Appropriate airway management - ✔✔*Steps must be performed in order.

Bypass steps that do not apply.*

a. Open and maintain a patent airway.

b. Recognize and treat airway obstructions.

c. Assess ventilation and oxygenation status.

d. Administer supplemental oxygen.

e.Provide ventilatory assistance.

Upper airway - ✔✔Consists of all anatomic airway structures above the

glottic opening.

*1. Tongue*

,a. Muscular tube that extends from the nose and mouth to the esophagus

and trachea

b. Composed of:

i. Nasopharynx

ii. Oropharynx

iii. Laryngopharynx (hypopharynx)

Lower airway - ✔✔Extends from the glottis to the pulmonary capillary

membrane.

1. *Larynx*

2. *Thyroid cartilage*

3. *Cricoid cartilage (cricoid ring)*

4. *Cricothyroid membrane*

5. *Glottis*

6. *Trachea*

1. Larynx - ✔✔-Complex structure formed by many independent

cartilaginous structures

-Marks where the upper airway ends and lower airway begins

2. Thyroid cartilage - ✔✔-Shield-shaped structure formed by two plates that

join in a "V" shape anteriorly to form the laryngeal prominence

i. Known as the Adam's apple

,ii. More pronounced in men

iii. Can be difficult to locate in obese or short-necked patients

-Suspended from the hyoid bone by the thyroid ligament

-Directly anterior to the glottic opening

3. Cricoid cartilage (cricoid ring) - ✔✔-Lies inferiorly to the thyroid cartilage

-Forms the lowest portion of the larynx

-More prominent in females

4. Cricothyroid membrane - ✔✔-Located between the thyroid and cricoid

cartilage

-Site for emergency surgical and nonsurgical access to the airway

-Bordered laterally and inferiorly by the highly vascular thyroid gland

5. Glottis - ✔✔-Narrowest portion of the adult airway

-Vocal cords are located at the lateral borders of the glottis.

-Epiglottis is located at the superior border of the glottis.

-ET intubation requires visualizing the epiglottis, glottis, and vocal cords

before inserting the ET tube.

6. Trachea - ✔✔-Immediately descends into the thoracic cavity

-Not a straight tube, which is key to understand when placing an ET tube

, The respiratory and cardiovascular systems work together to ensure that: -

✔✔1. A constant supply of oxygen and nutrients is delivered to every cell.

2. Waste products are removed from every cell.

Ventilation - ✔✔-Physical act of moving air into and out of the lungs

1. *Inhalation* is the active, muscular part of breathing.

2. *Exhalation* is a passive process and does not normally require

muscular effort.

Oxygenation - ✔✔-Process of loading oxygen molecules onto hemoglobin

molecules in the bloodstream

-Requires adequate *FiO2 (Percentage of oxygen in inhaled air)*

Respiration - ✔✔-Process of exchanging O2 and CO2-->

1. *External respiration (Also called pulmonary respiration)*: Process of

exchanging O2 and CO2 between the alveoli and blood in pulmonary

capillaries.

2. *Internal respiration (Also called cellular respiration)*: Exchange of O2

and CO2 between the systemic circulation and the body's cells.

Pathophysiology of Respiration - ✔✔-Multiple conditions can inhibit the

body's ability to effectively provide oxygen to cells.
