The term ‘bypass’ is an anglicism that could literally be translated as ‘lateral step’. In the new edition of the Spanish Language Dictionary, the Castilianized form ‘baipás’ is admitted.

Bypass in medicine

This word is used especially in medicine. In this context, a bypass to all types of surgical procedures that create an alternative diversion or conduit that functions as a bridge between two parties, in order to solve a certain health problem.

Cardiac bypass

A coronary bypass is performed when there is an obstruction or narrowing in one of the coronary arteries, which reduces blood flow.

This type of bypass consists of grafting a prosthesis or a segment of a blood vessel in the coronary artery, in order to evade and replace the obstructed area and redirect blood flow.

In this way, the coronary bypass allows to restore circulation and prevent complications such as myocardial infarction.

Electric bypass

An electric bypass is a deviation from an electrical circuit that allows direct communication between two points.

As for electronic equipment, the online UPS has a variant called bypass , which consists of a parallel step that derives the electric current directly from the input to the output of the UPS.

Computer bypass

In this case, the bypass refers to a form of evasion of a computer security system.

Bypass in urban planning and public works

In urban planning, it is called bypass or overpass to create a passage in the communication routes, which opens to cross from one place to another through a bridge, without obstructing the flow of another avenue.

Audio bypass

It refers to an interruption in sound effects during the audio mixing process, in order to access the original sound.
