  • The HYVAN is ideal for anaesthetists who require a compact, portable and reliable anaesthetic machine. It is simple to use and can be easily serviced in a district hospital workshop.
  • The rugged design and quality build ensures years of trouble free service.
  • The HYVAN is a circle based anaesthesia machine. It has oxygen and air flowmeters and a selectatec back bar for plenum vapourisers.
  • The body is built from durable high impact plastic polymer.
  • The HYVAN is manufactured in an ISO certified factory in Christchurch, New Zealand. It is due to be CE marked in 2018.
  • The HYVAN is simple and safe to use.
  • The 'bag-in-bottle' bellows ventilator is driven by a high pressure gas source (eg pipeline,cylinder, compressor or oxygen concentrator).
  • In the absence of compressed gas, the ventilator can be manually operated for long periods. However a supply of oxygen (ie 1-2 litres/minute) is required.
  • A variety of plenum vapourisers and soda lime canisters can be used. The selectatec back bar is height adjustable to fit most plenum vapourisers. The soda lime canisters can be changed during an anaesthetic.
  • The HYVAN is suitable for adult and paediatric use. Air and oxygen flowmeters are fitted and gases can be supplied from piped medical gases, cylinders or an oxygen concentrator.
  • The HYVAN is suitable for spontaneousluy breathing or ventilated patients.
  • The HYVAN weighs 9 kg (16 kg with soda lime canister + vapouriser). It can be easily carried by one person and is designed to function in challenging environments.
  • Our goal is to build a top quality anaesthetic machine at an affordable price.
  • The HYVAN is currently undergoing CE mark certification (expected 2020).   The HYVAN is WAND registered in New Zealand (130910-WAND-6G5V6G). The HYVAN complies with ANZCA PS54 
  • HYVAN ANAESTHESIA LIMITED is ISO 13485 certified.

  • A HYVAN 9A monitor is also available with ECG, NIBP, SpO2, Temperature and gas bench (capnography and volatile agent measurement). The gas bench can be either sidestream or mainstream. BIS is available on the HYVAN 5A monitor.

About Dr John Hyndman and Ivan Batistich

 IMG 0594 


Dr John Hyndman is a New Zealand Specialist anaesthetist. Whilst working as a volunteer anaesthetist in developing countries he recognized that the anaesthetic equipment was unsatisfactory. The high technology equipment used in the developed world was not appropriate for developing countries. What was needed was an affordable, high quality, reliable anaesthetic machine that could be serviced in hospital workshops. It had to be simple to use and robust. In 2003 John Hyndman and Ivan Batistich decided to design and build such a machine. Sixteen years and six prototypes later they are finally satisfied that they have achieved their objective (The HYVAN). In 2016 the HYVAN was awarded the WFSA inaugural innovation prize.

Ivan Batistich is a New Zealand engineer. He has spent a life time developing and marketing anaesthetic products. In 1990 he designed and manufactured a ventilator (the IVENT). This ventilator is still in widespread use throughout the world and is renowned for its simplicity, reliability and longevity. Ivan and John decided to build an anaesthetic machine of a similar quality and reliability. The HYVAN is the result and it combines the proven (upgraded) Ivent ventilator with a soda lime absorber and selectatec mounted vaporizer.
