Abstract

We studied changes in organism’s sensitivity and resistance to hypoxic hypoxia under conditions of NMDA receptor blockade with MK-801. Breathing hypoxic gas mixture after administration of MK-801 sharply decreased the mean blood pressure in the systemic circulation and slightly improved lung ventilation in animals. Respiratory arrest was observed in 40% animals. NMDA receptor blockade decreased organism’s sensitivity and resistance to hypoxic hypoxia.
