What is the normal range for PA pressure in mmHg?

The correct answer reflects the typical pulmonary artery (PA) pressure range, which is essential for assessing cardiac and pulmonary health in patients, particularly those with conditions affecting heart function or pulmonary circulation.

Normal PA pressures are generally considered to be within the range of systolic pressures around 15-30 mmHg and diastolic pressures between 8-15 mmHg. This range helps to indicate that the right ventricle is effectively pumping blood into the pulmonary circulation and that there is adequate vascular resistance without significant pulmonary hypertension.

Systolic pressures above 30 mmHg or diastolic pressures over 15 mmHg might suggest the presence of pulmonary hypertension, which can have a profound impact on a patient’s overall cardiovascular health. Thus, recognizing and understanding the normal PA pressure range is vital for the monitoring and management of patients in acute care settings.

The other options provide values that fall either below or significantly above the accepted normal limits, indicating conditions that would necessitate further investigation or intervention. Adhering to these standards can guide clinical decisions and interventions for patients with cardiorespiratory issues.
