It was reported that during intra-aortic balloon (iab) therapy with a fiber optic catheter that the patient went into full code with loss of the optical sensor and electrocardiogram (ecg) signal.
An optical sensor failure alarm was generated.
There could have been a possible fiber optic break in the catheter due to cpr(cardiopulmonary resuscitation).
There was an attempt to establish blood pressure signal via central lumen, but the customer was having trouble finding the cable.
An ecg signal was present, but poor.
The emergency service specialist informed the customer to switch to a semi-auto mode and attempt to find a lead that could be seen.
There was a weak signal established in avr(augmented vector right) but not strong enough for pump to pick-up r waves.
Finally the customer was able to get the cable and hooked up to the transducer.
The patient proceeded to code again.
After zeroing, the customer was able to get a pressure signal from cpr effort and pump began working.
The emergency service specialist verified that the customer had cables on each pump for pressure transducer.
The patient expired due to underlying disease, but the death was not attributed to the device by the facility.
The date of death is unknown.
