A 30-year old female was anaesthetically induced for an elective open cholecystectomy. Upon mask ventilation, patient’s oxygen saturation level dropped to 90% despite maximal head extension, jaw thrust and two handed mask seal. Intubation was performed twice but failed. Use of bougie also failed to localize the trachea. Oxygen levels continued to drop, but was maintained between 80 and 88% with mask ventilation. Which of the following options is the best action to take for this patient?

Taking into consideration the values above, in which of the following ranges will his osmolarity fall into?
