Title: [abstract] HYPERBARIC OXYGEN IN PATIENTS WITH IMPLANTED CARDIAC DEFIBRILLATORS AND PACEMAKERS
Author: Schmitz, S; Churchill, S; Weaver, LK
Abstract: BACKGROUND: Patients with implantable cardioverter defibrillators (ICD) or pacemakers may need hyperbaric oxygen (HBO2) therapy. These devices may not be suitable for pressurization or may expose the patient to increased risk during HBOMETHODS: Survey of ICD and cardiac pacemaker manufacturers to determine which devices were approved for HBORESULTS:INSERT TABLE FROM PICTURESome ICD and pacer devices have been tested/approved for HBO2 exposures. We could find no in vivo ICD testing in hyperbaric conditions. Titanium pacemakers/ICDs will deform at 5 atm abs. Some pacing rates can be affected by sudden changes in pressure. Faulty ICDs and pacemakers, identified by recalls, may increase patient risk during HBO2. If ICD leads are damaged, ignition could occur if the ICD discharges (personal communication with Medtronics, 2005). It is unknown if ignition could cause patient combustion. CONCLUSIONS: 1) Approved pressures are up to 8.0 atm abs for pacemakers and 4.9 atm abs for ICDs, but vary by manufacturer and model. 2) ICD defibrillation during HBO2 has not been reported, nor tested. 3) If there is an ICD discharge (defibrillation) in the presence of lead damage, ignition could occur. We advise that present-day ICDs should be deactivated before HBO2 therapy (monitoring the patient and the capability for defibrillation would therefore be important).
