Bland Altman graphs showing differences of means between the breath hold and free breathing methods on the y-axis and the mean of both methods on the x-axis in ml in the right ventricular end diastolic volume (RVEDV) and left ventricular end diastolic volume (LVEDV). In the consciously examined group the upper and lower limits of agreement of LVEDV: 17.9 ml and -21.6 ml, RVEDV: 23.8 ml and -29 ml. In the intubated examined group the upper and lower of agreement of LVEDV: 4.7 ml and -5.5 ml, RVEDV: 5.7 ml and -4.6 ml.
