A post-op patient is receiving 50% oxygen via an air-entrainment nebulizer. The SpO2 has decreased to 90% and the minute ventilation is 13.9 L/min. Which of the following would increase the total flow to the patient to maintain an oxygen delivery of 50%?I. Bleed in 5 L/min to the air-entrainment nebulizerII. change to a dual flow nebulizer device with both air-entrainment nebulizers set at 50% with     15 L/min flowIII. Switch to a gas-injection nebulizer (GIN) with an oxygen flow rate set at 22 L/min and an       air flow meter set at 37 L/min

A patient is being weaned from mechanical ventilation by placing them on a Briggs T-adaptor trials. The physician orders for 15 minute trials each hour. The following were obtained prior to the first trial:HR: 80 bpmVC: 10 mL/kgFiO2: 0.40SpO2: 94%After breathing 10 minutes on the Briggs T-adaptor, the following are measured:HR: 100 bpmVC: 5 mL/kgFiO2: 0.40SpO2: 86%What should the respiratory therapist recommend?
