Abstract:
Objective To explore the influence of closed suction tube on end-tidal carbon dioxide partial pressure ( PET CO2 ) in infants with mechanical ventilation mass ≤10 kg.Methods The study investigated 78 infants with mechanical ventilation of nasal trachea cannula and the closed suction tube was used with constant respirator parameters .Since PET CO2 was continuously monitored for 2 hours before and after the use of closed suction tube , the vital signs and P ET CO2 were recorded at every 10 minutes.Results The body temperature, heart rate, breath, systolic pressure, diastolic pressure, and oxygen saturation remained stable before and after the use of closed suction tube .After 60 minutes of using closed suction tube , PET CO2 increased to (41.96 ±10.90)mmHg (t=-2.914,P<0.05).Conclusions PET CO2 is likely to increase after using closed suction tube for a long time in infants with mechanical ventilation mass ≤10 kg.
