Auscultation
Explanation:
Auscultation is the act of listening with a stethoscope to sounds produced within the body. This technique is used to listen for blood pressure, heart sounds, lung sounds, and bowel sounds. Inspection is the process of performing deliberate, purposeful observations in a systematic manner. It uses the senses of smell, hearing, and sight. The hands and fingers are sensitive tools of
palpation and can assess temperature, turgor, texture, moisture, pulsations, vibrations, shape and masses, and organs. Percussion is used to assess the location, shape, and size of organs, and the density of other underlying structures or tissues.
Stridor is a continuous high-pitched, monophonic, inspiratory crowing sound. The sound originates in the larynx or trachea from an upper airway obstruction because of swollen and inflamed tissues. The sound is louder in the neck than over the chest wall. Crackles are discontinuous, high-pitched, short crackling or popping sounds heard during inspiration. They are not cleared by coughing and are caused by fluid in the lungs. Coarse rales are loud, low-pitched, bubbling, and gurgling sounds that start in early inspiration and are caused by pulmonary congestion. Sonorous rhonchi are low-pitched, monophonic, single-note, musical snoring and moaning sounds. They are heard throughout the cycle, but are more prominent on expiration. They may be cleared by coughing.

Asthma is an allergic hypersensitivity characterized by bronchospasm and inflammation, edema in the walls of the bronchioles, and secretion of highly viscous mucus into the airways. These greatly increase the airway resistance, especially during expiration, and produce the symptoms of wheezing, dyspnea, and chest tightness. During a severe attack, there is an increased respiratory rate, shortness of breath with audible wheezes, use of accessory neck muscles, and cyanosis.
