Obesity and neck posture impact tracheostomy tube displacement risk. Pretracheal tissue depth, measured via ultrasound, correlates with Body Mass Index (BMI), aiding in predicting displacement probability.
Area of Science:
- Medical Devices
- Clinical Trials
- Anatomy
Background:
- Unintentional tracheostomy tube displacement is a common complication.
- Obesity-related pretracheal soft tissue thickness is a key risk factor.
- Postural changes can alter intratracheal tube length, increasing displacement risk.
Purpose of the Study:
- To analyze the relationship between postural variations in pretracheal tissue depth and Body Mass Index (BMI).
- To identify predictive markers for tracheostomy tube displacement.
Main Methods:
- Prospective clinical trial involving 100 patients.
- Ultrasound measurement of pretracheal tissue depth in neutral and extended neck positions.
- Calculation of BMI using patient weight and height data.
Main Results:
- Pretracheal tissue depth differences correlated with neutral depth (r=0.721) and BMI (r=0.436).
- Moderate, positive, linear correlations were found between BMI and pretracheal tissue depth (neutral: r=0.574; extended: r=0.486).
Conclusions:
- Postural variations in pretracheal tissue depth are linked to BMI.
- Ultrasonographic measurement of pretracheal tissue depth may predict tracheostomy tube displacement risk.

Assessment of Ventilation II: Respiratory Depth and Rhythm
Respiratory depth measures the volume of air inhaled or exhaled during a breath. It can vary from shallow to deep and typically remains consistent when a person is at rest or asleep. Occasionally, individuals will automatically inhale deeply, known as sighing, which inflates the lungs with more air than normal breathing.
To assess respiratory depth, observe the degree of chest excursion or movement:
