Proper assessment of breathing is crucial in Pediatric Advanced Life Support (PALS). This article details the key components of a thorough breathing assessment in pediatric patients, helping healthcare providers quickly identify and manage respiratory compromise. Accurate and timely assessment can significantly impact patient outcomes.

Assessing Breathing: The PALS Approach

The PALS approach to breathing assessment is systematic and efficient. It focuses on identifying signs of respiratory distress or failure promptly. The assessment isn't just about counting breaths; it's about observing the *entire* picture.

1. Initial Visual Assessment: Look for the Obvious

Begin by visually inspecting the child. This initial observation can reveal critical information about their breathing status. Note the following:

Respiratory Rate and Pattern: Count the breaths per minute. Is the rate too fast (tachypnea), too slow (bradypnea), or irregular? Note the depth and rhythm of breaths. Are they shallow, gasping, or labored?
Work of Breathing: Observe the child's effort. Are they using accessory muscles (neck, intercostal muscles)? Is there nasal flaring, grunting, or retractions (sunken areas between the ribs or above the clavicles)?
Mental Status: A child's level of consciousness is directly related to their oxygenation. Are they alert and responsive, lethargic, or unresponsive?
Skin Color: Note the color of the child's skin, lips, and nail beds. Cyanosis (bluish discoloration) is a sign of poor oxygenation.
Positioning: How is the child positioned? Are they sitting upright, tripod position (leaning forward with hands on knees), or lying supine? The position they choose can indicate respiratory distress.

2. Auscultation: Listening to the Lungs

Next, use a stethoscope to listen to the child's lungs. This will help identify sounds that might indicate underlying conditions:

Breath Sounds: Are the breath sounds clear and equal bilaterally, or are there wheezes, crackles, or diminished breath sounds? Wheezes suggest airway narrowing, crackles might indicate fluid in the lungs, and diminished sounds may indicate pneumothorax or other lung pathology.
Location of Sounds: Carefully note the location of any abnormal sounds. This helps pinpoint the area of the lung that is affected.

3. Pulse Oximetry: Measuring Oxygen Saturation

Non-invasive pulse oximetry measures the percentage of oxygen saturation (SpO2) in the blood. While not a direct measure of breathing, it's an essential indicator of how well the lungs are oxygenating the blood. Aim for an SpO2 above 95%.

4. Capnography (EtCO2): Monitoring End-Tidal Carbon Dioxide

Capnography measures the end-tidal carbon dioxide (EtCO2), the concentration of carbon dioxide in the exhaled breath. This provides valuable information about ventilation and perfusion. Normal EtCO2 levels are typically between 35-45 mmHg.

Addressing Common Breathing Challenges in PALS

What is the most common cause of respiratory distress in children?

Bronchiolitis, a lower respiratory tract infection affecting the small airways (bronchioles), is a frequent cause of respiratory distress in infants and young children. It often presents with wheezing, cough, and increased work of breathing.

How to Recognize and Manage Respiratory Failure in Children?

Respiratory failure is a serious condition requiring immediate intervention. Signs include:

Decreased level of consciousness
Significant respiratory distress (severe retractions, gasping, cyanosis)
Low SpO2 despite supplemental oxygen
Bradycardia

Management involves providing supplemental oxygen, ventilatory support (bag-valve mask or mechanical ventilation), and addressing any underlying causes.

Conclusion

A thorough PALS breathing assessment is crucial for identifying and managing respiratory problems in children. By systematically evaluating visual cues, auscultating lung sounds, and monitoring oxygen saturation and EtCO2, healthcare providers can rapidly assess the severity of respiratory compromise and initiate appropriate interventions. Remember, early recognition and intervention are key to improving patient outcomes in these critical situations.
