Shortness of breathor dyspnea is a common symptom. After your doctor asks about your medical history and performs a physical exam,the following tests may be ordered to assess the cause and determine treatment:
- Chest X-ray:ChestX-rayshelp determine whether the cause ispneumoniaor other lung orheartproblems.
- Blood oxygen level test:Also called pulseoximetry, the test helps assess oxygen levels in the blood.
- Electrocardiography:Small electrodes are attached to the chest to measure electrical impulses of the heart and determine blood flow to the heart.
- Lung function test:This test assesses lung capacity and airflow to check how well thelungsare functioning.
- Blood tests:Blood tests help determine whether conditions such asanemia, infections, or heart diseases are causing the symptoms.
Some important aspects to consider during clinical assessment include:
- Smokinghistory
- Body mass index
- Pulse and respiratory rate
- Blood pressure
- Swelling over thefeet, legs or other parts of the body
- Peak expiratory flow rate
When to see a doctor for shortness of breath
Shortness of breath is usually mild and temporary. However, sometimes it indicates an underlying chronic condition that can cause health complications. In such cases, early diagnosis is important.
Consult a doctor for shortness of breath if the condition:
- Interferes with daily activities
- Worsens or does not go away
- Occurs even when at rest
- Is accompanied byfever,chest pain,excessive sweating, orcough
- Leads to bluish or grayish discoloration of the skin, nails, or lips
What are signs of shortness of breath?
Symptoms that may accompany shortness of breath include:
- Laboredbreathing
- Shallow or rapid breathing
- Tightness in the chest
- Wheezingorcoughing
- 心palpitations
- Feeling of being suffocated
What causes shortness of breath?
Shortness of breath has many causes, depending on whether it is acute or chronic. Acute dyspnea occurs over hours or days, whereas chronic dyspnea occurs over weeks or months.
Acute causes:
- Allergies
- Anxiety
- Extreme temperatures
- Chest injury
- Infection
- Choking
- 心attack
- Pulmonary embolism(blood clotting in one or more arteries in the lungs)
- Side effect of a medications (such asstatinsorbeta-blockers)
Chronic causes:
- Asthma
- Obesity
- Chronickidney disease
- Lung disease (chronic obstructive pulmonary diseaseand damage to lung tissues due tosmoking, tumors, orlung cancer)
- Poor cardiovascular health (due to poor circulation, fluids get accumulated in the lungs, making it difficult to breathe)
- Sedentary lifestyle
What are triggers and risk factors for shortness of breath?
Triggers such as environmental pollutants can play a role in shortness of breath. Exposure to the following can trigger frequent episodes of dyspnea:
People who are at a higher risk of dyspnea include:
- Pregnantwomen:Pregnancy倾向于改变女性的呼吸能力,causing about 20% decrease in lung volume.
- Elderly and those with chronic diseases:Older people and people with chronic health conditions or at advanced stages of diseases are at a higher risk of developing the symptom.
- Infants:Pediatric emergencies such as upper respiratory system conditions can lead to dyspnea. Inflammation of theepiglottis, inhaling foreign objects, andcroup也是常见的原因在我呼吸急促吗nfants.
How is shortness of breath treated?
Treatment of shortness of breath depends on the cause of the condition. Shortness of breath can be treated at home in some cases. However, because the condition can cause serious complications such as organ damage and cognitive impairment if not treated properly, it is important to consult a medical professional for proper diagnosis and treatment.
Medical treatment
In serious cases, your doctor may recommend:
- Oxygen therapy:Receiving extra oxygen through the nostrils to ease breathing
- Medications:Drugscalledbronchodilatorscan help relax the airways and alleviatesymptoms of asthmaandCOPD
Home remedies
Home remedies can help alleviate symptoms if the condition is not caused by a medical emergency:
- Pursed lip breathing:This breathing technique helps control shortness of breath caused bychronic obstructive pulmonary disease(COPD),hyperventilation, orpanic attacks. Relax your shoulders and neck muscles and breathe in through your nose. Hold your breath for 2 seconds. Purse your lips as if you are about to whistle and then exhale slowly.
- Diaphragmatic breathing:Diaphragmatic breathing can help you manage shortness of breath caused byCOPD. Sit on a chair with your shoulders, neck, and head muscles completely relaxed. Place a hand on your belly and inhale slowly through your nose. Tighten your stomach muscles and exhale through pursed lips. Continue for 5 minutes.
- Sitting position:Sitting forward in certain positions help relax your body and make breathing easier by creating more space in the chestcavity. Sit on a chair and lean your chest forward slightly. Relax your neck and shoulder muscles and inhale and exhale slowly. Supporting yourself with a pillow can make the breathing process more comfortable.
- Sleeping position:Lay on your side with a pillow between your legs and keep your head elevated. This position helps relax the airways, making breathing easier.
Lifestyle changes
Lifestyle changes can help you manage symptoms of dyspnea and prevent them from recurring:
- Eat a balanceddiet
- Maintain a healthy weight
- Quit smokingand avoid passive smoke
- Avoid environmental triggers
- Build endurance for intense workout sessions
- Make adjustment when traveling to high altitude regions

potassium phosphate/sodium phosphate
Potassium phosphate/sodium phosphate is a medication used to correct lower than normal levels of phosphate in the blood (hypophosphatemia) and in the urine, and to acidify the urine. Potassium phosphate is a combination salt of potassium and phosphorus and sodium is a combination of sodium and phosphorus. Common side effects of potassium phosphate/sodium phosphate include nausea, vomiting, stomach pain, gas (flatulence), diarrhea, tingling and numbness in the mouth (oral paresthesia), sore throat, swelling (edema), lower extremity edema, chest pain, irregular heart rhythm (arrhythmia), excessively slow or rapid heart rate (bradycardia or tachycardia), shortness of breath (dyspnea), and others.
Sleep Related Breathing Disorders
Sleep-related breathing disorders are characterized by disruptions of normal breathing patterns that only occur during sleep. Snoring and sleep apnea are the most common sleep-related breathing disorders.
What Are the Three Types of Asthma?
Asthma is a long-term medical condition that causes breathing difficulties due to airway narrowing, airway swelling, and excessive mucus production in the airway. The common types of asthma include nocturnal asthma, exercise-induced asthma or exercise-induced bronchoconstriction, allergic asthma/seasonal asthma, as well as occupational asthma and cough variant asthma.
What Causes Paroxysmal Nocturnal Dyspnea?
Paroxysmal nocturnal dyspnea (PND) is most commonly associated with heart disease; however, it may also result from respiratory diseases as well.
What Is Breath Sound Assessment?
Clinical evaluation of breath sounds is the first and most common method of assessing lung health. The stethoscope placed on the back and chest lets the physician listen to the breath sounds. This process is called auscultation.whole blood
Whole blood is the entire blood collected from donors that contains all the blood components. Whole blood is primarily used for transfusion in adults with massive blood loss and active bleeding, who generally require all the blood components. Whole blood may also be reconstituted using stored plasma, red blood cells (RBCs), and platelets, usually used for cardiovascular surgeries and exchange transfusions in newborn babies. Common side effects of whole blood include hemolytic transfusion reactions, hives (urticaria), itching (pruritus), wheezing, shortness of breath (dyspnea), low blood pressure (hypotension), and serious allergic (anaphylactic) reactions.
