Monitoring Equipment Flashcards
Where does the waves of electrical activity start in the electro cardiogram
The waves of electrical activity starts in the sinoatrial node and travels to the internodal tracks through atrial contraction. Then it travels to the atrioventricular node where the purkinje fibers cause ventricular contraction
What does the P wave represent
Electrical depolarization of atrial myocardium prior to contraction
What does the QRS complex
Depolarization of ventricle myocardium prior to contraction
What does the T wave represent
Ventricular re polarization
What does the electrocardiograph do
Sensitive voltage metering instrument that amplifies hearts electrical impulses
What position does the animal need to be placed for an electro cardiogram
Right lateral recumbent sea on a non-conductive surface. Limbs need to be perpendicular and parallel to each other
What is a pair of electrodes called
A lead
What is the principal lead used to assess arrhythmias
Lead to placement
What is blood pressure
Pressure exerted by circulating blood on arterial walls
What is the systolic pressure
Highest pressure of the cardiac cycle
What is diastolic pressure
Lowest pressure of cardiac cycle
What is map
Mean arterial pressure
What is blood pressure an indicator of
Anesthetic depth
Cardiac function
Organ perfusion
What are two indirect blood pressure monitors
Doppler bp
Oscillometer bp
What is a Doppler bp monitor
Continuously monitor hr and heart rhythm
