ADS1298R: ADS1298R or similar for absolute and respiration impedance measurement

Part Number: ADS1298R
Other Parts Discussed in Thread: AFE4500

Hello,

I would like to know if a suitable chip exists to measure transthoracic impedance to achieve the next:

- Absolute transthoracic impedance measure must be precise. +/- 2 ohm once it has been calibrated. +/-2 ohm precision must be mantained under diferent temperatures (0º-50º)

- Resolution achieved in the transthoracic impedance measurement signal must be good enough to be able to distinguish the respiration of the patient (0,1ohm oscillations).

I know that ADS1298R is prepared to measure respiration, but I think it is not good enough when looking for precise absolute impedance measurement. Some help finding an appropiate device, which can be good for both absolute and relative transthoracic impedance measurement?
