Condition: Used - Excellent
Type: Bi-level PAP
Model: VPAP II ST-A RESCONTROL
2 - Resmed Sullivan II ST - A. Comes with ResControl This units are in excellent condition and very low hours. The VPAP II ST-A provides a higher pressure during inhalation (IPAP) and a lower pressure during exhalation (EPAP). The VPAP II ST-A has three operating modes which determine how the changes between IPAP and EPAP pressures are made: Spontaneous, Spontaneous/Timed, and Timed. The VPAP II ST-A also has a CPAP mode in which a fixed pressure is delivered.
• In Spontaneous mode, the VPAP II ST-A senses when the patient breathes in and when the patient breathes out. The ventilator follows the patient’s spontaneous breathing rate to supply the appropriate pressure.
• In Spontaneous/Timed mode, the VPAP II ST-A will follow the patient’s spontaneous breathing (as in Spontaneous mode). However, the clinician also specifies a breathing rate (as in Timed mode) which they do not want the patient to fall below. This is a backup rate, which will be supplied if the patient’s spontaneous breathing rate becomes insufficient.
• In Timed mode, the clinician sets a breathing rate and an inspiratory time (as set by the IPAP Max parameter). This fixed rate is supplied to the patient at the fixed inspiratory time. AUTOMATIC LEAK MANAGEMENT
Vsync is the automatic leak management algorithm unique to the VPAP II Series. Vsync monitors and compensates for leak by continuously and automatically adjusting the baseline flow thereby maintaining reliable triggering and cycling.
For further details see “Vsync: Automatic Leak management – Trigger/Cycle Threshold Adjustment”The TiCONTROL feature which is also unique to the VPAP II Series, allows the clinician to set minimum and maximum limits on the time the ventilator spends in IPAP. The minimum and maximum time limits are set at either side of the patient’s ideal spontaneous inspiratory time, providing a “window of opportunity” for the patient to spontaneously cycle to EPAP.
The minimum time limit is set via the IPAP Min Time parameter and the maximum time limit is set via the IPAP Max Time parameter.
This section discusses the key parameters that need to be adjusted, and the
monitored items that are displayed in Spontaneous/Timed mode. The key adjustable parameters in this mode are: IPAP, EPAP, IPAP Max, Rise Time, BPM
ratio (this is a display-only item, but is dependent upon the IPAP Max and BPM settings) IPAP Min
The monitored parameters displayed in this mode are:, Respiratory Rate, Tidal Volume, Leak, Pressure The key adjustable parameters and monitored parameters.
