20130255691 | System and Method for Use of Acoustic Reflectometry Information in Ventilation Devices - The present disclosure relates to a system and method for use of acoustic reflectometry information in ventilation devices. The system and method includes a speaker to emit sound waves into an intubated endotracheal tube (“ETT”) and a microphone to detect returning acoustic reflections. In addition, the system and method includes a reflectometry device in communication with a ventilation device for analyzing timings and amplitudes of the returning acoustic reflections to determine a size of a passageway around an ETT tip, location and size of ETT obstructions, and relative movement of the ETT tip within a trachea. The reflectometry device is also configured to determine a resistance parameter representative of resistance to actual flow of air through the ETT based upon a function of the diameter of the ETT, length of the ETT, and percent obstruction of the ETT, where the resistance parameter is used to calculate the tracheal pressure. | 10-03-2013 |
20130228171 | LEAK DETECTION SYSTEM AND METHOD FOR TUBE OR CATHETER PLACEMENT - The present disclosure relates to a leak detection system and method for tube or catheter placement. The system and method includes acoustically sensing a leak in the seal between a tube or catheter within a body and the body cavity against which it is sealed, assisting the user in adjusting the system until the leak has been substantially sealed, and establishing system parameters to be used thereafter to maintain the system in an operating state that will substantially prevent leakage, all using a noninvasive acoustic technique. | 09-05-2013 |
