“ Unlike inanimate machines that deteriorate with use,
the human body improves with use,
with lack of movement.
Immobility promotes progressive deterioration
of normal body functions…”

Decreased aerobic capacity by 1% daily over 10 days in healthy adults.
These changes in the pulmonary system contribute to:
reduced ventilatory reserve capacity
This adds to the difficulty in weaning ICU pts. from vent.

The Position of the Body Matters
Alters the normal distribution of air & blood
Supine position - overall lung volumes are decreased by 30%
functional residual capacity is decreased due to alveolar closure in dependent lung zones.
Supine: Gravity effects perfusion . More uniform blood flow from base to apex but greater flow is now present in the dependent (dorsal) region.
In a lateral position: blood flow is directed toward the dependent lung.
Unilateral lung process
“ Good lung down” can increase PaO 2 by improving perfusion and ventilation of dependent (good) lung

The V/Q ratio is a delicate balance with normal breathing and normal cardiac index…what if a problem develops???
ALI (acute lung injury)
ARDS (acute respiratory distress syndrome
VAP (ventilator associated pneumonia)
Incidence of ARDS
Approximately 150,000 cases per year 1
25% -38% septic patients develop ARDS
15-30% of trauma patients develop ARDS 2
Incidence of Adult ALI in the US has been estimated at 64.2 cases per 100,000 which appears to be higher than previously reported. ³
Pediatric calculated ALI incidence of 12.8 cases per 100000 person-years 4
Reporting may be underestimated when based on either diagnostic coding or physicians notes 5

ARDS clinical presentation
About 50% of patients who develop ARDS do so within 24 hours of the inciting event
Tachypnea, dyspnea with normal auscultatory lung findings
May precede appearance of infiltrates on chest radiograph
At 72 hours, 85% have a clinically apparent ARDS
Tachycardic with mild cyanosis later develop course rales
Progress to respiratory distress, diffuse rhonchi and signs of consolidation

Overall mortality is 32-45% today vs. 53-68% in the 1980’s ¹
Aggressive management of initiating factors, concurrent infections and improved nutrition may play a role in declining mortality
Age < 55 and trauma etiology have more favorable outcome
Death usually from progressive multi-system failure vs. ARDS ¹
*Decrease in overall mortality rates of approximately 1.1%/yr over the period analyzed (1994 to 2006) ²

ARDS Mortality con’t
Mortality is not related to the initial severity of lung injury, but to the severity of lung injury 72 hours after the initial onset of the syndrome!
Patients with ARDS who develop the complication of pneumonia have a 90% mortality rate.

Ventilator Associated Pneumonia
Second most common hospital acquired infection 1
Leading cause of death from a hospital acquired infection 2
VAP Hospital mortality is 46% vs. 32% of vented patients 2
Increases ICU, vent & hospital LOS 6 - 11.5 days respectively 3

Cumulative VAP incidence 1-3% per day of intubation 2
Respiratory complications are the major reason 1,2
VAP occurred in 47% of patients when re-intubated 2
Average ICU re-admission rate of 7% 3
ICU re-admission’s average HLOS twice as long 3

Results Goldhill, Imhoff, McLean et al. American Journal of Critical Care. January 2007 Volume 16, No. 1
Little evidence on what rotation parameter is effective
Some awake patients do not tolerate steep angle rotation
Effectiveness should also consider
Frequency and duration of rotation
Size and weight of patient
Use of vibration, percussion, or pulsation
Findings Goldhill, Imhoff, McLean et al. American Journal of Critical Care. January 2007 Volume 16, No. 1

Effect the Outcome….
Rapid identification &
aggressive treatment is
vital to patient survival and positive outcome !!!
Ventilator Bundle…or….. BYOBundle?
Peptic ulcer prophylaxis
Sedation lightening, daily awakening
IHI Additional therapy? Oral Care Daily weaning trials Mobility CLRT Proning The VEST
No CLRT Protocol??? 2 days lost!!! Pt admitted on the 21st ??? patient may Continue to deteriorate! The research referenced in this presentation supports early identification and early intervention for patients at risk for pulmonary complications.

MCCG: Keys to Success . . . Begin CLRT within 24 hours of meeting criteria
Target high risk patient populations
Fi02 50% or more longer than one hour
PEEP 8cms or more
P/F ratio < 300
Secretions and dependent edema (interfering with ventilation) settling in bases, (where perfusion is best) inhibiting optimal gas exchange – V:Q mismatch
Begin CLRT before this starts to happen
Pulmonary Risk Assessment
MCCG: Keys to success . . . Implement protocol
Rotate minimum 18 out of 24 hours/day
Customize “%” rotation to maximum amount tolerated
