PCRS Test – A Structured, Comprehensive, and Accessible Screening for Cardiorespiratory Sleep Disorders The cardiorespiratory sleep polygraphy (PCRS) test is a noninvasive, overnight test performed at home, which includes a 30- to 45-minute consultation with a qualified professional. Offered once in a lifetime at no cost, it provides simplified access to a diagnosis that could be critical to one’s health.
Designed to detect various conditions that are often asymptomatic during the day, this test stands out for its ability to record an electrocardiogram (ECG)—a feature missing from most devices on the market—which has, on several occasions, helped identify significant cardiac conditions.
The test includes:
Electrocardiogram (ECG): Detection of arrhythmias.
Nasal and Oral Flow: Analysis of Obstructive or Central Apneas.
Induction plethysmography: assessment of respiratory effort.
Nocturnal pulse oximetry: measurement of oxygenation and detection of desaturation.
There are two options available:
Preliminary Evaluation (Without a Prescription)
Diagnostic evaluation with a doctor’s referral
Benefits for healthcare professionals:
✔ Early detection of underdiagnosed disorders
✔ Accurate data to support your clinical decisions
