Stowood

Since 1992 Stowood have been developing solutions to simplify the process of screening and diagnose sleep and breathing related disorders, developing or sourcing products suitable for both hospital and home use.

Based in Oxford, UK, Stowood combines engineering precision with clinical insight to advance sleep diagnostics. We design and manufacture our own Black series multi-channel recorders, and supply high-quality oximetry, polygraphy and polysomnography systems from trusted global partners.
Our latest Visi-Download 2 software with hypoxic-burden analysis delivers powerful insights for clinicians. Together, our hardware and software form a complete, reliable suite for hospitals, sleep laboratories, and home-testing services.

Sleep Apnoea and Related Breathing Disorders

This group encompasses disorders characterised by abnormal respiration during sleep. Sleep Apnoea subtypes (obstructive, central, mixed, and complex) are defined by distinct pathophysiological mechanisms but share common features of recurrent apnoea/hypopnoea events, oxygen desaturation, and sleep fragmentation. Related conditions - including snoring, upper airway resistance syndrome, nocturnal hypoxaemia, sleep-related hypoventilation, and obesity hypoventilation syndrome - may present independently or in conjunction with apnoea. Accurate characterisation using PSG, oximetry, and CO₂ monitoring is critical, as diagnostic differentiation determines therapeutic approach.

Sleep-Related Movement Disorders

This category includes conditions associated with repetitive or sustained muscle activity during sleep. Periodic limb movements, restless legs syndrome, and sleep bruxism are identified by characteristic EMG activity and may contribute to arousals, sleep fragmentation, and daytime impairment. Diagnosis relies on PSG with targeted EMG channels to differentiate pathological movements from benign variants.

Central Disorders of Hypersomnolence

These disorders are characterised by excessive daytime sleepiness not explained by disturbed nocturnal sleep or misaligned circadian rhythm. They include narcolepsy, idiopathic hypersomnia, and related presentations. The Multiple Sleep Latency Test (MSLT) and Maintenance of Wakefulness Test (MWT), performed following PSG, are gold-standard tools to quantify sleep latency and assess for pathological REM sleep onset. Precise testing protocols are essential for differential diagnosis and management.

Parasomnias

Parasomnias are undesirable physical events or behaviours arising during sleep, typically from REM or NREM stages. REM sleep behaviour disorder involves loss of REM atonia and dream enactment, while nocturnal epilepsy produces stereotyped seizure activity that can mimic parasomnias. Video-PSG is the reference standard for capturing and differentiating these conditions, with significant implications for safety and neurological assessment.

Insomnia & Circadian Rhythm Disorders

These disorders involve difficulty initiating or maintaining sleep, or misalignment between the endogenous circadian system and environmental or social demands. Chronic insomnia is primarily a clinical diagnosis, but PSG may be used to exclude comorbid sleep pathology. Circadian rhythm sleep-wake disorders, including delayed sleep phase and shift-work disorder, are evaluated using actigraphy, sleep diaries, and in some cases PSG, to confirm phase shifts or rule out overlapping sleep disorders.
