POCUS echo isn't a formal echocardiogram — it's five views answering five questions: How's the squeeze? Is there fluid around the heart? Is the RV blown out? How full is the tank? Is a valve grossly wrong?
Learn the views in order. Every advanced cardiac application — including Echo for PE (No. 003) — is built on these windows.
Curated from the POCUS 101 Cardiac Ultrasound (Echocardiography) Made Easy: Step-By-Step Guide. Their view-by-view probe photos and labeled loops are the fastest way to build the mental model.
Small footprint fits between ribs. Cardiac preset — and note the screen indicator flips to the right side in cardiac mode.
Stand on the patient's right when possible: right hand drives the probe, left hand works the machine. Hold the probe like a pencil, hand anchored on the chest.
Left lateral decubitus swings the heart against the chest wall and clears lung out of the way — it rescues difficult parasternal and apical windows.
3rd–5th intercostal space at the left sternal border · indicator to the right shoulder
Your orientation view: RV in the near field, then LV, mitral valve, LA, and the aortic outflow in one plane. The descending aorta sits behind the LA — a key landmark for effusion vs. pleural fluid.
From PLAX, rotate ~90° clockwise · indicator toward the left shoulder · papillary muscle level
The LV in cross-section: a symmetric ring squeezing concentrically around its cavity, with both papillary muscles in view. Tilt the probe to sweep from base (mitral "fish mouth") to apex.
Probe at the PMI / inframammary fold · aim toward the right shoulder · indicator toward the patient's left
All four chambers side by side. This is the view for chamber comparison: the RV should be roughly 60% the size of the LV and the apex should belong to the LV.
Probe flat under the xiphoid, aimed up to the left shoulder · liver as the window
The view that works when the chest doesn't: COPD, mechanical ventilation, CPR pulse checks. The RV is the closest chamber to the probe — and the first place tamponade shows itself.
From subxiphoid, rotate sagittal · trace the IVC into the RA · measure ~2 cm from the junction
Size plus respiratory collapse gives you a rough CVP read: small and collapsing suggests an empty tank, fat and fixed suggests a full (or obstructed) one.
| Question | Where | Quick criteria |
|---|---|---|
| Squeeze? | PLAX, PSAX | Gestalt: hyperdynamic / normal / reduced / severely reduced. EPSS <7 mm supports normal EF; walls should visibly thicken |
| Effusion? | PLAX, subxiphoid | Anechoic stripe around the heart. Tamponade = effusion + RV diastolic collapse + plethoric IVC — a clinical + echo diagnosis |
| RV blown out? | A4C, PSAX | RV ≥ LV, D-sign, TAPSE <17 mm — full workup in No. 003 |
| Tank status? | IVC | Size + collapse as above; trend it, don't worship a single still |
| Valves grossly wrong? | PLAX, A4C + color | Flail leaflet, massive regurgitant jet, heavily calcified immobile AV. Subtle disease is formal echo's job |
A bad parasternal window is usually one rib space too high or too low, not insufficient pressure. Slide, don't press. Then try LLD.
In PLAX, pericardial effusion tracks anterior to the descending aorta; pleural effusion runs posterior to it. One gets a pericardiocentesis consult, the other a pigtail conversation.
An isolated anterior hypoechoic stripe that moves with the heart and contains speckles is usually fat, not effusion. True effusions are usually circumferential or dependent first.
In PLAX, if the mitral valve's anterior leaflet nearly slaps the septum each beat (E-point septal separation <7 mm), the EF is probably fine. Big gap, bad pump — caveats for MS and AI.
An A4C obtained one space too high slices the ventricle obliquely: fake small LV, fake big RV, fake wall motion. Find the true apex before trusting anything the view tells you.
Ten seconds, probe already in place before compressions pause, record the loop, resume. Review the clip while CPR continues — don't let the ultrasound stretch the pause.
