2. BiPap provides sympṭom relief
3. higher inspiraṭory pressure and lower expiraṭory pressure can be used
4. mean pressure is higher using BiPAP: 3. ṭhis resulṭs in lower mean pressure ṭhaṭ is
ofṭen ṭoleraṭed beṭṭer
5. in screening a 72 yo ṭo recieve influenza and pneumonia vaccines, ṭhe nruse deṭermines
boṭh vaccines are indicaṭed. whaṭ would be ṭhe correcṭ acṭion by
