The purpose of this study is to assess if arm elevation, with or without simultaneous deep breathing, affects oxygen saturation and lung function on patients two to four days after open heart surgery.
This single center, interventional crossover study will involve patients day 2, 3 or 4 after open heart surgery. Patients who meet the eligibility requirements will be informed about the study and potential risks, given a written informed consent they will be included for intervention being held later on the same day. Randomization will be given to the investigator in a sealed envelope and being opened after base line measurements. Data will then be collected for the randomized intervention and after a wash out period (several minutes) again for the crossover intervention.
