Flashcards: Pulmonary Hemodynamics and Ventilation Management — 18 cards

Pulmonary Arterial Pressure — definition?

Pressure in pulmonary artery reflecting blood flow.

Normal PAP range (right heart)?

10-20 mm Hg.

Normal PAP range (left heart)?

8-12 mm Hg.

High PAP — cause?

Overload or pulmonary hypertension.

Low PAP — cause?

Dehydration or low volume.

Cardiogenic shock — effect on PAP?

Decreases due to impaired cardiac output.

Mitral stenosis — effect on PAP?

Increases due to pulmonary venous hypertension.

Cardiac Output — range?

4-8 L/min.

Systemic Vascular Resistance — range?

900-1400 dyn·s/cm5.

PAP measurement method?

Invasive via right heart catheterization.

Hemodynamic ranges — PPOP?

8-12 mm Hg.

Hemodynamic ranges — CO?

4-8 L/min.

Hemodynamic ranges — SVR?

900-1400 dyn·s/cm5.

Mechanical ventilation — key parameter?

Tidal volume, FiO2, PEEP.

Ventilation — hypoxia management?

Increase FiO2 and PEEP.

Vasopressors — role?

Increase SVR in vasodilation.

High vs low PAP — significance?

Indicates overload or volume depletion.

PAP origin — importance?

Differentiates left vs right heart influences.
