- An Assisted Cough uses a stomach thrust to help build pressure to produce a cough. This video demonstrates how to do the Assisted Cough technique while seated in a wheelchair. Sandra demonstrates and Renata assists with the stomach thrust with one hand and squeezing the LVR bag with the other hand.
If you are able to squeeze the bag yourself, you can do the bagging while the person assisting positions themselves for the stomach thrust.
Sandra places her wheelchair against a wall with the wheels locked so the pushing pressure doesn’t cause a tip. She has a pillow behind her head to avoid hitting the wall.
Here is the process Sandra and Renata demonstrate:
- the assistant places the palm of her hand below the ribcage and above the belly button
- they establish a signal for when her lungs are full - a wave, but you could also use a nod or blink
- Sandra takes a large breath in through the mouthpiece and holds her air
- the assistant squeezes and Sandra inhales successive breaths of bagged air, 2-5 times
- the assistant counts and says “breathe in” each time
- the assistant squeezes the bag with one hand until the lungs feel full and Sandra signals she cannot hold any more air
- once the lungs are full, and just before removing the mouthpiece from the mouth, the stomach thrust is started
- the assistant then pushes up - with some solid force - but not enough to injure the person
- Sandra coughs as the mouthpiece is removed.
If the Breath Stacking and Assisted Cough is successful, a high flow of exhaled air will occur as the mouthpiece is removed. If mucus is loosened, you might hear a rattling sound or feel congested. Cough out as much mucous as you can and spit it out into a container or tissue. Repeat the whole process 3 to 5 times or until all the mucous is out. Rest in between cycles. Clean the mouthpiece after use.
After Breath Stacking and Assisted Cough you should do two breath holds. The breath hold is done by giving you successive breaths using Breath Stacking. Instead of coughing at the end, hold your breath for as long as possible (3-5 seconds) before exhaling.
You know you’re doing it right when you have these signs:
- The chest rises with each squeeze
- There is no air leaking out around the nose or mouthpiece
- It is getting harder to squeeze the bag with each squeeze.
Not everybody needs the combined Breath Stacking and Assisted Cough all the time. If you have a cold, that’s when you would add an assisted cough as often as every 10 minutes.
If you think the Breath Stacking and Assisted Cough techniques are something you could benefit from, connect with your healthcare team to discuss lung volume testing and how to get the tools and assistance you’ll need to get started.
Do NOT do Breath Stacking if you feel light headed, you have any chest discomfort or pain, you have an upset stomach or if you have low blood pressure.
Remember: These LVR kits are not intended for use as resuscitation bag.
Additional notes for healthcare providers:
- Use of the LVR kit is not recommended in the presence of hemoptysis, recent or current barotrauma, bullous emphysema, severe obstructive pulmonary diseases, hypotension.
- Do NOT use the LVR kit if the individual has an inflated tracheostomy cuff or endotracheal tube.
- Individual assessment and precaution should be taken if any of the following exists: severe reflux, IVC filter, Kyphoscoliosis, or Baclofen Pump.
- An Assisted Cough should not be done for any individuals that are pregnant or that have had recent abdominal surgery or have an abdominal aneurysm.
