Cardinal Health Vela Ventilator

The VELA Ventilator, made in 2008, is a software driven and easy to use ventilator, with a full-function turbine gas delivery system and microprocessor control through a Graphical User Interface that provides support for pediatric to adult patients. The VELA may be configured as a conventional ventilator or non-invasive positive pressure ventilator (only available with VELA+ and VELA Comprehensive).

The VELA comes in three models: VELA, VELA+, and VELA Comprehensive. This guide is intended for the base model VELA, but may also be used with the VELA+ and VELA Comprehensive.

The VELA Ventilator is blue and has a touch interface. it is 13” W x 14.5” D x 12” H, and weighs ~38 lbs. To be sure that your ventilator is a VELA, make sure that there is the VELA marking on the front face of your device.

The ventilator provides 4 signals at the analog output connector

• Airway Pressure
  • Range: -60 to 140 cmH2O
  • Scale: 1 cmH2O / 25 mV
  • Accuracy: ±50mV or ±5% of reading, whichever is greater
  • Zero Offset: 1.5 VDC at 0 cmH2O
• Flow
  • (Inspiratory/Expiratory)
  • When selected the ventilator provides a continuous analog voltage representative of inspiratory flow minus expiratory flow
  • Range: -100 to 200 LPM (Adult)
  • Scale Factor: 1 LPM / 10 mV (Adult)
  • 1 LPM / 25 mV (Pediatric)
