Which Of The Following Is Not A Bls Intervention

Let's explore the core principles and procedures of Basic Life Support (BLS) to clarify what constitutes a BLS intervention. This will involve dissecting the critical components of BLS, differentiating between various interventions, and ultimately identifying what actions or procedures fall outside the scope of BLS.

Understanding Basic Life Support (BLS)

Basic Life Support (BLS) refers to a level of medical care used for victims of life-threatening illnesses or injuries until they can be given full medical care at a hospital. It typically involves non-invasive procedures that can be performed by trained individuals, including healthcare providers, first responders, and laypersons. The primary goal of BLS is to maintain the airway, breathing, and circulation (the ABCs) without the use of advanced equipment.

Core Components of BLS

To understand what is not a BLS intervention, it's crucial to first establish what is included. BLS primarily consists of the following:

1. Recognition of Cardiac Arrest and Activation of Emergency Response:

   • Rapidly identifying that someone is in cardiac arrest is the first critical step. This involves checking for responsiveness and normal breathing.
   • Activating the emergency response system (calling 911 or the local emergency number) to ensure that advanced medical care is on its way.

2. Cardiopulmonary Resuscitation (CPR):

   • Chest Compressions: Delivering chest compressions at the correct rate (100-120 compressions per minute) and depth (at least 2 inches or 5 cm for adults) to circulate blood to the vital organs.
   • Rescue Breaths: Providing breaths to deliver oxygen to the victim's lungs, typically using a ratio of 30 compressions to 2 breaths (30:2) for adults.

3. Automated External Defibrillator (AED) Use:

   • Applying and using an AED as soon as one is available. The AED analyzes the heart rhythm and, if necessary, delivers an electrical shock to restore a normal rhythm.

4. Relief of Foreign-Body Airway Obstruction (FBAO):

   • Performing abdominal thrusts (Heimlich maneuver) on adults and children or back blows and chest thrusts on infants to dislodge an object blocking the airway.

Detailed Explanation of BLS Interventions

1. Recognition and Activation

The initial moments are critical in BLS. Recognizing the signs of cardiac arrest—unresponsiveness and absent or abnormal breathing (gasping)—requires immediate action. Once recognized, the rescuer must activate the emergency response system. This ensures that advanced medical personnel are en route. The rescuer should provide specific information to the dispatcher, including the location of the emergency, the condition of the victim, and any known medical history.

2. Cardiopulmonary Resuscitation (CPR)

CPR is the cornerstone of BLS. It involves two primary components: chest compressions and rescue breaths.

• Chest Compressions: Effective chest compressions are vital for circulating blood to the brain and heart. The rescuer should:
  • Place the heel of one hand in the center of the victim's chest, between the nipples.
  • Place the other hand on top of the first, interlacing the fingers.
  • Position themselves directly over the victim’s chest.
  • Compress the chest to a depth of at least 2 inches (5 cm) but no more than 2.4 inches (6 cm) for adults.
  • Maintain a rate of 100-120 compressions per minute.
  • Allow for full chest recoil after each compression.
• Rescue Breaths: Rescue breaths provide oxygen to the victim's lungs. The rescuer should:
  • Ensure the airway is open using a head-tilt-chin-lift maneuver (unless a spinal injury is suspected, in which case a jaw-thrust maneuver should be used).
  • Pinch the victim's nose closed.
  • Create a tight seal over the victim's mouth with their mouth.
  • Give two breaths, each lasting about one second, and watch for chest rise.
  • Allow the chest to fall before giving the next breath.
  • Continue cycles of 30 compressions and 2 breaths.

3. Automated External Defibrillator (AED)

The AED is a portable device that can analyze the heart rhythm and deliver an electrical shock if needed. Using an AED involves the following steps:

• Turn on the AED and follow the voice prompts.
• Attach the AED pads to the victim's bare chest. One pad goes on the upper right side of the chest, and the other goes on the lower left side.
• Ensure that no one is touching the victim while the AED analyzes the heart rhythm.
• If the AED advises a shock, ensure that everyone is clear of the victim and press the shock button.
• After delivering the shock, immediately resume CPR, starting with chest compressions.
• Continue following the AED prompts until advanced medical help arrives.

4. Relief of Foreign-Body Airway Obstruction (FBAO)

When a person is choking, they may be unable to breathe, speak, or cough effectively. The rescuer should:

• Ask the person, "Are you choking?" If the person nods and cannot speak, proceed with the Heimlich maneuver.
• For Adults and Children:
  • Stand behind the person and wrap your arms around their waist.
  • Make a fist with one hand and place the thumb side against the person's abdomen, slightly above the navel but below the rib cage.
  • Grasp your fist with your other hand and give quick, upward thrusts into the abdomen.
  • Continue thrusts until the object is dislodged or the person becomes unresponsive.
• For Infants:
  • Hold the infant face down over your forearm, supporting the head and jaw.
  • Give five back blows between the infant's shoulder blades using the heel of your hand.
  • If the object is not dislodged, turn the infant face up, supporting the head.
  • Place two fingers on the center of the infant's chest, just below the nipple line, and give five quick chest thrusts.
  • Repeat back blows and chest thrusts until the object is dislodged or the infant becomes unresponsive.

What Is Not a BLS Intervention?

Now that we have a clear understanding of what BLS entails, it is easier to identify what falls outside its scope. Interventions that require advanced medical training, equipment, or are invasive are generally not considered part of BLS. Here are several examples of what is not a BLS intervention:

1. Advanced Airway Management:

   • Endotracheal intubation, which involves inserting a tube into the trachea to secure the airway, is an advanced procedure.
   • Laryngeal mask airway (LMA) insertion is also an advanced technique.
   • BLS focuses on basic airway maneuvers such as head-tilt-chin-lift or jaw-thrust.

2. Medication Administration:

   • Administering drugs such as epinephrine, atropine, or antiarrhythmics is beyond the scope of BLS.
   • BLS providers may assist with patient's own medications (e.g., helping someone use their epinephrine auto-injector for anaphylaxis) but do not administer drugs themselves in a resuscitation context.

3. Intravenous (IV) Access and Fluid Administration:

   • Starting an IV line to administer fluids or medications is an advanced procedure.
   • BLS focuses on maintaining circulation through chest compressions, not through fluid replacement.

4. Cardiac Monitoring and Rhythm Interpretation:

   • While AEDs can analyze heart rhythms and deliver shocks, interpreting complex ECG rhythms beyond AED prompts requires advanced training.
   • Continuous cardiac monitoring to assess the patient’s condition is not a BLS intervention.

5. Needle Decompression for Tension Pneumothorax:

   • This procedure involves inserting a needle into the chest cavity to relieve pressure caused by a collapsed lung.
   • It requires specific training and is not within the scope of BLS.

6. Surgical Procedures:

   • Any surgical intervention, such as a cricothyrotomy (creating an emergency airway through an incision in the neck), is an advanced procedure.

7. Pain Management:

   • Administering pain medication is not a BLS intervention.

8. Advanced Diagnostic Procedures:

   • Performing or interpreting diagnostic tests like blood gas analysis, X-rays, or CT scans is beyond the scope of BLS.

9. Manual Defibrillation:

   • While AEDs are part of BLS, manual defibrillation, which requires interpreting complex ECG rhythms and manually setting the energy level for the shock, is an advanced procedure.

Scenarios to Illustrate BLS vs. Non-BLS Interventions

To further clarify the differences, consider the following scenarios:

• Scenario 1: A person collapses in a shopping mall. A bystander checks for responsiveness and breathing, finds none, and calls 911. The bystander then starts chest compressions and uses an AED to deliver a shock. This is a BLS intervention.

• Scenario 2: Paramedics arrive on the scene and insert an endotracheal tube to secure the patient's airway, start an IV line to administer medications, and use a manual defibrillator to deliver a precisely measured shock based on the patient's ECG. These are advanced life support (ALS) interventions, not BLS.

• Scenario 3: A child is choking on a piece of candy. A trained BLS provider performs abdominal thrusts until the candy is dislodged. This is a BLS intervention.

• Scenario 4: A patient in the intensive care unit (ICU) develops a tension pneumothorax. A physician performs a needle decompression to relieve the pressure. This is an advanced procedure, not BLS.

Why Is It Important to Know the Difference?

Understanding the distinction between BLS and advanced interventions is crucial for several reasons:

• Appropriate Response: Knowing what you are trained and equipped to do ensures that you provide the most appropriate care in an emergency.
• Patient Safety: Attempting interventions beyond your skill level can be harmful to the patient. Sticking to BLS protocols ensures that you provide effective care without causing additional harm.
• Effective Coordination: When advanced medical help arrives, knowing what interventions have already been performed allows for a smoother transition of care and better coordination.
• Legal and Ethical Considerations: Performing procedures without proper training and authorization can have legal and ethical implications.

The Importance of Training and Certification

BLS training and certification are essential for anyone who may need to respond to a medical emergency. These courses provide hands-on training in the core components of BLS, ensuring that individuals are competent and confident in their ability to provide life-saving care. Certification typically lasts for two years, after which recertification is required to stay up-to-date with the latest guidelines and best practices.

Current Guidelines and Recommendations

BLS guidelines are regularly updated by organizations such as the American Heart Association (AHA) and the International Liaison Committee on Resuscitation (ILCOR). These guidelines are based on the latest scientific evidence and are designed to improve the effectiveness of resuscitation efforts. Staying current with these guidelines is crucial for all BLS providers.

Conclusion

Basic Life Support is a critical set of skills that can save lives in emergency situations. It focuses on the fundamental components of maintaining airway, breathing, and circulation through non-invasive procedures. While BLS is a powerful tool, it is essential to recognize its limitations and understand what falls outside its scope. Advanced airway management, medication administration, IV access, and surgical procedures are examples of interventions that require advanced medical training and are not part of BLS. By understanding these distinctions, BLS providers can deliver appropriate and effective care while waiting for advanced medical help to arrive.
