The cardiovascular, pulmonary, and ocular hypotensive effects of 0.2% brimonidine.

Objective: To compare the cardiovascular, pulmonary, and ocular hypotensive effects of 0.2% brimonidine tartrate with those of 0.5% timolol maleate, 0.

Cardiovascular and intraocular pressure effects and plasma concentrations of apraclonidine.

We performed a double-masked, crossover study comparing the cardiovascular and intraocular pressure effects of 0.5% and 0.25% topical apraclonidine hydrochloride and 0.

Simultaneous chest compression and ventilation at high airway pressure during cardiopulmonary resuscitation.

In most patients blood flow during cardiopulmonary resuscitation (CPR) results from a rise in intrathoracic pressure rather than from direct heart compression. Intrathoracic pressure was increased by the use of positive-pressure ventilation synchronous with sternal compression in eleven arrested patients who were intubated. A computer system allowed 15-30 s periods of alternation between conventional CPR and "new CPR" (rate of 40/min, 60% compression duration, and simultaneous ventilation at airway pressures from 60 to 110 cm H2O).
