Increasing mA beyond initial electrical capture threshold

Question #: 480

Question:


In the procedure of TCP, upon electrical capture do you add 10 milli amps even if you have mechanical capture with signs of perfusion

Answer:


During transcutaneous pacing procedure, upon electrical and mechanical capture, it is recommended to increase the milliamps (mA) 10% higher than the threshold of initial electrical capture as a safety margin (usually 5-10 mA). When using external transcutaneous pacing, the conduction can fade with time; the pacer can stop working. Increasing energy can assist mitigating that risk. Transcutaneous pacing can be uncomfortable for a patient. Sedation and analgesia can be considered when consulting a Base Hospital Physician to tailor the management plan to the patient.
