Potential medical applications for the Honeywell Zephyr™ Airflow Sensors include: anesthesia delivery machines; sleep apnea machines; ventilators; oxygen concentrators; nebulizers, which are devices that convert liquid medication to a mist so it can be more easily inhaled into the lungs; spirometers, instruments that measure lung capacity for patients with respiratory disorders; hospital diagnostics, such as spectrometry and gas chromatography; patient monitoring, such as respiratory monitoring; and ventricular assist devices, which are mechanical pumps that assist the heart by pumping blood to the rest of the body for patients with congestive heart failure.
