 The insufflator was successful in driving air to the TEP.  The regulator was capable of limiting the air pressure to below 1 PSI, although fine tuning is necessary due to the regulator valve operating in a range of 0 to 5 PSI.  0 to 1 PSI regulator valves are not commercially available.  The valve door on the TEP opens partially when air is driven, indicating the regulator valve is capable of minute adjustments.  In tests, the duration of constant TEP insufflation was remarkably short, averaging approximately three minutes before the cartridge was expended and had to be swapped out.  This is due to the small volume of the CO2 canister in which although it is highly portable, its life span is small.  Larger CO2 canisters can be used, but portability of the device will be reduced. The insufflator was successful in driving air to the TEP.  The regulator was capable of limiting the air pressure to below 1 PSI, although fine tuning is necessary due to the regulator valve operating in a range of 0 to 5 PSI.  0 to 1 PSI regulator valves are not commercially available.  The valve door on the TEP opens partially when air is driven, indicating the regulator valve is capable of minute adjustments.  In tests, the duration of constant TEP insufflation was remarkably short, averaging approximately three minutes before the cartridge was expended and had to be swapped out.  This is due to the small volume of the CO2 canister in which although it is highly portable, its life span is small.  Larger CO2 canisters can be used, but portability of the device will be reduced.
