Abstract
Aim The aim of this study was to evaluate the effect of planned breathing exercises on oxygenation in patients undergoing coronary artery bypass surgery.Background Pulmonary complications and impaired oxygenation are common after coronary artery bypass graft surgery and cause increased hospitalization and health care costs. Breathing exercises are applied commonly in managing coronary artery bypass graft (CABG) patients in many hospitals, but scientific evidence is not sufficient about the efficacy of this treatment.Method In a clinical trial , 100 patients undergoing CABG were randomly allocated to planned breathing exercises (n=50) and control group (n=50). The patients in experimental group received breathing exercises protocol (deep breathing, incentive spirometry and directed cough maneuvers) and the patients in control group received daily routine hospital physiotherapy. Other therapies were similar in two groups. Arterial blood gases were compared between groups before operation and the first, second and third postoperative day. The data were analyzed by SPSS Version 17 software using chi square, T test and analysis of variance.Findings The study findings showed no statistically significant difference between groups in terms of demographic data, history of chronic diseases, Pao2 and Sao2 before surgery and on the first and second day after surgery. On the third postoperative day, the mean score of SaO2 (95, SD=2.47 vs. 93.24, SD=16.3, p=0.003) and PaO2 (83.19, SD=16.23 vs. 72.66, SD=13.20, P≤0.001) were higher in the experimental group.Conclusion The patients receiving planned breathing exercises including deep-breathing exercises, incentive spirometry and directed cough maneuvers have better oxygenation after coronary artery bypass surgery.

Abstract
Aim. This literature review investigates the role of ECMO in the management of pulmonary barotrauma in people with decompression sickness (DCS).
Background. As a result of change in the atmospheric pressure in sea depth, divers may experience life threatening conditions such as barotrauma in vital organs including the lungs. Delivering 100% oxygen is the immediate treatment in these situations. A modern technology for oxygen therapy and supporting vital organs in heart and lung failure is extracorporeal membrane oxygenation (ECMO).
Method. This review was conducted by searching out databases UpToDate, Google scholar, Elsevier, SID and Magiran between 1995-2016 by the following keywords: diver, diving, decompression sickness, decompression syndrome, lung injuries, respiratory disorders, pulmonary barotrauma, treatment, and ECMO, and their Persian equivalents.
Findings. Oxygen administration and prevention of severe complications caused by accumulation of nitrogen bubbles in the body is an important treatment in this DCS. Oxygenation by nasal cannula in early stage and hyperbaric oxygenation in sever conditions are common treatments. ECMO can remove nitrogen bubbles of the blood and body and decrease concentration of nitrogen in the blood, and furthermore, improves oxygenation.
Conclusion. To rescue and prevent death in DCS victims, it is required to consider appropriate measures by minimum side effects. To do so, veno-venous ECMO can be a safe technique. The studies conducted in this field are limited; therefore more studies about ECMO usage in DCS must be conducted.

Abstract
Aim. This paper aims to review the effect of Extracorporeal Membrane Oxygenation (ECMO) method on treatment of drug poisoning caused by calcium blockers and beta-blockers.
Background. A large proportion of cardiovascular drug poisoning is associated with calcium channel blockers and beta-blockers. Among the various and severe symptoms of poisoning with these drugs, treatment of resistant shock or acute respiratory distress is considered as a challenge. Extracorporeal membrane oxygenation can be used as one of the effective therapies for this type of poisoning.
Method. This study is a literature review that was conducted through searching out databases Web of Science, Scopus and PubMed with keywords "Extracorporeal membrane oxygenation", "ECMO", "Calcium channel blocker" and "Beta blocker" in the title, abstract, and keywords of the articles. The articles with focus on the effects of ECMO on treatment of poisoning caused by calcium blocker and beta-blocker drugs were selected and reviewed.
Findings. Twenty articles were included, in which 23 patients with beta-blocker or calcium blocker poisoning were reported to be treated with ECMO as an adjunct device. VA-ECMO and VV-ECMO were used in 22 and one of cases, respectively. In general, the use of ECMO has been completely successful in more than 90 percent of those patients who suffered from cardiovascular drug poisoning.
Conclusion. In view of the newness of ECMO and the lack of clinical trials in this subject, the results of reported case studies indicate a high success rate of this method in treatment of calcium and beta-blockers poisoning. It is recommended this treatment to be considered by healthcare team to treat beta-blocker or calcium blocker poisoning.
