# Comparison of clinical, capnography and ultrasonography methods for ETT placement: An observational study

## TL;DR

This study compares methods to confirm proper placement of a breathing tube, finding that ultrasonography is a fast and effective alternative to the standard method.

## Contribution

The study provides evidence that ultrasonography is a reliable and faster method for confirming endotracheal tube placement.

## Key findings

- Ultrasonography and capnography showed excellent diagnostic accuracy for ETT placement.
- Auscultation had slightly lower specificity compared to ultrasonography and capnography.
- Ultrasonography is presented as a faster and effective option in critical settings.

## Abstract

Accurate confirmation of endotracheal tube (ETT) placement is essential to prevent airway complications. While capnography is the
established standard, ultrasonography (USG) offers a rapid, non-invasive alternative. Hence, prospective study of 105 patients was
completed. USG and capnography demonstrated excellent diagnostic accuracy, while auscultation showed slightly lower specificity.
Therefore it is of interest to report ultrasonography as a faster and effective option for ETT confirmation in critical settings.
