APPARATUS, SYSTEM AND METHOD FOR ASSESSING ALVEOLAR INFLATION

摘要

A system and method for measuring alveolar performance during ventilation using a microphone positioned adjacent to the distal end of a ventilation tube. The microphone is connected to a monitor that filters the signals received from the microphone to eliminate unwanted noise, such as that caused by the heart and turbulent airflow through the large airways of the lungs. The desired signals are then amplified and displayed on a graph as a function of lung volume during inflation. A clinician may take appropriate ventilation strategies based on the results displayed by the system to avoid ventilator induced lung injuries and decrease the mortality rates of patients having acute respiratory distress syndrome.
