Question: hello, in regards to COVID 19, are paramedics using surgical masks or N-95 when applying Flo2max? will it depend if our patient is screened negative or positive or pending? I understand in AGMP’s we are to use N-95. it is my understanding that Flo2max is a high concentration/ low flow mask system. a second question, would you advise to proceed with applying flo2max rather than NRB masks on all patients who are FREI positive and/or Covid 19 screened positive?
