Question

You are uncertain whether you have successfully intubated a newborn. Which of the following is an indication that the endotracheal tube is correctly placed in the trachea, and not in the esophagus?

Answer 1

Carbon dioxide detectors indicate expired $CO_{2}$

Explanation:

• Capnography detects the expired carbon dioxide ($CO_{2}$ ) level, which intently approximates intra-alveolar $CO_{2}$ . Capnography detects both wind current and the fractional weight of $CO_{2}$ in alveoli, which is helpful for assessing OSAS, rest hypoventilation, and a hidden pneumonic illness.
• An infrared analyzer over the nose and mouth recognizes  $CO_{2}$ in the expanded air, which subjectively quantifies the wind current.
• Subjective indicators are fundamentally used to at first affirm appropriate situation of an endotracheal tube by exhibiting the nearness (hinting effective position in the trachea) or need (esophageal arrangement) of breathed out  $CO_{2}$ .
• In spite of the fact that $CO_{2}$ identifiers at last measure breathed out $CO_{2}$ ,  there are structure contrasts between certain units. Finders can be partitioned into quantitative and subjective sorts. Subjective locators just show the nearness or nonattendance of $CO_{2}$. The most fundamental unit of this sort is the colorimetric locator creating a shading change as the gas moves through a litmus paper film in the aviation route circuit.
