      • 1.
        1. Ten percent of 150 patients undergoing continuous on-line monitoring of respiratory parameters while on respirator therapy sustained serious respiratory difficulties which were not easily apparent from clinical signs alone.
      • 2.
        2. Half of these respiratory difficulties resulted in serious cardiac arrhythmia.
      • 3.
        3. In most cases, the connection of the cardiac arrhythmia with previous respiratory difficulty was understood only because of the availability of the recorded measurements.
      • 4.
        4. Frequent respiratory gas analysis and the consequent improvement in respiratory management can make a significant difference in prevention of “unexpected” cardiac arrhythmias.
