Is there a reason why epinephrine dosing intervals in cardiac arrest patients is set to q4min instead of q3-5 minutes as per AHA guidelines? 
By having them set at q4min, it puts the provider in stressful situation trying to sequence the doses at a specific time rather than a range as suggested by AHA. 

The dosing interval of 4 minutes for epinephrine administration in cardiac arrest under the Medical Cardiac Arrest Medical Directive was not intended to cause undue stress. This dosing interval was chosen as a single number, directly within the recommendation of the AHA. SWORBHP Medical Council understands that in this high acuity, dynamic call that epinephrine dosing administration may not be exactly 4 min. The result of managing a complicated resource intensive call may be that epinephrine dosing is 3 or 5 min intervals and this is acceptable given the entire context of the call and is still within AHA recommendations for optimal management.
