Lung sliding is seen in A, and lung pulse is seen in B

Lung point

Which of the following statements about lung point are correct? Select all that apply.

Absence of lung-sliding, B-lines AND lung pulse together with presence of a 'lung point' are diagnostic for PTX
A is a PTX – ultrasound image of pleural air below the transducer beam
C is a PTX – ultrasound image of pleural air below the transducer beam
A lung point is present when inspiration brings the normal lung signs into view and it disappears with expiration
B is skin and intercostal tissue
A lung point is present at the interface between a pneumothorax and the normal pleura

Use of lung ultrasound signs in PTX

Which of the following statements about lung ultrasound signs are correct? Select all that apply.

Absence of lung sliding and B-lines, but presence of lung pulse indicates a PTX
Presence of the "stratosphere sign" in an M-mode recording confirms a PTX
Absence of lung sliding, B-lines and lung pulse together with the presence of a lung-point confirms a PTX
The presence of a lung-point in a stable patient always calls for chest tube insertion
Absence of lung sliding, lung pulse and B-line(s) in a stable patient calls for immediate chest tube insertion
Lung pulse rules out the presence of a PTX

Causes of the interstitial syndrome

Examine the image and select which of the statements below are correct. Select all that apply.

The interstitial syndrome may be seen in patients with non-cardiogenic pulmonary edema
The interstitial syndrome may be seen in patients with COPD exacerbation only
The interstitial syndrome may be seen in patients with interstitial lung disease
The interstitial syndrome may be seen in patients with ARDS
The interstitial syndrome may be seen in patients with cardiogenic pulmonary edema
The interstitial syndrome may be a normal finding

B-lines and interstitial syndrome

Examine the video clip and select which of the statements below are correct. Select all that apply.

B-lines do not move in synchrony with lung sliding
B-lines are a reverberation artefact
In interstitial syndrome, multiple B-lines are present in 1 or more of the anterior or lateral zones bilaterally
In interstitial syndrome, multiple B-lines are present in 2 or more of the anterior or lateral zones bilaterally
The use of harmonics software generally improve the appearance of B-lines on the US screen
The interstitial syndrome can be seen in isolated severe asthma exacerbation
