For a functional unit the core system requires a suitable ventilation system. For only positive ventilation a mouse ventilator can be used. If positive and sub-atmospheric pressure ventilation is required, the Ventilation Control Module must be purchased.

Positive and Sub-Atmospheric (Negative) PressureVentilation with Ventilation Control Module (VCM)

• Used to control the ventilation of the isolated lung preparation. Allows for the physiological negative pressure ventilation of the lung and positive ventilation during preparation.
• 30 to 100 breaths per minute.
• I:E ratio can be set between 10 and 90% in 10% steps.
• End-inspiratory, end-expiratory, sigh, positive and negative pressures can be individually set.
• The TCM Timer Counter Module allows periodic sigh (hyperinflation) breaths to minimize edema formation.
• An adapter to supply the trachea with a gas mixture different than roomair during negative ventilation can be added.

* Negative pressure ventilation with a pressure regulator (73-4293) built into the VCM-R requires a pressurized gas supply from a tank or house air in the range of 2 to 8 barS (29 to 116 PSI).

** The Pressure-Free Gas Supply Adapter (73-2789) is only for use during sub-atmospheric pressure ventilation with either the VCM-P or VCM-Rand is used to supply alternative gas mixtures to the lungs.

Positive Pressure Ventilation Only

If only positive pressure ventilation will be used, choose an option below.

• Ventilation rate from 60 to 400 breaths per minute.
• Stroke volume 30 to 350 μl, simple adjustment while running.
• Compact size allows positioning close to system for minimal system volume.
