Electronic patient monitoring Flashcards
Which designed to help you enhance patient care and clinal performance ?
Patient monitoring system also called (homecare telehealth)
Detects the difference between deoxygenated and oxygenated hemoglobin ?
Pulse Oximeter
(Normal values range from 95% to 100%)
( Below 95% is tissues are receiving
inadequate oxygen perfusion )
Provides continuous measurement of heart rate and includes ?
Arterial Catheter
includes:
A flush system , a pressure bag , a transducer , An Amplifier and Monitor
Device that measures the electrical activity of the heart , displays the form of waves ?
ECG (Electro cardio Graphy )
The first phase of contraction is ?
(The right and the left atrium )
which are stimulated by this electrical activity to contract and press blood into the lower chambers which are the ( right and left ventricles )
Contraction of these ventricles are ?
Second phase
Which receive an electrical impulse and then press blood up into the pulmonary arteries and into the aorta
Conduction of the heart ?
The electrical impulse from SA node
atria to AV node (Called conduction)
The electrical simulation of the muscle cells of the atria causes them to contract is ?
Atrial kick
Depolarization ? ( Systole)
The cell membrane permeability to Na
increases
Rapid influx of Na occurs
Potassium moves out of the cell
Repolarization: (Diastole)
Cells return to the resting state
Na leaves the cell & potassium returns
What is p wave , QRS , ST , T and U ?
Atrial depolarization
Ventricular depolarization ( 0.05 to 0.10 sec)
ventricular repolarization
ventricular diastole
repolarization of purkinjee fibers
Normal Sinus Rhythm ?
Ventricular & atrial rate : 60-100 in adult.
* Ventricular and atrial rhythm : Regular
* QRS shape and duration : regularly normal
* P wave : always in front of the QRS
* PR interval :- consistent interval between 0.12 and 0.20 sec
* P QRS ratio= 1:1
Ventricular& atrial rate is < 60 in adult is considered as ?
Sinus bradycardia
Ventricular rate > 100 but < 120 is considered as ?
Sinus tachycardia
ECG in radiology ?
Scan the heart when the heart is at rest between actual heart beats
Used to compare resting tracings with those obtained under the stress of physical exercise
ECG stress test
when there’s a lot of urea and kidney is not functioning well is called ?
Blood Urea Nitrogen (BUN)
Which means above 21 kidneys are (struggling to function) and above 50 (means renal failure)
What is a chemical by product of metabolism in the muscles ?
Creatinine which it is circulated through the blood and filtered by the kidneys
Above 1.5 – kidneys are not functioning adequately to filter out (normal 0.7 -1.5)
What another value that can be calculated from creatinine ?
Glomerular Filtration Rate (GFR)
What is GFR ( Glomerular Filtration Rate ) ?
estimates the rate at which the kidneys, as the glomerulus are filtering waste from the
blood.
Below 90 which kidneys are not functioning adequately to filter out
Normal : 90-120
What are non protein nitrogenous waste products ?
BUN and creatinine
What is byproduct of protein metabolism ?
Serum urea nitrogen ( BUN)
Blood Clotting Assessments ?
Is involved in the mechanism of forming blood clots
Platelet function test is known as ?
The Ivy bleeding time
