ResMed Astral 150 Portable Ventilator (With Internal Battery)

The ResMed Astral 150 is a high-performance, portable life-support ventilator designed for patients with chronic respiratory failure. It bridges the gap between intensive care unit (ICU) ventilators and home care, offering hospital-grade capabilities in a compact, mobile platform. It is intended for use by trained clinicians and patients/caregivers under strict medical supervision.

Key Features & Specifications

1. Advanced Ventilation Modes:

   • Invasive & Non-Invasive Support: Can be used with a tracheostomy tube (invasive) or with masks (non-invasive NIV/CPAP).

   • Modes: Includes essential modes like Volume Control, Pressure Control, Pressure Support (PS/CPAP), and Assist Control (A/C). It also features automatic modes like AVAPS (Average Volume-Assured Pressure Support) and iVAPS (Intelligent Volume-Assured Pressure Support), which intelligently adjust pressure to ensure a consistent tidal volume.

2. Integrated Internal Battery & True Portability:

   • Long Battery Life: Features a high-capacity internal battery providing up to 8 hours of operation (depending on settings and patient circuit), making it ideal for trips, travel, and power outages.

   • Lightweight: Weighs approximately 3.2kg , including the battery.

3. Built-in Humidifier and Compressor:

   • Integrated Flow Generator: Has a built-in compressor, meaning it does not require an external gas source (like an oxygen cylinder) to function, though it can be connected to one for oxygen enrichment.

   • Heated Humidifier (Optional): A key feature for patient comfort and airway health during long-term ventilation, preventing dryness and complications. The heated humidifier is a slide-in module.

4. Intuitive User Interface:

   • Color Touchscreen: Provides clear visualization of waveforms, loops, and patient data.

   • Simple Dial: Allows for easy navigation and setting adjustments.

   • Clinician & Patient Locks: Prevents unauthorized or accidental changes to critical settings.

5. Comprehensive Monitoring and Alarms:

   • Displays: Shows real-time parameters including tidal volume, respiratory rate, minute ventilation, leak, and FiO2 (when connected to oxygen).

   • Safety Alarms: A comprehensive suite of visual and audible alarms for events like low minute ventilation, high respiratory rate, circuit disconnect, low battery, and high pressure.

6. Oxygen Capability:

   • Can be connected to an optional ResMed O � Conserving Module or an external oxygen source to deliver precise concentrations of oxygen (FiO �).

Benefits and Advantages

• Enables Life Outside the Hospital: Provides critically ill patients with the freedom to be discharged home and engage in community activities.

• Continuity of Care: Delivers ICU-level ventilation in the home, during transport, and in sub-acute care facilities.

• Patient-Ventilator Synchrony: Advanced algorithms reduce the work of breathing and improve comfort by responding effectively to the patient's own breathing efforts.

• Safety and Reliability: Built with redundant systems and robust alarms to ensure patient safety during mobile use.

• Simplifies Management: The intuitive interface and pre-set protocols help clinicians set up and manage therapy effectively.

• Weight: 3.2 kg (7.1 lbs), offering an impressive power-to-weight ratio for mobility.
• Dimensions (L x W x H): 285 mm x 215 mm x 93 mm (11.2 in x 8.5 in x 3.7 in).
• Sound power level: 43 ± 3 dBA, measured according to ISO 80601-2-12:2011.
• Sound pressure level: 35 ± 3 dBA, also measured according to ISO 80601-2-12:2011.
• Airline Friendly: Yes. 

• Internal battery: A Lithium-Ion battery (14.4 V, 6.6 Ah, 95 Wh) provides up to 8 hours of backup power.
• External battery (optional): Connect up to two external batteries for an additional 8 hours each, for a total of up to 16 hours of continuous portable power.
• Power supply: AC 100–240V, 50–60Hz, 2.2A. 

• Valve circuit therapy: Continuous Positive Airway Pressure (CPAP), Assisted Controlled Ventilation (ACV), Pressure Assisted Controlled Ventilation (PACV), Pressure Synchronized Intermittent Mandatory Ventilation (P-SIMV), Volume Synchronized Intermittent Mandatory Ventilation (V-SIMV), and Pressure Support (PS).
• Leak circuit therapy: CPAP, Spontaneous/Timed (S/T), Pressure Assisted Controlled (P(A)C), and intelligent Volume-Assured Pressure Support (iVAPS).
• Mouthpiece ventilation: Assisted Controlled Ventilation (A(C)V), Pressure Assisted Controlled Ventilation (P(A)CV), and Pressure Support/Synchronized Volume Targeted (PS/SVt).
• Special features: Manual breath and sigh breath options are also available.
