The cost of and simplicity of the EFV thoechnology has garnered interest for the HVAC industry for measuring precise pressure drops through building ducts and piping. Designed originally for high fidelity turbulent measurements, the EFV technique can also provide an inexpensive method of measuring velocity around duct elbows and in tight spaces, allowing more flexibility in monitoring building diagnostics.
In America, a staggering 1.5 million medication errors occur every year, resulting in more than 7000 deaths, and costing the healthcare institutions a shocking $3.5 billion annually. Out of the life-threatening errors, 60% were associated with intravenous injections, and 41% of deaths were due to wrong dosage. Infusion pumps were invented to regulate the flow of drugs into a patient. Unfortunately, these devices were not shown to significantly decrease error rate. EFV technology can be integrated into infusion pumps to provide an accurate, reliable method to monitor real-time drug dosage and detect injection failure.
Currently, in gravity driven cases, a nurse must count the drips per minute in a drip-chamber in order to gauge the flow-rate and adjust the flow with a roller-clamp. This infusion technique was invented around the second world war and little has changed since then. The minimal size and cost of the EFV architecture enables the sensors to be used as disposable units that can be integrated into any tube set. This device can give visual feedback of the administration rate regardless of the infusion method. Think of it as bringing the drip chamber into the 21st century.
