Genetic Considerations
• Cystic fibrosis (CF): genetic disorder,
typically diagnosed in childhood
• CF has serious pulmonary complications –
thick mucus builds up in lungs

disease in susceptible individuals
• Early recognition, diagnosis, and treatment
of occupational asthma can prevent
pulmonary complications

Auscultating Breath Sounds
• Patient should be upright
• Use the diaphragm of the stethoscope
• Begin at C7 posteriorly and anteriorly from
above the clavicles
• Move steadily from right to left upper and
lower
• Compare breath sounds bilaterally
• Do not auscultate over clothing

Diaphragm - best for higher
pitched sounds, like breath
sounds and normal heart
sounds.
Bell - is best for detecting
lower pitch sounds, like some
heart murmurs, and some
bowel sounds. It is used for
the detection of bruits, and for
heart sounds (for a cardiac
exam, listen with the
diaphragm, and repeat with
the bell).

High-Altitude Pulmonary Edema
(HAPE)
• HAPE – can occur with travel to altitudes
greater than 5,000 feet
• Increasing altitude → decreasing
atmospheric pressure → decreasing
available O2
• Rapid onset of hypoxemia may result
• Compensatory increased respiratory rate
may contribute to fatigue

High-Altitude Pulmonary Edema
(HAPE)
• This causes further respiratory
insufficiency
• Initial compensatory mechanisms –
pulmonary vascular vasoconstriction
• Later, inflammatory mediators cause
vasodilation

Percussion
• Assess presence of air, fluid, solid mass in
underlying tissues
• Normal lungs produce a resonant, low-pitched clear
sound
• Hyperresonance indicates airways are hyperinflated
or air is present outside of lung tissue
• Dullness indicates that air is absent
– Pneumonia, pleural effusion, hemothorax, solid
tumors

patient’s oxygen saturation
– End-tidal carbon dioxide levels
– Peak flow is utilized to trend treatment
effectiveness in patients with asthma

Peak Flow Meters
• Track trends in a patient’s condition,
evaluate air movement to determine
severity of asthma exacerbation
• Measure the peak expiratory flow rate

green zones to determine the severity of
decrease in peak flow

Pathophysiology and
Clinical Manifestations of PE
• A pulmonary occlusion occurs when a
bloodborne substance occludes a branch
of the pulmonary artery and obstructs
blood flow
• Hemoptysis, dyspnea, and chest pain
• Pleuritic chest pain, chest wall tenderness,
a pulmonary friction rub, or hypotension

Nursing Management of PE
• The nursing process guides the nursing
care for patients with a PE
• Evaluation of risk factors on admission
and throughout the patient’s hospital stay
• Initially clients may be on bed rest
• Nurses should encourage maximal
mobility, including range of motion and
walking where appropriate while also
staying alert to symptoms of DVT

perfusion and impaired gas exchange
• Assist the patient to maintain the
therapeutic regime during the acute period

anticoagulants

• Perfusion (Q) – the movement of blood
carrying oxygen
• Near equal relationship of ventilation
(4L/min) and perfusion (5L/min)

caused by mismatch of ventilation and
perfusion

Differentiating CPE/Non-CPE
• Mostly evident in cardiac assessment, skin
appearance
– Example 1: tachycardia with hypotension and
cool diaphoretic skin suggests CPE
– Example 2: tachycardia with hypertension,
bounding pulses and dry skin suggests NCPE

– Jugular Vein Distension more common in
CPE
– If coronary artery catheter is used, Pulmonary
Artery Occlusion Pressures (PAOP) or
Pulmonary Capillary Wedge Pressure
(PCWP) above 18mmHg confirms CPE

volume
• Delivers specified volume, pressure, or
both
• Controls concentration of oxygen

Common Ventilator Modes
• Mode: describes the pattern of breath
delivery
• Common modes
– Assist control mode (ACM)
– Synchronized mandatory intermittent
ventilation (SIMV)
– Pressure support (PS or PSV)
– Pressure controlled ventilation (PCV)

Assist Control Mode
• ACM delivers a preset volume or a preset
pressure for each breath
• Patient can trigger a breath or the breath
can be time triggered (CMV, A/C)
• Commonly used in care of in the
postoperative patient

Assist Control Mode
• Nursing Implications of ACM
– As patient awakens, she or he may begin
initiating breaths
– Machine may not have time to deliver set
volume
– Patient can become hypoxic by attempt to
breathe faster, stacking breaths
– Pressure builds; lungs may be injured

machine are working together

Synchronized Intermittent
Mandatory Ventilation
• Very common mode in US
• SIMV sets the mandatory respiratory rate
(VE )
• Ventilator will deliver a set volume or
pressure
• Patient can also initiate a breath
– Ventilator waits for the patient, to breathe
– Synchronizes delivery of breath in concert
with the patient

Synchronized Intermittent
Mandatory Ventilation
• Nursing Implications of SIMV
– Desirable for patient to “overbreathe” the
machine; i.e. breathe faster than the VE
– In SIMV, patient may initiate breaths, some
are assisted and some are not
– Team should evaluate VE, level of sedation or
analgesia

Pressure Support
• PS is a form of assisted ventilation
• Requires stable respiratory effort from
patient
• IF ventilator senses negative pressure on
inspiration
– THEN ventilator supports the patient-initiated
breath

Pressure Support
• Does not control the rate or tidal volume
– Therefore, usually used with SIMV, CPAP
mode
– PS not triggered unless patient breathes
above the VE (mandatory rate)

Pressure Support
• Nursing Implications of PS with SIMV
– If patient does not “overbreathe” the machine,
no benefit from PS
– The nurse should assess the patient and talk
to the team to determine a course of action

Pressure Control Ventilation
• Clinician sets rate and pressure
• Tidal volume is allowed to vary
• Usually reserved for patients with
noncompliant lungs, difficult to ventilate
and oxygenate
• Gas delivery distinguishes PCV from PS
– Breath triggers rapid delivery of gas to reach
set pressure, then the flow is decelerated

Pressure Control Ventilation
• Nursing Implications of PCV
– The nurse should trend the VE and the
expiratory volume over time
– Volume decrease may indicate lungs are
becoming less compliant
– Adjust Pressure to Achieve the Same Volume

Positive End-Expiratory Pressure
•
•

•
PEEP is a ventilator setting, not a mode
Provides resistance at end of exhalation
Prevents alveoli from collapsing
CPAP – continuous positive airway
pressure – related to PEEP

Three Types of PEEP
•
•
•
•
Physiological PEEP – 5 cm of H2O
Treatment PEEP – >5 cm of H2O
Auto-PEEP
For most ventilated patients, PEEP of at
least 5 cm of H2O required to prevent
alveolar collapse

Nursing Implications of PEEP
• PEEP of greater than 5 cm of H2O can
cause decreased cardiac output
• Pneumothorax at higher levels of PEEP
• The nurse should be aware of the level of
PEEP

Auto-PEEP
• Potential problems
– Ventilator set rate is too high
– Overaggressive use of an Ambu bag
• Result: pressure builds in the lungs
– Disconnect the ventilator or Ambu briefly
– Allows the excess pressure to dissipate
