Test the operation of the VDR®-4 patient disconnect alarm when
doing pre-use check and pre-setup procedure. An increase in
circuit resistance can prevent proper operations of some alarms.
Speaking valves, heat moisture exchangers (HMEs), and filters
create additional circuit resistance and may affect the performance
of alarms chosen for circuit disconnect protection.
Prior to placing a patient on the VDR®-4 ventilator, a clinical
assessment should be completed to determine the device alarm
settings, alternative ventilation equipment needed, and if an
alternative monitor is required.
Therapists should evaluate how their patients tolerate mechanical
ventilation with the VDR®-4. Auscultation and observation of
the chest and abdomen can be primary indicators of effective
mechanical ventilation.
The VDR®-4 is a restricted medical device designed for hospital
use by respiratory therapists or other trained clinicians under the
supervision of a physician.
The operator of the VDR®-4 is responsible for reading and
understanding the manual before use.
All persons using the VDR®-4 ventilation device must be trained in
its use.
Pre-use checks must be completed before any ventilation is
started on a new patient. If any abnormal function is noted,
do not start ventilation.
Failure to comply could cause injury or death to the patient.
Alarm functions must be tested prior to each use to verify the
capability of the device to detect conditions that could cause
injury to the patient.
Proper care needs to be taken during setup to ensure all
lines running to or from the patient circuit are not crimped or
perforated. Failure to conform could cause malfunction of alarms
and/or pressure limit controls.
Proper support and orientation of the patient circuit must be made
to avoid inadvertent disconnection.
Water traps (if used) should be drained at intervals to prevent the
possibility of injury to the patient.
All guidelines in this manual are only suggested; always follow
hospital or institutional protocols.
