Study Notes
Equipment of Respiratory Care
- A 2nd year respiratory therapist student, Dr. Mohammed-Senan, with qualifications BS, RCP, FNIV, MSRC, is studying equipment of respiratory care at 21 September University for Medical Sciences.
Medical Gas Pipeline System (MGPS)
- The document details the content, components, and advantages of the Centralized Medical Gas Distribution System (MGPS) in hospitals.
- It introduces MGPS and its components.
- It explains what a Central Medical Gas Distribution System is.
- It provides details of the advantages of a Centralized Medical Gas Delivery System.
- Included are different types of medical gases, their use, and considerations during medical procedures.
Central Medical Gas Distribution System
- MGPS is a central system to supply oxygen (O2), nitrous oxide (N2O), nitrogen (N2), medical air, and medical vacuum safely to different wards in a hospital.
- The system has a color-coded piping system.
- An audio-visual monitoring system is also part of the system to check the situation.
Supply Systems
- Supply systems for medical gases can consist of cylinders (containing gaseous oxygen) or liquefied reservoirs.
- These systems are categorized into continuous and alternating types.
Piping Systems
- Components of a piping system include a central supply, piping extending to where the gas supply is required, and a terminal point.
- Piping systems deliver gas from a central source.
Types Of Systems
- Continuous system: A main, refillable supply reservoir provides gas to the piping system.
- Alternating system: Two sources supply gas to the piping system.
Advantages of Centralized Medical Gas Delivery System
- Eliminates the need for oxygen cylinders at the bedside.
- Reduces noise from moving cylinders.
- Protects sterile areas from contamination.
- Ensures an uninterrupted and clean gas supply at each location.
- Efficient use of space.
- Economically advantageous and hygienic.
Types Of Medical Gases
- Oxygen is used for respiratory therapy and life support, and also in anesthetic procedures.
- Medical air is supplied by a specialized compressor for patient care areas, mainly to reduce excessive oxygen.
- Surgical air, at a higher pressure, powers tools and devices in procedures.
- Nitrous oxide is used for anesthetic and analgesic purposes.
- A mixture of helium and oxygen is used to help treat patients with respiratory or airway obstruction.
- Carbon dioxide is used in laparoscopic procedures to aid in the examination by slightly inflating the stomach for better visibility.
- A vacuum system is also provided for evacuation procedures.
Medical Gas Pipeline System (MGPS)
- Shows various elements of the system including manifolds, control panels and alarm systems.
- Components vary (analog or digital).
Standards and Fundamental Principles
- The system is designed per international standards (IS 7396) to handle pressure.
- Oxygen pipelines are typically painted either white or green with white markings.
- Pressure varies by location (plant, wards, etc).
- Oxygen pipeline systems gradually taper to adjust pressure appropriately.
- Piping systems are segmented into zones for easier monitoring.
Components of MGPS
- Includes pressure regulatory valves, non-return valves, pressure gauges, alarm systems, etc.
Sources
- Bulk systems: These use special vessels, vaporizers, and regulators to supply oxygen, nitrous oxide and carbon dioxide, usually to large hospitals.
- Manifold Systems: High-pressure cylinders are used, with backup cylinders, and control panels, pressure regulators and lights.
- Medical Air Treatment Systems: Employ multiple compressors, receivers, and regulators to supply air.
- Vacuum pumps create a negative pressure in piping systems.
Valves
- Zone and service valves are used to isolate parts of the system for maintenance/modification.
- Area valve service units are placed strategically for gas shut-offs during maintenance without affecting other areas.
- Area alarm panels provide status and pressures information.
Warning and Alarming Systems
- Main and area alarms identify issues, with master monitors tracking main lines and source conditions, and area alarms monitoring specific critical care areas.
Monitoring Systems
- Various monitoring systems capture information about the supply source amounts, manifold operating conditions and provide pressure readings for each area, allowing quick identification of issues.
Alarm System
- Monitors the supply of medical gases, ensuring safe and stable flow.
Outlets and Inlets
- Outlets, where gas is connected, and inlets, where vacuum is connected, have color-coded terminals.
- Two common types: Diamond and Chemetron.
Secondary Equipment
- Hoses, gas flow meters, gauges and vacuum regulators can contribute to gas use.
- Check them during routine inspections.
Pipeline Distribution System Design
- Number of stations depends on the medical facility's needs.
- Flow rates vary by individual stations based on their needs and the care they provide.
- Medical gas outlets and inlets come in varying designs and locations.
Cylinder Manifolds
- A manifold is a pipeline with multiple openings for connecting to cylinders/tanks providing gases.
Manifolds
- Medical gas manifolds are installed to centralize gas supply. Examples include Oxygen.
Pipeline Testing
- Procedures for testing the system, including blowdown, initial/standing pressure tests, purging, and cross-connection tests, are described.
Color Coding for Gas Pipelines
- The color-coding systems for piping for medical gas pipelines according to ISO standards and US conventions and their uses.
Usage of Medical Gases
- Gases required and for what medical areas of a hospital facility.
Terminal Unit
- Design specifics to prevent cross-connections between gas types.
- Identifies different types with their applications.
- A pin-guide system is utilized to avoid cross-connections.
- Uses and availability of different terminal units.
Quick Connector
- Allows for easy connections and disconnections.
- Each has male and female parts with a spring mechanism.
- Hoses color-coded for identification.
Wall/ Special Outlets
- Different types of terminal units (Wall/ Ceiling) are described with their uses.
Safety and Handling of MGPS
- Safety procedures, including training and procedures, for handling and installation are outlined.
Safety Principles
- Importance of correct fittings, adherence to standards, maintaining compliance and proper procedures.
Fire Safety
- Fire safety procedures for hospital facilities, such as fire detection and shutdown systems, linked to local smoke detectors and emergency manifolds.
Precaution Handling of MGPS
- Procedures for safety, including formulating Standard Operating Procedures (SOPs), preventive maintenance, leak tests, and personnel training.
- Discusses handling procedures of pipelines for various types of failure, fire/explosion, and pressure management.
Problems with the Piping System
- Issues such as low/high pressure, leaks, and gas contamination can be issues.
- Solutions to problems are discussed with respect to pipeline.
Medical Gas Piping System
- Schematic diagrams and layouts showing the placement of components of the MGPS.
