What does an inhaler usage count mean?
HealthKit's Inhaler Usage type records the number of puffs taken from an inhaler. It is cumulative count data: a record can represent one puff or several. The quantity alone does not identify the medicine, its strength, an inhaled dose in milligrams, or whether technique was effective.
Can puff counts distinguish reliever and controller treatment?
Only with separate, reliable medication context. A total count cannot tell whether use was scheduled, symptom-driven or part of an agreed plan before exercise. It also cannot establish adherence without the prescribed schedule and complete logging coverage. NHLBI's asthma guidance centers these decisions on an individual action plan.
| Recorded information | What it does not establish |
|---|---|
| Puff count | Drug name, strength or amount reaching the lungs |
| Sample timestamp | That a late or imported log was saved at the moment of use |
| Daily total | Treatment adherence or asthma control by itself |
| No records | No medication use |
How should daily totals and logging gaps be read?
Sum compatible, nonduplicated count contributions for the reporting day after reviewing sources. An app can save one record per event or a summary, so the number of rows is different from the number of puffs. Overlapping manual and imported logs can inflate totals; a change in logging app can change coverage.
There is no universal normal daily puff count across medicines and treatment plans. Compare recorded use with the actual prescription and known coverage rather than applying a generic threshold or changing treatment from the graph alone.
What other information makes the log useful?
An identified medicine, prescribed schedule, symptoms and peak flow readings can make a review more informative. Their timing can describe context, but it does not prove a trigger or medication response. Follow the agreed action plan when symptoms worsen; the count record is not a replacement for it.
Does PulsHealth currently collect this type?
This HealthKit type is not listed in the current PulsHealth sync catalog. Its presence in this reference does not promise collection. Database absence does not establish absence in Apple Health.
Understanding your records
Recording frequency, source and coverage affect what you can conclude from this data. Read the recording guide.
- One record
- Cumulative recorded puff count; event or summary shape depends on the writing app.
- Frequency
- Source-specific puff logging and import cadence; record counts can differ from puff-event counts when entries summarize multiple puffs.
- Context
- Use documented medication identity and source-specific event or summary semantics; a puff count alone does not establish dose, technique or treatment response.
- Coverage and gaps
- No observations in the reviewed database window; this does not establish absence in Apple Health or normal physiology.
- Summaries
- Sum compatible, nonduplicated puff counts; do not infer dose or adherence.
- Metadata
- No sample metadata available to inspect. Raw puff counts cannot establish medication identity or inhalation technique.
