Device Benefits!

Pulse Sensing Light	This alerts the patient to whether their pulse is actually being taken correctly. It also allows the patient to quickly count their own pulse by counting each blink.
Timer	The timer allows for easy monitoring of time. It allows the patient to steady their finger before they start recording their pulse and provides an amount of time that is ample enough for them to record a number that can easily be doubled to obtain a pulse. It thus saves the patient time by providing them with a convenient and accurate method of keeping track of time.
Value Output	The value output allows the patient to actually take the values generated by the IR sensor and develop a graph that charts their pulse over time in a simple program like Excel. By placing a correction in the raw values generated, the values will also generate a smoother curve making this process even easier for the patient. It also allows them to possibly update their doctors with this data in case of emergency.

The current device provides asthma patients with the benefit of being able to easily track and monitor their pulse at home, and thus overall the effects of an attack on their respiratory and circulatory systems. Unfortunately, due to an inability to test the success of the device measuring oxygen concentration, it cannot actually give the patient’s blood oxygen saturation levels. As such, this is a weakness of the product. If better technology and time had been available, it would have been invested into finding a way for the product to actually measure oxygen concentration. If the product had been able to actually monitor the concentrations, it would have proven to be a more effective product and more competitive against other pulse oximeters. Unfortunately, due to time constraints resulting from a delay caused by reverse engineering the counterfeit Nellcor sensor, it was not feasible to develop a prototype that would limit extraneous IR light interference. With more time, an actual prototype of the IR LED and sensor casing could have also been developed. This would have limited some of the error involved with the current set-up of the product.
