ABG Quality control/analyzers
takes blood gas analysis from the specialized laboratory to the patient’s bedside
Point-of-care testing
In ABG interpretation, the term “acute” is also referred to as what?
Uncompensated
Electrical impulses originating from site other than SA node
Ectopic
What is the normal duration of QRS complex?
0.6-0.11 seconds
Every other beat is a PVC
Bigeminy
A sample obtained from a warmed capillary site is often refer as:
Arterialized blood
What is the normal venous blood value of PCO2?
46 mmHg
Atrioventricular (AV) node
Medication used to treat problematic sinus bradycardia
Atropine
Considered as a very dangerous type of PVC
This is performed to ensure that the analyzer output is both accurate and linear across the range of measured values
Calibration
What needs to compensate in order to fix metabolic issue?
PaCO2
Change in speed of conduction through AV node
Dromotropic effect
This type of arrhythmia is usually common in kids and elderly
Sinus Arrhythmia
Amplitude < 3 mm, less electrical activity, and less chance for survival
Fine Vfib
Blood gas monitoring that provides continuous, noninvasive estimates of arterial PO2 and PCO2 through a surface skin sensor
Transcutaneous
What is the appropriate action when PaO2 value is >101 mmHg in patient that is on room air?
Re-analyze blood sample
Corresponds with onset of QRS to peak of T wave
Absolute refractory period
Narrow Complex Tachycardia is also known as:
Paroxysmal Supraventricular Tachycardia (PSVT)
Conduction from SA to AV is completely blocked
3rd Degree block
What is the safe upper limit of sensor temperature to avoid thermal injury?
42°C
What is the best way to ensure accuracy when analyzing ABG?
Sample free of preanalytic errors
Difference in concentration of ions across a cell membrane at any given point
Action potential
Most common type of pre-excitation syndrome
Looks like idioventricular, except faster
accelerated idioventricular
