Summary

The Hyperventilation Provocation Test (HPTest) associated with end-tidal CO2 pressure (PETCO2) measurement is a diagnostic tool for idiopathic hyperventilation syndrome (HVS). However, interpretation of HPTest remains unclear regarding the relevant PETCO2 values to consider and the occurrence of subjective symptoms.

This case-control study aims to identify accurate HPTest measurements for the diagnosis of HVS, regardless of symptoms occurrence.

Hyperventilation Provocation Test (HPTest)

During the HPTest, the subject is comfortably seated in a chair with armrests and breathes in a mouthpiece with a salivary collector and a nasal clamp. Parameters of ventilation and gas exchange are analyzed via an Oxycon ProTM (SN808008) with TripleV-Volume Sensor digital(Jaeger). The HPTest begins with a 3-minutes adaptation phase during which the patient is asked to "breathe normally". During the 3-minutes of voluntary hyperventilation phase, the patient is asked to increase his tidal volume and support a breath rate of at least 30/min in order to reduce his PETCO2 by at least 50%. During the recovery phase of the HPTest, the patient is invited to regain a "natural breathing" for 5 minutes, without guidance on tidal volume or breath rate.
