The effect of Automatic Tube Compensation on internal PEEP in Chronic Obstructive Pulmonary Disease in Intensive Care Unit. 2020-05-20 anticipated 60 Complete https://irct.ir/trial/48029 interventional Randomization: Not randomized, Blinding: Not blinded, Placebo: Not used, Assignment: Parallel, Purpose: Treatment. N/A COPD. Intervention 1: Intervention group: This study is a clinical trial that is performed randomly using available samples and the effect of ATC on the internal PEEP rate of COPD patients in the ICU will be investigated. In the first group, before activating the ATC mode, the patient's airway is suctioned so that the airway pressure does not change due to secretions, then once every 6 seconds for 1 minute the initial internal PEEP value is recorded and its average is listed in the checklist. To do this study, we use the Hamilton c2 ventilator. Intervention 2: Intervention group: This study is a clinical trial that is performed randomly using available samples and the effect of ATC on the internal PEEP rate of COPD patients in the ICU will be investigated. In the second group, the ATC mode is activated, and one minute after the start of the ATC mode, the internal PEEP is recorded every 6 seconds for one minute and its average is taken. This process is repeated 6 minutes later until the average internal PEEP is recorded 6 times after ATC activation.To do this study, we use the Hamilton c2 ventilator.
