Vasodilation increases pulse pressure variation, mimicking hypovolemic status in rabbits
OBJECTIVE To test the hypothesis that pulse pressure respiratory variation (PPV) amplification, observed in hypovolemia, can also be observed during sodium nitroprusside (SNP)-induced vasodilation. INTRODUCTION PPV is largely used for early identification of cardiac responsiveness, especially when hypovolemia is suspected. PPV results from respiratory variation in transpulmonary blood flow an...
متن کاملPressure-induced vasodilation mimicking vasculopathy in a pediatric patient
PIV: pressure-induced vasodilation CASE REPORT A 9-year-old girl presented with a 1-day history of an asymptomatic, erythematous, blanching eruption on her bilateral posterior thighs and buttocks in the shape of lightning streaks and coinciding with the anatomy of the superficial gluteal arteries (Fig 1, A and B). The patient had no symptoms, and her mother incidentally observed the rash during...
متن کاملHydroxyamphetamine increases intraocular pressure in rabbits.
OBJECTIVE To determine the effect of norepinephrine (NE) released from endogenous ocular stores on intraocular pressure (IOP) and aqueous flow in rabbits. METHODS The IOP was measured with a pneumatonometer, the aqueous flow with a scanning fluorophotometer, and the aqueous NE by methylation with catechol-O-methyltransferase in the presence of S-adenosyl-L-[methyl-(3)H]methionine. RESULTS H...
متن کاملVentilator-induced pulse pressure variation in neonates.
During positive pressure ventilation, arterial pressure variations, like the pulse pressure variation (PPV), are observed in neonates. However, the frequency of the PPV does not always correspond with the respiratory rate. It is hypothesized that PPV is caused by cardiopulmonary interaction, but that this mismatch is related to the low respiratory rate/heart rate ratio. Therefore, the goal of t...
متن کاملVasodilation in Cholesterol-Fed Rabbits
Evidence exists that an endothelium-derived relaxing factor is nitric oxide and that L-arginine is the precursor for the synthesis of nitric oxide in vitro. Whether exogenous L-arginine contributes to the modulation of vascular smooth muscle tone in vivo is still controversial. In hypercholesterolemia, resistance vessels do not relax normally in response to pharmacological stimuli that release ...
