Forced inspiratory flow: (Specific measurement of the forced inspiratory curve is denoted by nomenclature analogous to that for the forced expiratory curve. For example, maximum inspiratory flow is denoted FIF max. Unless otherwise specified, volume qualifiers indicate the volume inspired from RV at the point of measurement.) PEF

The peak expiratory flow (PEF), also called peak expiratory flow rate (PEFR) and peak flow measurement, [1] is a person's maximum speed of expiration, as measured with a peak flow meter, a small, hand-held device used to monitor a person's ability to breathe out air.
A wheeze is a clinical symptom of a continuous, coarse, whistling sound produced in the respiratory airways during breathing. [1] For wheezes to occur, part of the respiratory tree must be narrowed or obstructed (for example narrowing of the lower respiratory tract in an asthmatic attack), or airflow velocity within the respiratory tree must be heightened.
Sniff nasal inspiratory pressure (SNIP) refers to short, sharp voluntary inspiratory maneuver (inhalation) through one or both un-occluded (not closed or obstructed) nostrils. The tests are performed at FRC (functional residual capacity), at the end of tidal expiration. The measurement recorded is the peak pressure.
The abbreviation is not always a short form of the word used in the clue. For example: "Knight" for N (the symbol used in chess notation) Taking this one stage further, the clue word can hint at the word or words to be abbreviated rather than giving the word itself. For example: "About" for C or CA (for "circa"), or RE.
