What is a laryngoscope?

Laryngoscope is an illuminating medical tool used to the healthcare provider to enable the visualization of the pharynx and larynx. The pharynx is directly behind the nose and mouth, and the larynx is better known as the voice box. The laryngoscope is specially designed to fit into the patient's airways to allow the procedure known as orotracheal intubation in which the tube is inserted by mouth into the trachea or wind pipe to deliver oxygen and medicines and allow deep suction. The handle contains the batteries needed for lighting and the blade, which is inserted into the airways, has a light light at the end of the bulb, from which bright light is lit during use. These blades are not sharp and do not cut the skin. Laryngoscopic blades come in different sizes, with 0 the smallest and 4 are the largest. The size of the patient to be intubated deturcates the size of the blade used by the healthcare provider.

Handle and čThe EPEL typical laryngoscope is two separate pieces that must be collected before every use, but this can be achieved in seconds, allowing doctors and rescuers to use this tool in respiratory emergencies that require orotracheal intubation. Laryngoscope is not a big tool; The handle is approximately the size of the door handle and the blade is slightly shorter than the handle. There are two types of laryngoscope blades: curved and straight. Both are inserted deep into the patient's respiratory tract.

The direct blade is used to raise the structure in the shape of the leaves called epiglottis, which is used to prevent food and foreign substances to enter the wind, and this type of blades is generally preferred when a pediatric patient must be intubated. The curved blade of an adult patient's wslep must be intubated. It is not an epiglottis that is lifted by a curved blade that is inserted into another structure called vallecula. Regardless of the type of blade used is the same goal, which is allowedthe thread of the visualization of the vocal cords through which the endotracheal tube can be transferred to the trachea. The importance of monitoring the vocal cords is that it is essential for the doctor or rescuer to intubate orotracheal intubation to guarantee the tube into the trachea and not to the esophagus, the tube leading to the stomach.
