Could contactless technology help monitor patients in busy ED waiting rooms? 📷
New EMF-funded research from Townsville University Hospital has explored whether camera-based technology could reliably measure vital signs after triage, with the potential to support patient monitoring while people wait for care.
The pilot study recruited 300 adult walk-in patients and compared contactless measurements of blood pressure, heart rate, respiratory rate, oxygen saturation and temperature with standard monitoring.
🔎 The study found:
🔹 Camera-based monitoring showed good overall accuracy compared with standard measurements
🔹 Respiratory rate, oxygen saturation and temperature showed the closest agreement
🔹 Blood pressure and heart rate showed greater variability, indicating further refinement is needed before clinical use
🔹 Patient acceptability was high, with 79% rating the contactless monitoring process positively
The findings highlight the potential of contactless monitoring in emergency care, while showing that further refinement and research are needed before the technology is ready for clinical practice.
The study was led by Courtney West, with Dr Vinay Gangathimmaiah and colleagues.
