About Us
There are several main designs of chest drainage systems, each tailored to specific clinical needs:
1. Single‑chamber (open) systems
This simplest form consists of a collection jar only. Fluid or air from the pleural space drains directly into the chamber, but there is no built‑in water seal or suction control. Open systems are rarely used today because they offer no protection against back‑flow, increasing the risk of inadvertent pneumothorax.
2. Two‑chamber (water‑seal) systems
Building on the single‑chamber design, these incorporate a second chamber filled with sterile water to form a one‑way valve. Air or fluid enters the collection chamber, then passes through the water seal, which prevents retrograde air entry. They may operate by gravity alone and require careful monitoring of the water level to maintain an effective seal.
3. Three‑chamber (traditional) systems
The most common bedside unit adds a third, suction control chamber. The first chamber collects effluent; the second serves as the water‑seal valve; and the third regulates negative pressure, either via regulated wall suction or “dry” control mechanisms. This design offers more precise suction levels (typically –10 to –20 cm H₂O) and reliable water‑seal function, making it ideal for most postoperative and trauma patients.
4. Digital (electronic) chest drainage systems
Modern “dry” systems replace water columns with electronic sensors and pumps. They automatically adjust and display precise intrapleural pressure, track real‑time air leaks, and store data for trend analysis. Lightweight and portable, digital units enhance patient mobility and improve accuracy over manual water‑seal measurements.
Choosing among these options depends on clinical indication, required suction control precision, monitoring capabilities, and patient mobility needs. Proper selection and vigilant management of the chosen system are essential to ensure effective drainage, prevent complications, and promote lung re‑expansion.
