| 20090253995 | CLINICAL MONITORING IN OPEN RESPIRATORY AIRWAYS - A novel and non-obvious method, system and apparatus for determining respiratory volume flow rate of a subject and associated parameters such as tidal volume, minute volume, and respiratory rate. The method for determining respiratory volume flow rate of a subject can include selecting an airway cavity of the subject, measuring delivery volume flow rate of respiratory gas delivered to the airway cavity, measuring pressure within the airway cavity and calculating a respiratory volume flow rate of the subject using the measured delivery volume flow rate of respiratory gas delivered to the airway cavity and the measured pressure within the airway cavity. The method further can include generating a warning signal selected from the group consisting of an indicator that a respiratory volume flow value is outside of an expected value for the subject and an indicator that an airway cavity measurement value does not conform to an expected value. | 10-08-2009 |
