- Chronic obstructive pulmonary disease (COPD)
- Pulmonary embolism

Acute or worsening heart failure
Heart failure is a condition in which the heart can't pump enough blood to meet the body's needs.

Hyperventilation syndrome is a type of anxiety or panic attack, where the primary symptom is fast, shallow breathing that leads to a drop in carbon dioxide levels in the blood. This drops changes the body chemistry and causes the discomfort.
Any sort of fear or excitement that might provoke an anxiety attack can bring on hyperventilation syndrome.
Symptoms are worse in some patients than in others, but include anxiety; lightheadedness; pain and constriction in the chest; numbness and tingling of the extremities; and a feeling of suffocation.
It is important to seek treatment for hyperventilation syndrome, because the symptoms can be debilitating and interfere with quality of life.
Diagnosis is made through detailed patient history, as well as a complete physical examination and lab tests to rule out any other conditions.
Treatment involves showing that patient that, during an anxiety attack, simply breathing into a paper bag for a few minutes will ease the symptoms and allow recovery. Psychological counseling, with an emphasis on managing stress, is also helpful.
Top Symptoms: anxiety, shortness of breath, dizziness, racing heart beat, chest pain
Symptoms that always occur with hyperventilation syndrome: rapid, deep breaths
Symptoms that never occur with hyperventilation syndrome: shortness of breath after a few stairs

Treatment for Trouble Breathing at Night/When Lying Down
When to see a doctor
Completely treating orthopnea requires treating the condition that is causing it. The following may specifically be recommended or you can ask your physician about them.
- CPAP: A continuous positive airway pressure machine can help you breathe during sleep.
- Ask if there is a dental device that could help you
Even if your shortness of breath when lying down cannot be cured, there are many steps you can take to . If you are experiencing relatively benign (not life-threatening) orthopnea, one of the best practices is to avoid sleeping or lying flat on your back. Understandably, this can be a difficult adjustment for back sleepers. You might fall asleep on your side, but that doesn't mean you will stay on your side. An unusual approach to help you stay off your back is to attach tennis balls to the back of your nightshirt. You can actually buy one pre-made if you prefer. You can also try the following.
- Sleep in a semi-reclined position
- Wear nasal strips
- Lose weight: There are many health professionals out there who can help you achieve this goal if you are struggling.
When it is an emergency
Seek immediate medical care if you have orthopnea and any of the following.
