where do you hear crackles in the lungs
Crackles Basal or basilar crackles (not to be confused with the basilar artery of the brain) are crackles apparently originating in or near the base of the lung. Bibasal or bibasilar crackles refer to crackles at the bases of both the left and right lungs. Bilateral basal crackles also refers to the presence of basal crackles in both lungs.
Heart sounds Splitting of S2, also known as physiological split, normally occurs during inhalation because the decrease in intrathoracic pressure increases the time needed for pulmonary pressure to exceed that of the right ventricular pressure. A widely split S2 can be associated with several different cardiovascular conditions, including left bundle branch block, pulmonary stenosis, and atrial septal defect.
