I also carry vaseline gauze or a commercial chest seal. Takes up little room. A chest injury that would require this might be a lost cause but will go all out to save a family member. Also, Lactated Ringers is very hard to come by without a prescription ( as are many meds on the list). Normal Saline can be purchased on-line without an RX. LMA’s are great but are bulky. A laryngoscope w 2 blades, batteries, tubes, etc are just as bad. Learning how to use the nasal trumpets and a compact ambu bag would be great.
Training, training, training….
