Oxygen mask management involves several key steps for safe and effective oxygen delivery

1. FACE MASK

2. INTRODUCTION

* Facemask is an interference 4
device between the patient's 4
upper airway and the breathing
system.

* It allows gas administration to
the patient from the breathing
system without introducing any
apparatus into the patient's
mouth.

・ They may be made up of
antistatic material to prevent
ignition of anaesthetic gases.

3. DESCRIPTION

Face masks may be made up of:

-Black Rubber,

-Clear Plastic,

-Elastomeric Materia or Disposable Plastic or
-Combination of these.

4. PARTS OF FACEMASK

Body ( Shell or Dome) Dies

・ Constitutes the main
part of the mask Body

* Transparent facemask
allows observation for
vomitus, secretions ,
blood, lip color, and
exhaled moisture and is
better accepted by a
conscious patient .

Rim

5. Seal (Rim, Flap, Edge)
It comes in contact with the face.

Pad (cushion) type seal
Inflated with air or filled with a

material that will conform to the
face when pressure is applied.

Flap type seal
Flexible extension of the body
that conforms to the contour of

the face. It is pressed onto the
face to create a seal.

Body

Rim

6. Connector (Orifice,
Collar, Mount)

* Present at the opposite
side from the seal.

・ Has a thickened fitting
with a 22-mm internal
diameter.

・ Aring with hooks may be
placed around the
connector to allow a mask
strap to be attached.

7. Face mask-types

1) Anatomical mask

Black rubber
Latex
Plastic

2) Ambu transparent mask

3) Rendell-Baker- Soucek mask

8. ANATOMICAL BLACK RUBBER FACE
MASK

ㆍ Also called

as Connell
mask.

ㆍ Body is
made of

rubber that
rubber that

ㆍ Available in
sizes 0, 1, 2,
3&4.

9. Snuggy Silicone and black rubber
Facemask

* Itis autoclavable soft contoured cuff snug facemasks

* its provides patient's comfort as well as makes for easy cleaning.

* The one piece construction and silicone rubber also allows for
clear view of presence of vomit, patient’s lip color as well as other
oral secretions.

10. Trimar Mask

=。 It is similar to Connell mask.
= It has shallower body & less dead space

Trimar Mask

11. AMBU TRANSPARENT MASK

Made of = =
transparent = =
plastic with

inflatable

cuff fora

seal and

has thumb = =
rest built
into the

body

12. RENDELL-BAKER-SOUCEK MASK

Designed for the pediatric
patients,

Has a triangular body.
Usually available in sizes 00, 0, 1
&2

Has a low dead space i.e.

Aml in size 1 &

8ml in size 2
Adequately fits the child’s face
& no special seal is needed.

Some of these masks are RSuppbxe
scented and may have a pacifier

13. Laerdal Peadiatric Mask

It is made of silicon
rubber

It has an inward curving
circular face seal

It can be boiled or
autoclaved

It has been found to be
better for ventilation of
newborn & paediatric
patients

14. Endoscopic Masks

An endoscopic mask is
designed to allow mask
ventilation while an
endoscope is being used

Port/diaphragm in the
mask body allows a
fiberscope to be
inserted into the nose or
mouth.

A tracheal tube
previously loaded over
the fiberscope can then
be advanced, if desired.

15. Hudson’s Face Mask

It is made of clear plastic & is transparent
= On sides there are air entrainment holes

= It is variable performance mask (i.e FiO2 delivered is
02 flow dependant)

16. TECHNIQUES OF USE

* Smallest mask that is appropriate is the most

desirable as it will cause:
-least increase in dead space

-easiest to hold

-less likely to result in pressure on the eyes.

17. One-hand Method

Mask is holded by dominant hand and placed over
the bridge of the nose and on the chin

The thumb and index finger of the dominant hand
are placed on the mask body and these finger
slightly push downwards to hold the mask to the
face and prevent leak.

The remaining three fingers are placed on bony part
of the mandible to pull the mandible up into the
mask

Use the free hand to squeeze the reservoir bag

18. The middle and ring finger is placed on the mandibular ridge to pull
the jaw backward and extend the neck.
Little finger is placed under the angle of the jaw and pull jaw upward

Digital pressure in region of sub mental triangle is avoided as
it can push the tongue up to the roof & increases obstruction.

19. Two-handed Method

Mask is placed over the bridge of the nose and on
the chin

index finger and thumb distal phalanges of both
hand is placed along the ridges of the mask

The remaining fingers are placed on the mandible

Mandible is pulled up into the mask to perform a
jaw-thrust and chin-lift maneuver

The assistance squeeze the reservoir bag

20. A: Holding the mask with two hands. Esmarch-Heiberg maneuver,
involves dorsiflexion at the atlanto-occipital joint and
protrusion of the mandible anteriorly by exerting a forward
thrust on the rami.

B: The anesthesiologist's chin on the mask elbow can help to
create a better seal between the mask and the patient's face.

21. Complications

Skin Problems:

+ Dermatitis in allergic pts. If rubber is a component of a
face mask, a serious reaction can occur in the patient with
latex allergy.

・ Chemical or gas used for sterilization of reusable masks
can cause allergy.

« Pressure necrosis under the face mask.

Nerve Injury:

・ Pressure injury to underlying nerves.

. Forward jaw displacement may result in stretching nerve
injury.

User Fatigue: cramped hands and tired muscles and limits

the user's ability to perform other tasks specially in obese
and patient with larger head

22. Eye Injury: corneal abrasion may be caused by a face
mask inadvertently placed on an open eye

* Pressure on the medial angles of the eyes and
supraorbital margins may result in eyelid edema,
chemosis of the conjunctiva, pressure on the
supraorbital or supratrochlear nerve, corneal injury,
and temporary blindness from central retinal artery
occlusion

Gastric Inflation of stomach ( So Inspiratory pressure
should be kept<20 cm H20)

Foreign Body Aspiration: occur in case of endoscopic
mask

Postoperative Jaw Pain.
