Polysomnography + CPAP titration
An overnight, lab-based sleep study diagnosing sleep-disordered breathing, with CPAP titration where obstructive sleep apnoea is identified.
What it is & how it works
Polysomnography is an overnight, lab-based sleep study that records brain activity, breathing, oxygen levels, heart rate, and muscle movement to diagnose sleep-disordered breathing and other sleep disorders; where obstructive sleep apnoea is identified, CPAP titration is performed to determine the air pressure needed to keep the airway open during sleep.
How it's done
Typically administered as an overnight stay in a sleep laboratory, with electrodes and sensors applied by a sleep technologist before sleep and continuously monitored through the night; if apnoea is confirmed, a CPAP or BiPAP mask is fitted during the same or a follow-up overnight study and pressure is adjusted incrementally by the technologist until breathing normalises.
Conditions it treats
Why Brain Bridge
Used within Brain Bridge's structured sleep-assessment pathway, ordered only where clinically indicated rather than as a routine step for every patient reporting sleep difficulty.
Evidence & safety
Diagnostic gold standard for sleep-disordered breathing.

No. Polysomnography is non-invasive — sensors are attached to the scalp and skin with adhesive or paste, which can cause mild, temporary irritation on removal, but nothing painful is involved.
This is common and usually doesn't affect the results — a full night of normal sleep isn't required to obtain a diagnostically useful study.
