FAQs - Thumper® and 2005 AHA CPR Guidelines
 
Q. Can you upgrade my Thumper® to have it meet the 2005 AHA CPR Guidelines?
A.  It depends on the model of Thumper you have:
 
  Model 1004.  No, they have been out of production for over 20 years. 
 
  Model 1005.  The Model 1005 has a ventilation switch.  The ventilator can be turned off and the unit will do continuous compressions.  However, the compression rate is set at 80 compressions/min.  However, the Model 1005 can be adjusted to 100 compressions/min.  See Maintenance Instructions in the 1005 Manual or contact MII for further instruction. 
 
  Model 1007.  Yes.  There is a $480 USD conversion that adds a switch so that the Thumper will provide a continuous 100 per/min compression rate.  The modified Thumper can be used in the 30:2 or continuous compression protocol by the use of external ventilation.  Note:  for the 30:2 protocol the continuous compressions are interrupted so that external ventilation can be delivered.  Compressions are then resumed.   See  demonstration video.  Contact us for further information.
  NOTE:  Download of the video will take approximately 3-5 minutes (based on a 1.3 mb download DSL connection).

Q. How do the 5:1 and 30:2 compression to ventilation (C:V) ratios compare?
A.  See the timing diagrams below comparing the 5:1 to 30:2 C:V ratio.
 
NOTE:  The time scale is reflected in seconds for both graphs.

               5:1
   
  Upper tracing (ventilations) are shown delivering 600ml tidal volume with an Inspiratory to Expiratory (I:E) ratio of 1:2.  The lower tracing (compressions) are delivered at a rate of 100 compressions per minute (CPM) with a depth of 4 cm.

The 5:1 protocol delivers 70 compressions and 14 ventilations within one minute.

               30:2
   
  Upper tracing (ventilations) are shown delivering 600ml tidal volume with an Inspiratory to Expiratory (I:E) ratio of 1:1.5.  The lower tracing (compressions) are delivered at a rate of 100 compressions per minute (CPM) with a depth of 4 cm.

NOTE:  Upon exhalation of the second ventilation, the chest compressions resume.

The 30:2 protocol delivers 89 compressions and 4 ventilations within one minute.
