Does the Albus Home contactless bedside device accurately monitor heart rate compared to 3-lead ECG in adult volunteers?
The Albus Home contactless bedside device demonstrated 91% accuracy in monitoring heart rate compared to 3-lead ECG across various sleeping positions.
Abstract Rationale Nocturnal signs are important across cardiorespiratory conditions. For example, heart rate (HR) and breathing rate (BR) changes predict exacerbations in asthma and COPD, and elevated resting HR predicts poor outcomes in heart failure, including mortality. However, continuous yet accurate monitoring at home remains a challenge: Existing tools (such as home polygraphy and ECG) are burdensome and unsuitable to use beyond a few nights; Emerging wearable tools may cause discomfort while sleeping and rely on daily adherence (e.g. charging) by patients. Albus Home is a contactless and automated bedside device that monitors multiple nocturnal signs without patients needing to do or wear anything. Strong performance in monitoring breathing rate and cough was previously reported (PMID: 36236241, 36478916). The aim of this proof of concept study was to evaluate the accuracy of HR monitoring by Albus Home compared against 3-lead Electrocardiogram (ECG/EKG) in various sleeping positions, and with and without a duvet. Methods Adult volunteers were monitored during a brief sleep period using Albus Home and wearing FDA-approved polygraphy with 3-lead ECG (Somnotouch RESP, Somnomedics EU). HR readings were compared for each minute between Albus Home and the reference. Accuracy was defined as % of Albus readings within ±10% or ± 5 beats/min (whichever greater) of ECG. Results HR was monitored for 9 adult volunteers (7M:2F) for 30-90 minutes, totalling 555 minutes (average 62 minutes per participant). Participants slept in a variety of positions, with 32% of total sleep time in supine position, 22% prone, 30% on side facing device, and 16% on side facing away. 57% of monitoring duration was under a duvet. Mean accuracy across all participants was 91%. Accuracy was maintained across a broad range of low and high heart rates (from 49 to 111 beats per minute). Conclusions The contactless and automated Albus Home device shows high accuracy in monitoring HR across multiple sleeping positions and regardless of whether duvets are used. Albus Home enables long-term accurate and objective nocturnal monitoring without adding any patient burden, enabling diverse applications in cardiopulmonary clinical trials and clinical care.

Ozcan et al. (Fri,) reported a observational. Albus Home bedside device vs. 3-lead Electrocardiogram (ECG/EKG) was evaluated on Accuracy (% of Albus readings within ±10% or ± 5 beats/min of ECG). The contactless Albus Home bedside device demonstrated a mean accuracy of 91% for heart rate monitoring compared to 3-lead ECG across various sleeping positions.
