Shadow Health Respiratory Concept Lab with complete solution Detail normal air passage when a patient breathes. Answer- air rushes through nasal passages and trachea, bronchi , & into lungs where it’s absorbed by the alveoli What happens during auscultation? Answer- Healthcare professional listen to the heart sounds through a stethoscope What are bronchial sounds and how are these sounds detected? Answer- Harsh, high-pitched, & loud sound that can be heard above the manubrium (over the trachea). What are bronchovesicular sounds and how are these sounds detected? Answer- Medium in loudness & pitch sounds that can be heard over the main bronchi What are vesicular sounds and how are these sounds detected? Answer- The softest and lowest in pitch sounds that are heard over the lower bronchi, bronchioles, and lobes Lungs Lobes Answer- Where are vesicular sounds normally heard? Answer- peripheral lung tissue Decreased breath sounds Answer- occur in airway disease or obstruction, diaphragm paralysis, or impairment of sound transmission through the chest wall worsening symptoms may lead to absent breath sounds. Absent lung sounds usually indicate that no air is moving in the lung tissue. Increased breath sounds Answer- a

Respiratory Concept LabWhen your patient breathes, air rushes through the nasal passages & trachea, the bronchi, & into the lungs where it’s absorbed by the alveoli. Healthcare professionals listen to these sounds through a stethoscope – a process called auscultation. Once you know how to listen to these sounds, they can give you diagnostic information about your patient’s respiratory system. Normal Lung SoundsBronchialoYou can hear bronchial sounds above the manubrium, over the trachea. oBronchial sounds are:HarshHigh-pitchedLoud BronchovesicularoThese sounds are heard over the main bronchi. oThese sounds are:Medium in loudnessMedium in pitchVesicularoThese sounds are heard over the lower bronchi, the bronchioles, & the lobes. oThe left lung has two lobes. The right has three lobes.oVesicular sounds are:SoftestLowest in pitchAbnormal Lung SoundsDecreased Breath SoundsoNormal lung sounds are usually easy to hear with a stethoscope. Occasionally you will hear sounds that are decreased in intensity, or even absent. oDecreased breath sounds occur in airway disease or obstruction, diaphragm paralysis, or impairment of sound transmission through the chest wall.oWorsening symptoms may lead to absent breath sounds. Absent lung sounds usually indicate that no air is moving in the lung tissue. Increased Breath SoundsoLocation of breath sounds matters!oA “normal sound” is not normal if it is in the wrong place.oA common abnormal finding is hearing bronchial or bronchovesicular sounds, which are louder and harsher, in peripheral lung tissues where vesicular sounds are normally heard. This occurs when underlying lung tissue is filled with liquid orsolid material, rather than air.
Adventitious Sound soWhen you auscultate, you might hear abnormal sounds in additions to the normal lung sounds. These additional abnormal sounds are called adventitious sounds.oCrackles (Fine)Fine crackles, as the name indicates, are high-pitched crackling sounds that occur when inhaled air meets deflated alveoli, causing them to pop open. Short popping soundsHigh-pitchedLocation: usually bases of lower lobesTIP: Fine crackles sound like the noise created by rolling a strand of hair between your thumb & index finger.The existence of fine crackles in a vesicular region is a likely indicator of pneumonia – an inflammatory condition of the lung usually caused by an infection. Pneumonia is a major cause of death among all age groups, resulting in 4 million deaths (7%) of the world’s total death) yearly. Crackles (Coarse)Coarse crackles are loud, low-pitched bubbling sounds that are caused when air meets secretions in the large airways.Short crackling soundsLow-pitchedLocation: Trachea & large bronchiTIP: Coarse crackles sound like separating a Velcro fastener.oRhonchiRhonchi are continuous, low-pitched snoring sounds caused by airway obstruction from thick secretions, muscular constriction, or masses. Long snoring soundsLow-pitchedLocation: BronchiTIP: Rhonchi can sound like snoring or moaning.oWheezesWheezes are continuous, high-pitched musical sounds that are created bythe narrowing of airways from swelling, secretions, or masses.Long musical soundsHigh-pitchedLocation: all lung fieldsoStridorStridor is a loud, continuous, high-pitched crowing sound that is caused by upper airway obstruction.This is the most serious of the adventitious sounds & it requires immediate attention
Long crowing soundsHigh-pitchedLocation: trachea TIP: Stridor is usually audible without a stethoscope
