You're transporting a stable patient with a possible pneumothorax
The chest tube is still drying. The patient's oxygen saturation is 94% on 2L nasal cannula. Their pain is manageable with the orders you've been given. But somewhere in the back of your mind, you're running through scenarios: What if it collapses further? What if the tube dislodges? What if they start gasping?
This isn't theoretical anymore. You're not reading a textbook—you're making real-time decisions that could mean the difference between a smooth transfer and a code blue in the ambulance That's the part that actually makes a difference..
Transporting a patient with a suspected or confirmed pneumothorax is one of those high-stakes scenarios that separates competent care from exceptional care. It's not just about moving a patient from point A to point B; it's about maintaining that delicate balance between their chest wall and their lungs while navigating the unpredictable variables of prehospital medicine.
What Is Pneumothorax and Why This Matters
A pneumothorax is literally air where it shouldn't be—inside the pleural space between the lung and the chest wall. When that happens, the lung can't fully inflate. It's like a balloon with a hole in it; it deflates and stays collapsed.
There are different types, and understanding the distinction matters for transport decisions:
Primary vs Secondary Pneumothorax
Primary pneumothorax occurs in otherwise healthy lungs, often from a tiny puncture wound or spontaneous rupture of a bleb. Secondary pneumothorax develops on top of existing lung disease—COPD, cystic fibrosis, pneumonia, or trauma. These patients are already compromised, which means they have less reserve when air starts leaking into that space between lung and chest Not complicated — just consistent. No workaround needed..
Open vs Closed
Closed pneumothorax is what most people think of—the air leak is contained within the pleural space. Open pneumothorax (also called sucking chest wound) is more obvious: air enters with each breath because there's an actual opening in the chest wall. That's a surgical emergency requiring immediate intervention, not just transport.
The key thing most people miss? In practice, even a "stable" pneumothorax can deteriorate rapidly. Lungs that are maintaining 94% oxygen saturation on room air can crash to 80% in minutes if the patient coughs hard, gets jostled, or the chest tube shifts.
Why Transport Decisions Are Critical
You're not just moving a patient—you're actively managing a dynamic condition. Every bump in the road, every change in position, every deep breath the patient takes could shift that delicate balance.
Here's what makes pneumothorax transport uniquely challenging:
The One-Lung Principle
When air accumulates in the pleural space, it pushes on the lung, preventing full inflation. But it also pushes on the opposite lung, causing it to overinflate. This is why you'll often see a patient with a pneumothorax leaning toward the unaffected side—the good lung compensates by expanding more.
During transport, you're essentially trying to maintain that equilibrium while everything else is happening: traffic, hospital routines, other patients, equipment failures.
Chest Tube Considerations
If your patient has a chest tube already placed, you're dealing with a controlled air leak system. So the tube allows air to escape but prevents it from re-entering. Still, movement can cause the tube to kink, dislodge, or become blocked. You're not just monitoring for patient deterioration—you're actively managing the tube itself No workaround needed..
Without a chest tube, you're dealing with an open system. In real terms, the longer you wait for definitive care, the larger the pneumothorax becomes. Worth adding: air continues to accumulate. This is why transportation time becomes a critical factor in treatment decisions And that's really what it comes down to. Took long enough..
How to Actually Manage This During Transport
Let's get into the nitty-gritty of what you're doing right now, step by step.
Initial Assessment and Stabilization
Before you even think about moving the patient, you need to confirm they're truly stable. This means:
Vital signs that matter: Blood pressure, heart rate, respiratory rate, oxygen saturation, and pain level. But here's what most protocols don't tell you—watch for subtle changes. A patient whose heart rate creeps up from 95 to 110 might be in early respiratory distress. A saturation that drops from 94% to 91% on the same oxygen flow is significant.
Pain assessment: Pain isn't just comfort—it's physiology. Severe pain causes tachypnea, which increases the risk of tension physiology. If the patient is struggling to communicate because they're too breathless, that's your cue that something's shifting But it adds up..
Chest examination: Before you move them, auscultate the affected side. Note the absence of breath sounds. Compare to the opposite side. Any crackles or wheezes on the unaffected side indicate compensatory hyperinflation.
Positioning During Transport
This is where it gets interesting. Standard teaching says keep the patient flat or slightly elevated. But in practice, you're balancing multiple factors:
The affected side down position: Placing the pneumothorax side down can help slow the progression by allowing air to collect in the most dependent portion of the pleural space, potentially reducing pressure on the lung. That said, this can also make the patient more dyspneic if they're already short of breath.
Semi-Fowler's position: Elevated head of bed 30-45 degrees. This improves ventilation-perfusion matching and reduces work of breathing. Most transport teams default to this because it's generally well-tolerated.
Lateral decubitus with affected side up: This is the "trap position" that can worsen a simple pneumothorax into a tension pneumothorax. Avoid it unless you're specifically trained in positioning for chest tube management Surprisingly effective..
Movement and Handling Techniques
Here's where experience really matters:
Minimize jostling: Don't lift by the arms alone. Use a proper backboard or stretcher sheet, supporting the torso. The last thing you want is for the patient to roll or twist during movement It's one of those things that adds up..
Secure everything: If there's a chest tube, ensure the tubing is properly secured and won't kink. Use a digital recorder or tape to prevent movement. Check that the drainage system is functioning and at the correct height Which is the point..
Monitor continuously: This isn't a "set it and forget it" situation. Watch for changes in respiratory effort, color, mental status, and vital signs every few minutes during transport Worth keeping that in mind..
Communication with Receiving Team
You're not just responsible for the patient—you're responsible for the information flow:
Give specific details: Don't just say "pneumothorax." Say "left-sided pneumothorax, approximately 20% on CXR, chest tube in place, draining smoothly, patient stable on 2L O2, saturation 94%."
Time the transport: How long will it take? What's the fastest route? Are there any anticipated delays? The receiving team needs to know if they're getting a patient who's been mobile for 30 minutes or 3 hours Simple, but easy to overlook..
Anticipate interventions: If you suspect the pneumothorax is getting larger, prepare the receiving team for possible intubation, needle decompression, or immediate chest tube replacement.
What Most People Get Wrong
After years of seeing pneumothorax transports go sideways, certain patterns emerge. Here's what consistently trips people up:
Underestimating the Speed of Deterioration
I've seen patients who looked perfectly fine in the emergency department crash in the back of an ambulance. The common thread? Everyone assumed stability meant immobility. But physiology doesn't pause for transport.
The problem is that we're trained to look for obvious signs—gasping, cyanosis, hypotension. And a slight increase in respiratory rate. But subtle changes happen first. A drop in end-tidal CO2. These are early warning signs that something's shifting internally.
Over-Relying on Chest X-rays
CXR changes don't happen instantly, but pneumothorax progression does. In practice, a patient can go from 15% to 50% pneumothorax while the film still shows what looks like the same size collection. Trust your physical exam and vital signs more than the radiology report.
Ignoring the Opposing Lung
Ignoring the Opposing Lung
When we focus relentlessly on the collapsed side, we often lose sight of the lung that’s still trying to do its job. The “good” lung can become a silent victim of transport‑related stress, especially in patients who are already compromised.
What goes wrong?
- Compromised ventilation‑perfusion matching: The healthy lung may be forced to work harder, leading to over‑inflation and increased dead space. This can manifest as a subtle rise in respiratory rate, a drop in pulse oximetry that doesn’t fully correlate with the visible pneumothorax size, or a gradual decline in end‑tidal CO₂.
- Development of tension physiology: Even a modest shift in mediastinal structures can impede venous return from the “good” lung’s pulmonary veins, creating a cascade that mimics or accelerates a tension pneumothorax on the opposite side.
- Delayed recognition of bilateral involvement: In trauma patients, a contralateral pneumothorax can be missed because the initial CXR only shows one side. During transport, the second lung may collapse, turning a manageable unilateral problem into a life‑threatening emergency.
How to protect the opposite lung during transport?
- Maintain adequate ventilation settings: Use volume‑controlled ventilation with a modest tidal volume (6–8 mL/kg) and set the inspiratory pressure to avoid excessive over‑inflation of the healthy lung. If the patient is breathing spontaneously, provide supplemental oxygen at 2–4 L/min and consider a low‑flow CPAP (5–10 cm H₂O) to keep both lungs partially inflated.
- Monitor lung compliance and pressure waveforms: A sudden drop in compliance on the side with the chest tube often signals that the opposite lung is bearing the brunt of the work. Watch for “auto‑PEEP” on the ventilator circuit, which can be a sign of trapped air in the healthy lung.
- Use a chest tube on the affected side with water‑seal and suction: Proper water‑seal drainage equalizes pressure between the pleural space and the atmosphere, reducing the risk that the opposite lung will be squeezed during positive‑pressure ventilation.
- Consider a “dual‑lumen” approach when appropriate: In select cases (e.g., massive hemothorax with concurrent contralateral contusion), placing a small chest tube or catheter on the opposite side can act as a safety valve, preventing unexpected tension physiology.
Red flags to watch for:
- Sudden increase in peak airway pressures without a change in tidal volume.
- New‑onset hypoxemia (SpO₂ < 92% on FiO₂ = 0.5) that isn’t explained by the original pneumothorax size.
- Unexplained tachycardia or hypertension, especially when the patient appears otherwise stable.
Closing Thoughts
Transporting a patient with a pneumothorax is a delicate dance between maintaining oxygenation, preventing further lung collapse, and delivering clear, actionable information to the receiving team. The biggest pitfalls aren’t always the dramatic ones—they’re the subtle oversights: underestimating how quickly a stable‑looking patient can deteriorate, over‑relying on a static imaging study, and neglecting the health of the opposite lung Worth knowing..
By mastering the fundamentals—secure positioning, meticulous tube management, continuous physiologic monitoring, and precise communication—you turn a potentially precarious journey into a controlled handoff. Remember, the goal isn’t just to get the patient to the hospital; it’s to ensure they arrive in the same—or better—condition than when they left the emergency department Worth keeping that in mind. Surprisingly effective..
In short: Stay vigilant, trust your clinical judgment over any single data point, and always keep the whole patient in view. A well‑executed transport can be the difference between a routine transfer and a life‑saving intervention waiting to happen Less friction, more output..
