EKG Basics
This is the frequency of a Normal Sinus Rhythm
What is 60-100 bpm?
This is a sinus rhythm that is slightly irregular
What is sinus arrhythmia?
This bottle in the 3-bottle system is used to measure fluid drainage from the chest.
What is the collection bottle?
A mixed venous blood sample can be drawn from this part of the pulmonary artery catheter
What is the distal port?
This value correlates CO to body size
What is Cardiac Index?
This wave represents depolarization of the atria
What is the P wave?
This is the most fatal arrhythmia
What is ventricular fibrillation?
This is the proper insertion site for a chest tube to evacuate a pneumothorax?
What is the 2nd-3rd intercostal space, mid-clavicular line?
Cardiac Output can be measured with this part of the catheter
What is thermistor port?
This term describes the % of blood removed from the ventricles with each contraction
What is ejection fraction?
This term means the impulse originated from somewhere other than the SA node
What is ectopic focus?
This determines the amount of negative pressure applied to the chest.
What is the water height in the suction control bottle/chamber?
This part of the catheter can be used to measure right heart pressures
What is proximal port?
Positive pressure ventilation has this effect on venous return
What is decrease?
You would see this EKG change with acute myocardial infarction
What is ST segment elevation?
Continuous bubbling in the water seal chamber indicates this.
What is an air leak?
A venous blood sample can be drawn from this part of the catheter
What is proximal port?
This technique for cardiac output measurement is based on the temperature change of blood after injection of a cold solution in the RA.
What is the thermodilution technique?
These leads are known as bipolar leads.
What are the standard limb leads?
This bottle in the 3-bottle system ensures one-way movement of air.
What is the water-seal chamber?
If this balloon is left inflated for longer that 15 seconds, this can occur
What is ischemia?
This is the resistance the LV must overcome to eject the stroke volume
What is the SVR?
