Prev	A.34.17.4 Body Position Waveform IOD Constraints	Next

For channels encoding the patient's position as fixed values Waveform Data (5400,1010) shall only contain defined values listed in Table A.34.17-2.

Table A.34.17-2. Defined Body Position Data Values

Value	Meaning
0x00	supine
0x01	left lateral decubitus
0x02	prone
0x03	right lateral decubitus
0x04	upright
0xff	undefined

Note

With 8-bit Waveform Data and a single channel there may be an odd number of samples; see PS3.5 for encoding rules.

For channels encoding the patient's rotation and elevation, angles are stored in Waveform data (5400,1010). Units of measure (Channel Sensitivity Units (003A,0211) ) shall be degrees. Both angles having the value 0° is body position supine. Table A.34.17-3 shows the angle values of selected body positions.

Table A.34.17-3. Selected Body Position Angles

Position Value	Value in Channel I	Value in Channel 2
supine	0	0
lateral decubitus left	90	0
prone	180	0
lateral decubitus right	270	0
upright	0	90
feet up	0	-90
