  1. 1. Hypoxic pulmonary vasoconstriction and nitric oxide

    Author : Kristina Hambraeus Jonzon; Karolinska Institutet; Karolinska Institutet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; hypoxia; pulmonary vasoconstriction; regional pulmonary bloodflow; stimulus-response; nitric oxide; blood-borne distant effects; nitric oxide synthase activity; inhaled; exhaled; non-enzymatic;

    Abstract : Hypoxia causes pulmonary vasoconstriction (HPV), improving oxygenation by redistribution of the pulmonary blood flow to better oxygenated lung regions. HPV is intrinsic to the pulmonary vascular smooth muscle cell, but can be modulated by several vasoactive substances, as for example endothelium derived nitric oxide (NO) and endothelin-1 (ET-1).

  2. 2. Endogenous Nitric Oxide Production and Pulmonary Blood Flow : during different experimental lung conditions

    Author : Manja Nilsson; Filip Fredén; Kristina Hambraeus-Jonzon; Göran Hedenstierna; Eddie Weitzberg; Uppsala universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Nitric oxide; pulmonary blood flow; endotoxin; nitric oxide inhalation; endothelin; hypercapnia; acidosis; lavage-induced lung injury; Anaesthetics and intensive care; Anestesiologi och intensivvård; Anestesiologi och intensivvård; Anaesthesiology and Intensive Care;

    Abstract : Nitric oxide (NO) is an important regulator of pulmonary blood flow and attenuates hypoxic pulmonary vasoconstriction (HPV). Nitric oxide is synthesized enzymatically in a number of tissues, including the lungs, and can also be generated from reduction of nitrite during hypoxia and acidosis. READ MORE
