At the 4th intercostal space you will be assessing the right middle lobe and the left upper lobe. Then midaxillary at the 6th intercostal space you will be assessing the right and left lower lobes.
Is the 2nd intercostal space below the 2nd rib?
Intercostal spaces are numbered respectively to the superior rib, i.e. second intercostal space is below the second rib. Lower ribs articulate with the sternum indirectly. It is hard to palpate lower ribs and intercostal spaces close to the sternum. Physician has to palpate in inferior and lateral direction.
Where is the second rib located?
The second rib attaches to the sternum at the sternal angle. Since the first rib is hidden behind the clavicle, the second rib is the highest rib that can be identified by palpation. Thus, the sternal angle and second rib are important landmarks for the identification and counting of the lower ribs.
Where is the intercostal space located?
Intercostal spaces lie between adjacent ribs and are filled by intercostal muscles (Fig. 3.26). Intercostal nerves and associated major arteries and veins lie in thecostal groove along the inferior margin of the superior rib and pass in the plane between the inner two layers of muscles.
What is located at the second rib and fifth intercostal space?
Heart-on-a-chip More specifically, it is placed above the diaphragm at the front of the spinal column and behind the sternum and the ribs; the conically shaped organ stretches from the second rib toward the fifth intercostal space (Katz, 2010; Betts, 2013).
What are the first and second ribs?
The first rib is atypical because it is wide and short, has two costal grooves, and one articular facet. The second rib is thin, long, and has a tuberosity on its superior surface for the attachment of the serratus anterior muscle.

The most common ribs fractured are the 7th through 10th ribs. Fractures of the first and second ribs are rare but may be associated with serious damage to the brachial plexus of nerves, the subclavian vessels or associated with head, facial or thoracic aorta injuries.
What is second rib syndrome?
Tietze syndrome is characterized by mild to severe localized pain and tenderness in one or more of the upper four ribs. The second or third ribs are most often affected. In most people, the cartilage of only one rib is affected. A firm, spindle-shaped swelling occurs in the cartilage of the affected rib.
Where are the ribs on a woman?
Costal cartilage anchors them to the edge of the sternum, or breastbone, in the middle of the chest at the front of the body. These ribs attach to the thoracic vertebra of the spinal column in the back.
How many ribs does a woman have on her left side?
The Adam and Eve story has led some people to believe that men have one fewer rib than women. This isn't true. The vast majority of people have 12 sets, or 24 ribs, no matter their sex.
What is the intercostal space?
Contents. The Intercostal space (ICS) is the space in between the two adjacent ribs. There are 11 intercostal spaces on each side, each intercostal space is numbered for the rib superior to it. Every space consists of intercostal muscles and neurovascular bundle of intercostal plane. In each space, the vein is the most superior structure ...
What are the features of intercostal nerves?
They are segmental in character unlike the anterior primary rami from other regions of spinal cord which create nerve plexuses viz. cervical, brachial, lumbar and sacral.
What is the layer of connective tissue that separates the ribs and intercostal spaces?
Deep to the intercostal spaces and ribs, and separating such structures from the underlying pleura, is a layer of loose connective tissue, knowned as endothoracic fascia, which consists of variable amounts of fat. Superficial to the spaces are deep fascia, superfcial fascia, and skin.
How many intercostal arteries are there?
There are 11 pairs of intercostal arteries, one in each space. They supply the greater part of the intercostal spaces.
Which structure is the most superior in each space?
Every space consists of intercostal muscles and neurovascular bundle of intercostal plane. In each space, the vein is the most superior structure and is thus highest in the costal groove. The nervovascular bundle is in such a an order that vein is at the top, then the artery and then the nerve and they are generally not guarded by the groove.
Which space is restricted only upto the thorax?
The blood supply and nerve supply of 3rd-6th intercostal spaces is restricted only upto the thorax as a result of which these 3rd-6th spaces are typical intercostal spaces.
Where is the neurovascular bundle located?
Plane of neurovascular bundle in the intercostal space: The neurovascular bundle being composed of intercostal nerve and vessels is located between the internal intercostal and innermost intercostal muscles, i.e., between the intermediate and deepest layers of muscles.
Which space is used to assess the right and left upper lobes?
Then move to the 2nd intercostal space to assess the right and left upper lobes.
When listening to the posterior side of the chest, the arms need to be in the lap?
When listening to the posterior side of the chest the arms need to definitely be in the lap so the scapulae are separated . Use the diaphragm of the stethoscope to auscultate at various locations (see images below) Have patient breathe in and out through mouth slowly while listening.
What is the 2nd rib?
The 2nd rib is continuous with the sternal angle; slide your finger down to localize the 2nd intercostal space. The angle of Louis also marks the site of bifurcation of the trachea into the right and left main bronchi and corresponds with the upper border of the atria of the heart.
How many pairs of ribs are attached to each other?
The lower 5 ribs do not attach to the sternum. The 8th, 9th, and 10th ribs are attached to each other by costal cartilage.
What are anatomic landmarks?
Anatomic Landmarks. It is important to review the anatomy of the chest wall and thoracic cavity, as you will use anatomic landmarks to document the location of respiratory assessment findings. The thoracic cavity is made up of 12 pairs of ribs that connect in the posterior thorax to the vertebral bodies of the spinal column.

Heart Sounds and Murmurs
Murmurs are cause by turbulent blood flow. They are described in relation to the following heart sounds:
Auscultating Regions
Auscultation should be carried out in a systematic manner with the patient supine at a 30⁰ angle. Note that the diaphragm of the stethoscope should be used initially before repeating again with the bell to detect low-pitched murmurs.
Grading Murmurs
Murmurs are graded on a 6-point Levine scale based on their loudness and presence of a palpable thrill. It is important to note that the loudness of a murmur does not always correlate with the degree of valvular abnormality. A palpable thrill indicates that a murmurs should graded as at least a 4 out of 6.
How many cm needles are needed for ICS2?
Clemency et al [4] found that a 5cm needle is not sufficient at ICS2-MCL and to achieve a 95% decompression rate you would need a 6.4cm catheter, but did not assess alternative anatomic sites
What is the injury rate of ICS4 AAL?
Using a 8cm needle at ICS4-AAL aimed at a shallow angle of entry caused an injury rate of 32%
What is the rate of injury from a 5cm needle at ICS4-AAL?
Using a 5cm needle at ICS4-AAL at a shallow angle of entry caused a 1% rate of injury
Is ICS2 MCL decompression appropriate?
Regional variability in chest wall thickness may be partially explained by differences in BMI, thus in the USA and other western countries where BMI is higher, a change may be necessary in needle thoracostomy location or catheter length, but in other parts of the world, ICS2-MCL decompression may still be appropriate.
How many people correctly identified the second intercostal space?
Of the 14 who correctly identified the second intercostal space, 12 (86%) were positioned in the lower half of the intercostal space.
Is needle thoracocentesis life saving?
The use of a single human volunteer was an attempt to standardise the testing procedure; however, a range of volunteers may have given more useful results. Needle thoracocentesis for decompression of a tension pneumothorax is life saving, but is associated with potentially serious complications.
