The Dräger Evita 4 is an advanced intensive care mechanical ventilator designed to provide respiratory support for adult, pediatric, and neonatal patients. Its modular architecture, full-color display, and microprocessor-controlled ventilation platform allow it to support a broad range of invasive and spontaneous breathing applications in critical-care environments.
This refurbished Dräger Evita 4 ventilator offers multiple ventilation strategies, including IPPV/CPPV, SIMV, MMV, BIPAP/APRV, CPAP and assisted spontaneous breathing. Advanced functions such as AutoFlow, apnea ventilation, intrinsic PEEP measurement, compliance monitoring and MEDIBUS connectivity support comprehensive clinical ventilation management.

Core Ventilation Modes
| Mode |
Description |
| IPPV / CPPV |
Intermittent or continuous positive pressure ventilation, with optional AutoFlow |
| SIMV |
Synchronized intermittent mandatory ventilation using volume- or pressure-controlled breaths |
| MMV |
Mandatory Minute Volume ventilation |
| BIPAP / APRV |
Biphasic positive airway pressure / airway pressure release ventilation supporting spontaneous breathing |
| SB |
Spontaneous breathing |
| CPAP |
Continuous positive airway pressure |
| ASB |
Assisted spontaneous breathing / pressure support |
AutoFlow Technology
The AutoFlow function automatically regulates inspiratory flow during volume-controlled ventilation.
This allows the ventilator to adjust inspiratory flow according to the selected ventilation requirements while maintaining the intended volume-controlled ventilation strategy.
Monitoring & Waveforms
The Evita 4 provides real-time visualization and measurement of important respiratory parameters.
Waveform Display
The system can display:
- Pressure curves
- Flow curves
- Volume curves
Measured Parameters
The supplied specifications include monitoring of:
- Expiratory minute volume
- Tidal volume
- Oxygen concentration
- Breathing-gas temperature
Respiratory Mechanics
Special functions include:
- Inspiratory hold
- Expiratory hold
- Compliance tracking
- Intrinsic PEEP / Auto-PEEP calculation
Safety & Backup Functions
Apnea Ventilation
If spontaneous breathing stops, the ventilator can automatically switch to mandatory ventilation as an apnea backup function.
Gas Supply Logic
The gas-supply system can automatically shift to an alternative functional gas input when a loss of line pressure is detected.
These functions are intended to provide additional operational safety during mechanical ventilation.
MEDIBUS Connectivity
The Dräger Evita 4 supports the MEDIBUS protocol for external data exchange.
Depending on the installed configuration and connected equipment, this can support:
- Ventilator data transfer
- External monitoring integration
- Clinical data acquisition
- System connectivity
