Hi Malgorzata,

since a while (2 years) we are successfully using an MRI compatible
Respiration Transducer (Part No. TSD221-MRI) from Biopac Systems (
www.biopac.com) during our MEG recordings.
So far we did not experience any interference with the MEG signals.

In order to operate and control the device you will have to purchase
some more equipment (amplifiers, tubing, cabels etc.) from Biopac which
enables the recording of (further) peripheral signals (ECG, EDA etc.). 
At least at the CTF 275 channel system (VSM Omega 2005 with the DSQ-
3500 electronic) the analogue signals are easy to feed into the system
(via AD-inputs) in order to have simultaneous MEG/EEG recordings
together with the peripheral signals provided by the Biopac electronic.

If you have further questions feel free to contact me again.

Best, Andreas
