I-level positive airway pressure ventilation for patients with hypoxemia after coronary artery bypass grafting.

Coronary artery bypass grafting (CABG) is an effective scheme for treatment of myocardial ischemia. Hypoxemia is a common complication of CABG, which can affect surgical effect and prognosis and even induce multiple organ failure. To explore the clinical efficacy of bi-level positive airway pressure ventilation in the treatment of CABG-associated hypoxemia, 216 patients who were admitted to our hospital between August 2015 and April 2017 and developed CABG-associated hypoxemia were selected and randomly divided into 2 groups, an observation group (n=108) and a control group (n=108). Patients in the control group were given conventional treatment including continuous oxygen inhalation through nasal tube, anti-infection, bronchodilation, phlegm resolving, nutrition support, analgesia, cardiac function maintenance, coronary dilatation, anticoagulation and maintenance of stable internal environment, while patients in the observation group were given positive airway pressure ventilation via a breathing machine or nasal mask besides the conventional treatment.
