>> Brief Introduction
Many people with
cystic fibrosis (CF)
and other medical conditions use high-frequency chest wall oscillation
(HFCWO) vests
, otherwise known as
airway clearance systems
, as part of their daily airway clearance routine.
>> Three Working Mode
1.Normal Mode
Under this Mode,working frequency is 1-20Hz,the step value is 1 Hz,Tolerance 5%
2. Ladder Mode
Under this Mode,there are three types vailable. High(9-11-13-15 Hz), Medium (7-9-11-13 Hz), Low (5-7-9-11 Hz).
3. Cyclical Mode
Under this Mode,there are three types vailable.High (9-15 Hz), Medium (7-13Hz), Low (5-11 Hz).
Pressure Range: 3-30mmHg,Step Value: l mmHg,Tolerance ±2mmHg.
Workig Time: 1-99 Min,Step Value lmin,Tolerance ± 30seconds.
>> Operation guidance
Position: Any position is available, while the "Sit" position is better
Time: 2 ~ 4 times per day, 2h before meal or 2h after meal, each time 10-15mins, No over 30 mins.
Suggested Frequency: Adult: 5-22Hz, Child: 5-15Hz
Suggestd Pressure: Adult: 1.5-4.0kPa, Child: 1.5-2.5kPa (1 kPa= 7.5mmHg)
Treatment time: Adult: 1-15min, Child: 1-10min
>> What Are the Advantages and Disadvantages of HFCWO Vest Therapy?
For some, the vest offers a great alternative or addition to
manual chest physiotherapy (CPT)
, but it' s not necessarily the best option for everyone. The decision to use HFCWO therapy or not is a choice based on personal preference and physician recommendations (see chart below).
Advantages | Disadvantages |
Treatment can be done without help. | |
Does not require any skill, so every treatment will be done correctly. | Do not suitable for the people who have wound on the body. |
Freedom to do other things during treatment,
because no special position or breathing techniques are required. |
|
Treats all lobes of the lung at once, so treatment time is shorter than manual CPT. |
>> How Do HFCWO Vests Work?
The goals of HFCWO treatment are the same as with any other airway clearance technique - to break up mucus and help bring it to the upper airways, where it can be
coughed out
or removed by suction.
The machine connected to the vest is an air compressor that delivers bursts of air to rapidly inflate and deflate the vest. This creates gentle pressure and vibration on the chest, which does three things:
1. Breaks up mucus, making it thinner
2. Creates "mini-coughs" in the lungs, which help push the mucus out
3. Makes the cilia move faster, helping them carry the loosened mucus to
the upper airways
