Agonal respiration occurs in 40% of cardiac arrests experienced outside a hospital environment. Patients with cardiac arrests due to problems with the heart were more likely to experience agonal respirations compared to cardiac arrests from a different cause.
Low partial pressure of oxygen in the lungs when switching from inhaled anesthesia to atmospheric air, due to the Fink effect, or diffusion hypoxia. Air depleted of oxygen has also proven fatal. In the past, anesthesia machines have malfunctioned, delivering low-oxygen gas mixtures to patients.
Prolonged apnea refers to a patient who has stopped breathing for a long period of time. If the heart muscle contraction is intact, the condition is known as respiratory arrest. An abrupt stop of pulmonary gas exchange lasting for more than five minutes may permanently damage vital organs, especially the brain.
Problems related to the lungs can cause chest pain that feels worse every time you take a breath. Pneumonia is an infection of one or both lungs caused by bacteria, viruses, or fungi.
Percussion is performed in a systematic matter, from the upper chest to the lower ribs, and resonance is compared between the left and right sides of the chest. This is done from the front and back of the thorax. [14] Percussion over different body tissues results in five common "notes". [14] Resonance: Loud and low pitched. Normal lung sound. [15]
Hypoxia in which there is complete absence of oxygen supply is referred to as anoxia. Hypoxia can be due to external causes, when the breathing gas is hypoxic, or internal causes, such as reduced effectiveness of gas transfer in the lungs, reduced capacity of the blood to carry oxygen, compromised general or local perfusion, or inability of the ...
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.

“The sounds of people chewing gum can really enrage me.” The mom of three explained that if one of her children is chewing or even swallowing too loudly, “my gut reaction is to yell, but I ...
