This survey was performed to compare two hypoxemic intratracheal suctioning methods on the hemodynamic condition of 30 patients who were undergoing open heart surgery and mechanical ventilation in control mode. Hemodynamic parameters included systolic and diastolic pressures, heart rate, and cardiac rhythm measured in four phases and then recorded. The results showed that both systolic and diastolic pressures and also heart rate changes in various phases of both methods respectively with no statistically significant difference. The rhythm changes was toward sinus tachycardia (P < 0.001). Also the comparsion of both methods in four phases (control phase) showed diastolic pressure changes in hyperoxygenation to be higher than hyperinflation (P <0.05). However, systolic pressure changes were not statistically significant. The comparison of heart rate changes in the second phase of hyperinflation method was increased more than that in the other method (P<0.05). Rhythm changes was more or less of the hazardous type rhythms (P<0.01).
