What is the difference between a pneumothorax and a tension pneumothorax?

Pneumothorax is when air collects in between the parietal and viscera pleurae resulting in lung collapse. It can happen secondary to trauma (traumatic pneumothorax). When mediastinal shifts accompany it, it is called a tension pneumothorax.

How can you tell the difference between an open tension pneumothorax?

The air accumulation can apply pressure on the lung and make it collapse. Pneumothoraces can be even further classified as simple, tension, or open. A simple pneumothorax does not shift the mediastinal structures, as does a tension pneumothorax. An open pneumothorax also is known as a “sucking” chest wound.

What are the two signs of a tension pneumothorax?

Tension Pneumothorax

• Symptoms include chest pain, shortness of breath, rapid breathing, and a racing heart, followed by shock.
• Doctors can usually diagnose tension pneumothorax based on the person’s history, symptoms, and examination results.
• Doctors immediately insert a large needle into the chest to remove the air.

What is seashore sign?

This M-mode image demonstrates a linear, laminar pattern in the tissue superficial to the pleural line (arrow) and a granular or “sandy” appearance deep to the pleural line. This phenomenon, known as the “seashore sign” indicates normal lung sliding and excludes pneumothorax at this interspace.

How do you reverse tension pneumothorax?

Treatment of tension pneumothorax is immediate needle decompression by inserting a large-bore (eg, 14- or 16-gauge) needle into the 2nd intercostal space in the midclavicular line. Air will usually gush out.

Can a tension pneumothorax heal itself?

On some occasions, a collapsed lung can be a life-threatening event. Treatment for a pneumothorax usually involves inserting a needle or chest tube between the ribs to remove the excess air. However, a small pneumothorax may heal on its own.

How do you relieve tension pneumothorax?

What is the early signs of tension pneumothorax?

Symptoms of Tension Pneumothorax At first, people have chest pain, feel short of breath, breathe rapidly, and feel that their heart is racing. As the pressure inside the chest increases, blood pressure drops dangerously low (shock ), people feel weak and dizzy, and the veins of the neck may bulge.

What is a deep sulcus sign?

The deep sulcus sign (1) is seen on chest radiographs obtained with the patient in the supine position. It represents lucency of the lateral costophrenic angle extending toward the hypo- chondrium. The abnormally deepened lateral costophrenic an- gle may have a sharp, angular appearance (Figure).

Can pneumothorax be seen on ultrasound?

Sonographic signs, including ‘lung sliding’, ‘B-lines’ or ‘comet tail artifacts’, ‘A-lines’, and ‘the lung point sign’ can help in the diagnosis of a pneumothorax. Ultrasound has a higher sensitivity than the traditional upright anteroposterior chest radiography (CXR) for the detection of a pneumothorax.

When do you decompress a tension pneumothorax?

If the patient has either a closed or open tension pneumothorax, then the need for a needle decompression is required to save the patient. A needle decompression involves inserting a large bore needle in the second intercostal space, at the midclavicular line.

Is the comet tail artifact a pneumothorax sign?

The comet-tail artifact: an ultrasound sign ruling out pneumothorax Ultrasound detection of the “comet-tail artifact” at the anterior chest wall allows complete pneumothorax to be discounted. Ultrasound detection of the “comet-tail artifact” at the anterior chest wall allows complete pneumothorax to be discounted.

What’s the difference between a pneumothorax and a tension lung?

A tension pneumothorax is similar to a pneumothorax, where there is a hole in the pleural space and air accumulates around the lung, causing the lung to collapse. But during a tension pneumothorax, air CANNOT escape the pleural space. Instead it gets trapped inside, putting immense pressure on the lungs, heart and blood vessels.

When to use M mode to detect pneumothorax?

Absence of normal comet tail or reverberation artifacts: This artifact arising from the deeper visceral pleura should normally move with the lung during respiration and is absent when air or pneumothorax is present “Stratosphere” or “Bar Code” sign: M mode detects the difference in motion between the two pleural lines.

Can a sliding lung be a sign of pneumothorax?

The bilateral, anterior discovery of sliding lung is sufficient to rule out pneumothorax in the vast majority of cases. Bilateral absence of B-lines/comet tail artifacts from the pleura with loss of the lung pulse and sliding, and subsequent discovery of a lung point in a typical location is quite specific for the presence of a pneumothorax.
