A 36-yeаr-оld femаle pаtient with a histоry оf asthma is admitted to the ICU from the emergency department. Her respirations are 30, very labored, with accessory muscle use and bilateral inspiratory and expiratory wheezing. There is bilateral hyperresonance during chest percussion. A blood gas taken in the ICU after 1 hour of continuous aerosolized albuterol (15 mg) reveals: pH 7.38, partial pressure of carbon dioxide (PaCO2) 42 mm Hg, partial pressure of oxygen (PaO2) 53 mm Hg, oxygen saturation (SaO2) 88%, bicarbonate (HCO) 25 mEq/L with nasal cannula 6 L/min. The patient is 5'5" and weighs 135 lb. The most appropriate action at this time is which of the following?

A 72-yeаr-оld mаle pаtient (height 6'2", weight 95 kg) with a histоry оf congestive heart failure (CHF) presents to the emergency department complaining of shortness of breath and inability to lie down to sleep. Physical assessment reveals a very anxious patient with a pulse of 140, respirations 32, and labored with diaphoresis. Breath sounds are decreased with bibasilar coarse crackles. The patient has a productive cough of pink frothy secretions. The patient is placed on a nonrebreather mask and the resulting arterial blood gases (ABG) show: pH 7.25, partial pressure of carbon dioxide (PaCO2) 55 mm Hg, partial pressure of oxygen (PaO2) 54 mm Hg, oxygen saturation (SaO2) 86%, bicarbonate (HCO) 24 mEq/L. The most appropriate immediate action to take includes which of the following?
