Flow Therapy System Predicting Safe Apnoea Duration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods lack a reliable way to predict the duration of safe apnoea during medical procedures like intubation and endoscopy, leading to interruptions for oxygen saturation maintenance and increased risk of hypoxia due to unpredictable apnoea duration.
Innovation Solution
A method and system that measure and determine the duration of safe apnoea by analyzing respiratory and physiological indicators such as carbon dioxide concentration, oxygen levels, lung volume, and airway pressure, using a processor to calculate and predict the safe apnoea time based on individual patient parameters and thresholds.

Engineering Contradiction Analysis
1Reliability
If pre-oxygenation is applied using a face mask to maintain oxygen saturation levels, then oxygen saturation is maintained, but the intubation process must be interrupted multiple times causing frustration and delay
Solution Approach 1:
The system performs preliminary calculation of the safe apnoea duration before intubation begins, allowing the medical professional to plan the entire intubation procedure within a single continuous timeframe without needing to interrupt for re-oxygenation. This is achieved by measuring lung volume and oxygen consumption rate prior to the procedure and using these values to predict the maximum safe apnoea duration.
2Productivity
If the duration of safe apnoea is not predicted, then the procedure can continue without interruption, but the patient is at risk of hypoxia due to unpredictable oxygen saturation decline
Solution Approach 1:
The system provides real-time feedback to the medical professional about the remaining safe apnoea duration during the procedure. By continuously monitoring lung volume and oxygen consumption rate, the system calculates and displays the remaining safe apnoea time, enabling the team to complete the intubation within the safe window and avoid hypoxia while maintaining continuous procedure execution.
3Measurement precision
If multiple indicators are measured to accurately predict safe apnoea duration, then prediction accuracy is improved, but the complexity of the monitoring system increases
Solution Approach 1:
The system extracts and focuses on measuring only the two most critical indicators for predicting safe apnoea duration: lung volume and oxygen consumption rate. By selecting and measuring only these essential parameters rather than attempting to measure all possible physiological indicators, the system achieves sufficient prediction accuracy while keeping the monitoring system relatively simple and manageable.
