How to Document Heart and Lung Auscultation in a Healthy Adult
In a healthy adult, document heart sounds as "S1 and S2 normal, no murmurs, rubs, or gallops" and lung sounds as "clear bilaterally" or "normal breath sounds throughout all lung fields." 1
Heart Sound Documentation
For cardiac auscultation in healthy adults, your documentation should include:
- Heart sounds: Presence of normal first (S1) and second (S2) heart sounds
- Absence of abnormal findings: Explicitly state "no S3" (third heart sound), "no S4" (fourth heart sound), and "no murmurs" 1
- Heart rate and rhythm: Document whether the heart rate is regular or irregular 1
The standard format from ACC/AHA guidelines specifies documenting the presence or absence of:
- Third heart sound (S3) - mid-diastolic
- Fourth heart sound (S4) - late-diastolic
- Heart murmurs - if present, note timing (systolic/diastolic), quality, and intensity 1
In healthy adults, all of these should be documented as absent.
Lung Sound Documentation
For pulmonary auscultation, the ACC/AHA framework provides clear categories 1:
- "Clear" or "normal" - the appropriate documentation for healthy lungs
- Document the absence of:
- Rales (crackles)
- Decreased breath sounds or dullness
- Rhonchi
- Wheezing
- Other findings (pleural rub, etc.)
Critical Documentation Pitfalls
Avoid ambiguous symbols or drawings. Research demonstrates that doctors use at least 10 different drawing styles to represent lung sounds, with inconsistent meaning - for example, an "X" symbol was used to represent crackles in 60% of drawings but wheeze in 8% of drawings, and both findings in 13% 2. Use written descriptions instead of drawings unless you clearly label all symbols.
Complete Documentation Template
A comprehensive but concise entry for a healthy adult should include:
Cardiovascular: "Heart rate [X] bpm, regular rhythm. S1 and S2 normal. No S3, S4, murmurs, rubs, or gallops."
Pulmonary: "Respiratory rate [X] breaths/min. Lungs clear to auscultation bilaterally. No rales, rhonchi, wheezes, or decreased breath sounds."
This standardized approach ensures clear communication between clinicians and avoids the documented problems with ambiguous documentation that can lead to misinterpretation of clinical findings 2. The preanesthesia evaluation guidelines emphasize that at minimum, a focused physical examination should include assessment of the airway, lungs, and heart with documentation of vital signs 3.
