The MRI-1 ventilator is a small animal respirator for imagers, designed for use in MRI and other high magnetic field environment.
This respirator for imagers comprises a set of remote, pneumatically operated, non-metallic valves.
The MRI-1 can operate by itself or can be controlled and/or monitored by a computer. Respiratory airflow is provided by an internal airpump. Alternatively, an external pressurized gas source can be attached (oxygen or anesthetic gas).
Setting up and operating the MRI-1 is easy. Only three controls are required. Respiratory rate is set in breaths/minute; the Flow rate is set using the front-panel flowmeter (and measured internally by a mass flowmeter); and the Percentage of Inspiration is set to establish the ratio of inspiration to expiration time (I/E ratio). All respiratory parameters are shown on the front-panel LCD display. The tidal volume and minute ventilation reflecting the current settings are also continuously displayed, and can easily be changed by adjusting the Flow rate.
