Cardiovascular effects of inhaled oxygen assessed with magnetic resonance imaging
Introduction International practice guidelines prescribe the administration of 10–15 liters/min of O2 to all critically ill patients, including to those who are initially normoxic. However, there are observations to suggest that inhaled supplemental O2 may increase blood pressure and decrease cardiac output (CO) and coronary blood flow (CBF). The aim of this study was to establish the acute car...
متن کاملCardiovascular and hypokalaemic effects of inhaled salbutamol, fenoterol, and isoprenaline.
The cardiovascular and hypokalaemic effects of equal doses of inhaled fenoterol, isoprenaline and salbutamol were compared in eight healthy male volunteers, in a double blind, placebo controlled study. Increasing doses of 400, 600, and 800 micrograms were given from a metered dose inhaler at 15 minute intervals, followed by measurements of heart rate, blood pressure, total electromechanical sys...
متن کاملProtective effects of inhaled ipratropium bromide on bronchoconstriction induced by adenosine and methacholine in asthma.
Although adenosine-induced bronchoconstriction is mainly due to mast cell mediator release, vagal reflexes have also been implicated in this response. We have investigated the effect of a specific muscarinic-receptor antagonist, ipratropium bromide, on methacholine- and adenosine-induced bronchoconstriction in a randomized, placebo-controlled, double-blind study of 12 asthmatic subjects. Airway...
متن کاملCardiovascular Effects of Acute Organophosphate Poisoning
Background:Cardiovascular effects of acute organophosphate (OP) poisoning are common. This study was aimed to assess the cardiovascular effects of OP poisoned patients in Nepal. Methods:This was a prospective hospital-based cross-sectional study of 115 acute OP poisoned patients presenting in emergency department of a tertiary care teaching hospital of central Nepal during November 2008 to Octo...
متن کاملCardiovascular effects of inhaled nitric oxide in a canine model of cardiomyopathy.
BACKGROUND The inhalation of nitric oxide (NO) in patients with heart failure decreases pulmonary vascular resistance (PVR) and is associated with an increase in pulmonary artery wedge pressure (PAWP). The mechanism for this effect remains unclear. METHODS In dogs rapid-paced for 8 weeks to induce cardiac dysfunction, we performed left ventricular pressure-volume analysis of unpaced hearts in...
