Here, we propose a circuit design that allows a health care provider to individualize and independently adjust the inspiratory pressures, PEEPs and tidal volumes delivered to multiple patients who are sharing a single ventilator. This method relies upon currently available and mass-produced parts, that require no special expertise for assembly. The PReVentS ventilator splitting circuit allows for patient management using the well-established and familiar principles of pressure-controlled ventilation. The PReVentS method could allow for improved care of multiple patients having different disease courses, who are forced to share the same ventilator if no better option exists.
