Which of the following is true of pulse oximetry? 1. An emitter puts out a wavelength of light specific to deoxygenated hemoglobin which is detected by a sensor 2. An emitter puts out a wavelength of light specific to oxygenated hemoglobin which is detected by a sensor 3.  Variance in light is used to detect volume changes which is displayed as a pulse 4. The pressure of oxygen (PO2) is measured, and then displayed as a percentage

Assessment reveals: Chest radiograph reveals flattened diaphragm, hyperlucency with increase in intercostal space. Right cardiac silhouette is enlarged. ABG results on 2 lpm nasal cannula are pH 7.25, PaCO2 75  mmHg, PaO2 50 mmHg, HCO3 32 mEq/L. CBC: Hb 19 g/dl, Hct 57%, WBC 8,000 Lytes: Na 143, Cl 101, K 4.5, CO2 32 EKG: Sinus tachycardiaThe patient is still awake and alert and has a strong cough. What would you recommend now?Choose only ONE
