1. MACS CPAP System
Self Guided Tour

2. Program Objectives This program is a self guided tour of the
MACS CPAP System.
At the end of this tour you will be able to:
Describe the main operating features of MACS
Identify the controls and connections
Describe the patient breathing circuit
Set-up MACS for patient operation
Define various clinical environments for CPAP application
Clean and maintain the MACS

3. Features and Controls – Rear Panel
Driving Gas Input
Connection for 55 psi (3.8 bar) oxygen source gas
Always use a high flow gas source (pressure take-off) that can provide psi pressure at a minimum of 40 L/min

4. Features and Controls – Rear Panel
Air Entrainment
Ambient air is entrained for internal gas mixing
External housing contains air filter
Air filter replacement is part of the preventative maintenance

5. Features and Controls – Front Panel
CPAP Control
Adjusts the CPAP from 0 to 20 cm H2O
Automatic sensitivity
Flow adjusts automatically to meet patient demand up to 140 L/min
Oxygen concentration is maintained at set % Oxygen control

6. Features and Controls – Front Panel
% Oxygen Control
Delivered oxygen choice
65%
100%
Sets the spontaneous breath oxygen concentration

7. Features and Controls – Front Panel
Pressure Gauge
Shows pressure in patient circuit at the output of MACS
Compare with control setting to insure proper operation
Gives an indication of patient effort

8. Features and Controls – Front Panel
Circuit Connection 1
Connection for the large bore hose of the patient circuit

9. Features and Controls – Front Panel
Circuit Connection 2
Patient circuit small hose connection
Connects to the expiratory valve on the patient circuit

10. Patient Breathing Circuit
Patient circuit is a single limb system
Both hoses attach to the front of MACS
Patient end connects for clinical intervention
Directly to an endotracheal tube (invasive)
Face mask (noninvasive)

11. Patient Breathing Circuit
Use only Airon Corporation patient circuits
Calibration of the CPAP control is based upon the Airon patient circuit
Using other manufacturers circuits may cause
errors in pressure delivery
high expiratory flow resistance
interference with CPAP sensitivity
increased oxygen usage

12. Patient Breathing Circuit
Accessories to optimize patient care
In-line medication nebulizer
Fits between the mask and patient circuit
Nebulizer can be removed to add medication while maintaining pressure
CO2 monitoring
For In-line sampling place the Tee between the mask and circuit
Or use the nasal prongs under the mask
Expiratory bacteria / viral filter can be added using the 90 degree expiratory port elbow

Program Objectives
MACS CPAP System self guided tour, objectives completed so far:
Describe the main operating features of MACS
Identify the controls and connections
Describe the patient breathing circuit
With an understanding of MACS’s capabilities, let’s look at patient application.

14. Patient Application Initial Set-up
Attach Airon patient circuit to MACS
Attach a high pressure oxygen hose to the rear of MACS
Attach the other end of the high pressure hose to the oxygen source

15. Patient Application Set % Oxygen Control
Set % Oxygen control to the desired oxygen level
All breaths receive set oxygen level + 10%
Oxygen tank time almost doubles with 65% setting
Caution - with rapid, large tidal volumes on 100% oxygen, the actual delivered percentage may be less than 100%

16. Patient Application Start CPAP Turn on oxygen source
Attach patient breathing circuit to the patient using either a mask or endotracheal tube
Adjust the CPAP control to the level desired
If the patient is not attached to the circuit, or there is a large leak, a high flow of gas will occur

17. Patient Application Monitor patient Assess per your protocol
patient breathing rate
comfort
oxygenation
CO2

18. Let’s look at various clinical environments for CPAP application
Clinical Issues
Let’s look at various clinical environments for CPAP application
Using CPAP
Pediatric support
Medication nebulization
CO2 monitoring
Altitude operation

19. Clinical Issues Using CPAP
Used on spontaneous breathing patients in respiratory failure including
Congestive Heart Failure (CHF)
COPD and Asthma
Near Drowning
CO poisoning
Set CPAP level as needed
Can be used with mask or ET-Tube

20. Clinical Issues Pediatric Support
MACS is safe for pediatric - adult patients
Use the lowest possible settings
Monitor closely for patient synchrony

21. Clinical Issues Providing nebulized medications
A medication nebulizer may be placed between the patient connection and the patient
Patient will inhale medication during every breath and exhale back out through patient circuit
Expiratory filter may be added for personnel safety

22. Clinical Issues CO2 Monitoring Any type of CO2 analyzer may be used
With in-line style analyzers place the sensor Tee between the patient circuit connection and the patient
With sidestream analyzers place the nasal prong sampling tube under the face mask

23. Clinical Issues Altitude Operation
MACS can be used for air transports in unpressurized cabins up to 15,000 feet
Pressure settings will not change as altitude changes

24. Patient Safety Patient Safety Features
Internal Safety Pressure Release – limits circuit pressure to 40 cm H2O
Anti-Suffocation System – in the event of device malfunction, an internal valve will allow ambient air to enter the patient circuit

25. Cleaning and Maintenance
Clean MACS between patients using a soft cloth and a mild detergent / disinfectant
Do not immerse MACS in water
Disposable patient circuit is for single use application and should not be cleaned, disinfected or reused
MACS should receive preventative maintenance every 2 years

26. Program Objectives MACS CPAP System self guided tour
completed; you should now be able to:
Describe the main operating features of MACS
Identify the controls and connections
Describe the patient breathing circuit
Set-up MACS for patient operation
Define various clinical environments for CPAP application
Clean and maintain MACS
Next Step – consider reviewing the MACS Case Study and completing the competency evaluation
