SpiroAir Features & Specifications

Test Capability

SpiroAir has a small footprint and can be comfortably set on a bench or supplied with a durable mobile cart.

SpiroAir has been scientifically designed to be an instrument of impeccable accuracy and clinical background. This is an affordable high quality research caliber system that is truly capable of respiratory measurement in cases of severe disease.

SpiroAir tests Simple Spirometry, Flow Volume Loops, MVV, Lung Volumes by either helium dilution (FRC) or nitrogen recovery (TLC), Single Breath Diffusion, Membrane Diffusion and Capillary Blood Volume, Respiratory Pressures (MIP and MEP), Bronchial Challenge Testing (Methocholine, Exercise or Cold Air), Manual Entry for ABG's, Exercise and much more.

Ergonomic Patient Valve

The valve support arm is easily adjusted to suit optimum sitting heights.

The SpiroAir pneumatic valve has been designed for long life and minimum preventative service. The valve cleverly caters to the requirements of all available tests affording a single patient connection yet maintaining a minimal deadspace. There is no need to frequently change unreliable balloon valves with SpiroAir! Utilizing a direct piston drive, the valve is suitable for thousands of quiet trouble free operations.

For helium dilution studies, an incorporated pneumotach allows for automatic "switch-in" at end-tidal expiration.

Although the valve is usually isolated by a bacterial/viral filter, disassembly for cleaning is a breeze!

Respiratory Pressures

Maximum inspiratory and expiratory pressures can be measured while seated at the patient valve. ComPAS Freedom™ provides for measurement and storage of MIP and MEP when performed at FRC as well as the traditional TLC and RV condition.

Single Breath Diffusion

The SpiroAir spirometer is easily to provide access for cleaning.

SpiroAir has been designed to assure reproducible DLCO results without any "computer enhancing" or manipulation of component variables (i.e. volume, time or gas analysis). The patient breathes from a gas reservoir at atmospheric pressure thus avoiding problematic interference of a demand valve. The sample circuit and collection bag are automatically tested for any leaks prior to each test. Gas sampling and test performance are reviewed to confirm clinical validity of each effort.

Measurements of DLCO on SpiroAir adhere to the standards on which predicted equations are based. Both the DLCO and VA (Alveolar Volume) data are highly reproducible and can be relied on for clinical interpretation. ComPAS Freedom™ software also provides correction of DLCO and DL/VA for lung volume.

Helium Dilution Lung Volumes

Helium dilution testing has been optimized in this remarkable new design. The 12 liter spirometer not only self-centers for routine spirometry and flow volume studies but also automatically fills, empties and flushes in a very short period during closed-circuit mode.

The background mixture for helium dilution testing is automatically mixed by connection to cylinders of 100% He and 100% O2. Utilizing the two cylinders of 100% mixture saves considerable cost in test gas.

While the whisper-quiet turbines direct air around the closed-circuit, carbon dioxide is scrubbed by a chemical absorber. Oxygen balance is maintained by both fast response oxygen analysis and absolute volume baseline monitoring thus ensuring calm comfort for patients of all size and condition.

SpiroAir and ComPAS Freedom™

Each flow volume maneuver is assessed for ATS acceptability. Using check-marks, the technician is immediately informed of reproducibility.   Helium dilution testing has never been easier. ComPAS Freedom™ takes care of the test setup and control of oxygen consumption so that your full attention can be on the patient.

ComPAS Freedom™

If you own the finest pulmonary system available, why not utilize the best in data management and network connected interpretation?

ComPAS Freedom™ Task Manger DiagramThe ComPAS Freedom™ Task Manger was created around the needs and requirements of one of America's most prestigious teaching hospitals. The versatility of the design makes the Task Manager equally suitable in high volume teaching centers or smaller pulmonary practices.

When tests are completed in the pulmonary lab, results can be routed to any network-connected station for physician interpretation. In cases where multiple physicians will interpret results, the Task Manger automatically sends the appropriate patient results to each physician.

Internal "Task Notes" can be attached to patient results and sent to colleagues. Tests can be routed to pulmonary fellows for preliminary review and then on to faculty staff for final interpretation. If reports need to be printed and sent to referring physicians, completed tests along with the interpretation can be forwarded to the department secretary for printing. In smaller centers, test results can be sent from the pulmonary lab directly to the attending physician. At his or her desk, the interpreting physician can log into the Task Manager and review a variety of customizable report formats and engage a personal template of interpretation text. The computer impression is available for referral as the interpretation is being considered.

ComPAS Freedom™ has a multitude of beautifully organized and graphical report formats. At Morgan Scientific, we pride ourselves in after sales customer support. The ComPAS Freedom™ license gives you access to experts in pulmonary measurement and report design. We will be pleased to customize a report around your particular preferences.

The Task Manager simply requires connectivity to the SQL database server. Further data distribution to hospital-wide information systems usually requires a specialized interface. Please contact us for further details.
