Flow IV

Inhaled anaesthetic gases remain the dominant method in operating rooms worldwide, yet they account for up to 63% of the total carbon footprint of a surgical procedure. An alternative already exists, total intravenous anaesthesia, in which all medications are delivered directly into the bloodstream rather than inhaled as gas. This approach produces up to 20 times fewer greenhouse gas emissions per case and offers patients faster recovery with fewer side effects. Despite these advantages, no dedicated machine has ever been built around this method. Today, doctors assemble their setups from multiple separate devices, creating fragmented and cognitively demanding workstations that contribute to a burnout rate of up to 40% across the profession. Flow IV addresses this gap by placing total intravenous anaesthesia at the centre of a single integrated machine. It features specially designed infusion pumps that connect directly to the medication bottle, eliminating the need for plastic syringes and significantly reducing the plastic waste generated per procedure. Up to six of these pumps are consolidated into one coherent unit, resulting in a cleaner, calmer, and more considered operating room for both patients and clinical staff.
