Pressure Support During Chest Wall Compression

July 1, 2010 updated by: Hospital de Clinicas de Porto Alegre

Increasing Pressure Support During Chest Wall Compression is Useful During Respiratory Therapy?

The purpose of this study is to compare two physiotherapy techniques: chest wall compression versus chest wall compression plus increase of 10 cmH2O in inspiratory pressure.

Detailed Description

  1. After being placed in the supine position in bed, with head angle elevation at 30°, patients were randomized to:group 1 (G1): chest wall compression for ten minutes in chest or group 2 (G2): chest wall compression plus increase of 10 cmH2O in IP in PSV for ten minutes in chest.
  2. Clinical variables and APACHE II were registered.
  3. Parameters analyzed at the beginning (1) and at the end (2) of the protocol were: variation of peak pressure (ΔPp=Pp2-Pp1),variation of tidal volume (ΔVT =VT2-VT1), variation of dynamic compliance (ΔCdyn= Cdyn2-Cdyn1).
  4. The amount of variation of mucus secretion aspirated (ΔSa= Sa2-Sa1) at the end was also measured

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Time Frame
Variation of mucus secretion aspirated.
Time Frame: Two years
Two years

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Hemodynamic and pulmonary parameters.
Time Frame: Two years
The hemodynamic and pulmonary parameters were collected: Hart rate (HH), respiratory rate (f), mean arterial pressure (MAP) and peripheral arterial saturation of oxygen (SpO2); peak inspiratory pressure (Ppeak),and Tidal volume (VT) measured in the ventilator, dynamic compliance (Cdyn calculated through the formula VT/ Ppeak - PEEP)
Two years
