1. Terminate the
treatment
*HR increase 20 bpm, adverse
reaction, dizziness
*Stop treatment and notify physician
2. Treatment Technique
a. IPPB (Indication)
1. Increase in work of breathing
2. Hypoventilation
3. Inadequate cough (get air behind secretions)
4. Stiff Lungs
5. Ate1ectasis- sedated post-op and patients recovering from
abdominal surgery
6. Pulmonary edema
b. Incentive Breathing Techniques 1. Patient
sitting upright
2. Twice the patient's
tidal volume
3. Inspiratory Time
should be 5-15 sec, with a 2-3 sec pause
4. Incentive Spirometry is an alternative to IPPB if patient
is able to achieve a Vital Capacity of
more
than 15 ml/kg of body weight
c. Aerosol Therapy
1. Take slow deep breaths
2. Heated nebs are the
greatest source of delivery of contamination moisture to the patient
3. Keep water drained out of the tubing because this will
increase the percent of the oxygen delivered to
the
patient
d. Oxygen Therapy
1. Nasal Cannula
a.
24 to 44 % at flow rates 1 to 6 L/min
2. Simple Mask
a.
35 to 55 % at flow rates 5 to 12 L/min
3. Partial Rebreathing Mask
a. 35 to 60 % at
flow rates 8 to 15 L/min
4. Non-rebreathing mask
a. 60 to 80 % at
flow rates 8 to 15 L/min
5. Venturi
mask
a.
24 to 50 %
6. Aerosol Mask
a.
21 to 100 % at flow rates of8 to 15 L/min
7. T-tube. Briggs adapter
a. 21 to 100 % at
flow rates of 8 to 15 L/min
8. Trach
Mask
a.
35 to 60 % at flow rates of 10 to 15 L/min
9. Oxygen Blender
a. Use 50 psig gas sources to mix or blend oxygen and compressed
air to deliver 21 to 100% at flow
rates
of 2 to 100 L/min
b. Provide a stable Fi02 as long as the outlet flow exceeds
the patient's inspiratory flow demands
e.
Specialty Gas Therapy
1. Helium/Oxygen Therapy (80/20) (70/30)
a. Second light gas;
decrease total density of the gas this allows the gas to pass through
obstructions more
easily
b. Must be delivered in a tightly closed
system to prevent gas from leaking out
~Non-rebreather,
endotracheal tube, tracheostomy tube
c. 80:20 multiply flowmeter reading by 1.8 to determine correct flow d. 70:30
multiply
flowmeter reading by 1.6 to
determine correct flow
f. Bronchial Hygiene Therapy
1. CPT
a. Performed over
each area for 2 to 5 min
b. Posterior basal
segment of lower lobe -Prone, Trendelenberg
c. Lateral basal segment of the lower lobe -1/2
turn, Trendelenberg
d.
Superior Segment of lower lobe -Prone, bed flat, pillow under hips
e. Anterior basal
segment of lower lobe -1/2 turn, Trendelenberg
f. Lateral and medial
segments of the right middle lobe -1/4 turn, Trendelenberg
g. Superior and
inferior lingular segments of the left lung -1/4 turn, Trendelenberg
h. Apical segment
of the upper lobe -Pt sitting upright
i. Anterior
segment of the upper lobe -Supine, bed flat, pillow under knees
j. Posterior segment of the upper lobe
-Sitting upright, leaning forward
2. PEP (RRT only)
a. Effective for
preventing postoperative atelectasis by opening airways and improving gas
exchange
b. PEP levels of 10 to 20 cm H2O are used
c. Patient inhale
a larger-than-normal volume, and then actively exhale: 'riot forcefully, with
expiration lasting 2-3 times longer than inspiration
d. Perform 10 to 20 of these breaths,
remove mask and perform 2-3 huff
coughs
e. Repeat procedure 4-6 times per session
3. Flutter
a. Patient exhales to produce a PEP of
between 10 and 35 cm H2O
b. Patient inhales
slowly, just a bit more than a normal breath (not filling the lungs) and hold
breath for 2-3
seconds
c. Exhale
reasonably fast, not forcefully
d. Oscillations
are transmitted down the respiratory tract, creating vibrations that result in
mobilization
of secretions
e. Should be
cleaned every 2 days in a soap solution and disinfected at
regular intervals
by soaking in a 1:3 solution of vinegar and water for 15 min, dried, and
reassembled for
future use
g. Management of artificial airway
1.
Changing a tracheostomy tube within 48 hours of the tracheotomy is not
advisable and only should be done
by a surgeon~ tracheal rings may recede when the tube is
removed, making reintubation difficult
2. Indication
for suctioning
a. Remove retained
secretions that patient cannot mobilize
b. Maintain
patency of artificial airway
c. To obtain sputum culture and sensitivity
testing
3. Inflate and/or
deflate the cuff
a. Minimal leak technique
~ With stethoscope beside the larynx,
listen for airflow as the cuff is inflated
-Inflate until no airflow is heard, then
withdraw air slowly until a slight leak is heard
b. Minimal occluding volume
:-,
~Same technique, except the cuff is slowly
inflated just to the point where no leak is heard
h. Suctioning
1. Frequency and
duration
a. Suction when needed
2. Size of catheter
a. Divide the inner diameter by 2 and
multiply by 3
b. Yankauer
-Used to suction oropharynx
3. Negative Pressures
a. Adults --80 to -120 mm Hg
b. Children --80 to -100 mm Hg c. Infants --60
to -80 mm Hg
4. Lavage
a. 3 to 5 ml of
normal saline to help thin secretions b. 0.3 to 0.5 ml ~infants
i. Mechanical Ventilation
1. Sensitivity
a. Set so the patient generates -0.5 to
-2.0 cm H2O b. If it take more increase sensitivity
2. Oxygenation
a. Once 60 % Fi02 is reached, Peep should
be added or increased
b. Peep used to maintain positive pressure
in the airway after a vent. Breath
3. Adjust I:E settings
a. Increase tidal volume, increase
inspiratory time b. Increase flow, decrease inspiratory
time
c. Increase
respiratory rate, decrease expiratory time d. Total cycle time = 60/Rate I time
=
TCT/parts
4. Modify
Ventilator Technigues
a. Pressure
Support
-spontaneous
breathing more comfortable by overcoming the high resistance and increase
inspiratory work
caused by the ET tube
-may be used
for patients who are ventilating well but are intubated to protect their airway
of for patients on CP AP with oxygenation deficiencies
b. Pressure
Control
-used for patients with ARDS in which Peep has not improved
ventilation or oxygenation -
Initial
settings
*Fi021.0
*Pip of about 50 % of
that on a volume ventilator
*Tidal volume 6 to 10 ml/kg of ideal body weight
*Peep > 15 cm H2O
*I:E 1:2
-Can be uncomfortable,
so patient should be sedated
5. Adjust noninvasive Positive Pressure ventilation
a. make sure mask
is tight so there is no leak
b. IPAP – EPAP determines Vt in relation
so compliance of lung and airways resistance
EPAP affects PaO2
6. Monitor and adjust
alarm settings
a. Low pressure alarm
-activated by leaks in the ventilator circuit
or by patient disconnection
b. High pressure
alarm
-activated by decrease in lung compliance
-increasing airway resistance caused by
*airway secretions
* bronchospasm
*water in the ventilator
tubing
*kink in the ventilator
tubing
*patient coughing
c. Low PEEP/CPAP alarm
-Activated by leaks in the ventilator circuit
or by patie~t disconnection d. Apnea alarm
-set according to the patient's respiratory
rate
-Activated
after a preset time passes with no inspiratory flow through the tubing
7. Adjust ventilator
settings based on ventilator graphics
a. Flow curve
-Flow remains constant throughout
inspiration
-Change in airway resistance and
compliance won't change the flow pattern
b. Leak
-Volume does not return
to baseline, around the ETT or cuff -Auto-Peep or patient may be
coughing
or agitated
c. Obstructive
-Causes the tracing to be flat during
exhalation as a result of decreased expiratory flows
8. Change mechanical
deadsl2ace
a. Mechanical dead
space may be added to the circuit between the ventilator wye
adapter and
the ET tube adapter to increase PaCo2 levels
b. For every 100 ml of
dead space, PaCo2 increases approximately 5 mm Hg c. Added to the
circuits
of patients on control or assist/control modes only d. Never add dead space if
the
patient
is on SIMV, IMV, or CP AP
