Abstract

BACKGROUND

As Japan is the world's fastest-aging society with a declining population, it is challenging to secure human resources for care providers. Therefore, the Japanese government is promoting digital transformation and the use of nursing care equipment, including nonwearable devices that monitor heart and respiratory rates. However, the feasibility of monitoring heart and respiratory rates with nonwearable devices and the consistency of the rates measured have not been reported.

OBJECTIVE

In this study, we focused on a sheet-type nonwearable device (Safety Sheep Sensor) introduced in many nursing homes. We evaluated the feasibility of monitoring heart rate (HR) and respiratory rate (RR) continuously using nonwearable devices and the consistency of the HR and RR measured.

METHODS

A sheet-type nonwearable device that measured HR and RR every minute through body vibrations was placed under the mattress of each participant. The participants in study 1 were healthy individuals aged 20-60 years (n=21), while those in study 2 were older adults living in multidwelling houses and required nursing care (n=20). The HR was measured using standard methods by the nurse and using the wearable device (Silmee Bar-type Lite sensor), and RR was measured by the nurse. The primary outcome was the mean difference in HR and RR between nonwearable devices and standard methods.

RESULTS

The mean difference in HR was -0.32 (SD 3.12) in study 1 and 0.04 (SD: 3.98) in study 2; both the differences were within the predefined accepted discrepancies (<5 beats/min). The mean difference in RR was -0.98 (SD 3.01) in study 1 and -0.49 (SD 2.40) in study 2; both the differences were within the predefined accepted discrepancies (3 breaths/min).

CONCLUSIONS

HR and RR measurements obtained using the nonwearable devices and the standard method were similar. Continuous monitoring of vital signs using nonwearable devices can aid in the early detection of abnormal conditions in older people.

摘要

背景

日本是世界上人口老龄化速度最快的国家，人口数量不断减少，这给护理人员的人力资源保障带来了挑战。因此，日本政府正在推动数字化转型和护理设备的使用，包括可监测心率和呼吸频率的非穿戴设备。然而，目前尚未有研究报告非穿戴设备监测心率和呼吸频率的可行性以及所测数据的一致性。

目的

本研究聚焦于一种在许多养老院中使用的片状非穿戴设备（Safety Sheep Sensor），旨在评估使用非穿戴设备连续监测心率（HR）和呼吸频率（RR）的可行性以及所测 HR 和 RR 的一致性。

方法

将一种通过身体振动测量每分钟 HR 和 RR 的片状非穿戴设备放置在每位参与者的床垫下。研究 1 的参与者为年龄在 20-60 岁的健康个体（n=21），研究 2 的参与者为居住在多户住宅并需要护理的老年人（n=20）。HR 通过护士使用标准方法和可穿戴设备（Silmee Bar-type Lite 传感器）进行测量，RR 由护士测量。主要结局指标为非穿戴设备与标准方法测量的 HR 和 RR 的平均差异。

结果

研究 1 中 HR 的平均差异为-0.32（SD 3.12），研究 2 中为 0.04（SD：3.98）；这两个差异均在预定的可接受差异（<5 次/分钟）范围内。研究 1 中 RR 的平均差异为-0.98（SD 3.01），研究 2 中为-0.49（SD 2.40）；这两个差异均在预定的可接受差异（3 次/分钟）范围内。
