Patients on artificial ventilation need the air they breathe to be artificially humidified to prevent airway damage. The RespirAq active humidifier is a heated humidifier complete with an integrated filter that humidifies without the need for additional water. Within 100 milliseconds, the humidifier can switch between a super-hydrophilic state to capture moisture during expiration, and a super-hydrophobic state which returns the moisture during inspiration. The device has been designed to deliver 37°C fully humidified (95% relative humidity) respiratory gases for invasively mechanically ventilated patients.
The RespirAq active humidifier removes the need for bulky additional water supply, tubing and peripherals making it a remarkably elegant and compact solution for ventilated humidification.
As a high-performance humidification device, the RespirAq active humidifier achieves 35-40 mgH2O/L. The RespirAq has a minimal 14 ml of internal dead volume ensuring unimpeded CO2 clearance rates. With a pressure drop of 0.2 cmH2O at 30 lpm, 0.5 cmH2O at 60 lpm and 1 cmH2O at 90 lpm, The RespirAq active humidifier has a negligible effort to patient work of breathing. The RespirAq is a light weight 30g reducing the risk of pressure injury.
Adjustable setting allow for personalised and fine tuned Temperature and Humidity delivery. Innovation technology has resulted in a no ‘rainout’ humidifier with no condensation observed in real world testing.
The smart fabric at the core of the RespirAq active humidifier is the invention of Dr Sandra Grau Bartual a trained chemical engineer originally from Spain who completed her PhD that resulted in development of the smart fabric at AUT in 2019, in collaboration with her supervisor Professor Prof. Ahmed Al-Jumaily. Dr Grau Bartual has built the RespirAq team in collaboration with industry experts to include clinical, ISO 13485 Quality systems, human centred design, and manufacturing expertise.
The RespirAq team is based in Auckland, New Zealand. We welcome opportunities to contribute to research, innovation and are committed to building a vibrant start-up culture both in New Zealand and internationally.
