This is jugular venous distension (JVD) seen with #POCUS. But how can we quantify it at the bedside?

Using the Istrail Method described in The POCUS Textbook, we can estimate the actual right atrial pressure to within about 3 mmHg.

@nephrop @IM_Crit_ @pocuspeek Once JVD is discovered, the next step is to slide the probe up the neck to find the collapse point. The vertical distance from the base of the neck to the collapse point is measured. This can best be done at the bedside using your outstretched fingers.

Measure and memorize the height of your outstretched fingers, and this can act as your bedside ruler.

This will give you the pressure in centimeters of water of the visible portion of the jugular vein.Image

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:

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:

Reason # 67543 why #pocus is important: sometimes mild symptoms are a sign of impending disaster.

41 year old thin athletic male presented to the hospital with a few weeks of mild shortness of breath with exertion.

BP 170/70, HR 100. CXR with cardiomegaly, tortuous aorta. Bedside #pocus exam shown below:

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 JVP exam has been with us since 1930 when Sir Thomas Lewis first proposed this exceptionally clever technique. A #pocus thread. Image He knew that in heart failure there in “congestion of the veins” and when they become engorged can be detected on the neck.
