Glossary<br />
Rtot<br />
Parameter measured by the ventilator equal to the total number of breaths per minute (bpm).<br />
Sensitivity<br />
This adjustable parameter determines the amount of inspiratory effort required by the patient<br />
before the ventilator delivers an assisted breath, or demands flow in the case of a spontaneous<br />
breath.<br />
The <strong>Puritan</strong> <strong>Bennett</strong> <strong>560</strong> <strong>Ventilator</strong> is flow-triggered, with sensitivity levels in the range from<br />
1 to 5: the lower the number, the more sensitive the trigger.<br />
Sigh<br />
A sigh is an increased volume of gas delivered to the patient at a set rate. i.e. every 50 breaths.<br />
Spont Cyc (Spontaneous Cycling)<br />
This is the percentage of ventilation cycles initiated by the patient over the previous 24 hour period.<br />
Spontaneous<br />
A ventilation mode that delivers assisted breaths only. Spontaneous mode does not provide breaths<br />
if the patient does not make an inspiratory effort greater than the sensitivity settings and there is<br />
no apnea backup rate.<br />
Standby<br />
The operational mode of the ventilator where it is powered (power supply I/O button set to the<br />
I position), but is not ventilating the patient.<br />
SIMV (Synchronised Intermittent Mandatory Ventilation)<br />
A ventilator mode which provides a mechanism for synchronising the ventilator-delivered breaths<br />
with a patient's inspiration, as detected by the ventilator.<br />
Tidal volume (Vt)<br />
Volume of gas delivered to the patient in a breath.<br />
Unfreeze<br />
Resumption of the waveform plot tracing on the ventilator’s display.<br />
V A/C (Volume Assist / Control)<br />
A ventilator mode which provides machine-initiated breaths are delivered at a clinician-set volume<br />
inspiratory time, and rate.<br />
Vent Time (Ventilation Time)<br />
The ventilation duration data is based on the patient counter and shows the total ventilation time<br />
in hours and minutes over the previous 24 hour period.<br />
Volume breath<br />
Inspiration of the selected volume, delivered over the selected inspiratory time.<br />
