To set up the SAR-830/AP, you first need to know the desired Tidal Volume (VT) and Respiratory Rate (RR). These can be determined from literature references, or from the charts at the back of our instruction manuals. Besides VT and RR, the other parameter you need is the Inspiration:Expiration Ratio, or IE. For rodents, this is often set as 40% (0.40), which allows for a slightly longer expiration phase. With these basic numbers in hand, the equations below will give the needed SAR-830/AP settings.  

First, determine Inspiratory Time (TI) in seconds:
TI = (IE X 60) / RR

Then, determine inspiratory Flow Rate in ml/min:
FLOW = (VT X 60) / TI

Note that VT is in ml, RR is in breaths/minute, TI is in seconds, and FLOW is in ml/minute. The equations account for the seconds & minutes automatically.

Here is an example for a 300g rat:
RR = 55 breaths/minute, VT = 2.5ml, and IE = 40% (0.40)

TI = (0.4 X 60) / 55 = 0.436s, and

FLOW = (2.5 X 60) / 0.436 = 344ml/min

On the SAR-830/AP ventilator, you would then dial in the RR directly using the RATE dial and the digital display. Adjust the flowmeter to the FLOW setting, and the INSP TIME dial for the TI setting. To adjust VT up or down from these settings, it is most convenient to simply increase or decrease the FLOW, while leaving the timing settings as is. 

The SAR-830/AP's legendary reliability rests on simple principles of operation and robust construction.  Tidal volumes are generated by gating a known airflow into the lungs for a set inspiratory time. Only three controls — respiratory rate, inspiratory time, and flow rate are necessary to produce tidal volumes and respiratory rates over a wide range. Our SAR-830/AP has the additional feature of pressure-cycling, where the lungs are always inflated to a set pressure on each inspiration. Compatible with Isoflurane Anesthesia systems.
