Echocardiography Quantification and Pulmonary Hypertension Scales

Flashcards covering Right Atrial Pressure (RAP) estimation based on IVC diameter and respiratory collapse, and Pulmonary Hypertension (PHTN) severity scales by RVSP and Acceleration Time.

Mild PHTN (by RVSP)

$$40-54\,mmHg$$

Moderate PHTN (by RVSP)

$$55-64\,mmHg$$

Severe PHTN (by RVSP)

$$\ge 65\,mmHg$$

Normal Acceleration Time

$$120-140\,ms$$

Borderline Acceleration Time

$$100\,ms$$

Usually PHTN (by Acceleration Time)

< 80\,ms

Severe PHTN (by Acceleration Time)

< 60\,ms
