Chest Physiotherapy in Tracheotomized Patients

Immediate Effects of Chest Physiotherapy in Tracheotomized Patients With Acute Respiratory Distress Syndrome.

Positive expiratory pressure (PEP) breathing is common for treatment of different lung diseases and can increase lung volume and increase elimination of secretion from the airways. Today there is no evidence whether the treatment is effective or not for patients in the intensive care unit. The purpose of this study is to evaluate if PEP breathing can increase oxygenation for patients in the intensive care unit during weaning from the ventilator after acute respiratory distress syndrome.

PEP breathing will be applied on the tracheal cannula for 15 minutes. Measure of the PEP effect will be done before, during and for 20 minutes after PEP breathing.

Study Overview

• Status: Completed
• Conditions: Acute Respiratory Distress Syndrome
• Intervention / Treatment: Procedure: PEP

Detailed Description

Procedure:

To achieve steady state, all subjects are positioned in a semi-recumbent position (30°) for 60 minutes before the start of the intervention and remain in that position during the entire investigation. Subjects are instructed to avoid talking and movements during both steady state and measurements. Airway suctioning (up to 20 kPa) through the tracheal cannula is performed only if there is risk for tube obstruction or if SpO2 decreases below 90%. Frequency of airway suctioning, and number of coughs during the study time are registered. An extra pre-intervention measurement is performed 15 minutes after the first to increase the validity of baseline measurements and control for changes in measured variables due to spontaneous variations.

A PEP device consisting of a one-way valve and exchangeable resistance nipples is used during the PEP breathing treatment. The resistance nipple is chosen at the start of the intervention aiming at an airway pressure of 10-15 cmH2O during tidal breathing (measured with a calibrated manometer). The duration of the PEP treatment is 15 minutes. Complementary oxygen is delivered at the same amount as before the intervention.

Measurements:

The primary outcome is PaO2. Five separate arterial blood samples of 0.7-1.5 ml each (altogether 3.5-7.5 ml for each subject) are drawn from an existing arterial catheter in the radial artery in the left or the right arm by nurses at the ward, and directly analysed.

Subject characteristics are registered from the clinical records, including gender, age, body mass index (BMI), smoking history, duration of invasive ventilation, and length of ICU stay.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change in PaO2	Change from baseline arterial partial pressure of oxygen	Baseline. At 7 minutes and 15 minutes of intervention and 20 minutes post intervention.

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change in PaCO2	Change from baseline arterial partial pressure of carbon dioxide	Baseline. At 7 minutes and 15 minutes of intervention and 20 minutes post intervention.
Change in peripheral oxygen saturation (SpO2)	Change from baseline in SpO2	Baseline. At 7 minutes and 15 minutes of intervention and 20 minutes post intervention.
Change in respiratory frequency	Change from baseline in respiratory frequency	Baseline. At 7 minutes and 15 minutes of intervention and 20 minutes post intervention.
Change in mean arterial pressure (MAP)	Change from baseline in MAP	Baseline. At 7 minutes and 15 minutes of intervention and 20 minutes post intervention.
Change in heart rate	Change from baseline in heart rate	Baseline. At 7 minutes and 15 minutes of intervention and 20 minutes post intervention.
Change in Borg´s Category Ratio 10scale (Borg CR 10 scale) from baseline	Borg CR-10 scale is an eleven point nominal scale that measures patient perceived breathlessness. A higher number indicates a greater breathlessness. 0=no breathlessness. 10 = very very high breathlessness (almost maximal).	Baseline. At 7 minutes and 15 minutes of intervention and 20 minutes post intervention.
