Abstract: A device for calculating stroke volume using AI includes a filtering unit to filter an arterial blood pressure value and a stroke volume, among first data and second data including arterial blood pressure values and stroke volumes corresponding to the arterial blood pressure values, a pre-training unit to pre-train a first stroke volume calculation model which calculates a stroke volume based on the arterial blood pressure value, by using third data filtered from the first data, a transfer learning unit to transfer learn the first stroke volume calculation model which calculates a stroke volume based on the arterial blood pressure value, by using fourth data filtered from the second data, thus to generate a second stroke volume calculation model, and a stroke volume calculation unit to calculate a stroke volume corresponding to the input arterial blood pressure of a specific patient by using the second stroke volume calculation model.
