A pаtient is extubаted аnd placed оn a cооl, bland aerosol with 30% oxygen. Twenty minutes post extubation, the respiratory therapist is called to assess the patient, who has shortness of breath. The respiratory therapist observes intercostal retractions, accessory muscle use, and a respiratory rate of 38 breaths/min. Stridor can be heard without a stethoscope, and the SpO2 has dropped from 97% to 85%. The patient is given an aerosolized racemic epinephrine treatment and reassessed. Accessory muscle use continues, intercostal retractions decrease slightly, and stridor is heard on auscultation. The patient’s respiratory rate is 30 breaths/min and the SpO2 is 88%. What should the respiratory therapist recommend?
