The UCL-Ventura breathing aid is a Continuous Positive Airway Pressure (CPAP) device (“the CPAP”). The CPAP supports patients with breathing difficulties. It works by pushing an air-oxygen mix into the mouth and nose at a continuous pressure, keeping airways open and increasing the amount of oxygen entering the blood stream. This breathing aid can be used to help Covid-19 patients with serious respiratory problems to breathe more easily and has been shown to help prevent the need for invasive ventilation.
This CPAP has been developed as a collaboration between UCL, University College London Hospital and Mercedes-AMG High Performance Powertrains. The design is based on an existing off-patent CPAP system that has been further modified to optimise oxygen consumption. It is hoped that, by making this information widely available, this may help the global response to the crisis by enabling healthcare systems around the world to provide respiratory support for patients with Covid-19. More information can be found on the UCL-Ventura website.

This CPAP has been approved for manufacture by UCL by UK regulators, the Medicines and Healthcare products Regulatory Agency (MHRA) under special conditions. These conditions state that this is a non-CE marked CPAP, given approval for use in the NHS for the interest of public health protection under the Covid-19 pandemic emergency. Please note that UCL’s MHRA approval is time limited and ends on whichever of the following dates occurs soonest:
a) 1st October 2020;
b) The date when the device is CE marked; or
c) There is no longer a need for the device in the treatment of COVID-19 patients.
Any manufacture and use of this CPAP by third parties must require the third party to have local regulatory approval in place, as required in the third party’s own country and must fully comply with any stipulated conditions, laws and regulations that ensure full patient safety.
The technical specifications for this CPAP are being shared for humanitarian purposes, to help support the international community addressing pressing demands to care for Covid-19 patients. This is not a business venture. There is an expectation that those using these specifications to manufacture these devices follow the same guiding principles.
The instructions for manufacture should be followed precisely to ensure quality and safety, with no deviations or substitutions.
All hospitals must work with their O2 engineering teams and ascertain their VIE outflow and downstream flows and pressures to specific ward areas before deploying these devices. Healthy patient evaluation data indicates O2 flow rates of 11, 14, 17 l/min for inhaled oxygen (FiO2) levels of 30, 40, 60%, respectively for calm breathing and O2 flow rates of 14, 25 and 46 l/min at FiO2 of 30, 40, 60%, respectively for heavy breathing.
Access to the design and manufacturing instructions package is by licence, which will be granted at no cost to governments, relevant industry manufacturers, academics and health experts. To help ensure relevance and legitimacy, users must make their requests for a licence using their work, university or institution email address.
