How to Assess Respiratory Emergencies

Respiratory emergencies demand immediate action. Here’s how to quickly assess and manage them:

• Check Breathing: Look for labored or irregular breathing, and listen for unusual sounds.
• Measure Vital Signs: Count breaths (normal: 12–20/min for adults) and check oxygen saturation (SpO2 > 95%).
• Inspect Skin: Look for bluish discoloration (cyanosis) around lips or mouth.
• Evaluate Chest Movement: Ensure both sides of the chest expand equally; uneven movement may indicate problems.
• Use Medical Tools: Perform peak flow tests, blood gas analysis, or imaging (e.g., X-rays) for further insights.

Key Emergencies to Identify:

• Asthma: Rapid breathing, accessory muscle use, low peak flow readings.
• COPD: Pursed-lip breathing, SpO2 < 88%, elevated CO2 levels.
• Pneumonia or Pulmonary Embolism: Crackles vs. clear lungs, distinct vital sign patterns.
• Collapsed Lung: No breath sounds on one side, tracheal shift, and low oxygen levels.

Act swiftly – monitor for signs of respiratory failure like confusion, oxygen saturation below 90%, or extreme breathing rates. Use tools like capnography and imaging to guide treatment.

Respiratory Assessment – Emergency Nursing

First Steps in Emergency Assessment

In respiratory emergencies, it’s crucial to perform a quick and structured evaluation to determine the necessary interventions.

Check Breathing and Patient Condition

Start by visually assessing the patient for any obvious signs of breathing difficulties. Look for signs like labored breathing, irregular chest movements, or unusual sounds.

Then, assess the severity of the situation by observing how the patient is breathing.

Measure Breathing Rate and Oxygen Levels

Count the patient’s breaths over a full minute to get an accurate respiratory rate. Use a pulse oximeter on their finger or earlobe to measure oxygen saturation. For adults, a normal breathing rate is typically between 12–20 breaths per minute, and oxygen levels should be above 95%. Any values outside these ranges could indicate a problem that needs attention.

Check the skin next for signs of oxygen deprivation.

Look for Blue Skin and Other Warning Signs

Inspect the patient’s skin for discoloration, particularly a bluish tint around the lips, tongue, or mouth. This can be a sign of poor oxygenation and should be addressed immediately.

Hands-on Assessment Steps

Check Chest Movement

Look closely at the patient’s chest to see if it expands evenly on both sides. Uneven movement can signal a respiratory problem. After observing, use touch to gather more information about how the chest is functioning.

For those wanting to sharpen their observation techniques, Respiratory Cram provides specialized training modules on identifying irregular chest movements.

Medical Testing Equipment

Modern tools for respiratory assessment provide essential data during emergencies, helping healthcare professionals make quick and informed decisions.

Peak Flow Tests

Peak flow meters measure how effectively air moves out of the lungs, making them useful for assessing airway obstruction in conditions like asthma and COPD. Typical peak flow readings range from 400 to 600 liters per minute but can vary depending on factors like age, height, and gender.

Steps to use a peak flow meter:

• Ensure the patient is seated or standing upright.
• Set the meter to zero.
• Ask the patient to take a deep breath.
• Instruct them to blow out as hard and fast as possible into the device.
• Record the highest reading from three attempts.

Blood Gas Testing

Arterial blood gas (ABG) analysis provides key insights into oxygen levels, ventilation, and acid-base balance. The test measures several parameters that are crucial for diagnosing respiratory issues:

These values help identify the type and severity of respiratory failure, guiding immediate treatments. After ABG analysis, imaging and CO2 monitoring provide further clarity about respiratory conditions.

X-rays and CO2 Monitoring

Chest X-rays play a vital role in respiratory emergency assessments, quickly identifying issues like pneumonia, pulmonary edema, or pneumothorax. Portable X-ray units allow for bedside imaging, enabling rapid diagnosis and treatment.

End-tidal CO2 (ETCO2) monitoring, performed through capnography, gives continuous updates on:

• Ventilation efficiency
• Proper airway placement
• Effectiveness of CPR
• Early signs of respiratory decline

Normal ETCO2 levels fall between 35 and 45 mmHg. Deviations from this range can signal serious respiratory problems. Capnography provides real-time feedback, allowing for immediate intervention and ensuring treatments are on track.

Major Breathing Emergencies

Learn to identify the key signs of respiratory emergencies to take quick and effective action.

Asthma and COPD Attacks

For asthma, watch for these signs:

• Rapid, labored breathing using accessory muscles
• Trouble speaking full sentences
• Peak flow readings less than 50% of the person’s normal level

For COPD, keep an eye out for:

• Pursed-lip breathing
• Leaning forward in a tripod position
• Increased effort to breathe
• Oxygen saturation (SpO2) below 88%
• Elevated end-tidal CO2 (ETCO2) levels over 45 mmHg

Quickly check how the patient responds to bronchodilators and monitor oxygen levels. Be cautious – too much oxygen can make COPD symptoms worse. Also, rule out pneumonia or embolic events by evaluating vital signs and listening to lung sounds.

Pneumonia and Blood Clots

When breathing problems are caused by infections or blockages in blood vessels, specific assessments can help pinpoint the issue.

Use these vital sign differences to distinguish severe pneumonia from a pulmonary embolism:

Breath sounds can also provide clues:

• Pneumonia often causes crackles and reduced breath sounds.
• Pulmonary embolism may present with clear lungs despite severe symptoms.

Collapsed Lung Emergency

Key signs of a collapsed lung (pneumothorax) include:

• No breath sounds on the affected side, with a hollow sound (hyperresonance) when percussed
• Trachea shifting away from the affected side in severe cases

Vital sign changes to watch for:

• Low blood pressure
• Heart rate above 120 beats/minute
• Respiratory rate over 30 breaths/minute
• Oxygen saturation dropping despite oxygen therapy

Physical signs:

• Swollen neck veins
• Limited chest movement on the affected side
• Air trapped under the skin (subcutaneous emphysema) may require immediate needle decompression.

Across all emergencies, stay alert for respiratory failure signs:

• Confusion or altered mental state
• Inability to maintain oxygen saturation above 90% even with oxygen
• Breathing rates over 35 or below 8 breaths/minute
• Intense use of accessory muscles for breathing

Summary

Effectively assessing respiratory emergencies requires a structured approach. Start by evaluating the patient’s breathing and level of consciousness. Follow this with a detailed physical examination, including observing chest movement, palpation, percussion, and listening to lung sounds.

When additional clarity is needed, tools like pulmonary function tests, blood gas analysis, and imaging studies can help determine the severity of the condition. These techniques enable clinicians to identify underlying problems and act swiftly.

Ongoing practice and education are key to maintaining the skills necessary for managing respiratory emergencies efficiently.
