Non-invasive ventilator RA

medicalelectronichigh-flow nasal cannula

Overview
The RA series non‑invasive ventilator integrates multiple ventilation modes and core monitoring functions to enable refined ventilatory management. It supports high‑ and low‑pressure oxygen sources and is suitable for various clinical environments and deployment at bedside or on wheelchairs. An independent external humidifier ensures airway humidification and improves patient comfort. Preset therapy plans enable rapid initiation to save clinical time.

Main features and highlights

• Single device adaptable to multiple ventilation scenarios, compatible with adult and paediatric patients
• Support for high‑ and low‑pressure oxygen sources with one‑touch oxygen boost to rapidly increase FiO2
• Preset therapy plans for quick startup and reduced setup time
• Integrated 7 non‑invasive ventilation (NIV) modes and support for high‑flow oxygen therapy (HFOT) to meet diverse clinical needs
• Independent external humidifier to maintain airway moisture and patient comfort
• Data export and management: real‑time log viewing, USB data export, and integration capability with nurse‑station monitoring systems

Operation and alarm design
The device features an optimized user interface that allows fast parameter setup without obscuring waveforms. Clear alarm logic and dual alarm‑pause keys facilitate clinical recognition and response.

Intelligent ventilation control

• Target tidal volume control (SVAPS): dynamically adjusts inspiratory pressure to stabilize PaCO2 and simplify titration
• Proportional pressure support (PPS): provides real‑time feedback based on patient respiratory effort to improve synchrony and tolerance

Monitoring indices to assist therapeutic decisions
The device supports clinical assessment indices to aid decision‑making:

• VOX = SpO2 / (FiO2 × VT) — for early identification of hypoventilating patients and timely intervention
• ROX = (SpO2 / FiO2) / respiratory rate (RR) — for evaluating HFOT effectiveness and optimizing therapy choice

Applicable scenarios
Multi‑level hospital wards, bedside monitoring, wheelchair‑mounted use and other settings requiring non‑invasive ventilation or high‑flow oxygen therapy.
