PFT Testing Excellence

The SpiroAir has a rich heritage from the very origins of pioneering pulmonary function design. The SpiroAir combines all of the renowned engineering features of the Morgan Transfer Test into a sleek modern instrument harnessing the finest transducers ensuring clinical excellence.

Test Capability

When it comes to spirometry, there is no higher standard of measurement than the low resistance rolling seal spirometer! The same spirometer is utilized for measurements of closed-circuit helium dilution FRC. From the test set-up to the elegant O2 delivery during each study, the SpiroAir ensures patient comfort and quality of lung volume measurement.

The same can be said for DLCO, Respiratory Pressures, Bronchial Challenge and Cough Peak Flow testing. This instrument truly sets a standard that few can match!

SpiroAir Features

  • Gold standard 12L rolling seal spirometer
  • Gold standard helium dilution FRC
  • Superb reproducibility across all tests
  • Pressure less delivery of DLCO gas
  • Quiet pneumatic piston valves
  • Automatic test preparation
  • Automatic spirometer centering
  • Very low maintenance requirement or cost

Simple to Use, Yet Research Grade

With ComPAS testing is as easy as 1, 2, 3…

  1. A simple touch on [Spacebar] begins all tests.
  2. When maneuvers are completed, the software checks the individual effort against ATS recommended PERFORMANCE criteria. If the effort meets these test standards, a hollow check mark provides visual confirmation.
  3. Once the appropriate number of tests meet both PERFORMANCE and REPRODUCIBILITY criteria, solid check marks appear confirming that ATS has been achieved.

Our lab has been using Morgan Scientific equipment for over 20 years. When I bought our first system there was no question that Morgan hardware and software was the superior product and this remains true today. The support from Morgan Scientific has been and continues to have no equal.

I know of no other medical instrument company that would allow you to speak directly with the person that wrote the software that you have a question about or would like a change made to. The staff has truly impressed us with their knowledge of their hardware, Pulmonary Physiology and more so their ability to communicate this to our staff.

We have tested over 30,000 patients with Morgan equipment, during this time there has never been a day that our lab has not been "up and running".

This company is recommended with no hesitation, they are not simply vendors they are part of our department, our partners and will continue to be for the foreseeable future.

I would be more than happy to speak with any potential customers regarding the Morgan Scientific equipment and the integrity of this company.
