The number of elderly patients with essential hypertension is increasing annually at a rapid rate worldwide.
#PEEP MEDICAL ABBREVIATION REGISTRATION#
This trial was retrospectively registered, The Chinese trial registration number is ChiCTR-ROC-17012873. High levels of PEEP can significantly influence changes in blood pressure and heart function in elderly patients with hypertension. These results indicated that cardiac output significantly decreased. When PEEP was above 4 cm H 2O in the hypertension group, a decrease in blood pressure and ScvO 2, and an increase of heart rate were observed. In both groups, the increase in PEEP led to an increase in CVP and airway pressure. Changes in blood pressure, central venous pressure (CVP), central venous oxygen saturation (ScvO 2), heart rate, and airway pressure were determined in response to different selected PEEP levels of 0, 2, 4, 6, 8, 10 and 12 cm H 2O under SIMV(PC) + PSV mode throughout the study. Methodsįorty elderly patients above 65 years of age treated with mechanical ventilation were divided into two groups: a control group of non-hypertensive subjects ( n = 18) and a hypertension group ( n = 22) patients with essential hypertension. To study the effects of different positive end expiratory pressure (PEEP) on blood pressure and heart function in elderly patients with hypertension.
