Final answer:
Hiccups are temporary spasms of the diaphragm that result in gasps that are not considered effective for respiration, as they do not aid in the required gas exchange in the lungs.
Step-by-step explanation:
What are temporary gasps that are not considered adequate breathing? Among the options provided: 1) Cough, 2) Sigh, 3) Yawn, 4) Hiccup, the hiccup stands out as a temporary spasm of the diaphragm which can result in a quick intake of breath that is abruptly halted by the closure of the vocal cords, producing the characteristic hiccup sound. This is a reflex action and is not considered effective breathing as it does not contribute to the necessary gas exchange in the lungs.
When observing someone who may be choking, signs to look out for include an inability to speak or cry, labored breathing with gasping or wheezing sounds, clutching at the throat, and possibly turning blue due to a lack of oxygen. Effective respiration is a critical physiological process for oxygen delivery and carbon dioxide removal which ensures every cell in the body can continue to function properly. Hiccups do not fulfill this vital role and are therefore not considered a form of adequate breathing.
