Indications for Use
The SAVe II™ series are intended to provide short-term ventilatory support to adults during CPR or when Positive-Pressure Ventilation (PPV) is required to manage Acute Respiratory Failure (ARF). The SAVe II™ series are appropriate for adults that weigh at least 45 kg. It is intended to be used in pre-hospital, field hospitals, and transport environments.
Device Story
The SAVe II™ and SAVe II™ Basic are portable, battery-powered emergency ventilators designed for use by first responders in pre-hospital, field hospital, and transport settings. The device uses an internal compressor to deliver volume-targeted, time-cycled, pressure-limited breaths using ambient air or supplemental oxygen. It features an active breathing valve and connects to patients via face mask, supraglottic airway, endotracheal tube, or tracheostomy tube. The device is software-controlled, with settings based on patient height (SAVe II™ allows user adjustment; SAVe II™ Basic has fixed parameters). It monitors airway pressure and provides visual alarms for circuit disconnect, over-pressure, low battery, and high temperature. The device aims to augment manual BVM ventilation, providing automated, controlled positive pressure to improve patient outcomes in emergency scenarios where compressed oxygen may be unavailable.
Clinical Evidence

### Device Description:
The SAVe II™ and SAVe II™ Basic ventilators are battery powered compressors to deliver automated, controlled positive pressure breaths with ambient air for up to 10 hours. It is designed to augment the capabilities of first responders by supplementing Bag Valve Mask (BVM) manual ventilation delivery with an automated solution that can be rapidly deployed by minimally skilled providers in environments where compressed oxygen is unavailable or ill-advised.
To support use in emergency situations, the SA Ve II™ is portable and easy to carry. Rapid initial setup is enabled by default ventilator settings based on adult patient's height, ranging from 4'6'' to 6'6" weighing at least 45 kg, organized in a circular-shaped graphic. To mitigate the risk of patient injury, airway pressure is monitored and users are alerted to potentially dangerous low and high pressure situations. Immediate patient injury due to high pressure is avoided by a pressure cut-off that triggers an exhalation if inspiratory pressure exceeds device settings. Rapid troubleshooting is enabled by visual alarm indicators located together at the bottom of the unit that identifies the most likely cause of the triggered alarm.

### Substantial Equivalence Discussion - SAVe IITM
Table 2 compares the SAVe II™ vs. the predicate Impact Model 754 (K931473). One will note that the predicate has more features than the proposed SA Ve II™ and thus one could consider it a subset of the predicate.
It should be noted that our legacy SAVe™ ventilator (K071221) has many of the equivalent function and features of the SAVe IJ™. The legacy SAVe™ used the Impact Model 754 (K931473) as its predicate when it was reviewed and found substantially equivalent.
In addition, we have included in Table 2 a reference predicate, the SA Ve™ ventilator (K071221).
