Determination of the Prevalence and Severity of Expiratory Flow Limitation in Chronic Obstructive Pulmonary Disease Patients

The Vector ventilator is intended to provide non-invasive ventilatory support to treat adult patients with Obstructive Sleep Apnea (OSA), or Respiratory Insufficiency with the primary cause being COPD. This device is not intended for life support. It may be used to screened for the presence and abolishment of expiratory flow limitation. It is intended to be used within the home, institution/hospital, and diagnostic laboratory environments. The vector ventilator will titrate and treat EFL using non-invasive ventilatory support.

The Resmon Pro uses the forced oscillation technique (FOT) which is a noninvasive method to measure the mechanical properties of the lung and airways during tidal breathing. In addition to measuring total impedance (resistance and reactance), the Resmon Pro can measure expiratory flow limitation which is a key index of respiratory obstruction
