Medications that can precipitate respiratory impairment include ACE inhibitors, NSAIDs, anticonvulsants, beta blockers, calcium channel blockers, cholinergics, antihypertensives, antibiotics, antifungals, antimicrobials, antiretrovirals, digoxin, interferon, and chemotherapy agents.
Medicines that can increase the risk of respiratory depression include benzodiazepines such as midazolam or diazepam, particularly when used in combination with other psychotropic medicines such as antidepressants, antipsychotics, anticonvulsants or sedatives such as phenobarbital.
While there are many causes of shortness of breath, the most common causes are lung disease, heart disease, or deconditioning (lack of exercise, especially in people who are overweight or obese).
If shortness of breath happens when you're clearly not exerting yourself, when you're doing something you normally could do without feeling winded, or comes on suddenly, those are warning signs that a heart issue could potentially be to blame.
Shortness of breath is often a symptom of heart and lung problems. But it can also be a sign of other conditions like asthma, allergies or anxiety. Intense exercise or having a cold can also make you feel breathless.
Drugs used to treat the respiratory tract include the bronchodilators and anti-inflammatory drugs, drugs that modify respiratory secretions (e.g., mucolytics, mucokinetics, and expectorants), antitussive drugs, and decongestants.
People can experience shortness of breath while walking for a number of reasons. Sometimes, this occurs as a result of conditions such as anxiety, asthma, or obesity. Less commonly, shortness of breath signals a more serious underlying medical condition.
"Chest pain, rapid heartbeat and breathlessness may result when an insufficient amount of blood reaches the heart muscle," says Tung. (See "Symptoms" below.) One of the key distinctions between the two is that a heart attack often develops during physical exertion, whereas a panic attack can occur at rest.
Our experts recommend scheduling an appointment with your doctor if your shortness of breath is accompanied by swelling in your feet and ankles, trouble breathing when you lie flat, high fever, chills and cough, or wheezing. You should also see a doctor if you notice shortness of breath becoming more severe.
Stage 2 of Congestive Heart Failure
Stage two of congestive heart failure will produce symptoms such as fatigue, shortness of breath, or heart palpitations after you participate in physical activity.
Shortness of breath does not equal saturation (SaO2%)
In other words, your level of dyspnea, or air hunger, does not always correlate with your oxygen saturation. This means that you can be short of breath, even extremely short of breath, even in the presence of normal oxygen saturation.
Wheezing: Noisy breathing or wheezing is a sign that something unusual is blocking your lungs' airways or making them too narrow. Coughing up blood: If you are coughing up blood, it may be coming from your lungs or upper respiratory tract. Wherever it's coming from, it signals a health problem.
Shortness of breath occurs when you're not getting enough oxygen, leaving you to feel like you need to breathe harder, quicker and/or deeper. And, if you feel like you're not getting enough oxygen, your organs aren't either — which can have serious short-term and long-term consequences to your health.
Symptoms include shortness of breath or feeling like you can't get enough air, extreme tiredness, an inability to exercise as you did before, and sleepiness.
For quick relief, help the body relax. While sitting, lean forward resting the elbows on the knees. Many people do this naturally. Sitting in front of a fan may help shortness of breath; however, some seniors require oxygen.
Warning signs and symptoms of heart failure include shortness of breath, chronic coughing or wheezing, swelling, fatigue, loss of appetite, and others. Heart failure means the heart has failed to pump the way it should in order to circulate oxygen-rich blood throughout the body.
