Chronic Disease
• Chronic disease impacts individual’s ability to
perform both daily living tasks of self care
including feeding, eating, and swallowing and
personal and oral hygiene.
• Instrumental activities of daily living as shopping,
preparing meals, and medication management
may also be impaired further compounding risk
to health.
• These impairments require care giving by family
members, non-professional, or professional
caregivers increasing health care burden.

Dysphagia, Aging and Chronic illnesses
• Dysphagia may involve a single or multiple components
of the swallowing mechanism
• Swallowing disorders may occur as an acute or chronic
process, and with sudden or gradual onset
• The aging process appears to impact strength and
timing of the ability to swallow.
• Medical and technological advances enable individuals
to survive chronic illnesses
• Clients with complex medical, respiratory, and

Prevalence and impact of Cortical, Subcortical, and Brain Stem
Infarcts on Swallowing
• 159,000 individuals with stroke will suffer from neurogenic
oropharyngeal dysphagia per year.1
• Neurogenic oropharyngeal dysphagia is a significant sequela of stroke,
and is reported to be present in up to 78% of acute stroke patients. 2
• Oropharyngeal dysphagia with aspiration is identified as a severe
complication of stroke, and is linked to prolonged hospitalization,
medical complications, and mortality.3
• Individuals with dysphagia are discharged twice as frequently to longterm care facilities than are those with stroke without a feeding, eating,
and swallowing disorder complication.

Chronic Obstructive Pulmonary
Disease
• Chronic obstructive pulmonary disease (COPD)
is defined by the Centers for Disease Control

progressive, debilitating respiratory conditions
that include emphysema and chronic
bronchitis.
• Aspiration and COPD is a concern in this highrisk respiratory compromised group.
April 2015
AOTA Nashville, TN
Altered swallowing function with
COPD
• Oral and pharyngeal transit slower than normal, diminished
coordination and strength of the oral and pharyngeal
musculature, and a reduced ability to use pulmonary air to
clear the larynx and ensure airway protection
• Diminished airway protection during swallowing
coordinated with the expiratory phase of breathing
• Consistent laryngeal penetration and aspiration in
individuals with COPD at a higher rate than for normal
subjects at the inspiratory/expiratory transition phase.
• Laryngo- pharyngeal sensitivity is diminished requiring
greater laryngeal adductor reflex input
• Increased pharyngeal residue is present resulting in
increased aspiration risk.

Consequences of
Intubation/Extubation
• In alert postoperative cardiac surgery pts, laryngeal ability
to prevent aspiration is adversely affected after tracheal
extubation, particularly within the first eight hours (Burgess
et al., 1979).
• In a recent systematic literature review, studies that
reported the highest incidence of dysphagia also reported
prolonged intubation times (Skoretz et al., 2010).
• Aspiration detected with Fiberoptic Endoscopic Evaluation
of Swallowing (FEES) in 69% of critically-ill ICU patients post
extubation who demonstrated s/s of aspiration during
bedside eval (Hafner et. al., 2007).

Things to Consider
• Is the patient intubated, on a ventilator or have a tracheostomy tube
and on the ventilator?
• Ask nursing if the patient is requiring frequent suctioning or using the
Yaunker (Oral suctioning) for oral secretions. If this is occurring the
patient is not able to manage their own secretions and a formal
evaluation may need to be delayed
• Can the patient maintain respirations of <32 breaths/minute? (difficult
to coordinate a breathing pattern with increased breaths/minute)
• Has the patient tolerated spontaneous breathing trials (SBT) with use
of trach collar, passy-muir valve, or capped for 2-3hrs. at a time? (SBT
allows for patient’s increased endurance to allow patient to maintain
upright position for meal times)
• If patient is on the ventilator consider trach placement and presence
of bloody secretions (New trach. placement may have bloody
secretions. If grape juice test is done, it may be difficult to
differentiate between grape juice and bloody secretions when
suctioned)
April 2015
AOTA Nashville, TN
Things to Consider
• In chart review consider severity of diagnosis with
regards to dysphagia like; CVA, Ivor Lewis, GERD,
Dementia, s/p surgery or history of dysphagia.
• Check most recent chest x-ray for noted infiltrates.
• If not on ventilator when was patient extubated? Usually
consider trial of oral intake 24 hrs. after extubation
• Be aware of presence of NG tubes.
• Consider and assess patient’s level of alertness/cognition
• Consider patient’s physical/mobilization limitations. Can
they tolerate sitting up in a chair for 1-2 hours for meal
times.

Recommendations to Consider if Patient is not Ready
for a Formal Bedside Dysphagia Evaluation
• Consider use of ice chips following the Mayo Free
Water Guidelines, encourage 1-3 ice chips routinely
to maintain oral moisture
• Make sure to education staff and patients about the
free water guidelines
• Education in oral cares:
• Educate nursing, patient and family with regards to
an oral care routine
• Education in Positioning and oral motor or

Abstract
Methods
The Frazier Water Protocol (FWP) is a part
of dysphagia rehabilitation designed to
allow patients whose diet restriction include
thickened liquids (nectar, honey, or pudding
consistency) to also have water and ice
chips. Use of the FWP remains
controversial due to the concern for
pneumonia. There is limited information
regarding use of the FWP for hospitalized
patients with pulmonary diagnoses and the
FWP is commonly discouraged due to risk
of aspiration.
Inclusion criteria:
• Patient > 18 years of age
• Inpatient admission to the RCU
• Dysphagia evaluation indicating need
for thickened liquids
The FWP used for this study was modified
from its original version and was referred to
as the free water guidelines (FWG). The FWG
allowed for small sips of water and ice chips
between meals with oral cares 3-5 times daily.
Repeat dysphagia evaluations were
conducted at approximate 2 weeks intervals.
All patients remained on the FWG until their
diet was advanced to include thin liquids.
Objectives
The purpose of this study was to evaluate
the FWP in those patients with a
compromised pulmonary status.
Table 1: Study Characteristics
• 14/15 patients (93%) had diet advanced
with repeat dysphagia evaluations
• 1/15 patient (7%) had diet regression
with repeat dysphagia evaluations
• 1/15 patient (7%) was diagnosed with
pneumonia after initiation of FWG.

The Respiratory Care Unit (RCU) cares for
patients requiring a tracheostomy and
mechanical ventilation (MV) following a stay
in a medical or surgical intensive care unit
(ICU). The RCU focuses on ventilator
liberation and rehabilitation needs under the
guidance of a multidisciplinary team.
• The original version of the FWP was
modified to meet the needs of the
patients
• Small sample size
• Use of the FWG with patients had a
low incidence of development of
aspiration pneumonia, therefore,
may play a crucial role for
increasing quality of life for patients
with dysphagia
Conclusions
Provide primary investigation for evidencebased intervention for all medical

Free Water Guidelines
• Oral care/hygiene should be done upon the client awakening
every morning, prior to any oral intake. Brush teeth and/or
dentures 3-5x/day. Rinse and spit whenever mouth is dry.
Keep mouth moist.
• If a client is on a modified diet, that includes thickened liquids,
free water and/or ice chips are allowed between meals, up
until first bite of a meal but restricted until after 30 minutes of
finishing a meal. No water and/or ice chips during meals and
no other thin liquids are allowed other than water.
• If a client requires use of compensatory techniques for safe
oral intake, the client, their family and the nursing staff will be
instructed on these techniques by occupational therapy.

Background
Status Prior to VitalStim
The VitalStim is an FDA approved application of
neuromuscular electrical stimulation to the
swallowing muscles that can be used in dysphagia
rehabilitation. In combination with swallowing
exercises the VitalStim application can be used to
strengthen and re-educate the swallowing muscles
and improve the motor function of the swallowing
mechanism. This application of neuromuscular
electrical stimulation to the swallowing musculature
requires specialty certification in order to use.
Video Study performed June 12, 2013 demonstrated:
• Delayed oral phase, decreased bolus control,
delayed pharyngeal phase, tongue base
weakness, infrahyoid weakness (reduced
laryngeal elevation), poor epiglottic movement,
difficulty managing secretions, and aspiration
• EAT-10, Initial score- 33/40, If the EAT-10 score is
3 or higher, you may have problems swallowing
efficiently and safely
• Functional Oral Intake Scale = Level 0 (No Oral
Intake; Tube dependent)
Results indicate increased risk of penetration and
aspiration due to residual observed in piriform
sinuses; decreased quality of life with regards to
eating, feeding and swallowing; difficulty managing
secretions; and continued use of PEG tube.
Dysphagia: “Difficulty with any stage of swallowing
(oral, pharyngeal, esophageal); dysfunction in any
stage or process of eating; includes any difficulty in
the passage of food, liquid, or medicine during any
stage of swallowing that impairs the client’s ability
to swallow independently or safely.” (Avery, 2010, p.
271)

Placement 2b (Wijting, 2011)
Channel 1: electrodes aligned

belly
Channel 2: electrodes placed at
either side of thyroid notch, over

This particular placement focuses on hypolaryngeal
excursion. It offers good facilitation of geniohyoid,
mylohyoid and thyrohyoid muscles.

TUBE DEPENDENT (levels 1-3)
1. No oral intake
2. Tube dependent with minimal/inconsistent oral intake
3. Tube supplements with consistent oral intake
TOTAL ORAL INTAKE (levels 4-7)
4. Total oral intake of a single consistency
5. Total oral intake of multiple consistencies requiring
special preparation
6. Total oral intake with no special preparation, but must
avoid specific foods or liquid items
7. Total oral intake with no restrictions
Results
Repeat Video Study performed July 12, 2013:
• One incident of flash penetration with honey thick
liquid, patient had penetration above the level of
the vocal cords with thin liquids
• Minimal residual in the valleculae and piriforms
that eventually cleared with second dry swallows.
• Laryngeal excursion was within normal limits.
• The epiglottis did not invert past the upright
position.
• No aspiration was observed with any consistency.
Patient’s Functional Oral Intake improved from Level
1: No Oral Intake to Level 5: Total oral intake of
multiple consistencies requiring special preparation.
Conclusions
This patient was a good candidate for VitalStim
therapy. He had a neurologic diagnosis of a stroke.
He was seen in an outpatient setting and was able to
attend the clinic up to 5 times per week for a month.
Patient had good family support and was able to
follow-through with a home dysphagia exercise
program. Literature supports the use of VitalStim to
assist with increasing speed and strength of swallow
for increased laryngeal elevation.
An initial quality of life question indicated patient
strongly disagrees that eating/feeding provided
pleasure, as he was NPO and receiving tube
feedings. Patient was unable to participate in followup after final Video Fluoroscopic Swallow Study.
Unable to obtain quality of life rating post final Video
Fluoroscopic Swallow Study.
