Purpose: In intensive care patients, position changes are aimed at the mobilization of secretions in the air, the prevention of pressure ulcers and the reduction of the risk of pneumonia associated with the ventilator. We aimed at researching the effects of the rear (supin), left lateral, right lateral and Fowler positions on respiratory and cardiovascular parameters with the non-invasive cardiovascular output monitor using the CO2 re-inhalation technique. Tools and Methods: 40 patients between the ages of 18 and 65 under the invasive mechanical ventilator support, followed in intensive care for over 24 hours, were included in the study. Patients were monitored with a non-invasive heart rate monitor in the rear, left side, right side and Fowler position, respectively. The respiratory and hemodynamic parameters of patients were measured in an hour interval in these positions. Results: A significant difference was found between the measurements when compared the average arterial pressure values measured at different times in the left side position. There was a significant difference between the SpO2 values measured at different times in the rear positions. However, this difference was not clinically meaningful. There was no significant difference between the groups in terms of other respiratory and heart parameters measured at different times. In patients with the support of a mechanical ventilator with hemodynamics stable, we have seen that position changes do not lead to clinically significant changes in respiratory mechanics, hemodynamic parameters and oxygenation.
