Emergency Assessment of Unresponsive Patient

A 67-year-old male patient arrives at the emergency department after being found unresponsive at home. The initial assessment reveals a weak pulse, slow respirations, and a significant drop in blood pressure. Upon examination, an advanced directive indicates the patient has a history of chronic obstructive pulmonary disease (COPD) and takes bronchodilators regularly. A rapid assessment shows that his blood pressure reads ___ mm Hg, respiratory rate is ___ breaths per minute and his oxygen saturation is critically low at ___%. Based on this information, consider the most appropriate pre-hospital intervention, which includes securing the airway and preparing for potential intubation if his respiratory status does not improve.
