Hospital secrets

What is a "Code Gray" and what you should know if you hear it at the E.R.

A trip to the emergency room can be stressful enough without hearing doctors and nurses speak a language that sounds like a secret code. One minute, someone is asking for medication "STAT," the next there’s a "Code Gray," and another patient is suddenly "NPO." What do those words really mean? Some are official medical terms, others are insider slang, but they all help hospital staff communicate quickly when every second counts. Here are 10 of those codes explained.

The E.R. can be hectic and unpredictable. Most patients are frightened or uncomfortable, but now and then someone becomes aggressive because of pain, confusion, mental illness, or the effects of alcohol or other substances. That’s when you can hear "Code Gray" announced over the speakers.

The code is used to summon security officers to help manage a violent or combative situation. While color codes vary from one hospital to another, Code Gray commonly signals that staff needs extra assistance to protect patients, visitors, and healthcare workers. Even if you know it now, most people in the waiting room never know what happened, and that’s exactly the point.

You have a scheduled surgery, you’re in your bed waiting to be taken to the surgery room, and you ask for a cup of coffee to make the wait lighter. The nurse will probably tell you you’re an NPO. You may think it’s serious, but it’s simply a procedure.

"NPO" is an abbreviation that comes from the Latin phrase Nil Per Os, which means "nothing by mouth." It tells patients they cannot eat, drink, or sometimes even take medication until doctors say it’s safe. The rule is most common before surgery or certain medical tests, when food or liquids could increase the risk of complications or alter the results. It may be frustrating, but it’s an important part of keeping patients safe.

You’ve probably been through the experience of visiting an emergency room, either to get checked or to visit a loved one. In that part of the hospital where everyone is rushing to save lives, you’ve probably heard a doctor asking for the R.C.P. cart or medication "STAT!" It sounds urgent, and that's because it is.

The expression comes from the Latin statim, which means "immediately" or "without delay." Hospitals have used Latin medical terms for centuries, but STAT is one of the few that remains part of everyday conversation. When a doctor says it, the request jumps to the top of the priority list. It doesn’t always refer to a life-or-death situation, but it does mean the medical team needs something done as quickly as possible.

Newborns are always a reason to celebrate at the hospital. Parents usually rest happily next to their child as they receive congratulations from close relatives. However, the hospital is always prepared to handle extremely rare emergencies under "code pink."

If you hear a "Code Pink," it usually means a baby or young child is suspected of being abducted from the hospital. Within seconds, security officers respond, exits may be monitored or blocked, and staff begins following carefully rehearsed procedures. Although different hospitals sometimes use different color codes, Code Pink has become widely recognized across North America as one of the most serious alerts a hospital can issue.

If you’ve ever spent a few days in the hospital, you’ve probably noticed that some patients are walking up and down the halls, while others need help just getting out of bed. When a nurse refers to someone as a "walkie-talkie," it’s actually good news.

This informal expression refers to patients who can walk on their own, use the bathroom without assistance, and handle most basic tasks independently. It’s not an official medical term, of course, but it’s commonly used among healthcare workers because it quickly tells the next shift that the patient requires less hands-on care than many others.

As nurses change shifts, you’ll often hear them give a quick report about each patient. One person may only need medication, while another is described as a "total."

The term is short for a patient who requires total care. They may need help eating, bathing, getting dressed, turning in bed, or moving from one place to another. Although the expression sounds impersonal, it’s simply a practical way for caregivers to communicate how much assistance someone needs.

Most people hear "frequent flyer" and think of an airline reward program. And that’s correct, but in an emergency room, the phrase has a very different meaning.

A frequent flyer is an informal nickname for patients who repeatedly return to the hospital, often due to chronic illness, recurring medical conditions, or other ongoing health issues. Behind the light-hearted nickname is often a difficult reality. Many of these patients are simply dealing with medical problems that require regular emergency care, and the expression is just a way to make the experience a bit lighter among the familiar faces of doctors and nurses.

Not all codes are for patients. The next time you’re in a hospital, look closely at what the nurse is pushing from room to room. It may look like a small rolling desk with a computer on top. Staff often call it a "WOW," short for "workstation on wheels."

As hospitals switched from paper charts to electronic medical records, these mobile computers became essential. Nurses use them to review test results, scan medications, update patient charts, and check doctors’ orders without leaving the bedside. The name sounds funny, but the technology helps caregivers spend more time with patients instead of walking back and forth to a nursing station.

After getting a shot or having blood drawn, most patients never think about where the used needle ends up. It certainly doesn't go into an ordinary trash can.

Hospitals place needles, scalpels, and other sharp medical instruments into special containers designed to prevent accidental injuries. These sturdy, puncture-resistant boxes are sealed when full and safely disposed of in accordance with strict health regulations. This not only protects nurses, but it also protects cleaning crews, waste handlers, and even the public from dangerous needle sticks. It’s one of the most important safety measures in every hospital, even though most patients never notice it.

If you’ve ever watched a medical drama, you've probably seen a patient become so agitated that several staff members rush into the room. In situations like that, a doctor or nurse may ask for a "B-52." But the name has nothing to do with numbers themselves; it actually comes from a medicine.

B-52 is hospital slang for a fast-acting injection used to calm down patients who are severely combative or at risk of harming themselves or others. The nickname comes from a commonly used combination of medications that usually include diphenhydramine, haloperidol, and lorazepam. It’s strictly reserved for when other methods of calming the patient haven’t worked.

It’s not always possible to attribute the origin of a precise word to a particular person. However, it is believed that William Shakespeare contributed more than 1,700 terms and expressions to the English language, many of which we still use today. The way Shakespeare invented, reused, and modified words is a living testament to his creativity and innovation. In this article, we have handpicked 10 words and phrases that you probably didn’t know were coined by the genius English poet and playwright. And the next time you use them, remember that you are following in the footsteps of a true linguistic legend!

Loneliness is a sentiment we can all relate to. Who hasn't felt lonely at some point? Feeling sad about being apart from others is universal. But the interesting thing is that this word, which we use frequently in the English language, was first introduced in a play by William Shakespeare.

Written between 1605 and 1608, Coriolanus is a tragedy set in the earliest days of the Roman Republic. In the first scene of Act 4, General Coriolanus, speaks to his mother Volumnia, who tries to convince him not to attack Rome, and says: "Believe 't not lightly-though I go alone, / Like to a lonely dragon that his fen."

Thanks to William Shakespeare, we have a polite and decent idiom to express we are happy and relieved to see someone leave without resorting to insults and rudeness. What a treat! Although riddance is practically an obsolete term in modern English, the expression "good riddance" has stood the test of time.

Shakespeare first used it in The Merchant of Venice when Portia says to the Prince of Morocco: "A gentle riddance! Draw the curtains, go, / Let all of his complexion choose me so." In this case, the phrase didn’t have the ironic connotation that it would acquire later and that we still use today. That aspect would come with Patroclus' comment in Troilus and Cressida replying to Thersites' insolence when he finally leaves: "A good riddance."

The word gossip has a long and intricate history. It is believed to derive from the combination of the Old English word sibb, meaning "relative", and the word god. The term godsibb was used to refer to a person spiritually related to another, that is, a godparent. A few centuries later the word evolved into its current form, gossip, and its meaning was extended to anyone who liked to talk about other people's private lives.

However, the verb form we use today, to gossip, is entirely due to Romeo and Juliet's creator. It was Shakespeare who first used the term as a verb in three of his comedies: The Comedy of Errors, All's Well That Ends Well, and A Midsummer Night's Dream. Well, no wonder—a good writer is, at heart, a great gossip.

You may be familiar with this line from Aldous Huxley's famous book published in 1932. But the truth is that Huxley borrowed the title for his dystopian novel from Shakespeare. The English playwright used the phrase ironically for the first time in his play The Tempest. The naïve Miranda, confined since childhood to an island with no contact with men other than her father, says upon seeing some sailors: "O wonder! / How many goodly creatures are there here! / How beauteous mankind is! O brave new world, / That has such people in 't."

Today, we use the phrase in the same cynical and ironic way Shakespeare conceived it more than 400 years ago. When something is about to change in history or society but we are not quite confident about the outcome, "brave new world" comes to mind, and it is impossible to resist using it. At least now we know its origin!

Romeo and Juliet is a symbol of romantic love and is a story that has been adapted thousands of times in literature, film, television, and music. The words used by Shakespeare to describe the landscapes of Verona and the characters’ physical attributes are unforgettable and have remained in the memory of readers for centuries. Even when we are not aware that many of those words were invented or put on paper for the first time under the pen of the genius playwright!

"Thou wilt quarrel with a man for cracking / nuts, having no other reason but because thou / hast hazel eyes. What eye but such an eye would spy / out such a quarrel?" says Mercutio. This is the earliest record of the word hazel in reference to a color, in this case, to describe Romeo’s eyes. Fun fact: in the Elizabethan period, it was considered a reddish-brown color, rather than the greenish-brown we think of today.

Do you consider yourself a nocturnal person? Someone who prefers to be active at night rather than during the day? If so, you are probably a night owl! But did you know that Shakespeare was the first to use the expression figuratively to describe people keen on nightlife?

In classical literature, the owl was an animal with negative connotations and was typically associated with bad omens. In Shakespeare's plays, they appear frequently, usually to announce that something bad is about to happen. However, in the narrative poem "The Rape of Lucrece," the night owl refers directly to a person: "The dove sleeps fast that this night-owl will catch: / Thus treason works ere traitors be espied." We’ve all felt a bit like a night owl at one time or another, but fortunately, nowadays the expression doesn't carry that negative connotation.

Shakespeare's fascination with Italy is well known. Renaissance literature was profoundly influenced by the ideas, styles, and themes that emerged in Italy during this period. In the case of Shakespeare, the Italian influence is evident in the settings, themes, characters, and language of his plays.

In the same way that the author recovered terms and expressions from Old English, he also adapted words from other languages that were later incorporated into the popular lexicon. This is the case of the word bandit, which derives from the Italian bandito and literally means "one who is banished," referring to an outlaw who lives by stealing and other misdeeds. The first written record of bandit can be found in the play Timon of Athens.

Jealousy is a common human emotion that can eat away at a person. Literature has dealt with this topic in many ways, and Shakespeare is one of the authors who has done it most brilliantly. In fact, he coined a term to describe people who suffer from such deep jealousy that they can cause harm to others and themselves: the "Green-Eyed Monster."

In The Merchant of Venice, The Bard had already linked the color green with envy when Portia says: "And shudd'ring fear, and green-eyed jealousy!". Then, in Othello, the arch-villain Iago warns the protagonist, who is blind with jealousy over his wife Desdemona's alleged affair with Cassio: "O, beware, my lord, of jealousy! / It is the green-eyed monster which doth mock / The meat it feeds on."

William Shakespeare not only invented words, turned nouns into verbs, and added prefixes, but he's also credited with having coined a few female names that are still very popular today. Miranda, Olivia, Cordelia, and Imogen are just some of them.

This is also the case with Jessica, who first appears in The Merchant of Venice as the rebellious daughter of Shylock. As was his habit, it is believed that the author anglicized a biblical name from the Old Testament —possibly 𝘠𝘪𝘴𝘬á𝘩. Some years later, in the late 18th century, people in Britain began naming their daughters Jessica after the Shakespearean character. Fast forward to this day, the name has crossed the pond, and chances are you have a friend or cousin named Jessica.

Shakespeare loved to play with language: he invented words, redefined others, and gave new life to thousands of forgotten terms and expressions. As far as we know he especially liked to add the prefix un-. He created or gave new meanings to more than 300 words that begin with it, such as unaware, unreal, uncomfortable, and undress. One of the most curious words in this group is unfriend.

Although the word already existed, it had not been used as a verb before the 17th century. The English author includes it in several of his works to refer to someone who has been left alone, without friends. For example, it appears in the romantic comedy Twelfth Night and King Lear: "Will you, with those infirmities she owes, / Unfriended, new-adopted to our hate." In the 21st century, the term had a revival with the advent of Facebook. Shakespeare could never have imagined the rise of social media, but he would surely be happy that his contributions to language are still relevant today.
