Dynamic Hyperinflation Syndrome in Severe Asthma

The CZcams video on the detection and management of Dynamic Hyperinflation Syndrome (DHS) in severe asthma on mechanical ventilation is a tutorial that explains how to detect and manage DHS in patients with severe asthma, with a focus on prolonging the expiratory time to improve it.
The video begins by providing an overview of DHS and its impact on respiratory function in patients with severe asthma on mechanical ventilation. The instructor then explains how to identify DHS by monitoring airway pressures, and flow shape in expiration.
The video then focuses on the management of DHS on the ventilator and go over the steps used to prolong the expiratory time and allow the lung to fully exhale to reduce air trapping in the lungs. The instructor describes how to adjust ventilator settings, such as maximizing inspiratory flow time, decreasing the respiratory rate, tidal volume, and decreasing the inspiratory to expiratory (I:E) ratio, to prolong the expiratory time and improve DHS.
