Too few labs
Accredited in-lab polysomnography facilities are concentrated in a small number of major cities. For patients in secondary cities or rural settings, the nearest sleep laboratory may be hundreds of kilometres away.
PPG sleep diagnostics · Nigeria
Sleep diagnosis that
travels to your patient.
A ring oximeter worn at home. Cloud models that estimate ODI, apnea–hypopnea burden, and sleep stages overnight. A licensed physician who reads and signs every study. Designed for Africa.

The problem
Most sleep apnea in Nigeria
is never diagnosed.
Obstructive sleep apnea and related disorders carry serious cardiovascular and metabolic risk. Yet for most patients across Nigeria, a formal diagnosis remains out of reach — not for lack of disease, but for lack of access.
Long waits
Where labs do exist, waiting lists stretch for months. Patients who need urgent evaluation — due to comorbid hypertension, diabetes, or atrial fibrillation — often receive no sleep workup at all.
Out of reach
In-lab studies are expensive and disruptive — an overnight admission, electrode placements, and travel costs combine to make diagnosis impractical for most patients, regardless of clinical need.
How it works
Three steps from prescription to report.
The entire study happens at the patient's home. The physician receives a signed, structured sleep report — no in-lab admission required.
-
01 · Wear
Wear
The patient fits a ring oximeter at home before bed. The device records SpO₂, pulse rate, and motion continuously across a full night's sleep — no wires, no clinic visit, no technician required.

02 · Analyse
Analyse
Raw PPG signal is uploaded to the Kuranyx cloud. On-device and cloud-side models estimate oxygen desaturation index (ODI), apnea–hypopnea burden, and sleep-stage architecture from the recorded waveform.

03 · Interpret
Interpret
A licensed sleep physician reviews the full signal and model output via the Sleep AeroCare platform. They sign and return a structured clinical report — typically within one to two business days.
Built for our patients
Designed for African patients — from the ground up.
Most PPG sleep devices are validated on homogeneous, light-skinned populations. Kuranyx treats African patient phenotypes as the primary design constraint, not an afterthought.
Skin-tone-aware by design
Signal accuracy across Fitzpatrick IV–VI skin phototypes is a gating requirement in validation — not a post-hoc subgroup. Models are fine-tuned on African polysomnography data collected at local sites.
Data stays home
Patient data is held resident in Nigeria in accordance with the Nigeria Data Protection Act (NDPA) 2023. No patient records are transferred to offshore infrastructure.
Trained on local sleep
Reference polysomnography data for model training and validation is sourced from Nigerian and African patient cohorts — capturing real-world comorbidity patterns relevant to the population we serve.

Evidence & status
Where we are. Transparently.
Kuranyx is in active clinical development. We state our status accurately — work in progress is framed as work in progress.
Clinical validation
An n = 150 prospective study comparing ring PPG against Type 1 polysomnography is underway. Primary endpoints: Bland–Altman agreement for ODI and AHI, with a pre-specified Fitzpatrick IV–VI subgroup analysis. Results have not yet been published or submitted.
NAFDAC regulatory pathway
A SaMD technical file has been prepared under an IMDRF risk-classification framework. NAFDAC registration is in progress. Kuranyx does not hold regulatory clearance or approval at this time.
Data protection
Patient data is held resident in Nigeria with role-based access controls and audit logging, in line with the Nigeria Data Protection Act (NDPA) 2023. No patient records are transferred to offshore infrastructure.
Investigational notice: Kuranyx is a clinical decision-support tool
undergoing validation. It supports, and does not replace, clinical judgement or
an in-lab polysomnogram where one is indicated.
