Dyspnea can come in many forms, but it is commonly known as shortness of breath or having difficulty breathing. People presenting with dyspnea usually show signs of rapid and shallow breathing, use of their respiratory accessory muscles, and may have underlying conditions causing the dyspnea, such as cardiac or pulmonary diseases.

Catathrenia begins with a deep inspiration. The person with catathrenia holds his or her breath against a closed glottis, similar to the Valsalva maneuver. Expiration can be slow and accompanied by sound caused by vibration of the vocal cords or a simple rapid exhalation. Despite a slower breathing rate, no oxygen desaturation usually occurs.
Shortness of breath (SOB), known as dyspnea (in AmE) or dyspnoea (in BrE), is an uncomfortable feeling of not being able to breathe well enough. The American Thoracic Society defines it as "a subjective experience of breathing discomfort that consists of qualitatively distinct sensations that vary in intensity", and recommends evaluating dyspnea by assessing the intensity of its distinct ...
Respiratory sounds, also known as lung sounds or breath sounds, are the specific sounds generated by the movement of air through the respiratory system. [1] These may be easily audible or identified through auscultation of the respiratory system through the lung fields with a stethoscope as well as from the spectral characteristics of lung sounds.

Difficulty 'catching a breath' Wheeze or whistling sound; typically when breathing in when exercising hard; Throat or upper chest discomfort; Symptoms often start to improve from the time of exercise cessation / reducing exercise intensity; No improvement with standard asthma medication (e.g. salbutamol, albuterol).
Any infection in the mouth, nose, sinuses or throat can cause the bad breath, Hoss explains. This includes localized infections, such as an infected wound, surgical site or dental abscess. Can a ...
Increased perfusion in diseased lung would increase shunting and hypoxemia, resulting in worsening shortness of breath when lying on the affected lung. To maximize function of the healthier lung and to relieve dyspnea, the patient is best to lie on the side of the healthier lung, so that it receives adequate perfusion. Patients with chronic ...
Hypopnea is overly shallow breathing or an abnormally low respiratory rate. Hypopnea is typically defined by a decreased amount of air movement into the lungs and can cause hypoxemia (low levels of oxygen in the blood.) It commonly is due to partial obstruction of the upper airway, but can also have neurological origins in central sleep apnea.
