CHAPTER 49 – ELECTROCARDIOGRAPHY AND PULMONARY FUNCTION TESTING Crossword

Pulse ________________________ is a noninvasive test that measures the saturation of oxygen in a patient’s arterial blood
Readings less than 95% indicate__________________________ (low blood oxygen).
Electrodes are disposable pads attached to the patient’s skin during electrocardiography. Electrodes are placed on _________ areas of the body
A _______________________ (PEFR) is a is a measurement taken to determine the amount of air that can be quickly forced from the lungs
An artifact called a __________________________________ baseline is identified by a shift in the baseline from the center position for that lead
Cardiac ____________________________ or arrhythmia's are irregularities in the heart rhythm
_______________________________ (V-fib) is life-threatening and the ventricles of the heart appear to quiver because there is no cardiac output
The resting period of the heart occurs during ________________
The causes of a wandering baseline include mechanical and ______________________ interference.
In order to minimize electrical interference with the ECG, make sure all other ____________ equipment is turned off.
Forced vital capacity (FVC) is the greatest volume of air that a person can _____________ expel when performing a rapid, forced expiration.
__________________________ is the electrical impulse that starts a chain reaction resulting in a contraction of the heart
The cardiac ___________________ is a sequence of contraction and relaxation of the heart muscle.
