Solution Overview
Problem
Current respiration devices lack a reliable and straightforward method for recognizing Cheyne-Stokes respiration, which is characterized by alternating phases of hypoventilation and hyperventilation, often induced by cardiac insufficiency, making it difficult to monitor and manage effectively.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If complex event analysis methods are used to recognize Cheyne-Stokes respiration, then measurement precision improves, but device complexity increases
Solution Approach 1:
The patent extracts and focuses specifically on period length as a single critical parameter for detecting Cheyne-Stokes respiration, rather than analyzing multiple respiratory parameters simultaneously. The monitoring unit is designed to identify and measure only the time intervals between successive respiratory events, simplifying the detection mechanism while maintaining high accuracy in recognizing the characteristic periodic pattern of Cheyne-Stokes respiration.
Solution Approach 2:
The patent applies preliminary action by pre-defining the detection criterion (period length deviation less than 40%) for Cheyne-Stokes respiration recognition. The monitoring unit is configured in advance to automatically compare consecutive period lengths and register the presence of Cheyne-Stokes respiration when the deviation threshold is met, eliminating the need for complex real-time analysis algorithms.
2Device complexity
If simple detection methods are used, then device complexity decreases, but reliability of detection worsens
Solution Approach 1:
The patent replaces complex mechanical or algorithmic analysis systems with a simplified computational approach. Instead of using sophisticated signal processing or multiple sensor arrays, the invention uses a straightforward digital comparison method: the monitoring unit stores a previous period length value and automatically compares it with the current period length, registering Cheyne-Stokes respiration when the deviation is less than 40%. This substitution of complex mechanical analysis with simple digital computation achieves high reliability with minimal device complexity.
3Measurement precision
If multiple respiration parameters are monitored simultaneously, then measurement precision improves, but loss of time increases
Solution Approach 1:
The patent extracts and isolates period length as the single most critical parameter for detecting Cheyne-Stokes respiration, eliminating the need to process multiple respiratory parameters simultaneously. By focusing exclusively on time interval measurements between successive respiratory events, the system achieves accurate detection without the time-consuming overhead of analyzing flow rate, volume, pressure, or other respiratory parameters.
