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.
Infants often have a normally irregular respiratory rhythm, so count their respiratory rate for 1 full minute, preferably while the infant is calm or asleep (for the most accurate rate). A normal respiratory rate for this age group is between 30 and 60 breaths per minute. normal respiratory rate for an adolescent is between 16 and 20 breaths per minute. Again, be aware of the signs of respiratory distress (tachypnea, retractions, and nasal flaring) and if you observe these, initiate treatment immediately.
