Mistake

Generally speaking, we live our lives trying to avoid making a mistake. Perhaps it is because we were brought up to do everything as perfectly as possible. Perhaps it is because we fear the consequences. Perhaps it is because we refuse to accept that we are imperfect beings.

Regardless of the reason, we have a constant nagging voice in the back of our minds asking us: “Are you sure you want to do this? What if it’s all a big mistake?”.

This mentality affects our work, our financial decisions, our sense of adventure and even our relationships. Sometimes, we even go as far as not taking any action in fear of screwing it up. The fear of mistakes makes us take less risks and leaps of faith, hindering our ability to live a full life.

But to quote a great captain, Jean-Luc Picard:

“It is possible to commit no mistakes and still lose. That is not a weakness. That is life.”

Life is full of mistakes. No matter how hard we try to minimise risk, life will always find a way to trip you up. Because we are not a time-travelling supercomputer that can see and predict every variable, it is impossible to make no mistakes. Ergo, it is okay to make mistakes, because to err is to human.

In fact, mistakes are not always bad.

A “mistake” such as the singer’s voice cracking on a live performance may make it a more special performance, because it is a sign the singer poured all of their emotion and energy into the song, rather than playing it safe to avoid a mistake.

Columbus discovered the Caribbean because he mistakenly thought that he could reach Asia by sailing due west of Spain.

Everyone has a story of getting lost while travelling and stumbling onto an unforgettable experience that they could not have possibly planned for.

Sometimes, we will look back on our life and realise that what we thought was a mistake back then turned out to be a blessing in disguise, because each and every mistake we made led us to where we are now.

Lastly, we are all the products of billions of years of mistakes. Evolution is fundamentally based on the concept that genetic mistakes during cell division (mutations) allow for diversity of traits. Without mistakes, we wouldn’t even be here.

Of course, some mistakes carry irreversible, dire consequences, such as drinking and driving, or falling asleep while a nuclear reactor fails (Three Mile Island accident). But outside of these, most mistakes in life are something that you can learn something and move on from.

So don’t beat yourself up if you make a mistake.

It’s okay to make mistakes.

We are only human.

Scribbling

When we make a mistake while writing in pen, we usually scribble out the mistake. But whether you draw zigzags, spirals or scratch left and right, it is difficult to complete hide the mistake as the letters will show through the scribble. The brain has a fantastic skill of recognising letters, so it can read between the lines, so to speak.

To truly obscure your mistake or to redact confidential information, the best way to scribble it out is by writing on it. If you write over your mistake repeatedly with random letters of the alphabet, it will completely obscure whatever word lies beneath.

Flatline

When people think of the word “flatline”, they immediately visualise a medical crisis where a patient is lying unconscious, with doctors and nurses shouting out medical terminology while administering drugs, all to the suspenseful music and apathetic monotone and single horizontal line on the ECG machine. The doctor then shouts “Clear!” and proceeds to shock the patient with two paddles. This is repeated until some structures appear on the ECG, symbolising that the crisis has been resolved.

Of course this is a scene from a typical medical drama. Television shows, especially medical ones, are notorious for sacrificing medical accuracy for the sake of drama and tension. The “flatline” is the most cliché, repeated mistake made by almost every medical television show ever made.

The proper terminology for a flatline (a colloquial term), is asystole. This means that there is no systole, or contraction of the heart. An ECG (electrocardiogram) measures electrical signals in the heart, and in asystole there is insignificant amounts of electric activity, and the classic QRS complex is not seen. In this state, the heart is not pumping any blood and is electrically silent, meaning that the patient is clinically dead.

When asked how to treat this condition, the majority of people (even medical students) will shout “Shock!” or “Defibrillate!”. Defibrillation is the administering of an electrical shock to try “reboot” the heart, and correct the fibrillation – the chaotic electrical signal interfering with the normal, rhythmic electrical activity. Unfortunately, this is completely wrong yet so often depicted on television and films.
As asystole is a state of no electrical activity, there is no fibrillation to remove, nor is there anything to reset. Defibrillation in this state may even cause harm, causing tissue damage and lowering the chance of survival.

The correct treatment is injecting adrenaline (epinephrine in the U.S.A, atropine may be administered also) and CPR. Unfortunately, asystole is a condition that cannot be reversed, unless the heart somehow restores its own electrical activity. CPR merely keeps the patient’s perfusion going to preserve the organs for a longer time. Ergo, asystole signifies certain death, especially after 5 minutes where the heart will not respond to any drugs or electric shocks. In fact, asystole is one of the conditions required for the certification of a patient’s death.

Another related example of a (potentially fatal) misrepresentation of medicine in the media is the adrenaline injection. As mentioned before, this is the treatment for asystole. However, it is administered intravenously (into a vein) and never directly into the heart as in Pulp Fiction. This is more likely to kill the patient than save them, as the heart muscles could be damaged and delicate coronary arteries may become ruptured.

So why is it that the media continues to depict such blatant errors, that set a “common sense” that affect even medical professionals? This is most likely due to the audience wanting to see a dramatic scene, in a gripping life-or-death situation with drastic, powerful action. For example, the audience would much rather see the use of paddles or a giant needle being stabbed into the patient than seeing continuous CPR with no showy movements.

The next time you watch a medical television show, count how many times the doctors try to defibrillate a flatline.
