Mean arterial pressure and mean perfusion pressure deficit in septic acute kidney injury.

Background: Changes in mean perfusion pressure (MPP) from premorbid resting values may contribute to the progression of septic acute kidney injury (AKI).

Objectives: In patients with septic shock, we aimed to investigate the association of changes from premorbid values with AKI severity and progression.

Methods: We obtained premorbid resting mean arterial pressure (MAP), central venous pressure (CVP), and MPP, and then recorded data from intensive care unit admission 2 hourly for the first 24 hours to calculate hemodynamic deficits.

Invasive blood pressure recording comparing nursing charts with an electronic monitor: a technical report.

Background: Blood pressure management (assessed using nursing charts) in the early phase of septic shock may have an effect on renal outcomes. Assessment of mean arterial pressure (MAP) values as recorded on nursing charts may be inaccurate.

Aim: To determine the difference between hourly blood pressure values as recorded on the nursing charts and hourly average blood pressure values over the corresponding period obtained electronically from the bedside monitor.
