Appropriate vs Lateral Puncture

Double‑Lumen Tube via Stoma

Lateral Puncture Risks (Force Vectors)

Mini‑Open (Marks and Final Appearance)

Percutaneous Dilatational Technique (Ciaglia)

Single‑Use Flexible Bronchoscope (SUFB)‑Guided PDT

Transillumination Landmarks (PoCUS Correlate)

Tube Insertion over Introducer

Ultrasound (Cannula Tip at T1)

Ultrasound – Trachea longitudinal view (cricoid and tracheal rings, 8 MHz probe)

Ultrasound – Trachea sagittal view (cricoid cartilage and five tracheal rings)

Ultrasound – Trachea sagittal view (guidewire entry point identification)

Ultrasound – Tracheal puncture (axial view with needle at anterior wall)

Ultrasound – Tracheal vascular anatomy (duplex imaging, paramedian artery avoidance during puncture)

Ultrasound – Centralized tracheal puncture guidance

Ultrasound – ETT positioning (tracheal longitudinal view with cricoid and tracheal rings)

Ultrasound – Guidewire confirmation (axial view, right of midline)

Ultrasound – Guidewire confirmation (longitudinal view, tracheal rings)

Procedure – Tracheostomy anatomical landmarks (fiberoptic guidance, depth marking, puncture angle)

Procedure – Tracheostomy Ciaglia method (dilation and cannula insertion)

Procedure – Guidewire positioning (14G IV catheter insertion)

Ultrasound/Clinical – Tracheal transillumination with PoCUS guidance (cricothyroid membrane and puncture point)
