Hamilton-HF90
Advanced high flow oxygen therapy.
The Hamilton HF90 was developed to deliver high-flow oxygen therapy in a compact, intuitive system tailored for modern clinical environments. RKS Design partnered with Hamilton Medical to translate complex respiratory technology into a clear, approachable user experience—balancing performance, ergonomics, and visual simplicity. Guided by Psycho-Aesthetics®, the HF90’s form, interface, and interaction design reduce cognitive load for clinicians while supporting accurate, efficient care delivery across acute and non-acute settings.
Precision ventilation designed for clinical clarity and confidence.
