Methods and devices for assessment of pneumostoma function
First Claim
1. A method for assessing function of a pneumostoma in a chest of a patient, the method including:
- (a) receiving an elevated-exhalation-pressure control device into the patient'"'"'s mouth;
(b) inserting a gas collection device into the pneumostoma;
(c) assessing qualities of gas in the pneumostoma during a time period in which a patient is exhaling at an elevated pressure through the elevated-exhalation-pressure control device; and
(d) removing the gas collection device from the pneumostoma.

Abstract
A pneumostoma assessment and treatment system includes methods and devices for aftercare of a pneumostoma. In particular, methods and devices are provided for standardized monitoring and assessment of pneumostoma patency thereby facilitating the establishment of standards-based protocols for pneumostoma management. Methods of standardized pneumostoma patency assessment includes the use of devices for raising alveolar pressure to a controlled repeatable pressure above ambient while analyzing gas flow through the pneumostoma. In response to an assessment the functionality of the pneumostoma, the tissues of the pneumostoma may be treated with a treatment device utilizing one or more different modalities to preserve or enhance the health and function of the pneumostoma.

10. A system for assessing pneumostoma function of a pneumostoma of a patient, the system comprising:
-
an airway interface adapted to make a seal with a natural airway of a patient; a pressure elevating system coupled to the airway interface which elevates a pressure of gas in the airway interface; a pneumostoma interface having a seal and a gas collection tube; a gas analyzer coupled to the pneumostoma interface wherein the gas analyzer measures at least one quality of gas in the pneumostoma during a period of time when the patient is exhaling and the a pressure of gas in the airway interface is elevated; and a display for displaying an assessed quality of gas measured by the gas analyzer. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19)
