Chest Drain (ICD) Care
A chest drain can look alarming, but the rules for living with it safely are simple: keep the container upright and below your chest, never clamp or lift it unless told, and pay attention to your breathing.
In an emergency — act now
What it is
A chest drain (also called an intercostal drain or ICD) is a tube placed through the chest wall into the space around the lung. It connects to a sealed container that lets trapped air, fluid or blood drain out, while a water seal stops anything flowing back in.
Why you have it
It removes air (a collapsed lung, or pneumothorax), fluid, blood or infection from around the lung so the lung can re-expand and work properly. It usually stays in until that space is clear.
Day-to-day care
- Always keep the container upright and below the level of your chest — on the floor by the chair or bed, or carried low when you walk. This keeps the water seal working and lets gravity drain the space.
- Don't clamp the tube when moving around. The drain is meant to stay open; clamping is only ever done on a clinician's instruction.
- Keep the tubing free of kinks and loops. A loop of tubing full of fluid can stall the drain — let it run in a gentle, straight line down to the container.
- Watch the fluid level move ("swinging") as you breathe. That gentle rise and fall shows the drain is working and connected.
- Note any bubbling. Bubbles in the water seal usually mean air is still leaving the chest, which can be expected early on. Your team will tell you what's normal for you.
- Move and walk as encouraged, carrying the container below your chest. Gentle movement helps the lung re-expand — just protect the tube where it enters the skin from being tugged.
- Keep the dressing at the tube site clean and dry, and don't pull on the stitch or tube.
- Bubbling that suddenly increases, or appears when it had stopped, is worth reporting.
- Swinging that stops completely may mean the lung has re-expanded — or that the tube is blocked or kinked. Let your team know either way.
When to call your team
- You become more breathless or develop chest pain — if it's sudden or severe, treat it as the emergency above.
- The drainage suddenly increases, or turns bright red (fresh blood).
- The tube is pulled partly out, the dressing comes loose, or the stitch gives way.
- The site becomes red, swollen, hot, painful or leaks fluid — signs of infection — or you develop a fever.
- The fluid stops swinging and you're not sure why, or the container is full.
Frequently asked questions
Why must the container stay below my chest?
The drain works by gravity and a water seal. Lifting the container above your chest can let fluid or air flow back toward the lung. Keeping it low — on the floor or carried at your side — keeps drainage one-way and safe.
Is bubbling in the container good or bad?
It depends. Early on, bubbling often means trapped air is leaving the chest — the drain doing its job. What matters is the trend: bubbling that newly appears, or suddenly increases, should be reported to your team.
Can I sleep and move around with it?
Yes. Keep the container upright and below chest level beside your bed, and avoid lying on the tube or kinking it. Walking is encouraged to help the lung expand — just carry the container low and protect the tube.
What happens when it's ready to come out?
Once the air leak or fluid has settled and your lung has re-expanded (confirmed on an X-ray), your team removes the tube at the bedside. It's quick, and the small wound is closed with a stitch or dressing.
