Where do you listen first when auscultating lungs?
What is the order for Auscultating breath sounds?
- While the patient breathes normally with mouth open, auscultate the lungs, making sure to auscultate the apices and middle and lower lung fields posteriorly, laterally and anteriorly.
- Alternate and compare sides.
- Use the diaphragm of the stethoscope.
- First listen with quiet respiration.
How do you check lung sounds?
listen to anterior thorax breath sounds beginning above clavicles. listen to lateral thorax breath sounds. stand behind the patient. Instruct the client to raise arms. Listen to posterior thorax breath sounds beginning the apex of lungs. compare breath sounds over the right & left sides of the posterior thorax.
Where should you hear bronchial breath sounds?
Bronchial breath sounds can be described as hollow or tubular sounding and are only heard anteriorly, mainly over the tracheal area. Inspiration is slightly shorter than expiration with a distinct pause in between. The landmark for checking bronchial breath sounds is at the middle of the throat where the clavicles meet.
What causes tight lung sounds?
They can be caused by:
- Pneumonia
- Heart disease
- Pulmonary fibrosis
- Cystic fibrosis
- COPD
- Lung infections, like bronchitis
- Asbestosis, a lung disease caused by breathing in asbestos
- Pericarditis, an infection of the sac that covers your heart

Where can you hear pleural rubs?
Often the sound of pleural rubs can be localized to a specific location in the lung and chest area . Pleural friction rub sounds can be continuous or broken and will be heard every time the patient takes a breath. (This is a predominately inspiratory low frequency sound.
What is the sound of a wheezing lung?
Wheezing lung sounds are one of the easier to identify breath sounds for EMTs and paramedics. The wheezing sound can be heard during inhalation or exhalation and it’s caused by a narrowing of the airways. Wheezing lung sounds are continuous and can be heard throughout the lungs.
What is crackles lung?
Crackles Lung Sounds. Crackles lung sounds can be trickier for EMTs and paramedics than other adventitious lung sounds for a variety of reasons. Crackles lung sounds can be categorized both by the sound quality and when they are heard in the respiratory cycle.
Why are rhonchi and stridor all lung sounds?
Wheezing, rhonchi, stridor, crackles and pleural friction rub are all adventitious lung sounds because you will hear extra noises in the airways during the assessment. Absent and diminished breath sounds are also abnormal, but they are not considered to be adventitious lung sounds.
Why do children make a stridor sound?
Stridor lung sounds are frequently heard in children and are caused by something blocking the larynx. Stridor breathing is continuous and tends to be one of the easier adventitious lung sounds for EMTs to recognize.
How to tell if a stethoscope is pleural friction rub?
An easy way to figure out the difference is by having the patient hold their breath while you listen with your stethoscope. If you can still hear the rubbing sound, than it’s the heart and not a pleural friction rub. Often the sound of pleural rubs can be localized to a specific location in the lung and chest area. Pleural friction rub sounds can be continuous or broken and will be heard every time the patient takes a breath.
Why is it so hard to read a patient's breath?
EMTs and paramedics in the field may find it especially difficult to assess a patient’s breath sounds because of the noisy environment and constant movement. There are steps you can take to make sure you get the best reading every time you place your stethoscope and listen to a patient’s lung field.
What do you hear when you take a deep breath?
During a deep breath you will hear other adventitious lung sounds, such as a cardiac wheeze, crackles, rhonchi and rhales. Or, better yet, the air movement will be good with no adventitious sounds.
Why do I hear rhonchi when I breathe?
This is because the deep breath causes more turbulence and this may knock secretions around.
What happens if you hear a wheeze in your throat?
If you hear a wheeze, particularly one that is audible or present with good air movement, you should then proceed to listen to the throat. If you hear a wheeze in the throat you do not have bronchospasm, but a throat wheeze (stridor) that is radiating throughout the lungfields.
What does it mean when you hear crackles during a respiration?
And, if you hear crackles during normal respirations, chances are what you are hearing is secretions or fluid as opposed to fine inspiratory crackles.
Can you rule out bronchospasm?
However, you still cannot rule bronchospasm out.
Is it good to have the same air flow on both sides of the lungs?
Equal air movement: If the air flow is the same on both sides of the lungs this is good. If airflow is diminished on the right and normal on the left, then you know you have some disease process going on and it's up to you and the doctor to determine what it is.
Can you listen to a stethoscope on your back?
I notice a lot of nurses and doctors will tell you to take in a deep breath for each place the stethoscope is placed on your back. While this is a good method of hearing adventitious lung sounds, it's not the best way to listen.
What are the sounds of the lung?
Identify adventitious lung sounds. Adventitious or extra lung sounds consist of rales, rhonchi, stridor and wheezing. Rales are also known as crackles. They are high-pitched and discontinuous. They make a clicking, bubbling or rattling sound and occur when air opens closed air spaces. They produce a sound somewhat like what rubbing your hair between your fingers does. Rales can sound dry or moist, fine or coarse. Rhonchi lung sounds resemble snoring, according to the Medline Plus website. Air that is blocked or travels roughly through large airways makes these sounds. Rhonchi sounds can also sound like gurgling reports Rathe. Wheezes are high-pitched sounds heard during exhalation. Narrowed airways produce wheezing sounds. Stridor is a type of wheeze heard during inspiration. It is caused by blockage of airflow in the trachea or back of the throat.
What are the sounds that are louder in the airways?
Interpret your findings. Larger airways emit louder and more high-pitched the sounds according to Stritch School. Bronchial sounds are high-pitched, inspiration and expiration are of equal length and a pause should be heard between inspiration and expiration. Vesicular sounds are normally low-pitched and inspiration is normally longer than expiration and you should hear no pause between inspiration and expiration. Breath sounds are louder at lower position. If you hear bronchial breathing in abnormal spots, no ventilation is passing into alveoli. This may be due to alveolar atelectasis, cavitation, consolidation, pleural effusion, pneumothorax or a mass.
How to use a stethoscope on the back?
Place the stethoscope in 12 places along the back, switching from the left side to the right in a symmetrical fashion. Start at the bottom and work your way up. Listen to lung sounds at eight places along the middle back, under the scapula bones, from the outer rib cage inwards in two tiers of four. Listen to lung sounds between the scapula bones at their lower portion on either side of the spine. Listen to lung sounds below the base of the neck on both sides of the spine.
What is the process of listening to the sounds inside the body?
Auscultation refers to the process of listening to the sounds inside the body, including the lungs, to diagnose problems. Using a stethoscope, a doctor can listen to bronchial and vesicular breathing. Bronchial breathing can be heard along the trachea and under the collarbone through the chest or under the shoulder through the back, according to the Stritch School of Medicine at Loyola University. Vesicular breathing can be heard all along the back and chest where the lungs reside.
How to warm a stethoscope?
Warm the stethoscope by rubbing the metallic portion before using it on the patient. Try to visualize underlying anatomy as you ascultate. Listen to recordings of abnormal and normal lung sounds.
How to ascultate chest?
Ascultate the chest from side to side and top to bottom in 12 spots, recommends Rathe. Listen to lung sounds down four spots on each side of the chest beginning at the collarbone and ending at the breast or pectoral muscle. Listen to two spots on the outer sides of the rib cage below the breast bone.
How to identify pleural friction rubs?
When the inflamed and roughened pleural membranes stick together, the patient stops breathing for a moment because of pain. As the membranes pull apart and slip past each other, a sound like leather-on-leather may be heard during both inhalation and exhalation. This is a pleural friction rub, reports East Tennessee State University (ETSU). Whispered sounds are not heard through the chest wall normally according to ETSU. If you ask the patient to whisper a word and you hear it through the stethoscope when it is place on the chest wall, fluid buildup in the lung is transmitting the sound clearly. This is known as whispered pectorloquy.
Where does inspiratory sound originate?
Thus in health, over most of the chest, the breath sounds are low-pitched and have a relatively quiet expiratory phase.[1] The inspiratory component originates in the lobar and segmental airways, whereas the expiratory component arises from more central airways. [3] They are soft, low pitched, and rustling in quality.
How many characters are in breath sound?
Breath sound have three characters; frequency, intensity, and quality; which helps us to differentiate two similar sounds.
What is the term for the voice over a consolidated lung?
The term used to describe the voice sounds heard over consolidated lung is bronchophony (also called vocal resonance). It can be determined through the stethoscope when the patient says “99”, usually just audible but becoming louder when the lung is consolidated. Pectoriloquy is abnormal transmission of the patient’s voice sounds through the chest wall so that they can be clearly heard through the stethoscope. The term used to describe whispered speech heard over consolidated lung (as in pneumonia), is whispering pectoriloquy. Bronchophony and whispering pectriloquy have the same implications as bronchial breathing i.e. consolidation or cavitation of the lung with improved transmission of sound. Aegophony is a form of bronchophony in which the spoken syllables have a peculiar nasal or bleating quality, and these arise from the transmission of sound through compressed lung just above a pleural effusion.
What is a grating sound?
A discontinuous grating sound or creak in phase with breathing that occurs in the presence of pleural inflammation. Friction rubs are heard better when the stethoscope is applied firmly to the chest wall. Pleural rubs must be distinguished from similar sounds produced by movement of the scapula, ribs and thoracic musculature under the stethoscope. The latter disappear on repositioning of the stethoscope, changing pressure of application to the chest wall or by repositioning of the patient.
What is a pleural rub?
Pleural rubs must be distinguished from similar sounds produced by movement of the scapula, ribs and thoracic musculature under the stethoscope. The latter disappear on repositioning of the stethoscope, changing pressure of application to the chest wall or by repositioning of the patient.
What is a monophonic wheeze?
Monophonic wheezing consists of a single musical note starting and ending at different times. A local pathology-like bronchial obstruction by tumor, bronchostenosis by inflammation, mucus accumulation, or a foreign body can produce this sound. In case of rigid obstruction, the wheeze is audible throughout the respiratory cycle, and when the obstruction is flexible, wheeze may be inspiratory or expiratory.
What is the name of the procedure that a physiotherapist uses to diagnose pulmonary disease?
It is performed using a stethoscope.
What tests are needed for a heart murmur?
Other tests are essential to obtain a firm diagnosis and examine further. Most likely, these other tests include the electrocardiogram (ECG) and echocardiography.
Where is the stethoscope located?
A doctor places a dual head stethoscope at the lungs’ apex above the clavicle. The diaphragm helps to detect low-pitched sounds across the chest part. Normal sounds of the lungs occur in all parts of the chest area, including the rib cage’s bottom and right above the collarbones.
Who developed the technique of listening?
The act of listening is called auscultation, and it was the Czech doctor and professor Josef Skoda who developed the techniques for this, techniques that are still used today.
Is a stethoscope a medical device?
Surely you have ever seen a stethoscope in your family doctor’s office. It is a cheap, non-invasive, and easy-to-use device. It is one of the most common tools in medical practice and it is used to examine the respiratory and cardiovascular systems (that is, the lungs and the heart).
