Mechanical ventilation is the use of a ventilator to provide breathing support to patients whose breathing is impaired. There are two main types of ventilation: negative pressure ventilation which uses pressure changes around the chest to drive breathing, and positive pressure ventilation which delivers gas into the lungs through an endotracheal tube.
There are several reasons a patient may require mechanical ventilation including airway obstruction, respiratory failure, or to improve oxygen levels and reduce work of breathing. Key settings on a ventilator include tidal volume, respiratory rate, pressure support, and PEEP. Common modes include assist-control, pressure support, and CPAP. It is important to carefully monitor the patient and ventilator, respond to alarms immediately

A nasopharyngeal airway, also known as an NPA, nasal trumpet (because of its flared end), or nose hose, is a type of airway adjunct, a tube that is designed to be inserted into the nasal passageway to secure an open airway
A mechanical ventilator is a machine that helps a patient breathe (ventilate) when they are having surgery or cannot breathe on their own due to a critical illness. The patient is connected to the ventilator with a hollow tube (artificial airway) that goes in their mouth and down into their main airway or trachea

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

4. Mechanical Ventilation is ventilation of the
lungs by artificial means usually by a
ventilator.
A ventilator delivers gas to the lungs with
either negative or positive pressure.

15. ET tube suctioning removes thick mucus and
secretions from the trachea and lower airway
that you are not able to clear by coughing.
Suctioning is done every 2nd hourly to
improve the oxygenation and to make the
tube patent.

18. Mechanical ventilation in which
various devices that surround the
thorax are used in such a way that
the development
of negative pressure causes
thoracic expansion and thus
inhalation; the release of
the negative pressure allows the
thorax to relax and thus the lungs
to exhale.
18
NEGATIVE-PRESSURE VENTILATORS
22. The basic principle of this ventilator is that a
designated volume of air is delivered with
each breath.
Therefore, peak inspiratory pressure (PIP )
must be monitored in volume modes because
it varies from breath to breath.
22
23. A typical pressure mode delivers a selected
gas pressure to the patient early in
inspiration, and sustains the pressure
throughout the inspiratory phase.
Volume will change with changes in
resistance or compliance, Therefore, exhaled
tidal volume is the variable to monitor
closely.
23
24. High frequency ventilation is a type
of mechanical ventilation which utilizes a
respiratory rate greater than 4 times the
normal value and very small tidal volumes.
High frequency ventilation is thought to
reduce ventilator-associated lung injury (VALI),
especially in the context of ARDS and acute
lung injury. This is commonly referred to
as lung protective ventilation.
24
25. RATE: An optimal method for setting the
respiratory rate has not been established. For
most patients, an initial respiratory rate between
12 and 16 breaths per minute is reasonable
TRIGGER :Sensitivity of breathing. Concerns how
much inspiratory or “trigger” effort is required
from the ventilator to recognize that the patient
is trying to inhale
25
26. TIDAL VOLUME :is the amount of air delivered
with each breath. The appropriate initial tidal
volume depends on numerous factors, most
notably the disease for which the patient
requires mechanical ventilation. tidal
volume is approximately 500 mL per
inspiration or 7 mL/kg of body mass.
(PEEP):positive end-expiratory pressure
26
27. FiO2:Fraction of Inspired Oxygen
PS: Pressure Support
PC: Pressure Control
PIP: Peak Inspiratory Pressure

29. •Delivers pre-set volumes at a pre-set
rate and a pre-set flow rate.
•The patient cannot generate
spontaneous breaths, volumes, or flow
rates in this mode.
•Each patient generated respiratory
effort over and above the set rate are
delivered at the set volume and flow
rate
29
30. Pressure support ventilation is
a spontaneous mode of ventilation also
named Pressure Support Ventilation (PSV).
The patient initiates every breath and
the ventilator delivers support with the preset
pressure value. With support from
the ventilator, the patient also regulates their
own respiratory rate and their tidal volume..
30
31. SYNCHRONIZED INTERMITTENT
MANDATORY VENTILATION
(SIMV)
• Delivers a pre-set number of breaths
at a set volume and flow rate.
• Allows the patient to generate
spontaneous breaths, volumes, and
flow rates between the set breaths.
• Detects a patient’s spontaneous
breath attempt and doesn’t initiate a
ventilator breath – prevents breath
stacking.
31
32. CONTINUOUS POSITIVE AIRWAY
PRESSURE (CPAP)
• This is a mode and simply means that a pre-set
pressure is present in the circuit and lungs
throughout both the inspiratory and expiratory
phases of the breath.
• CPAP serves to keep alveoli from collapsing,
resulting in better oxygenation and less WOB.
• The CPAP mode is very commonly used as a
mode to evaluate the patients readiness for
extubation.

37. If an alarm sounds, respond
immediately because the problem
could be serious.
Assess the patient first, while you
silence the alarm.
If you can not quickly identify the
problem, take the patient off the
ventilator and ventilate him with An
ambu bag connected to oxygen source
until the physician arrives.
Alarms must never be ignored or
disarmed.

•A leak in the humidifier
OXYGEN ALARM
The oxygen supply is
insufficient or is not properly
connected.
40. HIGH RESPIRATORY RATE ALARM
•Episodes of tachypnea,
•Anxiety,
•Pain,
•Hypoxia,
APNEA ALARM
During weaning, indicates that the patient has a slow Respiratory rate and a
period of apnea.
40
41. LOW PRESSURE ALARM
•Usually due to a leak in the
circuit.
•Attempt to quickly find the problem
Bag the patient and call your
INTENSIVIST
41
42. HIGH PRESSURE ALARM
Usually caused by:
•A blockage in the circuit (water condensation)
•Patient biting his ETT
•Mucus plug in the ETT
•You can attempt to quickly fix the problem
•Bag the patient and call for your INTENSIVIST
42
43. 43
Usually caused by:
•Apnea of your patient (CPAP)
•Disconnection of the patient
from the ventilator
•You can attempt to quickly fix the
problem
•Bag the patient and call for your
INTENSIVIST.
45. Role of the -----:
◦ Ensure the Ambu bag is attached to the oxygen
flowmeter and it is on!
◦ Attach the face mask to the Ambu bag and after
ensuring a good seal on the patient’s face; supply
the patient with ventilation.
◦ Bag the patient and call for your DOCTOR.
45
46. Anytime you have concerns, alarms, ventilator
changes or any other problem with your
ventilated patient.
•Call for your Doctor.
NEVER hit the silence button!
