What the Health!

Did you know?
A number of American companies make their employees' day at work not only a happier, but also healthier place. They provide them with healthy meals, open office spaces, fitness classes or even child care centers. As an example, I would like to tell you about an American company in the heart of Silicon Valley: Google.



Google Headquarters, Mountain View, CA




"Let's face it," says Eric Schmidt, "programmers want to program, they don't want to do their laundry. So we make it easy for them to do both." Google's 44,777 employees seem to be damn lucky. Not only is it possible for them to get their laundry done, but also can they go to the hairdresser or even have a doctor's appointment on the 26-acre Google campus in Mountain View, California.


Food, Snacks and Haircuts?

After enjoying a free gourmet meal in the cafeteria, Google employees can spend the rest of their break playing Ping-Pong, pool or even volleyball. Some of them might even want to go to the on-site hairdresser - for free. Provided by a company called Onsite Haircuts, its mobile homes are travelling around cutting the hair of  "Silicon Valley's tech army."

Back to food and snacks: Throughout the day, the cafeteria offers healthy snacks like dried fruit, nuts or coconut water. Before they decided to offer nuts such as pistachios, some employees "had a serious M&M addiction", Google admits. By the way, all the snacks are available for free. Although, there is one thing Google charges its employees for: machine food. What is that? Machine food is food inside an automat. So you'd have to insert money in order to get food. Google set their prices quite high so as to avoid its employees to buy those rather unhealthy foods and gain weight.

By having about 20 cafeterias on the Google campus, employees can decide on where to go for lunch.

As mentioned above, there are various possibilities how Google employees can spend their breaks. What seemed most intriguing to me was that just recently, Google invented a lap pool. What is a lap pool? It's a very(!) small outdoor pool that is "equipped" with a strong current that allows one to swim and swim and swim - and go basically nowhere! Of course, Google arranged lifeguards in case someone drowns.

On the entire campus there are numerous lounges where Googlers can just hang out and talk. They're even allowed to bring their dogs to work: "The presence of dogs at Google has been a unique and to some, a treasured part of our workplace culture. Dogs can be a valued and important part of employees' lives, and their ability to keep a dog in their workplace may enhance the quality of their work life."

BTW: In order to make sure that employees make it to meetings in time, they are provided with scooters and, what is even more exceptional, the campus has a slide (yes, a slide!) which can be used instead of taking the stairs.





Health Care

In case Google employees don't have time for a doctor's appointment, they can go for a checkup to an on-site doctor instead. There are even chiropractors and massage therapists on the Google campus. What would you say about a nice massage during lunch break?
I'd like to stop at this point and recommend watching this video as it gives some more insight on how working at Google Headquarters is like. It's worth watching, I promise. Have fun!

How the Cardiovascular System Works

Hey guys.
Since I have learned a lot about how our heart works within my paramedic courses in 2012, I'd like to share some drawings I made during these courses. I labelled them in English in order to broaden my language skills. I really hope you can learn something from it. By the way, it might be a good idea to look at the drawings every once in a while while you're reading. Otherwise it might be a little confusing as there are LOADS of foreign words (of which some of them are explained below).


How the Heart Pumps Blood


(c) Sophie Schaffner

Our heart is a fist-sized muscle situated behind the rib cage and between the lungs. Since it is placed slightly to the left of the sternum (breastbone), the left part of the lungs is a little smaller than the right one. The heart contracts in order to pump oxygen- and nutrient-rich blood to the rest of your body.

The heart is divided into the right pumping system and the left pumping system. The right atrium (blue color) receives oxygen-poor blood from the superior vena cava and pumps it to the right ventricle (also in blue color). Following that, the right ventricle pumps the blood to the lungs through the pulmonary artery. In the lungs, the blood picks up oxygen and gets rid of carbon dioxide. The left atrium (red color), however, receives oxygen-rich blood from the pulmonary veins and pumps it to the left ventricle. Through the aorta, the left ventricle pumps the oxygen-rich blood to the rest of the body. The aorta (Aorta, Hauptschlagader) is the biggest artery and has millions of smaller arteries branching off. By passing through chest and abdomen, the aorta is responsible for "carrying" oxygen-rich blood to all your organs and cells.

Arteries are blood vessels that deliver oxygen-rich blood from the heart to the cells of your body. They are thick-walled and elastic and their smaller branches are called arterioles and capillaries.

Veins are thin-walled blood vessels delivering oxygen-poor blood to the lungs. Have you ever been wondering why blood in the veins of your feet flows upwards, although, locigally, gravity would keep it down below? Well, some veins have venous valves that set the direction where the blood moves. Thank God! Because otherwise all your blood would be stuck in your feet and ... yeah, you can imagine how your feet would look like.



The Cardiac Conduction System


(c) Sophie Schaffner

The cardiac conduction system generates and controls the heart rate. Have a look at the drawing first and search for the sinoatrial node (sinus node). This is where we start: The sinus node is the heart's natural pacemaker. The electrical impulses are generated here. This electrical signal moves from cell to cell down through the heart until it reaches the atrioventricular node (AV node). The AV node somehow slows the electrical current down. By doing so, the node ensures that the two atria (plural of atrium) can fully contract and pump out blood. After passing the AV node, the electrical current "travels" to the ventricels until it reaches the purkinje fibers (special cardiac muscles). These fibers kind of "tell" the cardiac muscles to contract.

Normally, a sinus node produces a heart rate of 60 to 80 per minute. In case the sinus node is not functioning anymore, the AV node takes over, but can only produce a heart rate of 40 to 60. By the way, the heart rate is the pulse you can feel at your wrist. The blood pressure, however, is something completely different and cannot be explained in just one sentence. If time allows, I will write another blog post and tell you what blood pressure actually is about.

Vocabulary

right atrium (rechter Vorhof) = the right upper chamber of the heart that receives blood from the vena cava
left atrium (linker Vorhof) = the left upper chamber of the heart that receives blood from the pulmonary veins
right ventricle (rechte Herzkammer) = the right lower chamber of the heart that receives blood from the right atrium and pumps the blood into the arteries
left ventricle (linke Herzkammer) = the left lower chamber of the heart that receives blood from the left atrium and pumps blood into the aorta
pulmonary artery (Lungenarterie) = an artery which carries blood from the heart to the lungs
venous valves (Venenklappen) = a structure that prevents blood from flowing backwards and therefore ensures a one-way flow
sinus node (Sinusknoten) = special part of the heart that controls the heart beat and heart rate
av node (AV-Knoten) = a node that receives impulses from the sinoatrial node
electric current (elektrischer Strom) = a flow of electricity

Being a Paramedic For One Day

Hey guys! :-)
Since we're currently covering the topics Health and Medicine, I would like to tell you how a typical 12-hour shift within the Ambulance-Services looks like. As you might have read in some of my preceding blog posts, I work as a voluntary paramedic at the Austrian Red Cross in Linz. I've made the experience that lots of people don't really know what a paramedic does all day long. Most of them assume a paramedic works in a hospital. That's completely wrong! So let yourself plunge into my world of  "being a paramedic (for one day)".

06:30 am - Getting ready for the shift

A typical shift starts at 7 am, which is why you need to check if the ambulance car you'll be driving with is OK. What does that mean? Within an ambulance car, you have a number of various equipment. All this equipment needs to be checked if it's working (e.g. the stretcher [folding bed used to transport the injured]), if it's still usable (e.g. the antiseptic) or how much oxygen you still have aboard (see the portable oxygen cylinders in the second picture). If everything's alright, you tell the dispatchers (the ones who take the calls and then send out the vehicles) by radio that you are available. Have a look at the pictures what we have in our ambulance cars (among lots of other stuff).



 

07:00 am - Ready to rumble!

Now that the dispatcher knows we're on standby, we might receive a call soon. We don't know what's going to happen next or which kind of patient we're going to get. Maybe it's just an elder woman who is living alone, toppled and can't stand up on her own. Or we assume the worst and we could be sent to a car accident. Anything can happen!

7:44 am - Our fist mission

Beep, beep the radio goes. It's time to save the world.

Yeah, About that phrase... Many people become a paramedic because they believe they are going to save the entire world. Not quite. I don't know about my colleagues, but I have never saved the whole world before. And I suppose I won't do so any time soon. Being a paramedic isn't always about saving someone's life. Instead, we provide first aid in order to relieve the suffering of individuals. Frequently, we pick up our patients at home to bring them to the hospital. For instance: A patient has their leg in a plaster cast and can't go to the hospital on their own. In order to make the doctor's appointment at the hospital happen, we fetch the patient and transport them there. So let's not say we save the world, but rather try to ease someone's pain by giving first aid or giving someone a ride.

Have a look at the picture on the right hand side. This is what our terminal looks like. For those of you who speak German, you'll find that no trouble to understand. There are a few abbreviations, though, which even German speakers might not be familiar with.

So let's have a closer look:
EO stands for Einsatzort, which means the place where something happened (e.g. an accident) and we therefore need to go to in order to help our patients; the Irish Red Cross calls it the incident location.
Dia stands for Diagnose, which means diagnosis. In this particular case we have a patient who suffers from Tachykardie (tachycardia). The prefix tachy- says that something is accelerated whilst cardio/cardia is always linked to the heart. If we have problems with our heart, for example, we would see a cardiologist.
Pat stands for Patient (patient). Our dispatchers always suggest to which hospital our patient should be brought. In this case it says nach AKH. That means we'll bring our patient to the general hospital.
KEO stands for Koordinaten Einsatzort and tells us the exact coordinates of our incident location.
In the very last line we come to know that a GP had a look at the patient already and finds it necessary to bring him to the hospital. (HÄND war vor Ort).

How will we treat our patient?
Our patient suffers from tachycardia, which means that their heart beats really really fast right now. First of all, we will tell our patient to breathe calmly. One of us will feel their wrist to check the pulse. A normal heart beat is about 80 (+/- 20) per minute. Our patient has a pulse of 130(!). We also take their blood pressure, which turns out to be at a normal rate (120/80). The most important thing now is to quickly bring our patient to the hospital. While driving to our destination, the patient should sit up straight as that's easier to breathe. After the patient is brought to the emergency room, we will drive back to our station and hopefully have some coffee there.


10:13 am - The next mission's certain to come.

After having a longer break at the station, the radio beeps again. This time, the beep goes way faster and louder. There are two different radio sounds: the slower one tells us that it's not a matter of life and death, but the faster one does. So we'll finish our coffee quickly and get started.

On our terminal we get to know the following: In the first line the dispatchers tell us that we have to turn our flashing blue light on ("Blaulicht"). The diagnosis says bewusstlos, which means unconscious. In the penultimate line we get to know that a doctor on emergency call is going to be there as well ("NEF 1 ebenfalls").

Since our patient is unconscious, we need to place them in recovery position. I am not going to explain here what the recovery position is about. If you like to read a more detailed explanation how to place someone in recorvery position, have a look at one of my previous blog posts called "How to place someone in Recovery Position". What's more is that we will administer oxygen to our patient in order to make their breathing easier. We'll also cover our patient with a blanket made of aluminum. We don't want them to feel cold, do we?
Generally speaking, since a doctor was sent to the incident location too, he's the one to call the shots. We'll place the patient on the stretcher, of course still being in recovery position, and set off. After dropping the patient off at the emergency room, we drive back to our station and have a break.



12:30 pm - Enjoy your meal!

I'm starving! When volunteers work the day shift, they get coupons to get free lunch at one of the hospitals in Linz. Most of the time, we receive coupons from the "Landes- Frauen- und Kinderklinik" - a hospital that emphasizes on toddlers, children and expectant mothers.

This is how a typical lunch in a hospital looks like. What do you think about it? Does it look delicious to you? Would you call it "gourgeous" as Jamie Oliver always does?




04:47 pm - Last but not least.

What we have here is something that we experience in almost every (night) shift: alcohol abuse. No, we're not the ones , but our patient. Sadly, like in every bigger city, there are people living in a poorhouse or even on the street. Actually, we don't transport these kind of patients to the hospital because they have a problem with alcohol. Instead, we bring them there because when they are drunk, they do silly things like sleeping outside or trip and fall. We neither want them to feel cold, nor do we want them to bleed or feel pain. 

It can be a bit nerve-wracking to pick up a drunk guy who talks a lot of nonsense or might even be aggressive. In case a patient is aggressive, I call the cops so that they escort us to the hospital. It's a lot more secure for us paramedics to have a police officer on our side.

What will we do with this patient?

Well, the most important thing is to, again, bring the patient to the hospital. Before that we'll feel their wrist to check the pulse and take a blood sample so as to measure their blood sugar. If the person had been sleeping outside, we make sure to cover them with a blanket. Otherwise the patient might suffer from hypothermia. What does that mean? Hypo always refers to something that is below a normal frequence or value. In contrast, hyper means that something is above a certain value. "Thermia" refers to temperature, which means that hypothermia is when your body temperature gets low so that it even might endanger yourself.


06:45 pm - Exhausted, but satisfied.

Our shift is drawing to an end. For twelve hours we've been available for people in need. We didn't exactly save the world. Instead, we tried to ease people's pain and bring them to the hospital. That's actually a lot. Even when we're quite exhausted right now, we can be proud of ourselves!

If you have any questions on that, please don't hesitate to text me! :-)
