Monitoring the patient's oxygen saturation is essential during the initial treatment of status asthmaticus. Arterial blood gas (ABG) values are usually used to assess hypercapnia during the patient's initial assessment. Oxygen saturation is then monitored via pulse oximetry throughout the treatment protocol. Oxygen saturation may increase following the use of bronchodilators secondary to an increase in V/Q mismatch.
