Changes in intrathoracic impedance from a pneumothorax: insights from an implanted monitoring system.
Timperley J., Mitchell AR., Brown P., Betts TR.
The measurement of transthoracic impedance is now possible using new implantable cardioverter-defibrillators. This can be used to monitor fall in impedance associated with increasing pulmonary oedema. We describe a case of a large rapid increase of impedance and dyspnoea related to a pneumothorax.
