Control of flow and/or pressure provided by breathing apparatus
Summary
The USPTO granted Patent US12594390B2 to Fisher & Paykel Healthcare Limited covering methods and apparatus for controlling flow and/or pressure in breathing devices. The patent describes measuring baseline and current breath flow parameters (respiratory rate, tidal volume) and dynamically adjusting apparatus operation based on comparative analysis. The patent contains 18 claims across flow control, pressure regulation, and respiratory monitoring technology.
What changed
The USPTO issued Patent US12594390B2 to Fisher & Paykel Healthcare Limited for a breathing apparatus control system. The patent claims methods of operating a breathing apparatus involving measuring baseline breath flow parameters (respiratory rate and/or tidal volume), varying flow rate, measuring current breath parameters, comparing baseline and current values, and altering operation accordingly. The apparatus claim covers a breathing apparatus configured to implement these methods.\n\nManufacturers of respiratory therapy devices, CPAP/BiPAP apparatus, and ventilators should monitor this patent for potential infringement implications when developing flow-responsive or pressure-responsive breathing apparatus. Healthcare institutions using Fisher & Paykel respiratory devices may benefit from proprietary flow control improvements. Competitors in the respiratory device space should conduct freedom-to-operate analyses before commercializing flow-controlled breathing apparatus.
What to do next
- Monitor patent landscape for competing respiratory device technologies
- Review product development plans for potential licensing needs
- Assess freedom-to-operate for flow control features in breathing apparatus

Control of flow and/or pressure provided by breathing apparatus
Grant US12594390B2 Kind: B2 Apr 07, 2026
Assignee
Fisher & Paykel Healthcare Limited
Inventors
Stanislav Tatkov, Kevin Peter O'Donnell, Sheng Feng
Abstract
The invention comprises a method of operating a breathing apparatus comprising measuring a baseline breath flow parameter being respiratory rate and/or tidal volume or a parameter derived therefrom, varying the flow rate provided by the breathing apparatus, measuring a current breath flow parameter being respiratory rate and/or tidal volume or a parameter derived therefrom, comparing the baseline and current breath flow parameters, and altering operation of the breathing apparatus based on the comparison. The invention also comprises a breathing apparatus that implements the above method.
