Figure 2From: The effects of the semirecumbent position on hemodynamic status in patients on invasive mechanical ventilation: prospective randomized multivariable analysisEffect or norepinephrine on mean arterial pressure; P = 0.012. Despite the high variability, there is an clear tendence to lower MAP by higher dose of norepinephrine. This effect is significantly stronger in the 45° position then in the full horizontal position; norepinephrine and its interaction with HBE, P = 0.005. HBE: head of bed elevation; MAP: mean arterial pressure.Back to article page
