(46 cards)
An ECG that uses 4 leads attached to the patient’s skin; these include the limb leads
4-lead ECG
An ECG that uses 12 leads attached to the patient’s skin; these include the limb leads and chest leads.
12-lead ECG
A sealed hub on an administration set designed for sterile access to the intravenous fluid
access port
An abnormal rhythm of the heart
arrhythmia
The complete absence of any electrical cardiac activity, appearing as a straight or almost straight line on an ECG strip
asystole
The act of viewing the electrical activity of the heart through the use of an ECG machine or cardiac monitor
cardiac monitoring
A flexible, hollow structure that drains or delivers fluids
catheter
The cutting of the catheter by the needle during improper rethreading of the catheter with the needle; the severed piece can then enter the circulatory system
catheter shear
The leads that are used only with a 12-lead ECG and must be placed exactly; includes leads V1-V6
chest leads
A multilumen airway device that consists of a single tube with two lumens, two balloons, and two ventilation ports; an alternative airway device if endotracheal intubation is not possible or has failed
Combitube
The area of the administration set where fluid accumulates so that the tubing remains filled with fluid
drip chamber
Another name for administration sets
drip sets
Electrocardiogram; an electronic tracing of the heart’s electrical activity through leads, which originate in the electrocardiograph machine and contain electrodes that attach to the patient’s chest and/or limbs
ECG
A network of special cells in the heart through which an electrical current flows, causing contractions of the heart that produce pumping of blood
electrical conduction system
Insertion of an endotracheal tube directly through the larynx between the vocal cords and into the trachea to maintain and protect an airway
endotracheal intubation
plastic, disposable indicators that signal by color change when an endotracheal tube is in the proper place
end-tidal carbon dioxide detectors
IV access established in the external jugular vein of the neck
external jugular IV
removal of a tube after it has been placed
extubation
An advanced airway adjunct that provides a channel directly into a patient’s stomach, allowing for removal of gas, blood, and toxins and for instilling medications and nutrition
gastric tube
A measure of the interior diameter of the catheter. It is inversely proportional to the true diameter of the catheter
gauge
The escape of fluid into the surrounding tissue when the IV catheter is not in the vein
infiltration
Rigid, boring catheters placed into a bone to provide intravenous fluids
intraosseous (IO) needles
Intravenous solutions that do not cause a fluid shift into or out of the cell; examples include normal saline and lactated Ringer’s solutions
isotonic crystalloids
A disposal supraglottic airway used as an alternative to tracheal or mask ventilation
