CURRENT PRACTICES OF PHYSIOTHERAPY IN ICUs: Saad Saleem B.S.(PT), M.Sc.(PT )
A treatment intervention employed for improving pulmonary hygiene including positioning , chest percussion , vibration and manual hyperinflation to assist in mobilizing secretions in the lungs from the peripheral airways into the more central airways so that they can be expectorated or suctioned out . Chest Physiotherapy is…
Prophylactic - Pre-operative high risk surgical patient - Post-operative patient who is unable to mobilize secretions - Neurological patient who is unable to cough effectively - Patient receiving mechanical ventilation who has a tendency to retain secretions - Patients with pulmonary disease , who needs to improve bronchial hygiene Indications
…cont. Therapeutic - Atelectasis due to secretions - Retained secretions - Abnormal breathing pattern due to primary or secondary pulmonary dysfunction - COPD and resultant decreased exercise tolerance - Musculoskeletal deformity that makes breathing pattern and cough ineffective Indications

Positioning
Physiological Effects of Positioning Optimizes oxygen transport by improving V/Q mismatch Increases lung volumes Reduces the work of breathing Minimizes the work of heart Enhances mucociliary clearance (postural drainage) …cont. Positioning
Postural Drainage isn’t… A separate technique. Its just an example of positioning which has the particular aim of clearing airway secretions with the assistance of gravity . …cont. Positioning
Patients are positioned with the area to be drained the upper most , but modifications should be done wherever necessary. Drainage times vary, but ideally each position requires 10 minutes ( gumery et al, 2001). …cont. Postural Drainage
Positioning restores ventilation to dependent lung regions more effectively than PEEP or large tidal volumes ( Froese & Bryan, 1974). Positioning has a marked influence on gas exchange because of unevenly damaged lungs (Tobin, 1994). Side lying reduces lung densities in the upper most lung ( Brismar , 1985). …cont. Positioning
Right side lying may be more beneficial for cardiac output than left side lying (Wong, 1998). Simply turning from supine to side lying can clear atelectasis from dependent regions ( Brismar , 1985). Positioning affects lung volume Lung volume is related to the position of the diaphragm FRC decreases from standing to slumped sitting to supine ( Macnaughton , 1995) …cont. Positioning
Positioning affects compliance ( Wahba et al found that work of breathing is 40% higher in supine than in sitting) Positioning affects arterial oxygenation by improving V/Q mismatch (V/Q is usually mismatched if the affected lung is dependent- Gillespie et al) “ Bad lung up ” position …cont. Positioning
Life’s most urgent question is: What are you doing for others?
Chest Clapping/Chest Percussion Percussion consists of rhythmic clapping on the chest with loose wrist & cupped hand. Effect: Dislodges & loosens secretions from the lung …cont. Chest Maneuver
Chest Vibration Vibrations consists of a fine oscillation of the hands directed inwards against the chest, performed on exhalation after deep inhalation. Effects : Helpful in moving loosened mucous plugs towards larger airway …cont. Chest Maneuver
Manual Hyperinflation
Was originally defined as inflating the lungs with oxygen and manual compression to a tidal volume of 1 liter requiring a peak inspiratory pressure of between 20 and 40 cm H 2 O (Med j Aust , 1972). More recent definitions include providing a larger tidal volume than base line tidal volume to the patient ( Aust j physiotherapy, 1996) and using a tidal volume which is 50% greater than that delivered via the ventilator (chest, 1994). …cont. Manual Hyperinflation School of Physiotherapy School of Physiotherapy
Indications To aid removal of secretions To aid reinflation of atelectatic segments To assess lung compliance To improve lung compliance …cont. Manual Hyperinflation School of Physiotherapy School of Physiotherapy

Suctioning
Suctioning is the mechanical aspiration of pulmonary secretions from a patient with an artificial airway in place . Indications Inability to cough effectively Sputum plugging To assess tube patency …cont. Suctioning School of Physiotherapy School of Physiotherapy

The suction catheter used must be less than half the diameter of endotracheal tube. The vacuum pressure should be as low as possible. ( 60-150mmHg ) Suction should never be routine , only when there is an indication …cont. Suctioning School of Physiotherapy School of Physiotherapy

ICU rehabilitation has been shown to accelerate recovery ( o’leary & coackley , 1996) Early mobilization for unconscious patients starts right from turning the patient every two hours . ( Brooks- brunn , 1995). Graded exercises can be started as soon as the patient regains consciousness . Mobilization …cont. School of Physiotherapy School of Physiotherapy
Activity is required to maintain sensory input, comfort, joint mobility and healing ability (Frank et al, 1994). Activity minimizes the weakness caused by loss of up to half the patients muscle mass (Griffiths & Jones, 1999). Graded ambulation can be started depending on patients condition Mobilization …cont.
