Focus of Dr. Wolf's research:

  1. Novel modes of ventilation in pediatric respiratory failure

  2. Means of assessing lung volume in critically ill patients

  3. Regional distribution of ventilation in children with acute respiratory distress syndrome (ARDS)

  4. Means of assessing regional lung volume in critically ill patients with the use of noninvasive imaging such as Electrical Impedance Tomography (EIT).

  5. Guiding mechanical ventilation in children with acute respiratory distress syndrome (ARDS) with non-invasive imaging.


Research goals:

  1. Reduce ventilator associated lung injury (VILI) in critically ill children with ARDS.

  2. Advancing novel modes of mechanical ventilation in clinical practice including Neurally Adjusted Ventilator Assist (NAVA), High Frequency Oscillatory Ventilation (HFOV), and Partial Liquid Ventilation.

  3. Measure and identify regional lung injury using Electrical Impedance Tomography (EIT).

  4. Guide mechanical ventilation using EIT to improve outcomes in children with ARDS.

Translational implications of research:

Our work is particular important since ARDS is a heterogeneous disease, and different areas in the lung are associated with atelectasis and overdistension, potentially leading to additional lung injury during mechanical ventilation. While ventilator support of ARDS is lifesaving, ventilator associated lung injury (VALI) adds significantly to the morbidity and mortality of patients with acute lung injury.
