Lung Function Monitoring
Connected Spirometer for Remote Respiratory Monitoring
Lung function declines quietly. A connected spirometer lets a COPD or asthma patient blow into a device at home and gives your pulmonology team FEV₁, FVC and peak flow trends between visits — the data that turns an exacerbation from an admission into a medication adjustment.

Overview
Why Remote Spirometer Monitoring Works
For a patient with COPD or asthma, the weeks before an exacerbation usually leave a trace. Lung function slips, peak flow drops against personal best, and reliever use climbs — often days before the patient feels sick enough to call. Almost none of that is visible to a clinic that sees the patient quarterly.
Connected spirometry makes it visible. Patients perform a guided effort at home, results transmit automatically, and your team watches FEV₁ and peak flow against that individual’s baseline. It is one of the clearest cases in remote monitoring where earlier information genuinely changes the outcome.
Spirometry is billed through RTM rather than RPM in most programs, and sits naturally inside pulmonology and CCM workflows. Every device in the HealthArc device family reports into one dashboard and one monthly billing record — not a separate portal per vendor.
Device Features
Built for Clinical Programs, Not Consumers
Connected spirometry for remote respiratory programs, tracking FEV₁, FVC and peak expiratory flow at home and supporting RTM respiratory device-supply and management codes.
FEV₁, FVC and Peak Flow
The measures respiratory clinicians actually use, captured at home and trended over time rather than reconstructed from a patient’s recollection.
Personal-Best Baselines
Results are interpreted against the patient’s own established baseline, which is the only way a home spirometry number becomes clinically meaningful.
Early Exacerbation Signals
A sustained decline against baseline triggers an alert, creating the window in which a steroid or antibiotic course can prevent an admission.
Guided Patient Effort
On-device guidance helps patients produce a usable effort without a technician present — the main practical barrier to home spirometry.
RTM-Ready Documentation
Device supply and management time are documented to support respiratory RTM billing, which is where most spirometry programs are reimbursed.
Paired With Oximetry
Most respiratory programs run spirometry alongside pulse oximetry, giving both lung function and oxygenation for the same patient in one view.
How It Works
From the Patient’s Home to Your Dashboard
Four steps, none of which require the patient to own a smartphone, install anything or report a number to anyone.
1
The device ships activated
HealthArc procures, configures and ships the spirometer directly to the patient, along with enrollment support and training. It works out of the box — there is no pairing sequence for your staff to talk anyone through.
2
The patient takes a reading
A single action at home, with no app to open and no account to sign into. That simplicity is what keeps adherence intact past the first few weeks.
3
Data transmits over cellular automatically
The reading moves to the HealthArc platform over the mobile network, encrypted and time-stamped. Nothing is transcribed by hand, so nothing is mistyped or forgotten.
4
Your team reviews, acts and bills
Readings are checked against the thresholds you set for that patient, alerts route to the care team, and monitoring days plus management time accumulate into a billing-ready monthly record.

What the device measures, how it connects, and what the patient has to do. The short answer to the last one is: take the reading.
No apps. No pairing. No Wi-Fi. Cellular connectivity is the reason HealthArc programs can enroll patients who do not own a smartphone or have home broadband — typically the highest-risk patients in the panel.

FAQ
Frequently Asked Questions
Is home spirometry billed under RPM or RTM?
Usually RTM. Remote therapeutic monitoring covers non-physiologic data including respiratory system status, and 98976 is the device-supply code for respiratory monitoring. Our RTM page explains the distinction and the management codes that go with it.
Can patients produce a reliable effort without a technician?
On-device guidance coaches the patient through the maneuver, and results are trended against that patient’s own baseline rather than against population norms — which is what makes home spirometry clinically usable. It supplements rather than replaces formal pulmonary function testing.
Which patients benefit most?
Patients with COPD or asthma who exacerbate repeatedly, patients recently discharged after a respiratory admission, and patients on therapies where response needs to be tracked between clinic visits.
Can spirometry run alongside pulse oximetry for the same patient?
Yes, and most respiratory programs do exactly that. Lung function and oxygen saturation answer different questions, and both appear in one patient view with one monthly billing record.
Does the spirometer need a smartphone or app?
No. Like the rest of the HealthArc device family it is cellular connected, so results transmit without an app, a pairing step or a home Wi-Fi network.
