Abstract:
Arterial blood gas (ABG) analysis is crucial for determining oxygenation and blood
acid levels. It is essential for identifying the clinical status and contributes to healthcare
strategy plans that are both cost-effective and efficient. ABG is most commonly used
in emergency care units (ECU) and intensive care units (ICU). Most of the time,
doctors and nurses face difficulties diagnosing the type of respiratory failure using ABG
test results. So, in this research study, supervised machine learning approaches such
as Extreme Gradient Boosting (XGBoost), Adaptive Boosting (AdaBoost), Catboost,
Random Forest, Naive Bayes, Support Vector Machine (SVM), LightGBM, K-Nearest
Neighbors (KNN), Neural Network (NN), and Decision Tree were applied to determine
the type of the respiratory failure. Since it is a multi-class classification problem, the
target variable consists of three classes: No respiratory failure, Type-1, and Type-2.
The results of 700 patients from a Sri Lankan public hospital were collected for this
study. XGBoost outperformed all other approaches in diagnosing the type of respiratory
failure, yielding the highest accuracy of 98.65 percent and the lowest error rate of 1.35
percent. The dataset was also subjected to K-fold cross-validation using five folds to see
if the XGBoost outperformed against varying training and testing data percentages. The
cross-validation method yields findings with an accuracy of 98.45 percent and an error
rate of 1.55 percent. Finally, XGBoost was used in the development of the prediction
model. The findings of this study provide important insights for a future researcher
who wants to employ hybrid and deep learning approaches to figure out what causes
respiratory failure and how to anticipate the type of respiratory failure.
