The single-use SFM3304-D gas flow sensor is designed to be used in close proximity to patients. It accurately monitors both inspiratory and expiratory flows up to ±250slm with a bidirectional measurement and has an integrated heater that prevents condensation, allowing it to function in extremely humid conditions. It is robust and cost-effective and can easily be connected to respiratory breathing tubes due to its medical cones and clip-on electrical connection, while adding minimal dead space (<10mL). The SFM3304-D is individually packaged for protection and ease of use. The label on the individual packaging can be customized upon request, while a standard version is available for distribution.
