Answer 1

1.

EEG: It is a painless and safe technique to evaluate brain pathology such as brain tumours, seizures, etc. by recording the electrical activity taking place in the various segments of the brain. It is best for identifying the seizure disorder by identifying the type and area of origin within the brain. Here electrodes are placed on the brain through which electrical activities passes through it and helps to record the dimensions.

2.

EOG: electrooculogram is an electrophysiology cal test used to record the eye movement by measuring the electrical potential taking place between the cornea and retina of eye. In this technique the electrodes are placed on the skin near the right canthus and the left canthus of the eyes. Here recording of the electrical activity takes place according to the movement of positive charges.

3.

ECG: electrocardiogram is a graphical representation of the electrical impulses that are generated by the depolarization and repolarization of the myocardium of the heart.These impulses are conducted to the external surface of the body where they are detected by the electrodes that are placed on our body and it is measured by galvanometer. The S.A NODE (pacemaker of the heart )initiate the heartbeat by discharging an electrical impulse which spreads over the Atrium and ventricles, the atria contract and is followed by ventricular contraction (de polarization) as the wave of contraction passes of atria and ventricles relax (repolarization )this place takes place within each heartbeat 60 to 100 times per minute.

EMG: An electromyography is the recording of the electrical activity of skeletal muscle. Eectrical currents are produced by skeletal muscles called the muscle action potential. here small needle electrodes are introduced into the muscles to record the specific motor units because recording from the skin is not sufficient. Here the electrical potential of each muscles are amplified and transmitted to a cathode ray. oscilloscope is displayed on a screen the record may be made audible by playing on a loudspeaker and simultaneous analysis can be done. At rest no electrical activities are shown. It is used to to detect neuromuscular diseases.

Leg Wires:Leg wires are used in orthopedic surgeries. It is used to hold the bone fragments in place and for pin fixation in the skeleton. It is also used to provide an anchor for skeletal traction. It is available in different sizes.

Belts: Gait belts are used to maintain the gait of a person by holding each parts of the body in correct place. Gait belts are secured around the waist of the client inorder to assist them in sitting, standing, walking, etc.Medical transfer belts are also used for similar purpose to prevent injuries that may caused due to falling. Powerless parts of our body are fixed to wheelchair to prevent falling by using these balts.. It also maintains the posture.

Nasal Flow :Nasal flow cannulas are used for delivering oxygen to the client who needs respiratory assistance.

SpO2: SpO2 indicates the Oxygen saturation. It is used to measure the percentage of oxygen in our blood and thus understands how much effectively the person breaths. Normal SpO2 is 96% to 99%..

Snore:Snorting or grunting sound of the breath whike the person is asleep is called snoring. It may be caused due to extreme tiredness, consumption of alcohol, anatomical malformations of nose, etc.
