 the supply chain of ventilators in the need across the world, it's pretty tight. It will be very difficult to get ventilators in a very timely fashion to have an impact on the patients and that's why you're hearing these partnerships to be able to gear up that and address the shortage of ventilators. APRV or Airway Pressure Release Ventilation is a mode of ventilation which is designed to open up an inflamed lung and to keep it open. APRV is medically advised. It's not something that you would just put a patient on for a brief period of time in desperation while you're waiting for a better option. It's actually something that they could potentially be on for hours to days continually as a therapy to allow their bodies to try and recover from the inflammation caused by COVID-19. This effort has really expanded into something fairly substantial and in only three weeks or one day less than three weeks it's been quite mind-blowing actually. Certainly one of the most extraordinary experiences of my professional life. And you're seeing in countries you know China, Italy, Spain today was reported 10,000 you know plus individuals died in the United States here the numbers are increasing over and over of deaths related to COVID-19. So the impact is absolutely critical right now. We can have some small impact on saving the life. I think that that's what this is about.
