Which of the following values represents the diastolic pressure in pulmonary artery pressure?

Diastolic pulmonary artery pressure (dPAP) is an important hemodynamic measurement used to assess the pressure within the pulmonary artery during diastole, which is the phase of the heart cycle when the heart muscle relaxes and the chambers fill with blood. The normal range for diastolic pulmonary artery pressure typically falls between 5 and 15 mmHg.

This range is significant clinically because it helps in the evaluation of pulmonary vascular resistance and the overall function of the right side of the heart. If the dPAP is elevated beyond this range, it may indicate conditions such as pulmonary hypertension or left heart failure, which can lead to increased pressures within the pulmonary circulatory system.

Choosing the range of 5-15 mmHg as the correct value accurately reflects the accepted standards in critical care settings, aligning with guidelines and literature on pulmonary artery pressure measurements. Understanding these values is crucial for monitoring patients with respiratory and cardiac conditions effectively, ensuring appropriate interventions can be applied based on the pressure readings.
