Background
The ResMed Astral 150 is a portable life-support ventilator released in 2014 as an upgrade to ResMed’s earlier portable ventilation systems. Designed for patients requiring invasive or non-invasive mechanical ventilation, the Astral 150 is a compact, lightweight device used in both clinical and home-care settings.
This model improved upon previous ResMed ventilators with a 30% smaller design, extended 11-hour battery life, and Bluetooth connectivity for remote monitoring. Key features include a 5.5-inch touchscreen interface, multiple ventilation modes (CPAP, BiPAP, and pressure/volume control), and compatibility with the RT210 humidifier. The Astral 150 supports adult and pediatric patients with respiratory conditions like COPD, ALS, or respiratory failure.
The ventilator was FDA-cleared (K133868) for safety and efficacy and remained a flagship portable ventilator until succeeded by newer ResMed models in the late 2010s.
Identification
The ResMed Astral 150 can be identified by its model number AST150 clearly displayed on the device label, with specific variants like AST150-01 indicating regional versions. This portable ventilator features a compact blue housing with an integrated carrying handle and distinctive 5.5-inch touchscreen interface. The FDA clearance documentation (K133868) confirms its 2014 release with Class II medical device classification, while ResMed's official specifications note its compatibility with the RT210 humidifier system. Unlike earlier models, the Astral 150 offers extended battery operation and Bluetooth connectivity for clinical monitoring, as noted in both ResMed's support materials and Lincare's device overview. The unit's regulatory markings and serial numbers are typically located on the rear panel near the power input.
