Anesthesia: Inhalation vs. Injectable
There are five basic considerations when choosing a method of anesthesia.
- Reduce the likelihood of animal loss
- Avoid interfering with research question
- Minimize the stress to animals
- Maintain a consistent plane of anesthesia through the duration of the procedure
- Have a fast and safe recovery at the end of anesthesia
Upon evaluation of a number of variables, inhalation anesthesia offers many advantages over traditional injectable anesthesia, as seen in the chart below

The SmartFlow Anesthesia Suite provides an effective alternative to traditional injectable anesthesia, while offering a simple and safe environment for the researcher.
How It Works
The SmartFlow Anesthesia Suite's sophisticated design ensures safe and easy anesthesia administration. Flow rates are fixed for each breathing device, eliminating complex calculations and adjustments during procedures as is common with injectable anesthesia as well as traditional inhalation anesthesia systems. Simply specify the concentration and which breathing devices need to be used, and the SmartFlow Anesthesia suite does the rest.
- Oxygen flows from the Oxygen tank into the vaporizer
- Oxygen mixes with Isoflurane producing a specified concentration of gas anesthesia
- Gas anesthesia of a specified concentration flows out at the correct rate for each breathing device
- Gas anesthesia keeps mouse asleep during procedure
- Excess gas is captured by a charcoal filtration device

SmartFlow Anesthesia Suite
LI-COR Biosciences SmartFlow Anesthesia Suite is the most advanced inhalation anesthesia design available. The innovative design ensures accurate gas flow for up to five different breathing devices with the simple flip of a switch, eliminating the complex and error prone calculations required on manual systems associated with adjusting the flow rates for multiple breathing systems. Unlike traditional systems, the SmartFlow system accurately controls the flow rate of oxygen for each breathing device which reduces overall costs by more efficient use of oxygen and Isoflurane.
The system accommodates an induction chamber plus up to four other breathing units (e.g. Pearl Impulse, Docking Station, Surgical Suite plus the Odyssey MousePOD Accessory).
Benefits include:
- Preset flow rates reduce the usage of Isoflurane and eliminates the need for flow meters and manual adjustments
- Easy to use on/off switches reduce the chances for operator errors
- Flow rate is not impacted by the number or type of accessories attached to the unit
- Consistent flow rates are obtained over distances greater than 100 feet
- Broad worldwide compatibility with either a 120V Model or 230V Model
SmartFlow Anesthesia Suite Includes:
- SmartFlow Vaporizer Unit
