What Cidelec does

CIDELEC (legal entity: CONTROLE INSTRUMENTATION ET DIAGNOSTIC ELECTRONIQUES - CIDELEC, SAS) is a privately held French medical device manufacturer founded in 1987 as a spin-off from Angers University Hospital's Sleep Centre and the ESEO research laboratory. The company specializes exclusively in sleep-disordered breathing diagnostics, designing, manufacturing, and assembling its entire product portfolio at its headquarters in Sainte-Gemmes-sur-Loire, France. It sells portable respiratory polygraphs (Hypnea 3, CID-LX, CID-LXa), portable polysomnographs (Hypnea 2, CID-LXe), a complete sleep laboratory system (Smart-PSG), proprietary analysis software, and recurring consumable kits (BOX50E, BOX50X) to French healthcare professionals — primarily sleep specialists, pulmonologists, cardiologists, general practitioners, and hospital sleep laboratories.

The company's differentiation rests on three proprietary technology pillars: (1) PneaVoX®, a patented tracheal sound sensor that captures breathing, respiratory effort (distinguishing obstructive, central, and mixed apneas), and snoring from a single non-invasive neck sensor; (2) HypnoLighT, a single-channel EEG algorithm that automatically distinguishes sleep from wakefulness to enable AHI calculation on actual sleep time (classified correctly in >90% of periods); and (3) Hypoxic Burden, the first commercially integrated cardiovascular risk biomarker for OSAHS patients, validated in peer-reviewed cohorts from CHU Angers. Wireless add-ons (PR05 pneumotachograph, wireless EMG module, AH02 docking station) extend the platform into therapy monitoring under CPAP/BiPAP/NIV devices.

CIDELEC operates a hybrid go-to-market combining a network of regional Product Engineers providing installation, training, and field support across France with a direct-to-consumer e-commerce storefront (CIDELEC Store). Revenue is generated primarily through quote-based hardware sales bundled with 5-year maintenance (CIDELEC Care), recurring consumable revenue per recording (€6.60-€10.80), rentals, pre-reading services, and professional training programs. More than 80% of revenue is generated domestically in France, and the company has no disclosed external funding or institutional investor involvement.

• Prof. Frédéric Gagnadoux / CHU AngerscoreStrategic or Co-development PartnerProfessor Frédéric Gagnadoux, Head of Pneumology at Angers University Hospital and former President of the French Society for Sleep Research and Medicine (SFRMS), led clinical research that validated the hypoxic burden index using CIDELEC tools. A cohort of French patients from Pays de la Loire region was used in studies published in the European Respiratory Journal (2020) and American Journal of Respiratory and Critical Care Medicine (2021).
• Prof. Thomas Penzel (Charité Berlin)coreStrategic or Co-development PartnerProfessor Thomas Penzel (Doctor of Sleep Medicine, Charité Berlin) co-authored the 2017 article 'The use of tracheal sounds for the diagnosis of sleep apnoea' with Mr. AbdelKebir Sabil PhD, a researcher at CIDELEC. The article was published in Breathe journal (July 2017) and validated the use of tracheal sounds (PneaVoX® technology) for sleep apnea diagnosis.
• École Supérieure d'Électronique de l'Ouest (ESEO)coreStrategic or Co-development PartnerESEO's research laboratory, headed by Jean Pinguet, collaborated with Professor Jean-Louis Racineux at the Angers University Hospital Sleep Centre to develop the system for listening to patients' breathing during sleep. This collaboration led to the founding of CIDELEC in 1987 and the patent application for the PneaVoX® sound transducer.
• Institut de Recherche en Santé Respiratoire des Pays de la Loire (IRSRPL)minorStrategic or Co-development PartnerThe IRSRPL established and manages the patient cohort from Pays de la Loire used in studies measuring the association of hypoxic burden with stroke incidence in patients investigated for suspected sleep apnea syndrome. Several CHU Angers physicians involved in the CIDELEC research are members of this institute.

Expansion highlights6 records

Broad incumbents

• ResMed: Global leader in sleep-disordered breathing and respiratory care, offering CPAP, ventilation, and sleep diagnostics (Nocturnal Airway Coupling and cloud platforms). Competes with CIDELEC in polygraphy and home sleep testing, but sleep diagnostics is one of several large business lines.
• Philips Respironics: Named explicitly by CIDELEC as a competitor. Philips' Alice PSG and related devices directly compete with CIDELEC's polysomnography and polygraphy products, but Philips operates a much broader respiratory and hospital portfolio.
• Löwenstein Medical: German respiratory and sleep diagnostics company offering polygraphy, PSG, CPAP, and ventilation solutions. Competes with CIDELEC in polygraphy across German-speaking and broader European markets as part of a wider respiratory portfolio.
• Natus Neurology: Provider of neurodiagnostic and sleep diagnostic equipment (Embla, Xltek, Grass) for clinical and research applications. Overlaps with CIDELEC's polysomnography positioning as part of a broader neuro/sleep platform.

Direct peers

• Compumedics: Australia-based specialist in sleep diagnostics, neurodiagnostics, and ultrasound, offering PSG and HSAT hardware (Somté, Siesta, Grael). Most direct comparable to CIDELEC as a pure-play sleep/neuro diagnostics manufacturer of similar size.
• Nox Medical: Iceland-based specialist in sleep diagnostics hardware and software (Nox A1 PSG system, Nox T3 HSAT). Closely comparable niche player targeting sleep labs and HSAT with similar go-to-market and product focus.
• SOMNOmedics: German manufacturer of polysomnography and home sleep testing devices (SOMNOwatch, SOMNOscreen). Direct peer in European sleep diagnostics with comparable technology positioning and clinical-research orientation.
• Itamar Medical: Israeli specialist in sleep apnea diagnostics with the WatchPAT home sleep apnea test, acquired by ZOLL Medical. Competes with CIDELEC's HSAT positioning using a peripheral arterial tone-based technology platform.

Emerging players

• BMC Medical: Chinese respiratory and sleep company offering CPAP, ventilation, and increasingly HSAT/polygraphy devices. Emerging global competitor in the home sleep testing category, particularly in price-sensitive markets.
• Cleveland Medical Devices (CleveMed): US-based developer of portable sleep diagnostics and wireless physiological monitors (SleepView, Sapphire). Comparable niche HSAT peer targeting home-based sleep apnea screening with similar size and product focus.
