[A comparative study of the effects of control ventilation and synchronized intermittent mandatory ventilation on hemodynamic and blood gases in patients with chronic obstructive pulmonary disease].
Effects of control ventilation (CV) and synchronized intermittent mandatory ventilation (SIMV) were comparatively studied in 9 patients with chronic obstructive pulmonary disease. Cardiac index (from 2.99 +/- 0.65 to 3.60 +/- 0.651.min-1.m-2, P < 0.05) and oxygen delivery index (from 537 +/- 89 to 645 +/- 101 ml.min-1.m-2, P < 0.05) were significantly increased during SIMV comparing with CV. Mixed venous oxygen tension (from 5.63 +/- 0.66 to 6.06 +/- 0.59 kPa, P < 0.01) was improved by SIMV. The results showed that SIMV could improve cardiac output, oxygen delivery and oxygen supply of tissue.
