In the wake of the COVID-19 pandemic, pulse oximeters, devices that measure blood oxygen saturation, have become essential tools for monitoring the health of individuals, especially those with underlying conditions. However, the surge in demand for these devices has led to supply constraints and difficulty in finding them in stock.
Embarking on a DIY Solution
Inspired by the scarcity of pulse oximeters, John Keefe, an ardent enthusiast in the field of electronic devices, set out on a mission to create his own pulse oximeters. He harnessed the power of an Uno microcontroller board, a Pulse Ox and Heart Rate sensor module from sparkfun, and an addressable Neopixel shield to construct a functional pulse ox.
The Working of the DIY Pulse Oximeters
The device ingeniously utilizes the sensor to measure pulse rate and oxygen levels from a fingertip. These measurements are then displayed on a Neopixel shield, providing a visual representation of heart and lung activity through heart and lung icons.
A Ray of Hope Amidst Uncertainty
While the DIY pulse oximeters created by John Keefe are not intended to replace professional medical devices, they provide a valuable tool for individuals to monitor their health, especially during the pandemic. The availability of the code on Github and a video on Vimeo empowers others to create their own pulse oximeters, fostering a sense of community and empowerment.
Additional Information
It is important to note that the DIY pulse oximeters are not intended for use in diagnosing or treating medical conditions. They are not approved by any medical regulatory body and should be used as a supplementary tool for monitoring purposes only. However, their ability to provide real-time insights into heart and lung activity can be invaluable in certain situations.
The Silver Lining: The COVID-19 pandemic has brought about many challenges, but it has also inspired innovation and collaboration. The creation of DIY pulse oximeters like John Keefe’s is a prime example of how individuals can contribute to solving real-world problems. It is a reminder that in times of crisis, human ingenuity and resourcefulness can shine through.
Conclusion: The DIY pulse oximeters crafted by John Keefe are a commendable initiative that addresses the pressing need for pulse oximeters during the COVID-19 pandemic. By sharing his design and knowledge, he has provided a beacon of hope and empowerment, encouraging others to take matters into their own hands. The spirit of collaboration and innovation exemplified by John Keefe is a powerful reminder of the resilience and determination of the human spirit in the face of adversity.
