W monitored breathing pattern and arterial oxygen saturation in 32 conscious patients with acute ischemic stroke.Seventeen(53%)had Cheyne- Stokes respiration with concomitant drops in oxygen saturation,unrelated to infarct location.The ventilatory disturbance promptly reversed after intravenous theophylline ethylenediamine or oxygen inhalation.The therapy is a simple way of improving arterial oxygenation in a large subgroup of patients with acute ischemic stroke. |
