The intercostal space (ICS) is the anatomic space between two ribs (Lat. costa). Since there are 12 ribs on each side, there are 11 intercostal spaces, each numbered for the rib superior to it. Since there are 12 ribs on each side, there are 11 intercostal spaces, each numbered for the rib superior to it.
The normal apex beat can be palpated in the precordium left 5th intercostal space, half-inch medial to the left midclavicular line and 3–4 inches left of left border of sternum. In children the apex beat occurs in the fourth rib interspace medial to the nipple.
Axillary lines. Vertical lines: Midline, lateral sternal line, parasternal line and midclavicular line. Horizontal lines: Level of the sternal angle, and zipho-sternal line. Anatomical "lines", or "reference lines," are theoretical lines drawn through anatomical structures and are used to describe anatomical location.
In addition, reference may be made to structures at specific levels of the spine (e.g. the 4th cervical vertebra, abbreviated "C4"), or the rib cage (e.g., the 5th intercostal space). Occasionally, in medicine, abdominal organs may be described with reference to the trans-pyloric plane, which is a transverse plane passing through the pylorus.
This should translate to the tube being inserted into the fifth intercostal space slightly anterior to the mid axillary line. [25] Chest tubes are usually inserted under local anesthesia. The skin over the area of insertion is first cleansed with antiseptic solution, such as iodine, before sterile drapes are placed around the area. The local ...
The V 5 ECG lead is placed on the anterior axillary line, horizontally even with V 4. The midaxillary line is a coronal line on the torso between the anterior and posterior axillary lines. It is a landmark used in thoracentesis, [2] and the V6 electrode of the 10 electrode ECG. The posterior axillary line is a coronal line on the posterior ...
The apex beat is found approximately in the fifth left intercostal space in the mid-clavicular line. It can be impalpable for a variety of reasons including obesity, emphysema, effusion and rarely dextrocardia. The apex beat is assessed for size, amplitude, location, impulse and duration.
The standard location for thoracostomy is the triangle of safety. This is an anatomical triangle. The borders of which are; the anterior border of the latissimus dorsi, the lateral border of the pectoralis major muscle, a line superior to the horizontal level of the nipple (or 5th intercostal space), with the apex being below, or at, the axilla.
