Insufflation is the part of laparoscopy that everyone notices when it goes wrong. The Olympus UHI-3 was designed around that reality: maintain the set pressure with enough flow reserve to recover quickly from leaks, specimen retrieval and instrument exchange.

Flow reserve versus pressure ceiling
Two numbers describe an insufflator's behaviour: the maximum flow it can deliver and the pressure it will not exceed. High flow without accurate pressure control is unsafe; accurate pressure without flow reserve means the field collapses every time a trocar leaks. The UHI-3 balances both, which is why it is often chosen for longer procedures.
Where the efficiency gain comes from
- Faster entry: pneumoperitoneum is established in less time, shortening the interval before the surgeon can start.
- Stable field: flow recovery keeps working space constant during suction and instrument exchange.
- Fewer interruptions: teams spend less time waiting for pressure to recover.

Verification and maintenance
Verify displayed pressure against an external gauge at several set points, confirm the overpressure relief path operates correctly, and check that flow remains stable with a controlled leak. Replace tubing and filters at the interval specified for the unit, and keep the gas outlet free of debris.
Choosing between UHI-2 and UHI-3
For short routine cases, a well-maintained UHI-2 remains adequate. For long laparoscopic and robotic-assisted lists where field stability directly affects duration, the flow reserve of the UHI-3 usually justifies the investment.
FAQ
Does higher flow increase the risk of overpressure?
Not when the pressure limit is verified and the relief path works. Flow and pressure limiting are separate control functions.
What accessories are needed?
Approved insufflation tubing, a gas filter where specified, and a verified CO2 supply with adequate regulator performance.
