Respiratory Pressure Controller Sleep Onset Bridging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current respiratory disorder treatment devices often fail to provide optimal comfort, cost-effectiveness, and ease of use, particularly in managing sleep-disordered breathing events, as they do not adapt pressure settings dynamically with sleep onset detection.
Innovation Solution
A medical device comprising a pressure controller with a processor that initiates treatment with a pre-sleep pressure profile, transitions to a bridging profile upon sleep onset detection, and adjusts pressure to a therapeutic level, ensuring comfortable and effective treatment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If therapeutic pressure is applied immediately upon initiation of treatment, then treatment efficacy is improved, but patient comfort deteriorates making it difficult to fall asleep
Solution Approach 1:
The device applies a pre-sleep pressure profile that delivers lower pressure support during the initial phase before sleep onset. This preliminary action allows the patient to fall asleep comfortably without the discomfort of full therapeutic pressure, while still providing some respiratory support. Once sleep is detected, the device transitions to the full therapeutic pressure profile.
2Ease of operation
If pressure is reduced during initial phase to improve comfort, then patient comfort is improved, but treatment efficacy may be compromised
Solution Approach 1:
The device dynamically adjusts pressure support based on the patient's sleep state. During the pre-sleep phase, lower pressure is applied for comfort. Upon detection of sleep onset through analysis of respiratory patterns, the device automatically transitions to the full therapeutic pressure profile, ensuring treatment efficacy is achieved during the period when it is most needed.
Solution Approach 2:
The device continuously monitors respiratory parameters to detect sleep onset. This feedback mechanism allows the device to determine when the patient has fallen asleep and automatically switch from the pre-sleep pressure profile to the therapeutic pressure profile, ensuring treatment efficacy is maintained at the appropriate time.
3Measurement precision
If device monitors respiratory parameters to detect sleep onset, then treatment precision is improved, but device complexity increases
Solution Approach 1:
The device uses the patient's own respiratory parameters, already being monitored for therapy delivery, to detect sleep onset. By analyzing existing data on respiratory rate, tidal volume, and breathing patterns, the device determines sleep state without requiring additional dedicated sensors or complex external monitoring equipment.

AI summary
The invention relates to an apparatus for treating a respiratory disorder comprising a pressure device, and a controller, including at least one processor, configured to control the pressure device to: supply, upon initiation of treatment in a pre-sleep mode, a flow of pressurised air to the airway of a patient at a treatment pressure that commences at a pre-sleep pressure and varies according to occurrences of sleep disordered breathing events; when a timer reaches a timer limit in the pre-sleep mode, transition from the pre-sleep mode to a bridging period, and, during the bridging period, increase the treatment pressure to a predetermined therapeutic pressure according to a bridging profile of pressure versus time, wherein the bridging profile comprises a linear increase to the predetermined therapeutic pressure; and supply, in a therapy mode following the bridging period, the flow of pressurised.
