SCENARIO
You have just graduated with your BME degree and have been hired by a start-up company called “Suntronic”. They are developing a new body temperature and heart rate monitor for smart phones and want to check out the competition. The latest such device is from Spree Sports (www.spreesports.com) and they claim the device can accurately measure body temperature and heart rate. Your assignment is to assess how valid the device is as well as to identify any design flaws by comparing the temperature and heart rate readings on the device to those of an oral thermometer and pulse oximeter.
ASSIGNMENT
1. Using the provided data and supplied how to videos, calculate the mean and standard deviation for both sensor, oral thermometer and pulse ox.
Oral Thermometer Mean: 96.64716049
Spree Mean: 95.53086
Oral Thermometer Standard Deviation: 1.2922602071
Spree Standard Deviation: 0.8730378
Pulse Ox Mean: 98.08977
Spree Mean: 98.9538
Pulse Ox Standard Deviation: 23.03054
Spree: Standard Deviation: 24.87754
2.Calculate the correlation coefficient (Pearson’s r) between 1) the oral thermometer and Spree Band and 2) the pulse ox and the Spree Band.
Oral thermometer & Spree Band: 0.192798089
Pulse ox & Spree Band: 0.690806
3. Run statistical analysis to compare the 1) oral thermometer and Spree Band and 2) the pulse ox and the Spree Band.
Oral thermometer & Spree Band: 1.092798089E-21
Pulse ox & Spree Band: 0.427116
4. Graph all your results and include stars showing significance (if appropriate).
5. Write a summary of your results including any conclusions you have made from your analysis.
Our results showed that there was a positive correlation between the Pulse ox and the spree for measuring heart rate. Our results also showed that there really wasn't a correlation at all between an oral thermometer and the spree. The error bars were consistent throughout both graphs. Based on the results the spree is reliable for heart rate monitoring, but not very, but still reliable for temperature. This means that the product would overall be reliable for use.
6.Design an experiment to test your own prototype. Provide rationale for design.
To test our prototype, we will take 20 different samples, 10 of them wearing the gold standard, 10 of them wearing our prototype. We will have them sit down and rest, and gather their resting blood pressure every 5 minutes for an hour. Then, we will have our subjects walk around while also taking their blood pressure every 5 minutes for an hour. After, we will have them return to a resting stage and gather their final blood pressure every 5 minutes for an hour. We will gather the data and compare them appropriately.
