The Pediatric Advanced Life Support (PALS) course emphasizes a systematic approach to assessing and managing pediatric emergencies. A crucial component of this approach is the breathing assessment. Accurate and timely assessment of a child's breathing is critical for determining the appropriate intervention and improving patient outcomes. This article will thoroughly detail the components of the breathing assessment within the PALS framework.

Initial Assessment: The ABCs of PALS

Before delving into the specifics of breathing assessment, remember the foundational principle of PALS: the ABCs – Airway, Breathing, and Circulation. While this article focuses on "Breathing," it's crucial to understand that airway patency is paramount and must be addressed first. A compromised airway will always take precedence.

Key Components of the PALS Breathing Assessment

The PALS breathing assessment goes beyond simply observing if a child is breathing. It involves a detailed evaluation of several key elements:

1. Appearance

The child's overall appearance provides important clues about their respiratory status. Look for:

Level of Consciousness: Is the child alert, responsive, or lethargic? Decreased consciousness can indicate hypoxia.
Work of Breathing: Observe the effort the child is expending to breathe. Look for retractions (inward pulling of the chest wall), nasal flaring, head bobbing, grunting, and use of accessory muscles (e.g., abdominal muscles). Increased work of breathing signifies respiratory distress.
Skin Color: Assess for cyanosis (bluish discoloration), pallor (pale skin), or mottling (patchy discoloration). Cyanosis, especially around the mouth and extremities, indicates poor oxygenation.
Position: Note the child's position. Children in respiratory distress often assume a tripod position (leaning forward with hands on knees or a surface) to facilitate breathing.

2. Airway

While airway patency is addressed initially, reassessment is continuous. Consider:

Patency: Is the airway clear and unobstructed? Look for foreign bodies, secretions, or anatomical abnormalities.
Sounds: Listen for unusual sounds like stridor (high-pitched sound during inhalation indicating upper airway obstruction) or wheezing (high-pitched whistling sound during exhalation suggesting bronchospasm).

3. Breathing Rate and Pattern

Rate: Count the respiratory rate for one full minute. Normal respiratory rates vary by age; deviations from the norm indicate potential problems. A rapid respiratory rate (tachypnea) suggests respiratory distress or acidosis. A slow respiratory rate (bradypnea) can indicate serious conditions like hypoxia or neurological issues.
Rhythm: Is the respiratory rhythm regular or irregular? Irregular rhythms may signify underlying cardiac or neurological issues.
Depth: Observe the depth of each breath. Shallow breaths indicate inadequate ventilation.
Effort: As previously mentioned, assess the effort required for each breath.

4. Breath Sounds

Auscultate the lungs bilaterally, comparing breath sounds on both sides. Listen for:

Presence: Are breath sounds present and equal bilaterally? Absence of breath sounds in one area could indicate pneumothorax (collapsed lung) or other conditions.
Quality: Are the breath sounds clear, diminished, or wheezy? Diminished breath sounds can indicate atelectasis (collapsed lung) or pleural effusion (fluid in the pleural space). Wheezes suggest bronchospasm (asthma or bronchiolitis).
Additional Sounds: Listen for crackles (fine or coarse), which may indicate pneumonia or pulmonary edema. Rhonchi (low-pitched sounds) suggest secretions in the larger airways.

5. Oxygen Saturation

Use pulse oximetry to measure the percentage of hemoglobin saturated with oxygen (SpO2). While a helpful tool, remember that pulse oximetry can be inaccurate in certain situations (e.g., poor peripheral perfusion). Always correlate the SpO2 reading with the clinical picture. A low SpO2 indicates hypoxemia (low blood oxygen).

Integrating the Assessment Findings

The PALS breathing assessment isn't about individual components in isolation; it's about integrating all the findings to form a holistic picture of the child's respiratory status. This integration guides the choice of appropriate interventions.

Remember, timely and accurate assessment is vital in pediatric emergency care. Continuous monitoring and reassessment are crucial, as a child's condition can change rapidly. Thorough understanding and application of the PALS breathing assessment components are essential for providing optimal patient care.
