CTAB stands for Clear To Auscultation Bilaterally.
What does CTAB mean?
CTAB stands for Clear To Auscultation Bilaterally, a normal finding meaning both lungs sound clear when listened to with a stethoscope.
CTAB stands for Clear To Auscultation Bilaterally. It is a normal finding recorded during a chest examination. Auscultation means listening with a stethoscope, and bilaterally means on both sides. So CTAB means that both lungs sound clear, with no abnormal sounds such as crackles, wheezes, or reduced air entry.
Recording CTAB is a quick, reassuring way to document that the lungs sound healthy. If abnormal sounds were heard, the clinician would note those instead, as they can point to problems such as infection, fluid, or narrowed airways.
CTAB is a very common shorthand in the respiratory part of a physical examination. It is closely related to CTA (clear to auscultation), with the added detail that both sides are clear.
When is CTAB used?
Recorded during chest examination to note that both lungs sound clear with no abnormal sounds.
