A composite pressure signal is generated comprising the sum of an airway pressure signal a gas flow pressure , signal obtained by applying a gain factor (Kf) to a signal representing gas flow rate and a gas volume pressure signal obtained by applying a gain factor (Kv) to a signal representing volume of gas flow. Kf </sb> and Kv values are adjusted to result in a desired linear trajectory of composite pressure signal baseline in the latter part of the exhalation phase. The current composite pressure signal is compared with (i) selected earlier composite pressure …

Why it's free to use
- Filed June 27, 2003 and granted February 11, 2014. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended June 27, 2023.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 27, 2025.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
