Hypoxia algorithm is shown. Note: Routine pulse oximetry only for patients with DepoDur [Pacira, Parsippany, NJ, USA] and when clinically indicated (ie, patients with morbid obesity, sleep apnea, respiratory disease, or patients who require high doses of opioids). RR = respiratory rate; HR = heart rate; Pox = percentage oxygen saturation; EKG = echocardiogram; CXR = chest xray; CBC = complete blood count; BMP = basic metabolic panel; PE = pulmonary embolism; NC = nasal cannula; ABG = arterial blood gas; A-a = alveolar-arterial; MDCT = multidetector computed tomography scan; V/Q = ventilation/perfusion scan.
