What is the systolic pressure in pulmonary artery pressure measurements?

The correct answer is based on the established norms for pulmonary artery pressure, which is essential for assessing the hemodynamics of the heart and lungs. Systolic pulmonary artery pressure typically ranges from 15 to 30 mmHg in a healthy adult. This range indicates the pressure within the pulmonary artery during the contraction of the right ventricle when blood is ejected into the pulmonary circulation.

Understanding this range is crucial for clinicians, as elevated or decreased pressures can indicate various cardiac or pulmonary conditions. For example, values significantly above this range could suggest pulmonary hypertension, while values below might not provide adequate perfusion and could indicate right heart failure or other issues.

The other ranges presented do not align with typical physiological values for systolic pulmonary artery pressure, making them less accurate in a clinical context. Knowing the normal pressure ranges helps health care professionals interpret pulmonary artery pressure measurements accurately and intervene appropriately in critical care settings.
