Pressure Support During Chest Wall Compression

2014-07-23 21:08:34 | BioPortfolio


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.


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

Driving pressure in obese ventilated patients: another brick in the (chest) wall.

Medical and Biotech [MESH] Definitions

A respiratory support system used to remove mucus and clear airway by oscillating pressure on the chest.

Body ventilators that assist ventilation by applying intermittent subatmospheric pressure around the thorax, abdomen, or airway and periodically expand the chest wall and inflate the lungs. They are relatively simple to operate and do not require tracheostomy. These devices include the tank ventilators ("iron lung"), Portalung, Pneumowrap, and chest cuirass ("tortoise shell").

The intermittent delivery of pulses of air pressure (5 -20 cmH2O) to the middle ear space through a TYMPANOSTOMY tube.

Pressure, burning, or numbness in the chest.

Application of positive pressure to the inspiratory phase of spontaneous respiration.
