Indicative Specification for a Rapidly Manufactured Ventilation System (RMVS)


PLEASE NOTE: Any interested supplier or for further clarity please contact 0300 456 3565 or email

The purpose of this document is to outline the key requirements for a Rapidly Manufactured Ventilation System (RMVS).

It is intended to enable Manufacturers to start the process of considering how they may be able to meet these requirements.  Working with manufacturers and clinicians we would expect to iterate this specification before finalization.

Whilst the key operating parameters are subject to change, they are not expected to differ significantly from those set out below.

The document does not attempt to provide a comprehensive list of requirements as manufacturers are already familiar with UK operating environment (e.g. power), acceptable materials and standard device safety considerations.

The document assumes that the reader is already familiar with the concepts and basic mechanics of Mechanical Ventilation devices.   The following links may be of assistance: (a description of a simple ventilator)   (a proposed system for a rapidly deployable ventilator)


The RMVS must:


  • Be reliable.  It must work continuously without failure (100% duty cycle) for blocks of 14days - 24 hours a day.  If necessary, the machine may be replaced after each block of 14 days x 24 hours a day use.


  • Provide at least two settings for volume of air/air O2 mix delivered per cycle/breath.  These settings to be 450ml +/- 10ml per breath and 350ml +/- 10ml per breath.


  • Provide this air/air O2 mix at a peak pressure of 350 mm H2O.


  • Have the capability for patient supply pipework to remain pressurised at all times to 150mm H20.


  • Have an adjustable rate of between 12 and 20 cycles/breaths per minute.


  • Deliver at least 400ml of air/air 02 mix in no more than 1.5 seconds.   The ability to change the rate at which air is pushed into the patient is desirable but not essential.


  • Be built from O2 safe components to avoid the risk of fire and demonstrate avoidance of hot spots.


  • Be capable of breathing for an unconscious patient who is unable to breathe for his or herself.  Ability to sense when a patient is breathing, and support that breathing is desirable but not essential.


  • Be able to supply pure air and air O2 mix at a range of concentrations including at least 50% and 100% Oxygen.  Oxygen shortages are notexpected, but the ability to attach a Commercial Off The Shelf (COTS) portable O2 concentrator machine may be a useful feature. 


  • Support connections for hospital Oxygen supplies – whether driven by piped or cylinder infrastructure


  • Be compatible with standard COTS catheter mount fittings (15mm Male 22mm Female)


  • Fail SAFE, ideally generating a clear alarm on failure.  Failure modes to be alarmed include (but are not limited to) pressure loss and O2 loss.


The RMVS must:


  • be intuitive to use for qualified medical personnel familiar with ventilator use.  Must not require extensive training to use effectively.    Relevant usage instructions must be attached / intrinsic to the device


  • be capable of being easily cleaned / decontaminated using readily available materials


  • have successfully been subjected to a testing and assurance process that is appropriate for the exceptional circumstances


  • have transparent design, supply chain, manufacture and testing processes that are of sufficient quality to enable MHRA officials to deem appropriate for usage in exceptional circumstances


  • not be excessively cumbersome so that it would impede hospital operations or prevent easy movement within hospital premises


  • be made from materials and parts readily available in the UK supply chain (anticipating increasing global restrictions on freight movement).



The Government have launched a new web form for businesses to complete who may be help with the response to coronavirus 

The support needed includes things like: 

  • medical testing equipment
  • medical equipment design
  • protective equipment for healthcare workers, such as masks, gowns and sanitiser
  • hotel rooms
  • transport and logistics, for moving goods or people
  • manufacturing equipment
  • warehouse or office space, for medical use or storage
  • expertise or support on IT, manufacturing, construction, project management, procurement, engineering or communications
  • social care or childcare

Businesses will be asked some questions about the type of support that can be provided and will be contacted as soon as possible if the support is needed.

The SparkFund programme may be able to support you through its Innovation Vouchers or Grants for Research & Development. For more information, please contact your innovation manager or if you are new to the SparkFund programme complete our enquiry form.
