The MOVES® SLC™ is a portable ventilator which is computer-controlled and electrically powered. It is intended to provide continuous or intermittent ventilatory support for the care of individuals who require mechanical ventilation. The MOVES® SLC™ can also supply supplementary O2 to spontaneously breathing patients, which will be further described in the following section.
Intubated patients are ventilated with a circle circuit (called a ventilator circuit) used with a ventilator cartridge. Oxygen and air enter the circuit from either the oxygen concentrator, the air pump or an external O2 supply. The oxygen concentrator can be set to provide an intubated patient with an inspired O2 concentration (FiO2) between 30% and 85%. In Ventilator mode, the air pump serves as a back-up source of air flow if the system concentration of oxygen is too low or carbon dioxide is too high or either is unknown.
The ventilator is comprised of a blower, a sealed ventilator chamber that houses the ventilator bag (air / oxygen reservoir), and a valve block that interfaces with the breathing cartridge and ventilator breathing circuit. The valve block includes the following components:
During patient inhalation, the blower pressurizes the ventilator chamber which displaces the gas from the ventilator bag into the patient’s breathing circuit. The blower draws external air through an inlet filter. During exhalation, the patient’s expired gas is directed to the ventilator bag. The ventilator bag also receives oxygen from the concentrator or external O2 source and air from the air pump.
The Ventilator and Vent Mode specifications are located at pages 310-314 of the Operator Manual. The MOVES® SLC™ can be used to do pressure and volume control ventilation in a number of different ventilator modes:
There are three user-serviceable components in the MOVES® SLC™ system:
The hydrocarbon filter should be replaced when the system alarm indicates it is occluded. The ventilator filter should be replaced every six (6) months. The ventilator CO2 scrubber liner should be replaced every three (3) months.
It is important that before installing a hydrocarbon filter, that the user check the four-digit date code printed on the cartridge. The cartridge label is stamped “XXYY”, where XX is the week of the year and YY is the year of manufacture. A cartridge of more than three years old should not be used and may degrade the performance of or cause damage to the Oxygen Concentrator.
1. Always install a hydrocarbon filter before powering up MOVES® SLC™. The MOVES® SLC™ will alert you with an alarm if it becomes clogged.
2. Insert the hydrocarbon filter as shown into the REAR panel of the MOVES® SLC™ unit.
3. Rotate the hydrocarbon filter clockwise to install, counterclockwise to remove.
1. Locate the Ventilator Filter Cover on the MOVES® SLC™.
2. Unscrew the Cover Thumb Screw.
3.Lift the Ventilator Filter Cover and locate the filter.
4. Press the filter frame down while turning counterclockwise.
5. Remove the filter.
6. Once the old Ventilator Filter has been removed, it should be discarded in accordance with local regulations.
7. Install a new filter by following the previous steps in reverse order.
Note: If the filter is not properly seated the lid will not close. Do not force it. Unscrew the filter and then re-seat it.
1. Open the CO2 Scrubber door and locate the liner.
Note: The CO2 Scrubber should never be left inside after the unit is used. If present, remove and discard the CO2 Scrubber.
2. Fold and hold the Liner with two hands at the Liner edge
3.Pull the liner forward until it is fully removed from the cavity.
4. Discard the old Liner
5. Clean the CO2 Scrubber Chamber and door with a wet cloth and mild detergent if needed. Do not allow any cleaning product to reach any chamber opening.
6. Place the new Liner on the middle tube. Pay attention to the orientation of the Liner. The Liner’s water collecting cavity should be at the bottom.
7. Slowly push the liner forward until its bottom reaches the back wall of the CO2 Scrubber cavity.
8. Ensure the Liner is fully seated:
9. The bottom water collecting cavity is fully seated in the corresponding recess.
10. Rotate the liner about the middle tube until the inspiratory hole matches the corresponding liner hole.
