Energy Expenditure & Body Positioning
Energy expenditure
The Cardio is an ideal device for measuring energy expenditure in free living for short periods of time. As can be seen from the screen shot below, the following parameters are provided:
| RMR: | Resting metabolic rate |
| AEE: | Activity Energy Expenditure |
| TEE: | Total Energy Expenditure |
Please note: the Cardio only allows short term recording of up to 31 hours. For longer term energy expenditure monitoring of up to 21 days please see the Actiheart page.
It is possible to import the data from an Actiwave Cardio recording into the Actiheart software for more advanced manipulation of the energy expenditure data. This is an advanced function; please contact us for further details.
Body position
The Cardio has a tri-axial accelerometer data from which can be used to display body position. This can be useful in examining sleep disorders such as Obstructive Sleep Apnoea (OSA) which can be exacerbated by lying supine. The data viewer below shows the output available from the accelerometer:
