PAP Download Interpretation

and Case-Based DiscussionLoretta Colvin, APRN-BC

Nurse Practitioner

Clayton Sleep Institute

Objectives

• Review PAP adherence report elements

• Incorporate PAP report data into clinical

assessment

• Identify PAP machine technology

variations in reporting

Conflict of Interest

• I have no conflicts of interest to disclose

Adherence Assessment

Considerations

Data Assessment • Availability

– Software (Internet access, back-up options)

– Data transfer tools (Modem, card)

• Strengths

– Augments patient story

• Weaknesses

– Relies on manufacturer development,

communication and support

– wide variation in options

Patient Assessment

• Do subjective and objective reports agree?

• If not, which do you “believe” or how do

you assess further?

Recommendation

• ALWAYS view detailed data for issues

– Patient issues

• Not improving, Not tolerating,

– Report issues

• ↑ AHI, ↑ leak, ↑ pressure

• Data “issues”

• QUESTION technology when appropriate

Direct data from

machine display

screen

Data card

download in clinic

Modem

transmitted

DME creates

download and

sends to clinic

Pros: - Back-up when

no card (ex:

older machines)

- Back-up if no

computer

available

- You control the

data

- Can bring up

any report/time

range you chose

- Can access data

from anywhere

and at anytime

- Patient does not

have to bring

equipment

- DME does

the work for

you

Cons: - Limited data

available for

review

- Requires skilled

personnel to

download

- Relies on patient

to bring

machine/card

- DME must

“assign” the

modem to your

clinic

- Potential modem

glitches and

failures

- DME controls

what data

you get

- More

paperwork

and people

involved

Data Access

Tip – update your PC Based programs to most current version

when any new machine is released (ex: AirSense)

Modems

Data “Pearls” for ResMed

• AirView (formerly Easy Care Online)– Cannot set range for historical detailed data

– Select BOTH compliance & summary for more data

– “Clock time” summary view not printable – hover mouse on screen

• AirSense– Modem: HALO (hour after last off) delay with AM appts

– Conveniently displays last night usage on machine screens

• S9– Detailed report – use card in ResScan, not modem

– SleepSeeker does not interface with clinician data view

• S8– Only stores 6 months, only downloads in ResScan

– Stores mini-card out of machine

Data “Pearls” for Respironics

• EncoreAnywhere

– DME must grant access for online script changes

– Custom “day” cut-points (helpful for shift work)

– SleepMapper requires DME to link office to patient

• System One

– Internal clock stays at noon cut-off for “day”, changes

can only be done in EncoreAnywhere report

• Respironics M-series and Legacy

– Lose card, lose data

Data “Pearls” for Fisher & Paykel

• InfoSmart web

– Change to settings screens to get custom date range

and click “generate” tab

– Reports may need to be “fit to window” for printing

• Icon

– USB easily inserts backwards in computer

– Home download allows office view w/o pt account set-up

– Screen display less user friendly

– Basic mode available for “low tech” patient screens

Case Example (cont)

Worsened Variable Leak

• Patient received replacement mask

seal for FFM, worsened variable leak

begins after seal received

• Inspect equipment

• Patient sent wrong seal, inserted it

over existing seal

AHI

• Patient

complains

machine turning

itself off

• What next?

Case #1

• “Auto off” was activated

• Machine turning itself off when not detecting airflow (leak)

• Ramping with each restart

• Events noted at low pressures

• Resolved with mask re-fit

Machine and Patient

Discrepancy ?

Modem Case Example

• DOT driver with Respironics SystemOne

• Comes in for f/u

• No data for past 3 weeks on printed report

• What happened?

Respironics DOT modem • Assess last

machine usage

• May not transmit if no usage

• If concerned about modem, “test” by allowing to run for 1 min then transmit

• When in doubt, start self-monitoring

Patient Self-Monitoring

• Patient log

• Machine data monitoring

– On screens

– Online

Humidifier

Case Example

• Patient calls complaining of nasal and

mouth dryness on CPAP 12 using full face

mask.

• Reports humidifier set at 5

• What do you do? (Group)

– Change humidifier setting

– Do not change humidifier setting

– Ask more questions

Case Example – next steps

• Determine machine brand

• Verify no significant mask leak

• Use your cheat sheet for humidifier settings range

• Max varies based on machine (5-8) and tubing

• Patient vs. algorithm adjustment ?

• Can you walk a patient through changing it?

• Role for add-on equipment? (ex: heated tubing)

• Remember “quirk” for Respironics heated tubing

Using Technology

Always Pay Attention!
