The Body Mass Index Calculator.

Posted on May 10, 2021 by paulcullenphotography

Hello and welcome back. My latest Flutter and Dart project is my body mass index calculator or as some know it BMI. Body mass index is a somewhat out of vogue way of assessing if someone is of a healthy weight for their height and quite rightly so, many a professional Rugby player will have a BMI of 35 or above, particularly those forwards who are all muscle and muscle weighs more than fat. A safer option would be to assess %fat content but that is more difficult so I think that BMI calculation will be around for a bit longer yet so this app may well prove helpful. The calculation for body mass index is:-

BMI = weight in kilograms / (height in metres x height in metres) (substitute * for x if you prefer!).

My app also has a calculator for conversion of imperial weights (stones and pounds – British not US) to metric (kg), and another for imperial height or length (feet and inches) to metric (metres) which can them be used for the BMI calculator. I have included a calculate button for each calculation and a reset button to clear all of the boxes.

The Flutter Version of the BMI Calculator app.

It is the Flutter version of part of a previous Android app with several calculators within it. My intention is to ask those to whom I show all of these Flutter calculation apps which ones they would like to see as a suite and which would not be useful to them. I intend to have several sites; perhaps a paediatric suite and an adult based suite and target them at appropriate audiences. If you have any thoughts on the matter, please feel free to share them with me. Thank you.

My Quiz App.

Posted on May 2, 2021 by paulcullenphotography

My daughter is a primary school teacher and holds a Master of Arts Degree in History. I thought that it would be a jolly wheeze if I was to attempt to create a quiz app that might be useful to her endeavours, or at least amuse her. It would also give me an idea for a project – sometimes as an app developer, finding an idea for a project is the most difficult thing. I made it and although it wasn’t suitable for her target audience, I am quite proud of it. There are problems with it, such as the fact that it is difficult to make out the text in front of the background illustrations (some of which are my photographs – Eilean Donan Castle and Gallos from Tintagel castle – look it up!) but it was progress.

The front page and links to the other four pages.

It was a first attempt at a quiz app for more than as an educational project. I had created a much less elaborate quiz as a project for my Udacity Android Basics Nanodegree; this quiz was based on the techniques that I had used then. I had created each quiz in a ScrollView – it seems to be frowned on now but I thought it appropriate at the time. The questions use a selection of radio buttons (only allows one choice), grouped check boxes (allows a pre-set number of choices) and each quiz has an edit text (user text input). When the user presses ‘Submit Answers’ it tells them how many points out of a maximum score and if they achieve a perfect score, it displays another message which tells them that they scored a maximum ” ” points (it varies between the quizzes). Finally, each individual quiz can be reset by pressing – you guessed it , the ‘Reset’ button. What’s not to like?

‘Bye for now, I’ll see you next time…

The first draft of the medical calculations app – created in Android Studio.

Posted on May 1, 2021 by paulcullenphotography

I wanted to create something useful and given my background in Nursing and all things medical, I was naturally inclined to come up with something that might prove useful to my former colleagues and those who perform a similar role as that is what I know most about.

One of the things that computers do well (and your mobile device is a sophisticated computer) is crunch numbers quicker than a speeding bullet and certainly faster than human brains and what is more, if they have been given the right instructions in the first place, they will do it faultlessly at every time of asking – better than humans there too then. In short, I wanted to simplify peoples lives by taking away some of those routine calculations. Here is my first attempt. It was written in Android Studio solely to work on Android devices. In later iterations I added extra functionality to it, of which I will tell you at a later time. For now, this is the first version:-

The first medical calculations app for Android.

Detail of Android version of Paediatric Resuscitation app for Android

If you want detail about how the resuscitation app works, please see the Flutter version post from a couple of days ago. I’ll talk about the fluid calculation app soon. See you later…

How to calculate the skin area of a child.

Posted on April 30, 2021 by paulcullenphotography

It is probably not on your usual list of daily considerations but for some people it is. Those people are very talented doctors who treat children and in particular very small children as this calculation is used to decide what dose of drugs to give to these children and to decide on other very critical treatments.

The calculation is:-

Body Surface area = the square root of ((weight in kilograms x length in centimetres)/3600)

The method is known as the Mosteller method.

As it appears in the emulator in Android Studio.

Users type in the weight and length and press ‘Calculate’ then to reset the app press ‘Reset’ – simples…

Again, this app is quite niche but may prove useful if this is your line of work. The final outcome is likely to be that this will be included as part of a suite of specialist applications. In this form I hope to make it available for both Android and iOS. See you soon…

Paediatric Resuscitation App in Flutter.

Posted on April 29, 2021 by paulcullenphotography

You have recently read about how I spent a bit of time studying Flutter and Dart with a free course from Udemy. The first personal project that I have commenced is to convert a medical calculations app that I initially created in Android. It included an app to calculate drug and fluid doses used in paediatric cardiac arrest, a body mass index calculator, a fluid infusion rate calculator, a body surface area calculator (used to calculate drug doses for babies), and two metric unit calculators which work in different ways (volumes and lengths). In it’s original form, the app would only work on Android devices. I wanted to present an app or a series of apps that can be used on both Android and iOS so to recreate them in Flutter would be one way of achieving that.

I decided to convert each part of the original Android app separately and I started with the Paediatric Resuscitation dose calculator.

The Flutter version of my Paediatric Resuscitation Calculator.

The Android version (set in ScrollView).

When children get sick it is often not serious but they can deteriorate very quickly and when they do it is important to recognise the signs and act upon then quickly. Often it is to do with dehydration, sepsis due to infection, a low blood sugar or trauma and the story with which they present may give you clues as to what the problem is. A thorough assessment of the patency of their airway, their work of breathing, their circulation, their level of consciousness and any injuries over the whole of their bodies – correcting problems as you go in this priority order is the way to go – not leaving ‘any stone unturned!’. Hopefully, you can reverse the decline and make the child well again. This is the best outcome. Sick children tend to be very resilient to a point and it is up to this point that you have the best chance of success and this success comes by good assessment as above BUT if that window of opportunity is missed the sick child will ‘crash’ quickly and may even go into cardiac arrest. The calculations made by this app are those taught to Doctors, Nurses and other healthcare professionals in how to deal with very sick children and those who have gone into cardiac arrest. The Resuscitation Council UK and the European Resuscitation Council Paediatric resuscitation courses teach these calculations in the case of Paediatric Cardiac arrest. In practice, paediatric resuscitation teams are calculating these numbers as they chase down the hospital corridors to respond to the emergency but my motivation for writing this particular app was for the paediatric ward nurses and doctors who would be involved with resuscitating the child so that they can be be better prepared with drugs and fluids when the ‘team’ arrives. In my experience of being an instructor on Paediatric Resuscitation courses it seemed to me that whilst the attendees were able to do the calculations, they had to have a refresher about what formulae to use as they were not using them all of the time so if it were used it might save them preparation time and stress.

All of the calculations are based on the child’s age as this is reckoned to provide to most accurate calculations in this situation. Users of this app just type in the child’s age and the app will calculate the child’s (likely) weight, the size of uncuffed endotracheal tube (for those under 8years old), the size of cuffed endotracheal tube (for those 8 and over), how much of a DC electrical shock to give them – measured in joules and based on their calculated weight, how much crystalloid fluid to give as a bolus (isotonic sodium chloride or compound sodium lactate) which can be repeated if necessary, how much adrenaline to give as a bolus (which can be repeated every three to five minutes), how much amiodarone could be given if necessary and how much glucose can be given if necessary for very low blood sugar.

Not all of these calculations will be needed but by the same token some of the calculations would be appropriate for emergency treatment of very sick children, not just those in cardiac arrest. Young children particularly will collapse and even arrest due to low fluid volume – dehydration (due to diarrhoea, vomiting, haemorrhage or severe sepsis – the fluid calculation will be of particular importance), low blood sugar (so the glucose calculation will be important). It is unusual for a young child to suffer from a primary cardiac cause unless they were born with it. With severe dehydration there can be a salt imbalance which can cause cardiac problems. It is with older ‘children’ that a primarily cardiac cause might be suspected as adolescents and young adults can suffer from sudden arrhythmias which can cause collapse and cardiac arrest. This is mainly where the DC Shock and amiodarone calculations come into play most frequently as they are used to correct these arrhythmias. The DC shock is delivered by a defibrillator (in manual mode usually by a medical professional with proven rhythm recognition skills.

It is a bit niche but I think that it could be useful for those less familiar with the calculations but may be called to assist in the ‘resuscitation’ (including fluid resuscitation) of a child in a non-critical care healthcare environment such as a standard children’s ward. Once I finish the whole suite of calculation apps in Flutter, I will consult with a former colleague of mine from when I was a Resuscitation Officer who is Lead Paediatric Officer at my local (large) NHS Trust to see what she thinks about it. I showed her photos of the original Android version and she expressed an interest so we will see. Wish me luck!

For those of you that want to see pictures of Android Studio:-

Until next time, take care and stay safe…..

Graduation!!!!

Posted on March 29, 2021 by paulcullenphotography

I graduated with Android Basics Nanodegree by Google and through Udacity on the 31st July 2018 – I think that the cut-off date was 20th August 2018 so I was only a few days ahead of schedule. Udacity extended the deadline by a few weeks because I think that there were still quite a few people who were going to miss it! After the extended deadline, the people who had still not completed were given a “preferential rate” in order to complete, which several people took advantage of.

I was ever so proud as you might expect but then I started to think “now what do I do?” The tutors on the course suggested that we use our new found knowledge to adapt the projects that we had created throughout the course to fit the needs of local shops and businesses in our areas. For me it was a question of confidence and a search for ideas about how I was going to proceed. More about that next time….

The Tour Guide App

Posted on March 24, 2021 by paulcullenphotography

We had started to create multi-page apps and now to build on that we were tasked with building a Tour Guide app. The brief was to make our own multi-screen Android app to share our knowledge about a city that we knew well. It was to include top attractions, restaurants, public places or events for the city. We were shown how to create proper data structures to store lists of information and then build layouts to display those lists of data. We were to navigate through those lists in Fragments using a ViewPager or Navigation Drawer; creating out own custom classes to do so and properly handling images and/or audio if applicable.

I chose to base my Tour App on the City of Nottingham and I included places to stay – mostly hotels, places to eat – restaurants and takeaways, places to explore like Theatres and castles, and finally, a section on Museums. Each item on each of the lists when clicked takes you to the venue’s website and navigating between lists is as easy as a swipe left or right.

Creation of this app introduced me to allowing permissions in the manifest (Internet) and making those Arrays of the data and image assets. It was also the first time that I had come across Fragments usefully. I had read about them in Stack Overflow posts but until this time they had remained some mystical far off land to be explored sometime in the future. We were also encouraged to up our game in terms of styling and polish of our app. I was very pleased with this app and I may well go back and add extra venues and categories to make it more complete and useful – once the Covid-19 pandemic is over and people can get out to visit these sorts of places.

When most people think of Nottingham they probably think “Robin Hood” who was probably not a real person but a couple of fun facts; D.H. Lawrence lived and wrote just outside of Nottingham in Eastwood and William Booth founded the Salvation Army in Nottingham and there is a museum to him and the Salvation Army in Nottingham centre. It is in my app just a bit lower on the museums page.

Are you sitting comfortably…

Posted on March 19, 2021 by paulcullenphotography

As you may well have read in my “About” section, I was once a Registered Nurse and later, a Resuscitation trainer – this little factoid will come in useful once I get to the bit where I describe what I have been working on recently. Please bear with me. I had always taken photographs and thought that it would be a jolly wheeze if I was to retire early and make a living as a photographer. I have a photography blog which gives a fuller picture of the photography adventure (link on header to each page if you are interested – please visit at least once) but suffice to say, it didn’t bring the fame and fortune that I craved. During that time I started to play with Android photo editing apps on my phone after a very talented photographer called Gerry Coe came to the local camera club that I attended. He had won numerous awards for his photography and had moved on to win awards with his iPhone photography. I was hooked. I started to play with Snapseed, Picsart, PhotoLabPro, Prisma, and a whole lot more using my photographs and posting them on my Photo Instagram page*. My next thought was to see if I could find out how to write an Android photo app for myself. I mentioned this to a friend of mine one evening at the camera club and the following morning, he sent me a link to Google Garage where they were offering scholarships to study for one of four Google Nanodegrees.

Android (advanced) Web development Nanodegree

At the age of 56 I decided to apply for the Android Basics Nanodegree; I did not have any previous experience of writing code, just a kid with a crazy dream!

I applied and was accepted. The course was run by Udacity and the first stage was “The Google Developer Challenge”

The scholarship was for three months and there were 20,000 selected across Europe for each of the two basic strands and 10,000 for each of the more advanced strands. I did well in the first phase and was given another scholarship to study for a further six months for the full Nanodegree. There were only 2000 people on each strand invited to continue and I was one of the fortunate ones.

There will be more about my journey through my Nanodegree with Udacity in my next post.

*I have two Instagram pages; a photography page (@paulcullenphoto) for which there is a link through my photography website and a new “Developer” page (@cullendevelopment) to which this website is linked.

I have a third site “uncorked bottle” (link under header on each page) if you are interested in my wine blog.
