The first аrteriаl blооd gаs fоr an asthma patient in the emergency department reveals: pH 7.49; partial pressure of carbon dioxide (PCO2) 30; partial pressure of oxygen (PO2) 82; oxygen saturation (SO2) 95%; bicarbonate (HCO3-) 24 on a nasal cannula 3 L/min. The patient’s peak expiratory flow rate was 165 L/min, respiratory rate was 16, and pulse 106. After continuous aerosolized albuterol over the last hour patient’scurrent arterial blood gas results are as follows: pH 7.34; PCO2 45; PO2 49; SO2 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, pulse 128, and the patient is diaphoretic. The respiratory therapist should suggest which of the following at this time? 2:4:4
