ABG quality control/analyzers
When the respiratory and metabolic blood gasses are both acidotic/alkalotic
What is combined (mixed) acidosis/alkalosis?
Decreased oxygen in the blood
What is hypoxemia?
This is located approximately at the level of the second intercostal space
What is the base of the heart?
There should be one ___ for each QRS
What is a P wave?
This term is used when all PVC's look alike and come from one irritable spot
What is a unifocal PVC?
A metabolic pH problem
What type of problem is balanced by the lungs?
This is known as an availability problem caused by decreased o2 carrying capacity in the blood
What is anemic hypoxia?
The protective sac that surrounds the heart
What is the pericardium?
What is sinus tachycardia?
This is the most common type of ventricular arrhythmia
What is a premature ventricular complex?
The primary cause is hypoventilation
What is respiratory acidosis?
pH measuring, pH reference (Sanz), PCO2 (Severinghaus), PO2 (Clark)
What are the 4 types of electrodes?
This wave is rarely seen and represents the repolarization of Purkinje fibers and papillary muscles
What is a U wave?
This happens when P waves take on a "saw-tooth" pattern
What us atrial flutter?
This happens when there are other wires/leads near your electrodes during a 12-lead EKG
What is AC interference?
This site for sticking is typically reserved for extreme cases and pediatrics
What is the dorsalis pedis?
24-30 mEq/L
What is the venous normal blood gas value for HCO3?
These muscle fibers connect the AV node with the two bundle branches
What is the Bundle of His?
This happens when an SA node fires normally, but the tissue around it doesn't carry impulse
What is a sinus exit block?
This rhythm occurs when the cardiac output is zero
What is ventricular fibrillation?
When drawing ABG's, a 3cc syringe is loaded up with this much anti-blood clotting solution
What is a 1:1000 heparin solution?
A known cause of this type of hypoxia is diffusion or neuromuscular impairment
What is hypoxic hypoxia?
These are a small bundle of nerve fibers, often compared to the arterioles in lung airways
What is a fascicle?
At a rate of 40-60bpm, this happens when an SA node doesn't fire and all beats come from the AV junction
What is a junctional escape?
this type of PVC is often referred to as the precursor to Vtach and Vfib
What is the R on T phenomenon?
