Oxygen Delivering System I: Nasal Cannula and Face Mask

Oxygen Delivering System I: Nasal Cannula and Face Mask

The human body requires oxygen to function, and when the natural process of respiration is hindered, external devices, including the following, are needed to help deliver this vital gas.
Nasal Cannula
A nasal cannula is a lightweight tube split at one end into two prongs and placed in the nostrils. It is typically used to deliver low to medium levels of oxygen.
Suggested flow rate: The suggested flow rate for a nasal cannula typically ranges between 1 and 6 L/min.
Oxygen percentage setting:...

Suctioning the Nasopharyngeal Airway

Suctioning the Nasopharyngeal Airway

Nasopharyngeal suctioning is a procedure to remove secretions from the upper part of the respiratory tract that the patient cannot clear independently. It helps maintain airway patency and prevents complications such as aspiration pneumonia.

Background:

Accurate sizing of nasal Positive Airway Pressure (PAP) masks is crucial for patient comfort and adherence to therapy.
Manual PAP mask sizing can be time-consuming and subject to variability.
Facial image analysis offers a potential for automated and objective mask sizing.

Purpose of the Study:

To develop and evaluate a deep learning model for automated nasal PAP mask sizing using patient facial images.
To assess the accuracy of the proposed model in predicting appropriate PAP mask sizes.

Main Methods:

A deep Unet convolutional neural network with a VGG16 backbone was utilized.
The network was trained on the MUCT dataset with extensive data augmentation.
The model was subsequently applied to a custom dataset of patients to predict nose widths and PAP mask sizes.

Main Results:

The Unet model achieved a mask sizing accuracy of 63.73% (116/183).
An accuracy of 88.5% (162/183) was obtained for within-one-size predictions.
The model demonstrated effectiveness in automated PAP mask size prediction.

Conclusions:

Deep learning, specifically the Unet architecture, provides a viable automated solution for nasal PAP mask sizing.
This AI-driven approach has the potential to streamline the PAP mask fitting process.
Improved mask sizing accuracy can enhance patient compliance and therapeutic outcomes in PAP therapy.
