FAQs about RMS Helios 401 Spirometer (PFT)

What is the RMS Helios 401 Spirometer used for?

It’s a diagnostic device used for Pulmonary Function Tests (PFTs) to measure lung capacity and airflow, helping identify conditions such as asthma, COPD, and other respiratory disorders.

Is the Helios 401 portable?

Yes, it’s lightweight and USB-powered, making it convenient for bedside and camp-based use.

What parameters can the Helios 401 measure?

It measures FVC, FEV1, FEV1/FVC ratio, PEF, MVV, and several other spirometric values critical for pulmonary assessment.

Does it require calibration?

It can be calibrated by inbuild functionality.

Can it connect to a computer?

Absolutely. The Helios 401 connects via USB and is compatible with RMS PFT software on Windows 10/11 PCs.

Can reports be printed or exported?

Yes. Reports can be saved, exported, or printed directly from the software in formats like PDF or CSV.

Who can use the RMS Helios 401?

Ideal for hospitals, clinics, diagnostic centers, and pulmonologists performing routine PFTs.

What warranty does it include?

The RMS Helios 401 comes with a 1-year manufacturer warranty covering defects in materials or workmanship.

  • Below are the advantages of PC bases spirometers:
    PC spirometers, also known as computer-based spirometers, offer several advantages over traditional handheld spirometers: 1. Accurate and precise measurements: PC spirometers use sophisticated algorithms to ensure accurate and precise measurements of lung function parameters such as forced vital capacity (FVC) and forced expiratory volume in one second (FEV1). These measurements are crucial for diagnosing and monitoring lung diseases such as asthma and chronic obstructive pulmonary disease (COPD). 2. Real-time data visualization: PC spirometers can display real-time data visualization of spirometry results, allowing clinicians to assess the quality and consistency of the measurements and make immediate treatment decisions. 3. Easy to use: PC spirometers are user-friendly and require minimal training. Patients can easily perform the spirometry tests at home or in the clinic, and the results can be quickly transferred to the clinician for review. 4. Data storage and analysis: PC spirometers can store and analyze large amounts of spirometry data, allowing clinicians to track changes in lung function over time and make informed treatment decisions. 5. Integration with electronic medical records (EMRs): PC spirometers can be integrated with EMRs, enabling clinicians to quickly access and share spirometry data with other healthcare providers and improve patient care coordination.

Our pick for buyers who prefer this reporting format: Clarity SpiroTech. Its grouped report, explicit FEV6/FVC and FEV1/FEV6 fields, and additional MVV timing rows make it worth shortlisting when those details matter to your workflow. Ask for a current demonstration with those fields populated before ordering. Helios remains a strong alternative when FIF25/50/75 or an explicit IC row is important.

Which parameters appear in this sample report?

The table above lists the report fields by test group, including volume, flow, timing and calculated results. Blank cells in the PDF do not demonstrate a completed result.

Does the computer come with the spirometer?

This is a PC-based device. Confirm the supplied package and software requirements with RespBuy; do not assume a laptop is included.

Can I compare this sample with the other model’s sample to judge accuracy?

No. The reports concern different people, test dates and prediction equations. Their numeric results cannot establish which device is more accurate.

What should I confirm before ordering?

Confirm the current software version, required parameters, compatible computer, consumables, installation support and warranty coverage with RespBuy.
