Getting started

Linux

$ apt-get install libcairo2-dev libgirepository1.0-dev python3-cairo-dev

Mac

$ brew install pygobject3 gtk+3 libnotify

App (Python 3)

From ./gui

Install system dependencies (Debian-based):

$ pip install -r requirements.txt
$ ./main.py

Requirements:

2 ventilators mode

  • Pressure Regulated Volume Controlled (PCV): set pressure delivered during period of inspiration. The voume measured is shown as data on display.
  • Volume Regulated Pressure controlled (VCV): The tidal volume is set and it adapts the pressure to the lowest. Here the important data are: tidal volume, upper alarm and lower current volume. Useful parameters: tidal volume, respiratory rate. There is a limit pressure and during inspiration period.

If patient stops breathing, there is a failsafe that set to mandatory breathing when it's detected.

During inspiration:

  • Inspiration pressure: The plateau pressure is adjusted to volume hard limit (32 cmH2O by default, and could increate to 70cmH2O)

  • Peak pressure: 2cmH2O greater than plateau.

  • VCV pressure limit (15-40cm2 with increments of 5)

  • Failsafe valve that opens always at 80cmH20 (or lower)

  • PEEP: 5-10 with increments of 5. The circuit must be pressured.

  • IE ratio: 1:1, 1:2, 1:3

  • Respiratory rate: 10-30 bpm with increments of 2.

  • Tidal volume: 40ml +-10, 350 +-50, 250-600 +-50,up to 8000.

  • Weight body and volume calculated based on 6ml/kg.

Alarms

  • Gas failure
  • Electricity failure
  • Machine switched off
  • Inspiration pressure exceeded
  • Inspiration pressure not achieved
  • PEEP pressure not achieved
  • Tidal volume not achieved
  • Tidal volume exceeded
  • Resistance: peak pressure - plateau pressure > 2cmH2O
  • Compliance
  • Volume Leakage

Monitoring

Settings

  • Tidal volume
  • Frequency
  • PEEP
  • FI02
  • Ventilation Mode

Current status

  • Tidal volume
  • Breathing rate
  • PEEP
  • Plateau pressure
  • FI02

The normal healthy O2 consuption is 250mL/min, and could be increased until, for example 500 mL/min in a sepsis.

Parallel measures

  • Presión arteria
  • Frecuencia cardiaca
  • ECG
  • Nivel de sedación
  • Posicion del tubo e inflado del neumotaponamiento
  • Intercambio gaseoso (pulsiometria SO2), capnografía y gasometrías arteriales periodicas para obtener los índices de oxigenación (clave para evaluar la desintubación del paciente).
