Hypoxic pulmonary vasoconstriction (HPV) is an important physiological phenomenon by which at alveolar hypoxia lung perfusion is matched to ventilation. The major vascular segment contributing to HPV is the intra-acinar artery. Here, we describe our protocol for the analysis of HPV of murine pulmonary vessels with diameters of 20-100 μm.

Blood pressure monitoring is one of the essential vital signs, and for a majority of patients, measuring it utilizing non-invasive techniques provides accurate values. However, there are situations in which the blood pressure requires more exact, specific, and reliable measurements.

This article describes a method for visualizing rat cerebral arteries through a cranial window using temporal craniectomy in order to view proximal portions of the middle cerebral artery (Figure 1). This versatile method can be combined with various techniques of drug delivery to measure cerebral artery reactivity in vivo.
FAQs
The measurement provides a quantitative basis for recognizing whether the lumen is smaller or larger than expected at a particular vascular location. Reduced diameter supports assessment of stenosis, whereas increased diameter contributes to evaluation of aneurysms. Comparing measurements between anatomical sites helps characterize abnormal vessel remodeling rather than relying only on visual impressions.
Arterial diameter may change during the cardiac cycle, so measurements taken at different phases can reveal dynamic behavior rather than a single static value. This comparison supports assessment of vascular function and blood-flow regulation. Recording the phase associated with each measurement also improves consistency when results are compared across examinations or study participants.
Standardization makes measurements more comparable by applying consistent approaches across patients, anatomical locations, time points, and research studies. Without this consistency, apparent changes could reflect differences in measurement conditions rather than true vascular change. Reliable comparisons are especially useful for tracking disease progression, evaluating treatment responses, and interpreting findings across studies.
The inner vessel boundaries establish the limits of the lumen, which is the region used for the diameter measurement. Accurate identification of these boundaries is therefore central to distinguishing the vessel space from surrounding tissue on an image. The resulting measurements can then be compared across locations or cardiac phases to evaluate structural and functional differences.
Ultrasound, computed tomography, and magnetic resonance scans can provide the images used for measurement. A general workflow selects the relevant vascular image, identifies the inner boundaries, records lumen width, and organizes the result by anatomical location or cardiac phase when available. Using a consistent workflow supports comparisons among examinations and patients.
The analysis is useful when evaluating vascular narrowing, aneurysms, abnormal remodeling, or changes in blood-flow regulation. It can also support assessment of how a vessel responds to treatment over time. In research, repeated and standardized measurements provide a way to compare vascular disease across patients, time points, and experimental studies.
