AB BACKGROUND: Dual-patient, single-ventilator protocols (ie, protocols to ventilate 2 patients with a single conventional ventilator) may be required in times of crisis. This study demonstrates a means to titrate peak inspiratory pressure (PIP), PEEP, and for test lungs ventilated via a dual-patient, single-ventilator circuit.METHODS: This prospective observational study was conducted using a ventilator connected to 2 test lungs. Changes in PIP, PEEP, and were made to the experimental lung, while no changes were made to the control lung. Measurements were obtained simultaneously from each test lung. PIP was titrated using 3D-printed resistors added to the inspiratory circuit. PEEP was titrated using expiratory circuit tubing with an attached manual PEEP valve. was titrated by using a splitter added to the ventilator tubing.RESULTS: PIP, PEEP, and were reliably and incrementally titratable in the experimental lung, with some notable but manageable changes in pressure and documented in the control lung during these titrations. Similar results were measured in lungs with identical and different compliances.CONCLUSIONS: Pressures and can be reliably adjusted when utilizing a dual-patient, single-ventilator circuit with simple, low-cost modifications to the circuit. This innovation could potentially be lifesaving in a resource-limited or crisis setting. Understanding the interactions of these circuits is imperative for making their use safer.
