First ultrasound diffusion
system on the market

PowerCube Diffusion+

Diffusion and distribution disturbance in one measurement

GANSHORN PowerCube Diffusion+ is the first diffusion system on the market that uses ultrasound technology. Its long-life sensor technology is based on a GANSHORN innovation and requires no maintenance. In addition, the high-speed sensor allows the user to change the ejection and withdrawal volume to measure patients up to 0.5 l VC.

GANSHORN PowerCube Diffusion+ combines calibration-free ultrasound sensors with the gas sensors specially developed for fast diffusion analysis, they form the basis for meaningful measurements. Precise analyzers enable the high-resolution display of wash-in curves for CO and helium. Diffusion and distribution disturbances thus become easily visible. The CO diffusion system with demand valve used is economical in sample gas consumption, enabling economical and effective operation.

For a reliable evaluation of the diffusion capacity, PowerCube Diffusion+ determines the TLCO (carbon monoxide transfer factor) and helium FRC SB (ERS/ATS standards) . In addition, the exhaled concentration of CO and helium is continuously displayed, allowing precise discrimination of dead space and alveolar plateau.


Intelligent Demand Valve (IDV)
Physical high pressure; volume controlled; IDV optimizes gas consumption and reduces cost per test

PowerCube Diffusion+ cable connection

Powerful software
User-friendly and intuitive
LFX software

3D swivel arm
Flexible, height-adjustable interface that also allows tests to be performed outside the cabin

Breathing in real time
Test is performed without breath holding, patient must exhale very slowly

Single-breath diffusion

Precise analyzers enable high-resolution display of wash-in curves for CO and helium. The PowerCube Diffusion+ with demand valve is economical in sample gas consumption. The long-life multigas sensor provides highly accurate and fast CO results, facilitating the determination of both single-breath and on-line diffusion processes. The PowerCube Diffusion+ is available as a stand-alone unit or integrated with the PowerCube Body+.

Single breath diffusion is a non-invasive method for determining:

  • Diffusion capacity [DLCO in mmol/min/lkPa]
  • Alveolar volume [VA in l]
  • Total lung capacity HE [TLC HE in l]
Advantages of PowerCube Diffusion+
  • Fast semi-automatic gas calibration
  • Real-time molar mass
  • helium analyzer
  • immediate diffisuion results
  • Gas analysis by long-life real-time analyzers with only one gas cylinder (CO, He)
  • Maintenance and spare parts free
  • Breathing bag free – gas uptake is regulated and waste is eliminated
  • ATS/ERS guidelines – Fully compliant with gold standards
  • Easy to use – change mouthpiece and go
