Code for EBPOM 2020 Abstract: Wearables for Home Post-op Monitoring

Code for my abstract “Wearables for Home Post-Operative Monitoring: Proof of Concept” submitted to Evidence Based PeriOperative Medicine 2020 Imports fitbit data, via the web API and fitbitr package, into R.

Wearables: Heart Rate Data from FitBit - Part 2

In Part 1 we explored using the fitbitr package from teramonagi and the fitbit Web API to extract Heart Rate Time Series Data. In Part 2 we will use a Personal application API key to access Intraday Time Series Data, giving us heart rate data with a greater temporal resolution e.

Building a Website with Hugo/Academic

I decided to write this post as I felt that the documentation from Academic, whilst excellent, was very much angled towards using netlify. Although netlify looks like a slick deployment system, I wanted to learn the process of building a classic GitHub Pages website from ‘getting my hands dirty’!

‘Shielded’ anaesthetists and intensivists during the COVID‐19 pandemic

We are clinicians who are part of the ‘shielded’ or ‘extremely vulnerable’ group, as determined either by the government [1] or local policy. Whereas we appreciate the unprecedented and rapidly evolving nature of this situation, our group has been conspicuous by its absence from organisational guidance.

Subdural haemorrhage following epidural top-up for caesarean section

Background & aims Subdural haemorrhage after epidural is a rare complication, which can pose diagnostic challenge given the varied differentials for intrapartum headache. We present a 30-year-old fit and well female at 40 weeks and 2 days gestation with an epidural uneventfully sited.

Creating a Portable High-Fidelity ECMO Mannequin for Developing an ECMO-assisted CardioPulmonary Resuscitation (eCPR) Programme

Background eCPR is a complex process requiring multiple team members to conduct technical procedures in a coordinated, time-critical fashion. Simulation has an increasingly well recognised role in medical training, particularly in the field of critical care, allowing non-technical skills to be honed and logistical challenges to be identified and solutions sought in a safe environment.
