The Effect Of Endotracheal Suction In Critical Patients

Endotracheal suction is an important nursing method to critical patientswho receive endotracheal tube (ETT) ortracheostomy tube (TT)。Most of the critical patients need endotracheal suction,however, endotracheal suction is a process, which can take some negativeeffects even injury to them. Recently researchers have done some works aboutthe effects of endotracheal suction on some critical patients. This report aims tofind the effects of endotracheal suction on critical patients through 30 patients.It is well known that endotracheal suction can result in changing of heartrate, blood pressure and oxygenation saturation. Different suctionpressure(0.01MPa,0.015Mp,0.02MPa) and suction time(5-10s,10-15s,15-20s) have relations with the change of heart rate, blood pressure, oxygensaturation and mucus bleeding during endotracheal suction through 30 criticalpatients.All the data in this research are done by statistic. The sputum of ETTpatients is denser than that of TT patients (P<0.05), which means that the ETTpatients'airway need more humid. When the suction press is 0.01Mpa,the rateof mucus bleeding is 2.94%, and when the suction press is 0.015Mpa, the rate ofmucus bleeding is 6.38%, and when the suction press is 0.02Mpa, the rate ofmucus bleeding is 14.52%, it means that higher suction press can lead to morerate of mucus bleeding(P<0.05),so the suction press must be controlled under0.02Mpa.The rate, average blood press and oxygenation saturation varies withdifferent suction press .They have positive relation, for example, F valuebetween heart rate and suction press is 6.3, F value between oxygenation...
