The older cell phones *could* affect some vents, IV pumps and monitors
it was found. But over the years technology has improved greatly and my
understanding is that banning cell phones is generally unneeded. I can
only think of one particular vent (HFOV) used infrequently at my
hospital that we still protect from cell phone transmissions. Patients,
family members, and medical staff use cell phones almost as much as land
lines anymore.
