Aims & Objectives:
Technology for wireless monitoring of physiology is available. Adult studies reported data transmission below 40% of intended monitoring time (IMT).
We have conducted the first wireless study in children, the Real-time Adaptive Predicitve Indicator of Deterioration (RAPID) study to
- assess feasibility of wireless monitoring system in ward environment
- develop and test smart alarm algorithms for the detection of deteriorations
Aim: to assess transmission of wireless physiologic data in the recruits of the RAPID study.
The study was approved by REC and parental consent was gained. We have collected data on patients admitted to two paediatric cardiology wards in a specialist children’s hospital.
Heart rate (HR) and respiratory rate was measured by a wireless single channel ECG device (Isansys LifeTouch), SpO2 by a wireless pulse-oximeter (Nonin WristOx2). Recruits were allowed to run multiple sessions during their enrollment (during a single hospital admission).
Monitoring sessions were analised per recruitment for connectivity and data transmission. We defined data transmission as readings on HR between 45–250/min for LifeTouch and SpO2 60–100% for WristOx.
Acceptable data transmission was considered >60% of IMT (valid session running during ward admission).
We have collected 5 631 687 minutes of IMT from 1240 recruits. Data transmission was achieved in 81.9% for LifeTouch and 53.7% for WristOx2.
Wireless monitoring can be a reliable alternative for standard monitoring in a ward environment. Further analises required to assess validity and spread of transmitted data and to establish costs and economic impact. SpO2 transmission rates need to improve.
