Datex-Ohmeda 1504-3623-000 Regulator GE 1503-3004-000 Regulator 172 KPA  for Aestiva 7900 ventilator

The Datex Ohmeda 1504-3623-000 / 1503-3004-000 Regulator is a precision-engineered pneumatic pressure control module specifically designed for the Datex-Ohmeda Aestiva 7900 anesthesia ventilator and workstation series. This critical OEM component serves as the primary gas pressure regulation interface within the machine's pneumatic delivery system, ensuring stable and accurate reduction of high-pressure pipeline or cylinder gas supplies to safe, consistent working pressures for flowmeters, vaporizers, and the ventilator drive circuit. Manufactured to stringent medical device standards by Datex-Ohmeda (GE Healthcare), the regulator features robust brass or stainless steel construction with medical-grade sealing elements that resist degradation from prolonged exposure to medical gases and cleaning agents. As a direct replacement part, the 1504-3623-000/1503-3004-000 assembly guarantees seamless integration with the Aestiva 7900's gas distribution manifold, maintaining precise pressure differentials essential for accurate tidal volume delivery, reliable alarm functionality, and consistent agent concentration throughout complex surgical procedures.

Description of ventilator parts: 

This essential pneumatic component is extensively deployed in operating rooms, ambulatory surgery centers, ICU transition units, and trauma centers utilizing the Datex-Ohmeda Aestiva 7900 anesthesia platform. The regulator is primarily utilized during anesthesia induction and maintenance phases, where precise gas pressure stabilization is critical for accurate fresh gas flow delivery and ventilator synchronization. Anesthesiologists and CRNAs rely on this module to maintain consistent working pressure that enables reliable flowmeter calibration, stable vaporizer output, and accurate tidal volume compensation across diverse ventilation modes. Biomedical engineering technicians integrate the regulator into scheduled preventive maintenance (PM) protocols, performing pressure verification and leak testing to uphold manufacturer performance specifications. The assembly's robust design supports continuous operation in high-acuity surgical environments, ensuring uninterrupted gas delivery for adult, pediatric, and neonatal patients requiring mechanical ventilation support.

Advantage:

OEM Precision Calibration: Factory-calibrated to exact Datex-Ohmeda specifications, the regulator delivers consistent pressure reduction without frequent field adjustments, reducing maintenance downtime and ensuring reliable clinical data throughout its service life.

Medical-Grade Durability: Constructed with corrosion-resistant alloys and biocompatible seals, the assembly withstands rigorous clinical environments, repeated sterilization cycles, and prolonged exposure to volatile agents without performance degradation.

Seamless System Integration: Designed as a direct plug-and-play replacement for the Aestiva 7900 pneumatic manifold, the regulator requires no software modifications or hardware adapters, ensuring immediate compatibility with existing gas delivery algorithms.

Enhanced Patient Safety: Accurate pressure regulation prevents over-pressurization of downstream components, protecting sensitive flow sensors, vaporizers, and breathing circuits from damage while maintaining stable concentrations.

Cost-Effective Maintenance: As a field-replaceable module, the regulator enables targeted replacement of worn pressure control elements without requiring full gas manifold assembly replacement, reducing repair costs and equipment downtime.
