Effect of sodium nitroprusside-induced hypotension on pulmonary deadspace.
Deliberate hypotension with nitroprusside produced a 40% reduction in mean arterial pressure, but it did not cause any change in the pulmonary deadspace to tidal volume ratio ( Vb/ Vr). This was achieved by adequate hydration both before and during hypotension, as indicated by constant filling pressures. Thus we have shown that deliberate hypotension per se does not increase Vb/ VT, and that va...
متن کاملCardiovascular Effect of Dorsal Periaqueductal Gray During Lipopolysaccharide-induced Hypotension
Introduction: The central mechanism related to the cardiovascular response to lipopolysaccharide (LPS)-induced hypotension is not entirely known, but it is suggested that numerous brain areas such as dorsal periaqueductal gray (dPAG) are involved in this process. In the current work, the cardiovascular effect of the dPAG during LPS-induced hypotension is investigated. Methods: The study animal...
متن کاملPulmonary Gas Exchange during Deliberate Hypotension.
Respiratory physiological deadspace may increase from 35 per cent of the tidal volume in the normal anaesthetized, normotensive and supine patient to as much as 80 per cent in the hypotensive patient in the head-up tilt. Increased mean airway pressure, hypotension, sudden head-up tilt or maintenance of tilt, all tend to increase the respiratory deadspace. Arterial and end-tidal Pco3 differences...
متن کاملHyperventilation-induced hypotension during cardiopulmonary resuscitation.
BACKGROUND A clinical observational study revealed that rescuers consistently hyperventilated patients during out-of-hospital cardiopulmonary resuscitation (CPR). The objective of this study was to quantify the degree of excessive ventilation in humans and determine if comparable excessive ventilation rates during CPR in animals significantly decrease coronary perfusion pressure and survival. ...
متن کاملFluoxetine Induced Hypotension; a Rare Report
Fluoxetine is a selective serotonin reuptake inhibitor (SSRI) that exerts its anti-depressive effect by blocking the presynaptic reuptake of the neurotransmitter serotonin (5-HT). Although fluoxetine is usually considered safe for most patients, in the present case report, we describe a young patient with mixed anxiety and depression disorder (MADD) treated with fluoxetine 10 mg/day, who develo...
