The first аrteriаl blооd gаs fоr an asthma patient in the emergency department reveals: pH 7.49; PaCO2 30; PaO2 82; SaO2 95%; HCO3- 24 on a nasal cannula 3 L/min. The patient’s peak expiratory flow rate was 165 L/min, respiratory rate was 16 breaths/min, and pulse 106 beats/min. After continuous aerosolized albuterol over the past hour, the patient’s current ABG results are as follows: pH 7.34; PaCO2 45; PaO2 49; SaO2 79%; HCO3- 25 on a high flow nasal cannula 15 L/min. The patient’s peak expiratory flow rate is 95 L/min, respiratory rate 35 breaths/min, pulse 128 beats/min, and the patient is diaphoretic. The respiratory therapist should suggest which of the following at this time? NPPV Intubation and mechanical ventilation Heliox Magnesium sulfate
