The Baxter Ventilator was designed specifically to address a shortage of ventilators during the COVID-19 pandemic.

The ventilator provides volume control continuous mandatory ventilation (VC-CMV). The tidal volume, respiratory rate, inspiratory to expiratory time (I/E), positive end expiratory pressure (PEEP), and fraction of inspired oxygen (FiO2) can all be set on a touch screen or through manual controls. For the patient's safety, the maximum Peak Inspiratory Pressure (PIP) will not exceed 40 cm of ...

The ventilator provides volume control continuous mandatory ventilation (VC-CMV). The tidal volume, respiratory rate, inspiratory to expiratory time (I/E), positive end expiratory pressure (PEEP), and fraction of inspired oxygen (FiO2) can all be set on a touch screen or through manual controls. For the patient's safety, the maximum Peak Inspiratory Pressure (PIP) will not exceed 40 cm of water. To allow for use in field hospitals, the ventilator can use ambient air, high or low pressure oxygen. When evaluated on a Gaumard HAL S3201 simulator, the prototype met the target criteria and produced results similar to industry-standard ventilators.

In a pandemic mass production and supply chains for ventilators may be disrupted, while surges in demand for medical device components and market failures may limit availability. The Baxter Ventilator was therefore designed to be built by individuals with limited skills in distributed locations, as well as at scale. A single person can assemble a ventilator a day with an only an Allen set and crescent wrench following Ikea type assembly instructions and videos. Using readily available industrial COTs components costing only $1,500, the ventilators are not dependent on specialized equipment or parts and are cost-effective. The design features tried and true mechanisms for long life cycles in harsh environments.

The Baxter Ventilator also provides a robust platform for expanded capabilities. Additional sensors and controls are currently being added to the Baxter ventilator to allow features like pressure control continuous mandatory ventilation (PC-CMV) and pressure-support ventilation (PSV).
