The first step in any resuscitation is to make sure the rescuers you! Therefore, if your victim is in the middle of the highway or in a burning building, the first step is to move the victim to safety. Assuming you and the victim are in a safe location, the next step is to assess whether the patient is responsiv. Adult BLS is slightly different if there is one provider solo or more than one provider team present. The difference between solo provider BLS and team BLS is that responsibilities are shared when more than one person is present.

For healthcare providers, the difference between a witnessed cardiac arrest and a victim who is found down is the order of the initial steps. Cardiac arrest is the sudden sensation cessation of blood flow to the tissues in brain the results from a heart that is not pumping effectively.

Four rhythms may occur during cardiac arrest: ventricular fibrillation, pulseless ventricular tachycardia, pulseless electrical activity, and asystole. While ACLS provides algorithms for each of these cardiac arrest rhythms, in the real world a patient may move between these rhythms during a single instance of cardiac arrest. Therefore, the provider must be able to accurately assess and adapt to changing circumstances.

After every 2 minutes of CPR, check for a pulse and check the cardiac rhythm. If the rhythm has switched from shockable or to shockable, then switch algorithms. This energy may come in the form of an automated external defibrillator AED defibrillator paddles, or defibrillator pads. VFib and VTach are treated with unsynchronized cardioversion, since there is no way for the defibrillator to decipher the disordered waveform. In fact, it is important not to provide synchronized shock for these rhythms.

Ventricular fibrillation is recognized by a disordered waveform, appearing as rapid peaks and valleys as shown in this ECG rhythm strip:.

Ventricular tachycardia may provide waveform similar to any other tachycardia; however, the biggest difference in cardiac arrest is that the patient will not have a pulse and, consequently, will be unconscious and unresponsive.

Two examples of ventricular tachycardia are shown in this ECG rhythm strips. The first is narrow complex tachycardia and the second is wide complex tachycardia:.

Pulseless electrical activity or PEA is a cardiac rhythm that does not create a palpable pulse is even though it should. A PEA rhythm can be almost any rhythm except ventricular fibrillation incl. It represents a lack of electrical activity in the heart. It is critically important not to confuse true asystole with disconnected leads or an inappropriate gain setting on an in-hospital defibrillator.

Asystole may also masquerade as a very fine ventricular fibrillation. If the ECG device is optimized and is functioning properly, a flatline rhythm is diagnosed as asystole. Note that asystole is also the rhythm one would expect from a person who has died.

Consider halting ACLS efforts in people who have had prolonged asystole. It is inappropriate to provide a shock to pulseless electrical activity or asystole. Cardiac function can only be recovered in PEA or asystole through the administration of medications.

While cardiac arrest is more common in adults than respiratory arrest, there are times when patients will have a pulse but are not breathing or not breathing effectively e. A person who has a pulse but is not breathing effectively is in respiratory arrest.

When you encounter a patient in need, you will not know he or she is in respiratory arrest, so perform a BLS survey:. In ACLS, the term airway is used to refer both to the pathway between the lungs and the outside world and victim in the devices that help keep that airway open. As if the victim may have experienced head or neck trauma, airway management should include a jaw thrust, which leaves the head and neck unmoved, but which opens up the airway.

A nasopharyngeal airway, which extends from the nose to the pharynx, can be used in both conscious and unconscious patients. An oropharyngeal airway can only be used in unconscious patients because it may stimulate the gag reflex. Advanced airways such as endotracheal tubes ET tubes and laryngeal mask airways LMAs usually require specialized training, but are useful in-hospital resuscitations especially LMAs. Many different disease processes and traumatic events can cause cardiac arrest, but in an emergency, it is important to be able to rapidly consider and eliminate or treat the most typical causes of cardiac arrest.

To facilitate remembering the main, reversible causes of cardiac arrest, they can be organized as the Hs and the Ts. Atrial fibrillation is the most common arrhythmia. It is diagnosed by electrocardiogram, specifically the RR intervals follow no repetitive pattern.

Some leads may show P waves while most leads do not. Atrial contraction rates may exceed bpm. The ventricular rate often range is between to bpm. Atrial flutter is a cardiac arrhythmia that generates rapid, regular atrial depolarizations at a rate of about bpm. This often translates to a regular ventricular rate of bpm, but may be far less if there is a or conduction. By electrocardiogram, or atrial flutter is recognized by a sawtooth pattern sometimes called F waves. Narrow QRS complex tachycardias include several different tachyarrhythmias.

One of the more common narrow complex tachycardias is supraventricular tachycardia, shown below. Wide complex tachycardias are difficult to distinguish from ventricular tachycardia. Ventricular tachycardia leading to cardiac arrest should be treated using the ventricular tachycardia algorithm. A wide complex tachycardia in a conscious person should be treated using the tachycardia algorithm. There are four main types of atrioventricular block: first degree, second degree type I, second degree type II, and third degree heart block.

Second degree heart block Mobitz type I is also known as the Wenckebach phenomenon. Atrioventricular blocks may be acute or chronic. Chronic heart block may be treated with pacemaker devices.

From the perspective of ACLS assessment and intervention, heart block is important because it can cause hemodynamic instability and can evolve into cardiac arrest. In ACLS, heart block is often treated as a bradyarrhythmia.

The PR interval is a consistent size, but longer or larger than it should be in first degree heart block. Complete dissociation between P waves and the QRS complex.

No atrial impulses reach the ventricle. The results of the ECG will be the primary guidance for how the patient with possible cardiac chest pain is managed.

The ECG diagnosis of acute coronary syndrome can be complex. In people who are candidates for fibrinolytics, the goal is to ad mister the agent within 3 hours of the onset of symptoms. ACLS in the hospital will be performed by several providers. These individuals must provide coordinated, organized care. Providers must organize themselves rapidly and efficiently. Resuscitation demands mutual respect, knowledge sharing, and constructive criticism, after the code.

When performing a resuscitation, the Team Leader and Team Members should assort themselves around the patient so they can be maximally effective and have sufficient room to perform their role. Advanced Cardiac Life Support, or ACLS, is a system of algorithms and best practice recommendations intended to provide the best outcome for patients in cardiopulmonary crisis. ACLS protocols are based on basic and clinical research, patient case studies, clinical studies, and reflect the consensus opinion of experts in the field.

Once you become certified in ACLS, the certification is valid for two years. However, we encourage you to regularly login back in to your account to check for updates on resuscitation science advances. As we learn more about resuscitation science and medicine, physicians and researchers realize what works best and what works fastest in a critical, life-saving situation. Therefore, it is necessary to periodically update life-support techniques and algorithms.

If you have previously certified in advanced cardiovascular life support, then you will probably be most interested in what has changed since the latest update in The table below also includes changes proposed since the last AHA manual was published. These changes will likely appear in future editions of the provider manual. The Chain of Survival is a sequence of steps or links that, when followed to its completion, increases the likelihood that a victim of a life-threatening event will survive.

The adult and pediatricchains of survival are slightly different. The person who is providing BLS is only responsible for the early links, that is, making sure the person is cared for by emergency personnel. The emphasis on early care is to reinforce that time is a critical factor in life supportcare.

The standards include the concept of out of hospital care versus in-hospital care. In fact, it is assumed that all people who are pursuing ACLS will be competent in the techniques of BLS—so much so that it is considered a prerequisite to ACLS The first step in any resuscitation is to make sure the rescuers you! Assuming you and the victim are in a safe location, the next step is to assess whether the patient is responsiv If patient is not responsive, move to BLS survey If patient is responsive, move to ACLS survey.

Shake and Shout! Check for effective breathing for 5 to 10 seconds. In the community, call and send for an AED 3. Circulation Check the carotid pulse for no more than 10 seconds. If no pulse, begin high quality CPR. Defibrillation If there is a shockable rhythm, pulseless ventricular tachycardia or ventricular fibrillation, provide a shock. If you are alone and witness a victim suddenly collapse: Assume cardiac arrest with a shockable rhythm.

If you are alone and find an unresponsive adult: Tailor response to the prospective cause of injury. Check to see if the victim is responsive. Shake and shout! Is the victim breathing effectively? Does the victim have a pulse in the carotid artery? If you witnessed the victim suddenly collapse, assume cardiac arrest with a shockable rhythm. Follow directions on the AED.
