Maquet 6693752 Expiratory cassette Getinge 6693752 Servo U Exp Cassette Dark

The Maquet 6693752 Expiratory Cassette is the original equipment manufacturer (OEM) precision module that forms the core of the expiratory section in the Maquet / Getinge SERVO-U ventilator system. One expiratory cassette is delivered with each SERVO-U base unit, and the component integrates the ventilator's expiratory valve, exhaled gas flow measurement, and moisture management functions into a single removable, reprocessable assembly.

Engineered as a sealed precision instrument, the cassette locks securely into the patient unit's expiratory compartment, where its integrated sensing electronics communicate directly with the ventilator's control system through dedicated electrical connectors. During each breathing cycle, the cassette regulates the release of exhaled gas, maintains the prescribed PEEP level, and provides the accurate expiratory flow and volume data on which the SERVO-U's closed-loop ventilation modes depend.

Maquet documents the cassette as a complete unit that must not be disassembled in the field; it is designed for removal at the press of a button, followed by validated cleaning and disinfection between patients. When the cassette's internal operating-time counter approaches exhaustion—or after membrane wear affects valve performance—replacing the complete unit with the genuine 6693752 cassette restores the expiratory section to its factory-specified measurement and control accuracy.

• Maquet Servo U

The 6693752 expiratory cassette is applied within Maquet SERVO-U ventilators deployed across Intensive Care Units (ICU), Neonatal and Pediatric Intensive Care Units, Emergency Departments, Intermediate Care and Step-Down Units, and intra-hospital transport scenarios—wherever adult, pediatric, or infant patients receive invasive ventilation, non-invasive ventilation (NIV), or high-flow oxygen therapy.

As a core functional module of the patient unit, it is required for every ventilation mode the SERVO-U delivers, including volume control, pressure control, PRVC, pressure support, and NAVA-based modes.

The cassette is the essential spare part for hospital biomedical engineering departments and third-party service organizations maintaining SERVO-U fleets. It is replaced when the unit's operating-time limit is reached, when expiratory valve or flow measurement irregularities are detected, or when a cassette fails the ventilator's pre-use check. Its removable design also supports routine infection control workflows—the cassette is exchanged, cleaned, and disinfected per Maquet's reprocessing instructions between patients, making genuine spare cassettes indispensable for departments that must return ventilators to service quickly.
