A toolbox to extract data from the ASL5000

Project description

PyPI version


A bunch of functions to extract data from the ASL 5000.

What's the ASL?

The ASL 5000™ is a breathing simulator capable of simulating a wide range of patients, produced by IngMar Medical©. It is mainly used for educational purpose, developing products and testing ventilators. Check the IngMar Medical website for more information.


The ASL5000 utils can be installed using the pip package manager:

pip install asl5000-utils


Let's our environment be:


import asl5000_utils as asl
import matplotlib.pyplot as plt

labels, array = asl.read_rwb("./data/simulation.rwb")
# ['Time (sec)', 'Airway Pressure (cmH2O)', 'Muscle Pressure (cmH2O)', 'Tracheal Pressure (cmH2O)', 'Chamber 1 Volume (L)', 'Chamber 2 Volume (L)', 'Total Volume (L)', 'Chamber 1 Pressure (cmH2O)', 'Chamber 2 Pressure (cmH2O)', 'Breath File Number (#)', 'Aux 1 (V)', 'Aux 2 (V)', 'Oxygen Sensor (V)']
time = array[0]
time_label = labels[0]
curves = [1, 6, 2]  # Paw, Volume, Pmus

fig, ax = plt.subplots(len(curves), 1, sharex=True)
plt.title("Example: visualizing the rwb data using matplotlib")
for i, index in enumerate(curves):
    ax[i].plot(time, array[index])

for a in ax:


In the same way, you can use asl.read_avb or asl.read_brb to read data/simulation.avb or data/simulation.brb.
