Brief summary

To assess the correlations among the physical functional performance, muscle strength, respiratory muscle strength and the ventilator weaning rate.

Detailed description

To assess the correlations among the physical functional performance, muscle strength, respiratory muscle strength and the ventilator weaning rate. Investigators use the DEMMI and FSS-ICU to evaluation the physical functional performance. And MRC score and hand dynamometer to record the muscle strength. The weaning parameters include Pi, PE, RSI,minute ventilation, tidal volume and cuff leak will be recorded. After the participant enters the Respiration Care Center, Doctor and physical therapist evaluate the consciousness and meet the inclusion criteria and the participant will received the first evaluation. The second evaluation will be held before the ventilator weaning timing.

Design outcomes

Primary

MeasureTime frameDescription
correlations between the Change from Baseline 'de Morton Mobility Index (DEMMI)' to the timing before weaning and the ventilator daysfrom baselineto the timing before weaningCorrelations between the Functional physical performance and the ventilator days.It contains 5 items including bed skill, chair skills, static balance, walking and dynamic balance. The scores of 'bed', 'chair', 'static balance', 'walking' range from 0 to 4. And the score of 'dynamic balance' range from o to 3. The sum of 5 items is total raw score. Total Raw score is 0 to 19. And raw score can be converted to DEMMI score, ranging from 0 to 100. Higher values represent better mobility performance.
Correlations between the Change from Baseline 'Functional Status Score for the ICU (FSS-ICU)' to the timing before weaning and the ventilator daysfrom baselineto the timing before weaningCorrelations between the Functional physical performance and the ventilator days.It contains 5 items including rolling, supine-to-sit, unsupported sit, sit-to-stand and ambulation. The scores of 5 items range from 0 to 7. 0 means unable to perform; 1 means total assistance; 2 means maximum assistance; 3 means moderate assistance; 4means minimal assistance; 5 means supervision; 6 means moderate independence and 7 means complete independence. The total score ranges from 0 to 35. Higher values represent better functional performance.

Secondary

MeasureTime frameDescription
Correlations between the Change from Baseline 'grip - hand strength' to the timing before weaning and ventilator daysfrom baselineto the timing before weaningCorrelations between the hand strength and ventilator days. The measurement unit is kilogram(kg). The measurement tool is Jamar® Plus+ Digital Hand Dynamometer. Participant is required to use the best effort to squeeze 15 seconds and repeat 3 times. Resting time is 30 seconds. Investigators record the data and calculate the average data.
Correlation between the Change from Baseline 'Medical Research Council (MRC) scale' to the timing before weaning and ventilator daysbaseline, before weaningMuscle strength assessment. 'Medical Research Council (MRC) scale' is an assessment tool of limb muscle strength. Left and Right sides are all tested. The Upper limb muscle tests include 'shoulder abduction', 'elbow flexion' and 'wrist extension. The lower limb muscle tests include 'hip flexion', 'knee extension' and 'ankle dorsiflexion'. The grades range from 0 to 5. Grade 0 means 'no contraction visible or palpable'; Grade 1 means 'flick of contraction visible or palpable, although no limb movement'; Grade3 means 'movement with gravity eliminated over almost full range of motion'; Grade 4 means 'movement against moderate resistance over full range of motion'; Grade 5 means 'normal power'. The sum of 6 items are total strength score which ranges from 0 to 60. Higher value represents better muscle strength. If the sum is below 48 points, it represents critical illness.
Correlations between the Change from Baseline 'Maximal inspiration pressure(PI)' to the timing before weaning and ventilator daysfrom baselineto the timing before weaningEvaluate the inspiratory muscle strength.Instruct the participants exhale slowly and completely, and then try to breath in as hard as possible. The participants should maintain inspiratory pressure for at least 1.5 seconds and the largest negative pressure sustained for at least one second should be recorded. The unit is cm H2O. Higher value represent better inspiratory muscle strength.
Correlation between the Change from Baseline 'Maximal expiration pressure(PE)' to the timing before weaning and ventilator daysfrom baselineto the timing before weaningEvaluate the inspiratory muscle strength.Instruct the participants inhale slowly and completely, and then try to breath out as hard as possible. The participants should maintain expiratory pressure for at least 1.5 seconds and the largest positive pressure sustained for at least one second should be recorded. The unit is cm H2O. Higher value represent better expiratory muscle strength.
