Pulse oximetry has been used in medicine for some time, but since the coronavirus pandemic, the public has been starting to use them more frequently to measure their own oxygen saturation. A pulse oximeter effectively tells us how much oxygen is in our blood at any one time.

To understand how pulse oximetry works, we need to first understand how oxygen is carried around your bloodstream. Oxygen is absorbed through specialised membranes in the lungs and diffuses into your blood, however, oxygen does not simply float around in our bloodstream. …

So we’ve all heard about Apple’s new M1 chip, and Apple promised a lot with this chip. Including up to 3.5x faster CPU, as well as almost 4x faster video processing. All this while using 25% of the power of a standard mac without the M1 chip.

Why the M1 Chip is So Fast | The Dev Doctor

These are very bold claims from Apple, and the world was poised to get there hands on these chips to see how fast they really were. And now we’re getting real-world results of just how fast the M1 chip is. …

So let’s talk about the iPhone 13. Since the release of the new iPhone 12 there’s been a whole host of rumours of what we can expect for the new iPhone 13. But what is truth and what is fiction?

Today on the Dev Doctor channel we’re discussing Mindset4Dementia, an app which is transforming the diagnosis of dementia using their innovative app. It combines a slick user interface with industry-leading AI to attempt to provide an earlier diagnosis for those suffering from dementia.

Or at least that’s the theory…

But is all of this possible?

Today on the channel I’ll take a look into the app, and then go into a deep dive of its workings with the founder of Mindset4Dementia, Hamzah Selim.

Debunking the rumours of Bill Gates digitally spiking your vaccine.

The Dev Doctor — Debunking Microchipss In Vaccines

There’s a lot of misinformation going around about the coronavirus vaccines. But one that’s stood out to me is that Bill Gates wants to put microchips in the vaccine. I thought it might be a good idea to unpick this!

A recent YouGov poll suggests that 28% of Americans think that Bill Gates wants to use the coronavirus vaccine to inject microchips into people, and this rises to 44% among republicans.

But where did this come from?

The origin of this rumour appears to come from an interview Bill Gates gave in March, when he said that eventually “we will have some digital certificates” which could be used to show who’d recovered, been tested and ultimately who received a vaccine. …

The truth about building simulated healthcare.

As a medical student, I felt very disillusioned with the way we study medicine. Hours spent in the library, endless time spent in lectures, and single best answer examinations that inadequately prepared you for work as a doctor.

My answer to this — PixelDr.

PixelDr is a 2D e-simulation designed to reimagine the way we teach medicine. The idea was to try and recreate the experience of being a doctor in the emergency department in a realistic but gamified way. …


Bridging medicine and computer science

I am excited to announce my new YouTube channel — The Dev Doctor.

For some time now I have been working as a doctor and developer in an attempt to bridge these two professions and bring innovation to the healthcare space.

My team and I regularly work on exciting projects, spanning adaptive bot technology to social network design. In this channel, we will be discussing all of our projects, how we built them, and the difficulties faced along the way. We’ll also discuss how you can start your own Medtech journey, as well as the latest news from the field.

If this is something you’d be interested in, please subscribe to the channel.

And as always — Happy Devving!


How I Got Two Top Writer Tags in The Same Week

The week of the 19th of August was an exciting week for me. I started the morning as I do any other, relentlessly snoozing my alarm until the pressure of arriving for my clinic on time becomes more pressing than my need for rest. I eventually respond in the manner my alarm expects and check my emails, like every morning. I’m not sure who I expect to email me between the hours of 23:00 and 06:30, but it is a habit to which I have become accustomed.

As I worked my way through the general junk my account now attracts, I stumble across an email from Medium. While often junk in itself (sorry Medium), this email is different. This is the email I have been waiting for since my first article on Medium. …

The gaming industry has been growing at an accelerated rate for over a decade and shows no signs of slowing. A recent report from Global Data predicted the industry to hit $300 billion by the year 2025.

Industries that grow at such a rate seldom find themselves far from controversy — the gaming sector is no exception. The industry and its main players have been embroiled in several scandals in recent years, its focus on gun violence and the severe levels of burnout experienced by game designers to name a few.

While much time is devoted to discussing the damage of the industry, we rarely find a story casting a positive light on the gaming sector. …

The Future of Medical Record Keeping in Permissioned Blockchains

Despite the wealth of opportunity for blockchain technology within the medical sector, little has been done thus far. Unfortunately, this is an innate problem with the current focus of medical technology. Great effort has been put into the development of advanced medical devices and AI healthcare tools. Sadly, the essential IT systems, mainly Electronic Health Records (EHR) on which the hospitals are built, have been much the same for many years. In some cases, many hospitals still record medical information via handwritten notes.

A lack of innovation in the way we store and interact with patient data is causing problems across the sector, both in the efficiency of hospitals and the protection of private information. In extremis, it is resulting in severe practitioner frustration, unsafe conditions, and delayed/incorrect treatments being performed. …
