Positive and Sub-Atmospheric Pressure Ventilation :
- Used to control ventilation of the isolated lung preparation
- Supports physiological negative pressure ventilation of the lung
- Provides positive pressure ventilation during preparation
- Ventilation rate: 30 to 100 breaths per minute
- I:E ratio adjustable between 10% and 90% in 10% steps
- End-inspiratory pressure can be individually adjusted
- End-expiratory pressure can be individually adjusted
- Sigh pressure can be individually adjusted
- Positive pressure can be individually adjusted
- Negative pressure can be individually adjusted
- Timer counter function allows periodic sigh or hyperinflation breaths to help minimize edema formation
- Alternative gas mixtures can be supplied during negative pressure ventilation
- Gas flow can be adjusted using a needle valve
- Suitable for controlled ventilation during isolated lung experiments
Pressure-Free Gas Supply Adapter :
- Used to supply the trachea with a gas mixture different from room air during negative pressure ventilation
- Includes a needle valve for gas flow adjustment
- Suitable for alternative gas supply during sub-atmospheric pressure ventilation
Negative Pressure Ventilation Control :
- Available with an integrated pump for negative pressure ventilation
- Available with a pressure regulator for controlled negative pressure ventilation
- Pressure-regulated operation requires a pressurized gas supply
- Suitable gas supply pressure range: 2 to 8 bar (29 to 116 PSI)
- Supports alternative gas mixtures during sub-atmospheric pressure ventilation
Positive Pressure Ventilation :
- Designed for positive pressure ventilation applications
- Compatible with suitable small animal ventilators
- Includes an adapter for positive pressure ventilation
- Side port allows measurement of tracheal airway pressure during positive ventilation
