2.5 Intended use and performance
The intended use of VitaGuard® is to detect central apneas when the
patient is completely immobile on a stable underground and to moni-
tor the heart. VitaGuard® is designed for applications at home and in
rooms used for medical purposes. VitaGuard® has no therapeutic effect.
VitaGuard® emits an acoustic and visual alarm when no respiration or
movement is detected within a set period, when the measured heart
rate values violate the set alarm limits for a period also set by the
operator, and/or when no heartbeat has been detected for a set
period. The alarm limits can be set within particular values specified
by VitaGuard®.
Respiration and heart rate are monitored with adhesive ECG elec-
trodes. VitaGuard® determines the heart rate from the ECG signal
detected by the electrodes.
VitaGuard® features an impedance monitor that triggers a technical
alarm when an electrode exhibits impedance values that are not
compatible with proper operation. This is the case, for example, when
an electrode has become detached.
Physiological data measured for a set period before and after an
alarm are stored and can afterwards be evaluated and documented.
VitaGuard® can be operated with the NA3000-2 power adapter (9 V),
the NAK3000-2 automobile power adapter (e.g. in the cigarette
lighter), four non-rechargeable batteries, or a rechargeable block
battery. Non-rechargeable batteries or the rechargeable block battery
serve above all to safeguard the monitor’s functions during a power
failure and to continue monitoring when patients are in transit.
