Why we #pocus: unexpected complications and daily changes. A thread.
70 year old male presented with hypoxic respiratory failure. Initially diagnosed with bilateral pneumonia and started on zosyn. Very hypoxic requiring 15L. The following morning #pocus revealed:
Large bilateral pleural effusion a with compression atelectasis. Clinically was never pneumonia. Was upgraded to ICU and intubated. R sided thoracentesis drained 1.8L of fluid and was stepped out of ICU
The following morning lung #pocus exam done. Left lung: lung sliding with diffuse lung rockets consistent with pulmonary edema
Left lung M-Mode: Sandy Beach sign consistent with normal lung sliding
R lung anterior: A lines present but NO lung sliding
M- mode of R lung: barcode sign consistent with pneumothorax.
Couldn't find lung point so got CT to confirm:
This was a clear and excellent example of how #pocus helps patients and saves them from complications. This patient had other reasons to be hypoxic so pneumothorax was not on the differential initially. But post thoracentesis this is always a concern.
Chest x-rays miss up to 60% of lung consolidations. Especially if they are retro-cardiac.
#pocus misses about 5% if you do a full exam.
Here is a good example with a corresponding left lower posterior lobe ultrasound taken with @ButterflyNetInc IQ3
Chest X-ray was clear but pocus shows DENSE left lower lobe consolidation with static air bronchograms!
Here is the same consolidation 3 days later after antibiotics via the @ButterflyNetInc IQ3 again:
It has shrunken considerably! #pocus is far better than chest X-ray for lung pathology. And it allows for daily evaluation to note disease process response to treatment!

Reason # 76587 why lung #pocus is important: it can often give more information than CXR or CT Chest can. Case in point:
Elderly female on methotrexate and prednisone presenting with fever and cough.
Initial CXR:
Read as "Bibasilar atelectasis." She was started on antibiotics. The following morning had abdominal pain and CT chest abdomen and pelvis ordered. CT chest seen here:
Grossly does not look too impressive. Radiologist read it as "no consolidations, scattered linear opacities." That afternoon seen by a physician skilled in lung #pocus. Left lung lateral lung seen here
Most glaring is the size of the aorta. It is clearly larger than the left atrium. Also notable is the anterior leaflet of the mitral valve isn’t opening much.
