Introduction to Respiratory Emergencies
Respiratory emergencies require immediate attention. Recognizing the signs and symptoms is crucial. Common causes include:
- Asthma: Bronchospasm leading to narrowed airways. Symptoms: wheezing, shortness of breath, coughing, chest tightness.
- COPD (Chronic Obstructive Pulmonary Disease): Progressive lung disease. Symptoms: chronic cough, shortness of breath, excess mucus production, wheezing.
- Choking (Foreign Body Airway Obstruction): Blockage of the airway. Symptoms: inability to speak, cough, or breathe; grasping the throat; universal choking sign (hand to throat).
- Hyperventilation: Rapid, deep breathing leading to decreased carbon dioxide. Symptoms: rapid breathing, dizziness, tingling in extremities, anxiety. Important Note: While hyperventilation can cause distress, it is not always a true respiratory emergency that needs direct intervention, but the distress must be addressed.
Airway Opening Techniques
A patent airway is the foundation of effective respiratory care. Use these techniques:
- Head-Tilt/Chin-Lift: Used when no spinal injury is suspected. Place one hand on the patient's forehead and tilt the head back. Place the fingers of the other hand under the bony part of the chin and lift, bringing the chin forward. (See diagram/video for proper technique).
- Jaw-Thrust Maneuver: Used when spinal injury is suspected. Place your fingers behind the angles of the jaw and lift the jaw forward, keeping the head and neck in a neutral position. (See diagram/video for proper technique).
Important Considerations: Always assess for responsiveness first. Ensure the patient is lying supine. Look, listen, and feel for breathing after opening the airway. If the patient is not breathing or is breathing inadequately, begin rescue breathing.
Airway Adjuncts (If Permitted and Within Scope of Practice)
Airway adjuncts help maintain an open airway.
- Oropharyngeal Airway (OPA): A curved plastic tube inserted into the mouth, over the tongue, to the back of the throat. Measure from the corner of the mouth to the earlobe to determine the correct size. Insert the OPA with the tip pointing towards the roof of the mouth; rotate 180 degrees once the tip reaches the back of the mouth.
- Nasopharyngeal Airway (NPA): A soft, flexible tube inserted into the nostril. Measure from the nostril to the earlobe. Lubricate the NPA before insertion. Insert gently along the floor of the nasal passage. (Review local protocols and scope of practice. NPA's are contraindicated in some situations like head trauma.)
Important: Ensure proper sizing and placement. Use lubrication. Be aware of contraindications (e.g., suspected skull fracture, severe facial trauma). Monitor for complications (e.g., gagging, vomiting).
Rescue Breathing and Supplemental Oxygen (If Permitted and Within Scope)
If the patient is not breathing or is breathing inadequately:
- Rescue Breathing: Use a pocket mask or bag-valve mask (BVM) to provide breaths. Ensure a tight seal. Deliver breaths over 1 second, observing for chest rise. Give breaths at a rate of 1 breath every 5-6 seconds (adults).
- Supplemental Oxygen: If permitted and within your scope, administer oxygen via nasal cannula or face mask. Titrate to achieve an oxygen saturation of at least 94%. Follow local protocols and guidelines. Oxygen administration must be within scope, training, and medical direction.

Deep Dive: Beyond the Basics of Respiratory Emergencies
This section explores more nuanced aspects of respiratory emergencies, building upon the foundational knowledge of airway management and breathing assistance. We'll delve into recognizing subtle signs, understanding the underlying pathophysiology, and considering the psychosocial impact on patients.
Atypical Presentations & Subtle Clues: While the textbook signs of respiratory distress (wheezing, dyspnea, cyanosis) are crucial, recognize that not every patient presents with such obvious symptoms. Consider age, pre-existing conditions, and medications. For instance, elderly patients or those with chronic conditions might exhibit more subtle signs, such as increased confusion, restlessness, or subtle changes in skin color. Pay close attention to changes in the patient's level of consciousness, as this is often an early indicator of hypoxia.
Pathophysiology Focus: Briefly consider the underlying physiological mechanisms behind common respiratory emergencies. Understanding the "why" can help you anticipate complications and tailor your response. For instance:
- Asthma: Bronchospasm, inflammation, and mucus production lead to narrowed airways, hindering airflow.
- COPD: Chronic inflammation and structural damage within the lungs (emphysema and chronic bronchitis) result in impaired gas exchange.
- Pulmonary Embolism: A clot blocks blood flow to the lungs, reducing oxygen delivery and potentially causing right-sided heart strain.
- Anaphylaxis: A systemic allergic reaction triggers bronchoconstriction and swelling of the upper airway.
Psychosocial Impact: Respiratory distress is inherently frightening. Patients may experience anxiety, panic, and a feeling of impending doom. Approach the patient with empathy, maintain a calm demeanor, and provide clear and concise explanations of what you are doing. Remember that your nonverbal communication (body language, tone of voice) significantly impacts their experience.
Bonus Exercises
Sharpen your skills with these supplementary exercises.
Exercise 1: Scenario-Based Assessment
You are drawing blood from a 68-year-old patient with a history of COPD. During the procedure, the patient becomes increasingly anxious and complains of chest tightness and shortness of breath. Their breathing is rapid and shallow. You observe slight cyanosis around the lips. Their SpO2 reading is 88%. What are your immediate actions? What questions would you ask to gather more information? What equipment would you prepare?
Exercise 2: Airway Obstruction Simulation
Using a mannequin or partner, practice abdominal thrusts (Heimlich maneuver) and back blows on an adult or infant (depending on your training and scope). Vary the scenario: a conscious patient, an unconscious patient, and a patient in a wheelchair. Practice assessing for effective chest compressions if required.
Real-World Connections
This knowledge extends far beyond the phlebotomy chair. Being adept at recognizing and responding to respiratory emergencies can be invaluable in a variety of situations.
- Family & Friends: Your skills can help you assist loved ones in emergencies.
- Community Events: Volunteer at community events and provide first aid.
- Everyday Awareness: Become more observant of your surroundings and able to recognize signs of distress in public.

Rescue Breathing Simulation
Using a mannequin, practice rescue breathing using a pocket mask or BVM. Simulate different scenarios of respiratory distress (e.g., asthma, choking) and implement the correct response, including assisting with a mask and/or oxygen (if applicable).
Scenario Analysis: Respiratory Distress
Read a case study of a patient experiencing respiratory distress. Identify the signs and symptoms, determine the likely cause, and outline the appropriate steps for assessment and intervention. If permitted, include applying the relevant airway management techniques.
Peer Review and Role-Play
Pair up and practice the skills learned throughout the lesson. Take turns as a patient experiencing respiratory distress, and as a phlebotomist providing aid. Discuss any challenges and review techniques.
Practical Application
