How to Chart Wheezing
When documenting wheezing in a patient, chart it as a clinical finding characterized by a raspy high-pitched whistling sound noted on expiration or inspiration associated with obstruction of the lower airways. 1
Key Elements to Document When Charting Wheezing
Timing and Pattern
- Document when the wheeze occurs in the respiratory cycle:
- Expiratory only
- Inspiratory only
- Biphasic (both inspiratory and expiratory) - note that biphasic wheezing is typically associated with more severe obstruction 2
- Duration within respiratory phase (early, late, or throughout entire phase)
Characteristics
- Pitch: Document as high, medium, or low pitch
- Intensity/Loudness: Document as mild, moderate, or severe
- Distribution: Document location where wheezing is heard (e.g., diffuse, localized to specific lung fields, unilateral, bilateral)
Associated Findings
- Document presence or absence of:
- Accessory muscle use
- Respiratory distress
- Cyanosis
- Tachypnea
- Reduced oxygen saturation
- Other adventitious lung sounds (crackles, rhonchi)
Quantification
- Consider using a scale to quantify wheezing severity:
- 0 = No wheezing
- 1 = Mild wheezing (end-expiratory)
- 2 = Moderate wheezing (throughout expiration)
- 3 = Severe wheezing (audible without stethoscope, inspiratory and expiratory)
Response to Interventions
- Document any changes in wheezing after interventions:
- Response to bronchodilators
- Response to positioning
- Response to coughing or deep breathing
Example Documentation Format
Respiratory: Lungs with [mild/moderate/severe] [high/medium/low]-pitched [inspiratory/expiratory/biphasic] wheezing [throughout/early/late] [inspiration/expiration], [diffuse/localized to (specific area)]. [With/without] accessory muscle use. Respiratory rate [number] breaths per minute. O2 saturation [percentage] on [room air/oxygen delivery method]. Wheezing [improved/worsened/unchanged] after [intervention].Common Pitfalls to Avoid When Charting Wheezing
Confusing wheezing with other adventitious sounds: Stridor is a high-pitched sound heard primarily on inspiration and indicates upper airway obstruction, while wheezing typically indicates lower airway obstruction 3.
Failing to document response to treatment: Always document whether wheezing improves, worsens, or remains unchanged after bronchodilator administration or other interventions.
Assuming all wheezing is asthma: While asthma is a common cause, wheezing can result from various conditions including COPD, bronchiolitis, heart failure, foreign body aspiration, and malignancy 4.
Inadequate characterization: Detailed characterization of wheezing correlates with severity of airway obstruction. High-pitched, loud wheezing that spans the entire respiratory phase typically indicates more severe obstruction 2.
Relying solely on subjective assessment: When possible, include objective measurements like peak expiratory flow rate (PEFR) or spirometry values alongside wheezing description 2.
By following this structured approach to documenting wheezing, you'll provide a comprehensive clinical picture that aids in diagnosis, treatment decisions, and monitoring of respiratory conditions over time.
