A sleep-study report is an important clinical document, but it is not automatically a complete shopping specification for a CPAP machine. A safer pathway separates diagnosis, treatment selection and equipment purchasing into distinct steps.
Step one: establish the diagnosis
The AASM states that diagnostic testing for obstructive sleep apnea should be performed together with a comprehensive sleep evaluation. Polysomnography is the standard diagnostic test, while technically adequate home sleep apnea testing can be used in appropriate uncomplicated adults at increased risk of moderate-to-severe OSA. Source: AASM diagnostic guideline.
If a single home test is negative, inconclusive or technically inadequate, the guideline recommends polysomnography. It also recommends polysomnography rather than HSAT for several higher-risk groups, including people with significant cardiorespiratory disease or suspected sleep-related hypoventilation.
Step two: obtain clinical interpretation
A sleep study can contain AHI or REI, oxygen data, sleep-stage information, body-position findings, event type and other measurements. Those values should be interpreted together rather than using one number as a shopping instruction.
Step three: establish the PAP plan
The treatment plan should clarify whether the required mode is fixed CPAP, APAP, bilevel PAP or another approach and identify clinically relevant settings or ranges. The AASM's PAP guideline supports CPAP and APAP for ongoing adult OSA treatment and emphasizes follow-up after treatment is initiated. Source: AASM PAP guideline.
Step four: compare compatible machines
Once the clinical requirement is established, shopping becomes much easier. Compare machines that actually support the required mode, then examine humidification, data availability, mask compatibility, consumables, warranty, service, dimensions, power requirements and price.
Step five: select and fit the mask
Mask fit can materially influence comfort and leak. A nasal-pillow, nasal or full-face interface may suit different users. Do not assume that the most expensive mask is the correct mask.
See Respmart's CPAP mask types and fitting guide and mask collection.
Step six: arrange follow-up
The buying journey should not end when the parcel arrives. The AASM guideline identifies adequate follow-up, troubleshooting and monitoring of objective efficacy and usage data as part of appropriate PAP treatment.
Frequently asked questions
Can Respmart tell me which machine I need from my AHI?
Not from AHI alone. Respmart can help compare equipment after the clinical treatment requirement has been established.
Is a home sleep test always enough?
No. AASM guidance limits HSAT to appropriate clinical circumstances and recommends polysomnography in several higher-risk situations or after an inadequate, negative or inconclusive HSAT when OSA remains a concern.
Does the sleep-study report always contain the final PAP settings?
No. Diagnostic information and treatment settings are distinct. Clarify the treatment plan with the clinician when necessary.
