Treatment with vasopressors, fluids, and nursing interventions depends on accurate measurements. Because pressure transducers are hydrostatic, even small levelling errors can produce clinically relevant deviations (approximately 1 mmHg per 1.3 cm of vertical misplacement). Such errors may contribute to inappropriate therapy, for example under-recognition of hypotension, unnecessary vasopressor escalation, or missed venous congestion.\n\nThis prospective, multicenter, blinded observational study will quantify transducer levelling deviations during routine ICU care and evaluate whether clinically relevant deviations are associated with treatment decisions. Adult mechanically ventilated ICU patients with an arterial catheter, a central venous catheter, and ongoing vasopressor therapy will be included at hospitals in Västra Götalandsregionen, Sweden. Two blinded reference lines\u002Fsensors will be placed at predefined physiological zero levels for MAP and CVP and connected in parallel to the patient monitoring system. Continuous deviation (mmHg) between the clinical transducer position and the blinded reference level will be recorded for 8 hours while clinical staff remain unaware of the reference setup. MAP\u002FCVP-related treatment decisions (e.g., vasopressor adjustments, fluid therapy, and nursing interventions) will be recorded with timestamps.\n\nThe study will provide real-world data on the magnitude and frequency of invasive pressure transducer misalignment in daily ICU practice and its potential relationship to patient management.",[43,44],"Critically Ill","Haemodynamic Instability",[46,47,48,49,50,51,52,53,54],"Invasive arterial blood pressure monitoring","Central venous pressure monitoring","Pressure transducer leveling","Pressure transducer positioning","Intensive care unit","Critically ill","Patient safety","Mean arterial pressure","Right atrial pressure","NOT_YET_RECRUITING","2026-01-04",{"date":58,"type":59},"2026-01-09","ACTUAL",{"date":61,"type":39},"2026-02-01",{"date":63,"type":39},"2027-02-01",{"name":5,"class":6}]
