…specialist investigations. Both fail more often for practical than for medical reasons: the cuff is in the wrong place, the electrodes come off, the patient…
…adult recommendations. Electrode pads should be positioned as standard, and defibrillation energy levels should remain consistent with those used for non pregnant adults. The fetus…
