DOI: 10.1007/s10877-024-01251-1
Abstract: The capnodynamic method, End Expiratory Lung Volume CO2 (EELV-CO2), utilizes exhaled carbon dioxide analysis to estimate End-Expiratory Lung Volume (EELV) and has been validated in both normal lungs and lung injury models. Its performance under… read more here.

DOI: 10.1093/cvr/cvab326
Abstract: AIMS Hypoxic pulmonary vasoconstriction (HPV) is a physiological response to alveolar hypoxia that diverts blood flow from poorly ventilated to better aerated lung areas to optimize ventilation-perfusion matching. Yet, the exact sensory and signaling mechanisms… read more here.

DOI: 10.1093/cvr/cvx076
Abstract: Aims Hypoxic pulmonary vasoconstriction (HPV) redistributes blood flow from poorly ventilated to better aerated areas in the lung, thereby optimizing ventilation-perfusion ratio (V/Q). Pulmonary artery smooth muscle cell (PASMC) contraction in response to hypoxia is… read more here.

Hypoxic pulmonary vasoconstriction: Building a solid base
Sign Up to like & getrecommendations! Published in 2018 at "Experimental Physiology"
DOI: 10.1113/ep087179
Abstract: Hypoxic vasoconstriction is a response that is seen in the pulmonary circulation but not in any other vascular bed in the body. By diverting blood flow away from less well-ventilated regions in the lung, it… read more here.

DOI: 10.1152/japplphysiol.00509.2018
Abstract: RATIONALE Acetazolamide, a carbonic anhydrase inhibitor used for preventing altitude illness attenuates hypoxic pulmonary vasoconstriction (HPV) while improving oxygenation. Methazolamide, an analog of acetazolamide, is more lipophilic, has a longer half-life, and activates a major… read more here.

Sign Up to like & getrecommendations! Published in 2025 at "Physiology"
DOI: 10.1152/physiol.2025.40.s1.1269
Abstract: The pulmonary vasculature is under constant mechanical stimulation due to flow shear stress (many vascular bifurcations) and circumferential and longitudinal stretch (right ventricular stroke and respiration). Mechanic stimulation-induced vasodilation is thus important to help maintain… read more here.

DOI: 10.3389/fmed.2022.835481
Abstract: The pulmonary circulation responds to hypoxia with vasoconstriction, a mechanism that helps to adapt to short-lived hypoxic episodes. When sustained, hypoxic pulmonary vasoconstriction (HPV) may become deleterious, causing right ventricular hypertrophy and failure, and contributing… read more here.
