Description
266388/ are sheared and can be expectorated or removed with suction. After the exhale, the system pauses and maintains a resting positive pressure flow to the patient. A facemask or mouthpiece can be used on endotracheal and tracheostomy (i.e. for patients with an appropriate adapter).
Preferably, the cough assist device automatically adjusts characteristic therapy levels (frequency, intensity, length of therapy, inhalation pressure, exhalation pressure) based on the levels of tidal volume, minute ventilation, and respiratory rate during therapy. In addition, the general within session and the session-to-session lung performance can be tracked to demonstrate effectiveness of the therapy (before, during, and after and across many sessions). Graphs could be provided to document breathing characteristics of the patient and to demonstrate improvement to the patient over time.
In addition, the characteristic shape of the bioimpedance expansion curve is an indicator of the success of each individual cough. Appropriate curves for maximizing exudate removal can be identified and the adjustment levels of the Cough assist System (frequency, intensity, length of therapy, inhalation pressure, and exhalation pressure) can be adjusted to get the desired cough expulsion curve. Characteristics of the cough assist can be adjusted to ensure the optimal results are provided for each individual patient.
Other embodiments and technical advantages of the invention are set forth below and may be apparent from the drawings and the description of the invention which follow, or may be learned from the practice of the invention.
Other embodiments and uses of the invention will be apparent to those skilled in the art from consideration of the specification and practice of the invention disclosed herein. The term comprising, where ever used, is intended to include the terms consisting and consisting essentially of. Furthermore, the terms comprising, including, and containing are not intended to be limiting. It is intended that the specification and examples be considered exemplary only with the true scope and spirit of the invention indicated by the following claims .
