Propofol

This is a small iPhone app to visualise the effective concentration of Propofol based on the three-compartment Schnider model. It was created in 24 hours at the NHS Hackday in Liverpool.

This is a very rough alpha version and should not be used in a clinical scenario unless you have a deathwish on behalf of your patient.

App details

• Objective-C
• iOS 6.0 and above

Third-party libraries

• CorePlot

App structure

Parent classes

• App delegate
• CMBaseNavController - subclassed UINavigationController
• CMBaseViewController - subclassed UIViewController

UI classes

• CMVitalsViewController - subclass of CMBaseViewController. Captures patient vitals (height, weight, age, gender)
• CMConcentrationViewController - subclass of CMBaseViewController. Captures desired Propofol Ce value
• CMGraphViewController - subclass of CMBaseViewController. Displays main graph.

Model classes

CMCalculator - implements calculation methods:

• newPatientWithAge:andWeight:andHeight:andMale: - creates new patient
• giveDrugWithQuantity:withState: - adds drug to current patient
• waitTime:withState: - models Ce concentration based on time interval

To do

• Implement CMCalculator as a singleton
• Store the current state in the CMCalculator singleton
• Reimplement automagic scrolling of the graph
• Implement user-controlled scrolling through graph history
• Link user-supplied patient vitals into calculation
• Overhaul UI so that user can set desired Ce value
• Implement alerts and reminders etc
