Learning Objectives
The Essentials
Most airway training starts with endotracheal tubes and intubation. But in real practice, tracheostomies show up everywhere, and they fail in ways that are easy to miss and hard to recover from. This Essentials section builds the foundation, so you recognize the problem early and respond with clarity when it counts.
What is a Trach
The Procedure
A tracheotomy is a surgical procedure that creates a direct airway into the trachea by making a surgical opening in the front of the neck. A tracheostomy can be life-saving for patients who need long-term ventilation, upper airway bypass, or secretion management, but it also changes the normal rules of airway care. The tracheostomy tube facilitates breathing by providing an alternative airway route that bypasses the upper airway, including the nose and mouth.
The Critical Language
You’ll hear people say “the trach” all the time on rounds or in the ED. What they usually mean is the tracheostomy tube, not the actual tracheostomy. It’s shorthand, and in casual conversation, it works. But early on, it’s worth being more precise so you build the right mental model.
Here’s the clean way to think about it:
- Tracheostomy = the hole in the neck that leads into the trachea
- Tracheostomy tube = the device sitting in that hole
Early learners tend to anchor on the device. Experienced clinicians think about the airway first, device second. So here’s a simple rule I’d give you:
In conversation, people will say “trach” and mean the tube.
In your head, always separate the hole from the hardware.
If you build that habit now, you’ll make better decisions later, especially when things go sideways.
Why It Matters
Whether you’re in the ED, ICU, OR, or on the wards, you will encounter patients with tracheostomies, and when things go wrong, there’s no time to Google. That’s why getting familiar with trach anatomy, the equipment, and how to respond to trach emergencies isn’t just helpful — it’s essential.
Why is this learning space relevant? Let’s share a few numbers with you. If you work in an emergency department, hospital, or pre-hospital setting, chances are you will see a catastrophic event related to trachs. Here’s why. (US Data).
Clinical Anatomy

The Anatomy That Makes a Difference
If you strip this down to what actually matters at the bedside, there are only a handful of anatomical facts that change how you manage a tracheostomy patient. Everything else is noise.
Start with the target.
A tracheostomy is an opening into the trachea, almost always created between the 2nd and 4th tracheal rings. That location matters because it defines where your tube sits, where complications occur, and what structures are at risk. The trachea itself is a semi-rigid tube with anterior cartilaginous rings and a softer posterior membranous wall that sits right up against the esophagus. If you push a tube posteriorly, that’s where injury happens.
Think Layers
Now think about layers. From skin to trachea, you’re going through skin, subcutaneous tissue, strap muscles, and pretracheal fascia before you reach the tracheal rings. In a fresh tracheostomy, that tract is not mature. It’s just a hole. Lose the tube early, and you lose the airway. In a mature trach, the tract becomes epithelialized and behaves more like a stable conduit.
Adjacent Structures
The next piece that actually matters is the relationship to the thyroid and vessels. The thyroid isthmus typically overlies the 2nd to 3rd tracheal rings. It often gets divided or retracted during placement, but it can still be a source of bleeding. More importantly, the innominate artery lies just anterior and slightly inferior to the aorta. That proximity is why a low tracheostomy or excessive tube pressure can erode into it and cause a tracheo-innominate fistula, one of the most lethal airway complications you’ll ever see.
Two Airways
Then, understand the two-airway concept. A patient with a tracheostomy has:
- an upper airway (mouth and nose to larynx), which may or may not be usable
- a lower airway accessed directly through the trach
You cannot assume the upper airway is patent. Patients with laryngectomies cannot be oxygenated or intubated from above. Many trach patients also cannot be intubated from above due to obstruction, surgery, or edema. That assumption gets people into trouble.
What is Near the Tube
Tube size and shape matter. The cuff, when present, seals the airway for ventilation but also exerts pressure on the tracheal wall, where ischemia and later complications begin. The tip of the tube should sit a few centimeters above the carina. Too shallow, and it dislodges.
Bleeding follows anatomy and pressure. The severity ranges from nuisance oozing to a catastrophe, and you need to know where along that spectrum you are within seconds.
Start at the surface.
At the stoma, bleeding usually originates from the skin edges, subcutaneous tissue, or small anterior neck veins. It’s common early after placement or with tube movement. This is the “annoying but not dangerous” zone. It looks messy, but it doesn’t usually threaten the airway or circulation unless it’s brisk or persistent.
Move one layer deeper.
Around the tract, you can get bleeding from the thyroid isthmus or small vessels in the pretracheal tissues. This tends to be more than just oozing.
Now get to the part that actually kills people.
The innominate artery (brachiocephalic trunk) crosses the trachea anteriorly, usually around the level of the 6th–9th tracheal rings. That’s just inferior to where most tracheostomies are placed. If the tube sits low, if the cuff pressure is high, or if the tube tip is constantly rubbing anteriorly, it can erode through the tracheal wall into that artery.
That’s a tracheo-innominate fistula (TIF). It’s rare, but when it happens, it’s one of the most lethal airway emergencies you’ll see. A tube that can obstruct, dislodge, or bleed into a space that has very little margin for error.
Everything you do in a tracheostomy emergency comes back to that.
Anatomy & Trach Tube Location
You don’t need to know how to perform a tracheotomy—but you do need to understand the anatomy well enough to manage a tracheostomy emergency. Here’s what matters:
- Tracheal Rings: Most tracheostomies are placed between the 2nd and 3rd tracheal rings, just below the cricoid cartilage. This landmark helps orient you to the typical tube location.
- Stoma: The opening in the neck is the stoma, a surgically created tract that connects skin to trachea. In fresh trachs (<7 days), this tract isn’t mature—making dislodgement dangerous and reinsertion risky.
- Major Vessels: The innominate artery crosses the trachea around the lower third, usually near the 6th–7th tracheal rings. This is why bleeding, especially delayed bleeding, should always raise concern for a tracheoinnominate fistula (TIF).
- Esophagus & Posterior Trachea: The esophagus lies just behind the membranous portion of the trachea. A misplaced or over-inflated cuff can cause posterior wall injury or fistula formation.
- Upper Airway Connection: In patients with a standard tracheostomy, the upper airway (mouth and nose) remains patent. This means oxygenation and ventilation from above is still possible—unless the patient has had a total laryngectomy, in which case the stoma is the only airway.

How to Safely Manage This Device
What You Need to Know
Let’s cut through the noise. These are the essentials. Want to go deeper? Scroll down to the Deep Cuts section. If you’re in one of our immersive pop-up spaces, hit the linked station for hands-on practice and next-level skills training.
Begin by reviewing the infographic and scanning the available digital content. After that, engage with the sample tubes provided at our interactive pop-up station. By the end of this activity, you will be able to identify the key features of tracheostomy tubes, enabling you to confidently manage this critical device. By the end of this session, you will be able to:
- Recognize that trach tubes vary in design to meet patient needs
- Identify key features: cuff, cannula, fenestration, size
- Understand how design affects ventilation, suctioning, communication, and emergency response
- Know where to find tube info and why small details matter
If you manage airways, you need to be confident when dealing with tracheostomy emergencies. That means knowing your way around a tracheostomy tube, also known as a “trach tube” or just “trach”. Whether you’re in the ED, ICU, OR, or on the floor, a trach-dependent patient won’t wait for you to figure it out — and that confidence starts with knowing the gear.
Tracheostomy tubes aren’t “one size fits all.” They vary widely in shape, features, and function to meet a patient’s specific needs. While the overall design may look familiar, those details—cuff, cannula, fenestration, size—can directly impact airway management, ventilation, suctioning, and patient safety.
Understanding these variations helps you anticipate complications, communicate effectively, and deliver safer care, especially in emergency situations. Remember, that tracheostomy tube isn’t just a piece of plastic — it’s your patient’s lifeline to oxygen. In this station, we’ll break it down: the key parts, the variations, and the features that matter when seconds count.
So let’s get familiar with the essentials: Is the tube cuffed or uncuffed? What’s the size? Does it have an inner cannula? Is it fenestrated? These features shape how you respond under pressure. And knowing how to find that information is a core part of trach management.
Because small design differences can have big clinical consequences.
🔑 Key Features of a Tracheostomy Tube
Signal Over Noise
For such a “simple” device, there are a surprising number of details—tiny stenciled labels, odd little doo-dads inside and out. In an emergency, how do you cut through the clutter and focus on what really matters? It’s easy to get overwhelmed, but if you know what you’re looking for, the rest falls into place.
Let’s start with the most important features in this short video, then review the content below before moving on.
Don’t Forget This!
That Extra Piece of Plastic…
The obturator is a stiff, rounded device designed to assist with the safe insertion of a tracheostomy tube. It slides inside the outer cannula to create a smooth, blunt tip that reduces the risk of tissue trauma during placement. Once the trach tube is inserted, the obturator is immediately removed, allowing airflow through the tube and insertion of the inner cannula if needed. It’s not used during routine care or emergencies — its role is strictly for guiding initial tube placement or reinsertion.
A Couple of Important Microskills
You’d think there’d be one standard design for tracheostomy tubes—especially when it comes to safety. But nope. Most cuffed tubes do have a Luer lock on the pilot balloon, but the inner cannulas? That’s where things get annoying. Different brands use different connectors—some snap in, some twist and click. It’s not always obvious which is which.
Here’s a look at a twist-and-lock version. Be sure to get hands-on practice with these microskills—they can trip you up when it counts.
Features of Trach Tubes (Expanded Edition)
1. The Tube Itself (Outer Cannula)
- A short, curved cannula is inserted through the tracheostomy stoma directly into the trachea.
- Comes in different materials (PVC, silicone, metal) and sizes — always check the inner diameter (ID), not just the outer!
2. Inner Cannula
- Many tubes have a removable inner cannula that can be cleaned or replaced.
- Clogged cannula = blocked airway — check it early in any decompensation.
3. Cuff vs. Cuffless
- Cuffed tubes seal the airway, protect against aspiration, and allow positive pressure ventilation.
- Cuffless tubes are for stable patients with an intact upper airway.
- Always know the cuff status — and never overinflate (unless for TIF).
4. Flange (Neck Plate)
- The external plate that rests on the skin and secures the tube with ties or Velcro straps.
- It displays the size and type of the tube — use it for a quick ID in emergencies.
5. Pilot Balloon
- Connects to the cuff, providing tactile and visual feedback on inflation status.
- Flat balloon? Likely deflated vs leak.
- Tense balloon? Inflated cuff — but don’t over-inflate, confirm cuff pressure.
6. 15 mm Connector
- Standard port that allows you to hook up to a bag-valve mask or ventilator circuit.
- All trach tubes should be connectable — if not, have an adapter ready.
7. Obturator
- Inserted into the outer cannula of the device before being placed to protect the patient from injury during insertion.
- The inner cannula must be removed and set aside in a safe location, then reinserted after placement.

Tracheostomies are simple devices, but if you’re not familiar with their basic design and some of their variations, they can be more intimidating than they have to be. Let Dr. Crane walk you through the various features of this device (9:43 min).
The Bottom Line
Understanding tracheostomy tube design isn’t a minor detail—it’s essential to safe care. Whether the tube is cuffed or uncuffed, its size, the presence of an inner cannula, and whether it’s fenestrated all directly affect how you suction, ventilate, communicate, and manage emergencies. Knowing how to find this information is a core part of trach management. When in doubt, speak up. Small design differences can have big clinical consequences.

Why read Chapter 15?
If you take care of patients with tracheostomies, this chapter is non-negotiable. NAP4’s deep dive into tracheostomy disasters shows how minor problems become lethal when teams lack a plan, miss displacement, or fail to recognize tube obstruction early. It’s a brutal but honest look at real-world failures: dislodgement during turns, misplaced tubes, missing equipment, delayed help, and the deadly absence of capnography. The cases are raw, the lessons are clear, and the recommendations are practical. Read the original — your future patient might depend on it.
The Procedure – Placing a Tracheostomy
The Trach Procedure
When performing a tracheotomy, additional anatomical knowledge is required. While you don’t need to know these details to manage tracheostomies, understanding them can be informative about the procedure itself. Here it is.

Key Take-Home Points: Tracheostomy (StatPearls Review)
Here are the key take-home points from the NCBI review on Tracheostomy (StatPearls, updated 2024): It’s worth a full read when you have the time.
1. Indications
- Tracheostomy is performed for airway obstruction, prolonged mechanical ventilation, or airway protection.
- Common scenarios include neuromuscular weakness, trauma, head and neck cancers, and chronic pulmonary disease.
2. Timing
- Typically considered after 7–14 days of endotracheal intubation in patients expected to require prolonged ventilation.
- Early tracheostomy (≤7 days) may reduce sedation needs and ICU length of stay, but has mixed data on mortality.
3. Techniques
- Two main types:
- Surgical tracheostomy (ST) – usually in the OR
- Percutaneous dilatational tracheostomy (PDT) – often at the bedside in the ICU
- PDT is now common in ICUs due to its minimally invasive nature and lower complication rates when performed by experienced providers.
4. Anatomy & Procedure
- The tracheostomy is typically placed between the 2nd and 4th tracheal rings.
- Knowledge of neck anatomy and avoidance of vascular structures is essential.
5. Complications
- Early: Bleeding, pneumothorax, subcutaneous emphysema, false passage.
- Late: Infection, tracheal stenosis, tracheomalacia, granulation tissue, tracheoesophageal fistula.
- Meticulous technique and postoperative care can reduce these risks.
6. Postoperative Care
- Requires humidified air, suctioning, cuff management, and attention to stoma hygiene.
- Communication and swallowing assessments are key in long-term care.
7. Emergency Considerations
- Dislodgement or obstruction of a fresh (<7 days) tracheostomy is a medical emergency—do not blindly reinsert the tube.
- Immediate options: oral airway with BVM, intubation, or surgical airway, depending on the clinical context and tube maturity.
8. Interprofessional Collaboration
- Optimal outcomes require coordinated care among surgery, intensive care unit (ICU), nursing, respiratory therapy, and speech-language pathology teams.
The Bottom Line
You don’t need a surgeon’s roadmap—you need a working understanding of what’s connected, what’s at risk, and what to expect when things go wrong. This knowledge is critical for making fast, safe decisions in tracheostomy emergencies.
The Bottom Line
Tracheostomies are common, high-risk, and unforgiving when mismanaged. Learn the anatomy, familiarize yourself with a tracheostomy tube, and be prepared to respond to common emergencies associated with a tracheostomy. Your confidence in what you learn here could save a life.
