Patient Posture-Adaptive Non-Contact Respiratory Rate Measurement Inside a Moving Ambulance Using RGB and Thermal Cameras
Diagnostics · 2026-10-08 · Added 13 October 2026
Japanese researchers built a contact-free respiratory-rate monitor using RGB and thermal cameras that worked inside a moving ambulance, with errors of 0.59–4.38 breaths/min depending on posture and respiratory pattern.
- Study type
- Simulation
- Design
- Simulation / technical validation study
- Participants
- Simulated respiratory conditions in a moving ambulance, multiple postures
- Main finding
- Mean absolute error 0.95/0.59/2.80 breaths/min for bradypnoea/normal/tachypnoea supine and 1.08/1.90/4.38 semi-sitting; image registration error within 1 pixel
- Caveat
- Simulated subjects and conditions only — no real patients, and accuracy degraded most for tachypnoea in semi-sitting positions
- Bottom line
- Hypothesis-generating
Why it matters in Australia (Medium relevance). Continuous vital-signs monitoring is universal Australian practice; this is engineering-stage work, not something any ambulance service has adopted yet.
Learning goal
Weigh the reliability of contact-free camera-based respiratory rate monitoring for patients in different postures during transport.

HFNO reduces intubation vs conventional oxygen
Systematic review and meta-analysis of 17 RCTs (1,955 patients) comparing high-flow nasal oxygen with conventional oxygen and NIV for acute respiratory failure in the ED — HFNO reduced intubation versus conventional oxygen (RR 0.61) but not versus NIV, with no clear benefit over either in COPD or acute heart failure.

One dose dexamethasone enough for paediatric asthma
Nearly two-thirds of children with asthma exacerbations were treated with 2 doses of dexamethasone rather than a single dose, even though treatment with 2 doses was not associated with improved outcomes.
