:
Principle #5Merging (Combining)

3Measurement precision

If real-time calculation of associated control parameters is implemented, then ventilation control precision is improved, but computational requirements and system complexity increase

Engineering Contradiction:

Solution Approach 1:

The system performs self-service by automatically calculating associated control parameters (such as tidal volume, respiratory rate, minute ventilation) from the monitored respiratory parameters without requiring manual computation by the clinician. The processor automatically derives these parameters and displays them in the visual graph, improving precision while minimizing the added complexity through automated computation.

Inventive Principle:
Principle #25Self-service
