• Gas supply and distribution system
• Anesthetic work station
• Airway equipment
3. A. Gas supply and distribution system
1.Medical gas cylinder and container:
~ are tanks or cylinder constracted of steel or alloy.
~ It has the ff component;
body
stem
valve
port
4.
5. .
Rules for safe use of cylinder
• Cylinder should handle only by personal who has been trained.
•It shouldn’t store >54 ⁰c
•Valves should be closed all the time
•Store them in cool environment
•Cylinder should be dropped and drag
6. 2.Medical gas pip line system
• It is used to deliver non flamable gases
(oxygen)to anesthetic location.
components:-
* centeral supply
* terminal unit
* hose
* piping
• Oxygen stored as cryogenic liquid at low
pressure or compressed gas in cylinder
• To prevent evaporation ,it should kept below
BP.
7. 3.Suction Equipment(SE)
.The purpose of SE is to remove or collect
solids,gases and liquid from the pt and air way
devices.
.It is an important part of anaesthesia because it is
essential, in intubation to prevent infection and
air way narrowing.
.Components;
~ vacum source ~ pipe
~ vacum ~ pumps
~ receiver ~ vacum inlet

10. 4.OXYGEN CONCENTRATOR
Used to provide oxygen enriched gas for domestic
use.
After being turned the apparatus requiiered 2-
19min to achive max concentration.
- adv; cost saving,contaminant filteration,reliable
and simple.
- dis; maintenace, hazard, water
contamination,device malfunction.
11.
12. B. Anesthetic work station
integrate component nessary for
adminstration of anesthesia.
- it consist ;-
1. anesthetic machine
2.vapolizer
3.ventilater
4.breathing system
5.scavanging system.
14. 2.VAPORIZERS
change liqued to vapour.
most inhalation anesthesia liqud at RT &
atm.pre.
boling point will be lower with low
atm.pres.
TYPES-
concentration calibration
variable by pass vaporizer &
electronic vaporizer

16. 3.BREATHING SYSTEM & GENERAL
PRINCIPLE
BS;-gas path way connected to pt though w/c
gas flow.
-It extend from the poinet of fesh gas inlet to
the point at w/c gas escapes toescavengig
system.
- factors affectBS:= airway;resistance,laminar
and trbulen flow,compliance,rebreathing
18. Contents of BS…..
A. Connecter or adapter:-Intended to join to or
more similar components
B. Filter : protect the patient from MO and air born
particles.
– like dead space and resistance increased, obstruction & leak
impair it’s normal function.
C. Breathing tube: large-bore plastic ,provide a
flexible low resistance flow from one part
to the other.
D. Manual resuscitator: used for patient transport
suctioning and during
administration of anesthesia and MRI.
21. C. Airway equipment
• 1. Face mask:
- allows gas administration from the breathing
system to the patient.
– It is used to administer anesthesia , NPPV
– Today disposal mask is widely used
– Methods of holding mask
• One & two hand method
22.
23. Cont’d…
• 2. Mask strap:
*used to hold the mask firmly on the face.
*Care need to maintain airway.
24.
25. Cont’d
3. Airway :
– It’s purpose is to lift the toungeand epiglotis away
from postrior pharyngeal wall .
– Prevent them from obstructing the space
– Different types of airway
26.
27. Cont’d….
HOW TO USE?
Pharengeal and larengeal reflex should be
depresed
Select size
Airway is insertedwith its concave side facing to
the upper lip
Alternative, airway is inserted with the concave
towards the tongue
28.
29. Cont’d…
4 .bite block
• placed b/n the molar teeth and gum
• prevent teeth from biting on tracheal tube
• avoid dental injury
• in electroconvelsive therapy and in un consciouss
to protect tounge and lip
30. Cont’d….
5. laryngeoscope
• -used to view larynx and adjusent structures
for the perpuse of inserting a trcheal tube
• -detect voice problems , breathing problems
and detect stricture
31.
32. Cont’d…
6 endotracheal tube
• is an instrument inserted through the mouth
down to the trachea
• done under the sedation
Purpuse;-
Serve as an open passage
Provide artifisial respiration,PPV,
- It is inserted with the help of laryngoscopy
33.
34. 6.ETT….
• ETT has the ff xic when it is manufactured
low in cost
Lack of tissue toxicity
Noninflamable
transparency
35. 6.ETT….
• DOUBLE LUMEN ETT(lung isolation device);
in thoracic surgery there are times needed to
isolate and selectively not to ventilate one
lung.
-using aspecial conecter one can not ventilate
one lung and let it collapse yo produse good
surgical acsses
36.
37.
38. 6.ETT….
• Indications for lung isolation
Thoracic surgery
To control contamination or hemorrage
Anatomical consideration
39. 6. ETT..
Broncheal blocker
• Ulternative to using adouble lumen tube
• It is inserted using special conector
• First trachea is inserted with ETT
