Electromyogram (EMG). An electromyogram (EMG) is a neurological test, usually performed by a neurologist, which evaluates the responses of muscles and the nerves that supply them.It is performed by inserting small needles into various muscles that act as stimulating and recording electrodes.he EMG provides the physician with information about the functioning of both the muscle and the nerves that supply that muscle. This can be used to help diagnose various diseases that affect these structures.
Respiratory rate: The number of breaths per minute or, more formally, the number of movements indicative of inspiration and expiration per unit time.In practice, the respiratory rate is usually determined by counting the number of times the chest rises or falls per minute.The aim of measuring respiratory rate is to determine whether the respirations are. normal, abnormally fast (tachypnea), abnormally slow (bradypnea), or nonexistent (apnea).espiratory rate: The number of breaths per minute or, more formally, the number of movements indicative of inspiration and expiration per unit time.
MEASURING RESPIRATORY RATE The human body continuously exchanges oxygen and carbon dioxide through the act of respiration.Normal respiratory rates are dependent upon age. Assessment of Respiratory Rate Counting the number of respirations per minute assesses resp-iratory rate. The nurse observes the full respiratory cycle (one inspiration and one expiration) for rate and pattern of breathing. The clientâs respiratory rate is assessed by counting the number of breaths for 30 seconds and then multiplying by 2. If the nurse detects irregularities or difficulty breathing, the respirations are counted for one full minute. Factors That Influence Respiratory Rate The respiratory rate in some clients may increase if they become aware that their breaths are being counted. For this reason, the nurse should maintain the posture of counting the radial pulse while counting breaths per minute. Other factors that may in-crease respiratory rate include exercise, stress, increased temper-ature, and increased altitude.
