What type of chest tube system does this statement describe?

This chest drainage system has no water column to control suction but uses a suction monitor bellow that balances the wall suction. You can adjust suction pressure using the rotary suction dial on the side of the system. It allows for higher suction pressure levels, has no bubbling sounds, and water does not evaporate from it as with other systems.

A. Mediastinal chest tube system
B. Dry suction chest tube system
C. Wet suction chest tube system
D. Dry-Wet suction chest tube system

Answer :

Final answer:

The system described is a Dry suction chest tube system, which uses a suction monitor bellow and allows adjustment via a rotary dial, avoiding water evaporation and noise from bubbling.

Explanation:

The chest tube system described in the question is a Dry suction chest tube system. This system uses a suction monitor bellow to balance the suction pressure instead of relying on a water column like traditional wet suction systems.

The respiratory function of the chest cavity is at play here, where negative pressure is essential to keep the lungs inflated. The purpose of applying suction to the chest cavity in medical patients, particularly after surgery or trauma, is to reestablish this negative pressure that keeps the lungs from collapsing, which can occur from loss of adhesion due to air entry in the chest cavity or lack of suction because of system malfunction.

The dry suction chest tube system allows the medical practitioner to adjust the suction pressure using a rotary suction dial without the need for water - thus preventing evaporation and eliminating the bubbling sound characteristic of wet systems.
