LSU Device Test Video

Prepared for emergency situations

For the assurance you need, the LSU device test will tell you in 10 seconds whether the LSU is ready for use in the field. The test includes four important requirements for the LSU to pass.

  • Blockage in the Suction System
  • Vacuum build-up efficiency
  • Maximum achievable vacuum level
  • Air leakages in the Pump System

As the Laerdal Suction Unit automatically charges when connected to an external power source, and charges to 80% after just 3 hours, it is ready for use when needed.


Effective at improving patient safety

For ease of use in difficult situations, the LSU has a built in suction indicator, with colour coding, to help ensure the correct vacuum strength is selected for children.

This feature, combined with the extra-large dial for ease of use with large gloves, the LSU enables providers to quickly select the correct amount of suction for any given situation.

The display also monitors:

  • Power ON Indicator
  • External Power Indicator
  • Battery level Indicator
  • Vacuum Indicator
  • Failure Mode Indicator: LED is lid if a malfunction has been detected
