Thick film flow sensor for respirator applications

A new approach to monitoring respiration activity for first responders is proposed. This approach emphasizes low cost and portability. Current commercial methods cost upwards of $100 and aren´t reusable or portable. The design goal was to achieve a portable stand alone unit that measures and displays both breaths per minute as well as inhalation/exhalation using simple low cost commercial components. The prototype device is portable and battery operated as well as accurate. This approach has benefits in the field for emergency medical technicians as well as other medical professionals.
