The OHD Spirometer is powered by the most comprehensive spirometry software available. Its customizable design allows the user to easily adapt the performance to the level of sophistication required.
1. The OHD Spirometer exceeds all ATS (American Thoracic Society) 1994 "Standardization of Spirometry." Many of the current spirometers on the market do not have a letter from the LDS Hospital that validates meeting the new ATS 1994 standards. The LDS laboratory is currently the industry standard for ATS validation testing. The 1994 ATS recommendations address several new issues of Spirometry, namely diagnostic versus monitoring spirometers, multiple flow calibration of pneumotach based systems, the use of infection control filters, and correction for BTPS: normal body temperature, ambient pressure saturated with watervapor. To address the validation under 1994 ATS recommendations, the LDS laboratory added testing procedures, specifically BTPS correction testing using heated humidified air for accuracy testing “ because of potential problems associated with BTPS correction.” The data for the OHD spirometers by OHD exceed these recommendations.
2. The OHD Spirometer utilizes a BRASS "Fleisch-Type" pneumotach, proven in the industry to provide unparalleled accuracy and durability. The brass pneumotach gives better accuracy because of its unsurpassed ability to compensate for temperature and humidity changes. Most of the other Fleisch Type pneumotachs are made of plastic or of a disposable material, which are not as accurate as the brass type.
3. The OHD Spirometer has multiple predicted sets built into the software, including the new Hankinson (NHANES III) predictives, which were published in 1999. This new set of Hankinson predictives could be standard for most all occupational and industrial pulmonary function tests in the future.
4. The OHD Spirometer gives you side-by-side real-time
Flow/Volume Loop and Volume/Time graphics during an actual test. Many
of the current spirometers do not give any curves in real time but only when
printed. OHD feels it is very important to be able to view “both”
curves in real-time so that the user gets better results and better quality
assurance. The stand-alone spirometers only give the user the curve
when it prints or only the volume time curve on volume spirometers. The
technician needs to view the curve during the actual test.
5. The OHD Spirometer gives you multiple incentive graphics for
patient/employee coaching. If the user has an employee that is on the
borderline for respiratory clearance, the incentive can oftentimes get the user
over the minimums for respirator clearance. The visual incentive is
related to that person’s predicted normals, in order that a better effort and
therefore better results are achieved. We feel incentive graphics give you
better results on testing. We have seen as much as a 10% better effort
using incentives.
6. The OHD Spirometer utilizes a high precision multi-flow calibration
syringe. This increases accuracy, reproducibility, and ease of calibration.
Our multiflow calibration syringe gives the user the exact flow rates for each
calibration speed, and all the calibration records are stored for future
reference!
7. The OHD Spirometer has trend analysis of employee/patient results
built into the software. The benefit to you is that the user can
immediately trend a persons FVC, FEV1, FEV1/FVC, PEFR (or any other PFT
parameter). If an employees results are 120% of predicted and lower limits of
normal are around 70% of predicted, the user would not find problems with that
employee’s PFT for several years, unless you were doing a historical trend
analysis. To do this, one would have to pull the charts and manually trend
the data. We do this for you without having to pull the records. All the
user does is to select our trend report, and immediately it gives you the
historical trend.
8. The OHD Spirometer has a fully customizable report format. This
allows the user to customize their reports if desired. Reports and their
contents, automated interpretation, predicted values, and graphics format as
well as sizes are easily customized. It is very easy to use.
9. The OHD Spirometer is Windows based and also net-workable in Windows NT.
This will allow the user to store all previous tests for an employee, as well as
calibration records. Often, on stand alone spirometers the user cannot
save past tests, past calibration records, or even demographic data on the
employee. For many systems, each time a person is tested the demographic
data has to be re-keyed, which takes extra time. All previous tests and
calibration records are easily accessed for viewing and/or printing.
10. The OHD Spirometer has direct dial-up connectivity, which allows
multiple offices to share patient data files. If your medical department
needed to review the spirogram from another site, this feature might be
valuable. Most other Spirometers do not offer this feature.
