Wheezing

Wheezing in Apple Health records a reported breathing symptom and its severity. It is not an acoustic recording, an airflow measurement or an automatic asthma diagnosis.

Apple uses HKCategoryValueSeverity for this type. Unspecified is not the same as notPresent, and a missing record is neither. The integers identify labels; numerical averages and physiological reference ranges do not apply.

Peak Expiratory Flow Rate and Forced Expiratory Volume (FEV1) are separate measurements. Their values cannot be inferred from mild, moderate or severe wheezing labels. Inhaler Usage is also a separate record and does not by itself show why an inhaler was used.

These histories can support a discussion with a clinician when both have been recorded. They should retain their own times, sources and units rather than being collapsed into a symptom score.

It can be, when the user actually reports that context. NHS asthma guidance describes symptoms that may be triggered by exercise or occur at night; wheezing alone still does not establish asthma. A note saying wheezing began during a run or woke the user gives more specific context than a record that merely overlaps a workout or sleep interval.

A saved category sample is not continuous respiratory monitoring. For severe wheezing or substantial breathing difficulty, seek urgent medical help. Use an existing clinician-provided action plan where applicable; the category code cannot determine an inhaler dose.

This is a logged symptom, with no fixed sensor sampling schedule. Start-to-start gaps describe when observations were saved. A sample’s start and end times describe the interval supplied by its source; their difference does not establish the full duration of a clinical episode. Repeated or overlapping records need review before counting episodes.

This category is not currently listed in the PulsHealth sync catalog. No observations were present in the reviewed user data, so recorded severity frequencies, source differences and logging intervals could not be measured. That database coverage does not establish whether entries exist in Apple Health.
