Aim: The aim of this study was to examine the effect of different bed-head angles given to patients lying in the supine position in an intensive care unit on the haemodynamic parameters of central venous pressure, systolic and diastolic blood pressure, heart rate, breathing rate and peripheral oxygen saturation.
Methods: The study was conducted with 50 intensive care patients aged 18 and over in a general surgery intensive care unit in Turkey. With each patient in the supine position, the bed-head was raised to an angle of 0, 20, 30 and 45 degrees without a pillow, and the haemodynamic parameters of central venous pressure, systolic and diastolic blood pressure, heart rate, breathing rate and peripheral oxygen saturation were recorded after 0 and 10 minutes.

Aim: The aim of this study was to examine the effect of different bed-head angles given to patients lying in the supine position in an intensive care unit on the haemodynamic parameters of central venous pressure, systolic and diastolic blood pressure, heart rate, breathing rate and peripheral oxygen saturation.
Design: This was a non-randomised quasi-experimental repeated measures study. Settings: The study was conducted with 50 intensive care patients aged 18 and over in a general surgery intensive care unit in Turkey.
Methods: With each patient in the supine position, the bed-head was raised to an angle of 0, 20, 30 and 45 degrees without a pillow, and the haemodynamic parameters of central venous pressure, systolic and diastolic blood pressure, heart rate, breathing rate and peripheral oxygen saturation were recorded after 0 and 10 minutes. The data obtained was evaluated using the Mann-Whitney test, the Kruskal Wallis test and the Bonferroni test.

Experimental: the different bed-head angles in the supine position
The researcher brought the patient to the supine position with the bed-head at 0 degree, and immediately (minute 0) made haemodynamic measurements: central venous pressure, systolic and diastolic blood pressure, heart rate, breathing rate and peripheral oxygen saturation. It was taken into account that this could change haemodynamic parameters, and immediately after a 10-minute period of rest, the same haemodynamic measurements were repeated. After this, the bed-head was adjusted to an angle of 20 degree, and the same procedure was repeated, with measurements after 0 and 10 minutes. The same procedure was followed with the bed-head raised to 30 degree and then to 45 degree. In positioning the patients' bed-heads to different angles, a spirit level and a protractor were used.
