Code Blue: Just Like on T.V.
“I’m not a doctor.  I just play one on T.V.â€Â Well actually, in real-life emergency services, things are nothing like on T.V. We operate in uncontrolled environments dealing with weather like rain dripping on us, wind blowing us and our patients, dark ditches, cluttered environments, and in a moving vehicle while going around corners. Not to mention limited equipment, basically what we can carry with us into homes and what we can fit into an ambulance as well as limited personnel. And on top of that we have to make up for these things by carrying lots of equipment, and thinking of everything and by being knowledgeable in many different areas including scene management, safety, medicine, pharmacology, cardiology,  customer service, psychology, and equipment maintenance just to name a few. “How do you do all that?†you might wonder. The answer is easy. We love our jobs and we are dedicated to serving the community. We don’t always get a lot of thanks, but we know we serve a purpose and have the potential to make a life or death difference in someone’s life. In this blogisode I’m going to discuss how we use our diverse knowledge, equipment and lots of team work when someone calls 911 when experiencing a cardiac arrest.
 Usually this event begins when someone notices that they are experiencing the most common symptom of a heart attack: chest pain or pressure. This happens when the arteries that supply blood to the heart muscle become significantly occluded or blocked by plaque formed by cholesterol or fat in the blood. This can happen slowly over time or fairly quickly. This is why it is so important to get checked out early in this type of event. If left untreated, a blockage denies parts of the heart muscle of blood which supplies oxygen to the cells and removes the waste created by cellular respiration. Consequently the heart muscle can become damaged and eventually parts of the muscle can die. This can lead to cardiac arrest or the heart muscle stopping completely. When the heart muscle stops pumping, blood is not supplied to other parts of the body including the brain causing whole body cell damage and eventual death. During this process the brain shuts down different parts of the body and stops regular processes including breathing.
The purpose of EMS in this situation is to stop this process and reverse the effects restoring the bodily function of putting oxygen into the body, pumping the heart to circulate the oxygen through the body to the organs, brain and other cells and to get the individual to a level one cardiac cath lab where the cath lab team does heart surgery to break up or remove the blockage in the heart.
 When a person calls 911 the dispatch center pages our department to respond to the patient. When we arrive at a patient, we do many different things all at once which can be overwhelming to the patient and their family but we have many jobs to do and we try to keep the patient and their family in consideration and explain to them what we are doing and why. We ask questions about medical history, medications, what is going on. We assess the patient’s level of responsiveness, airway, breathing and circulation and overall status. We begin treatments based on the findings of our assessments.Â
 The worst case scenario is when the person is not breathing and their heart is not pumping. We then immediately begin manually pumping the heart also known as chest compressions or CPR. Functionally, this circulates blood to the heart and around the body. We begin breathing for the patient with supplemental oxygen. We place I.V. lines to push medications directly into the circulation while manually circulating blood by continuing to do chest compressions to circulate the medications to the heart. There are different medications that work in different ways depending on what is wrong with the heart which we determine by our assessments and by using our EKG monitors which show 12 views or pictures of the electrical activity in the heart which we are trained to interpret. We also use the heart monitor machines to give electrical therapy which includes “shocking†the patient. This is done when the heart is spasming and not functionally pumping. A fast electrical current stops the heart and gives it a chance to reset itself and begin pumping normally. We can also use electrical current in conjunction with medications to slow down or speed up the heart if it is beating too fast or too slowly. In addition, we also often place a breathing tube directly into the patient’s trachea to secure the airway and keep secretions or vomit from entering the lungs. We can also use ventilators to automatically breathe for patients if necessary. All these things are started on scene and often continued on scene for a period of time until movement of the patient is feasible.
 Obviously this is a lot of things to accomplish with three to five EMS personnel in a very short period of time. To do this we train for 9 hours per month and have really functional teamwork. Often we also utilize the fire department and the police department staff to assist us in moving the patient and equipment as well as to give us extra sets of hands during these types of events. Our ambulance service is blessed to have a great working relationship with our police and fire department personnel who are knowledgeable and willing to assist however they are needed.
 There are new technologies and equipments coming out very rapidly to assist in the challenges EMS faces in keeping people alive and more importantly, alive with a prognosis of minimal damage to the body, brain and heart. River Falls Ambulance is committed to giving our community members the best available patient care. Therefore our main project for this year is to upgrade our cardiology capabilities. You may have seen the article in the River Falls Journal on our project or our video spot on RFC-TV’s River Falls In Focus with Mayor Don Richards, if not you can check them out on-line.Â
 One of the new pieces of equipment that we are raising funding for is called a LUCAS device. The LUCAS is a piece of equipment that fits around the patient’s chest and does chest compressions in place of a person doing chest compressions. This frees up a staff member to do or assist in other tasks during this demanding process. Also, being mechanical it delivers more consistent chest compressions than a human can factoring in the demands of the task and fatigue. The compressions delivered by the LUCAS are better because the compressing mechanism is a lot like a toilet plunger and it works between chest compressions to expand the chest allowing the heart to refill more completely with blood to be pumped out to the body. This results in more efficient circulation than regular compressions done by a person.
 Another part of the project is called Post Cardiac Arrest Induced Hypothermia or Cardiac Cooling. The Idea behind this is: when the heart, brain and other organs are starved of blood the cells are damaged and begin to die. Cooling the patient to a point of hypothermia slows down the body’s metabolism and in turn slows down the process of damage and death to cells. So, by cooing the patient, we can slow the damage process to the cells and organs such as the heart and brain. We do this after we have used medications and electrical therapy to restart the heart but before the person wakes up and if the person doesn’t wake up.   Meanwhile, we can be getting the person to a level one cardiac cath lab like the one at United Hospital in St. Paul, MN which we can generally get to in about 20-25 minutes, where they can remove the blockage in the heart allowing the body to go back to functioning normally. We have worked in partnership with United Hospital to develop the policies we will use to implement this process.
  To cool our patient to the point of slowing metabolism requires medical grade refrigerators that are portable and kept in the ambulances. We will use saline cooled to a precise temperature, given intravenously to cool the body along with placing the patient in a cooling bag with actual ice cubes. To keep the saline at the proper temperature requires medical grade refrigerators that we are also raising funds for.Â
 Our staff is dedicated to giving our community members the best care and service available. They offer their time for very little compensation and most of them have other full-time jobs and families as well as other obligations. They give on-call time as well as give much time toward initial and maintenance training. We are blessed to have such a dedicated staff and such a supportive community to make this project a reality. This project will give us more tools in our bag of tricks to use toward not only saving lives but giving a better chance of survival with an intact quality of life.
