pyriform fossa
|
On either side of the laryngeal orifice is a recess, (also piriform recess, pyriform sinus, or piriform fossa). The fossae are involved in speech. It is significant as a common place for foreign body entrapment and for "packing" of drugs. It is also a potential space for misplacement of an endotracheal tube.
|
|
epiglottis
|
a leaf-shaped cartilage that prevents food from entering the trachea during swallowing.
|
|
vallecula
|
depression between the epiglottis and the base of the tongue.
|
|
arytenoid cartilage
|
form the posterior border of the glottis, and are an important landmark for endotracheal intubation.
|
|
Sellick maneuver
|
posterior displacement of the cricoid ring to occlude the esophagus and decrease the risk of aspiration.
|
|
Atelectasis
|
collapse of alveoli
|
|
Which mainstem bronchus is straighter, and more likely to be inadvertently intubated.
|
Right mainstem bronchus
|
|
The primary muscle of ventilation is the
|
diaphragm
|
|
Nervous system control of breathing comes from the
|
medulla
|
|
Innervation of the diaphragm comes from the ______________ nerve.
|
phrenic
|
|
The average adult male tidal volume is _______ mL per breath.
|
500 mL
|
|
The average adult respiratory rate is _____-_____ per minute.
|
12-20
|
|
Respiratory rate X tidal volume =
|
Minute volume
|
|
Gas exchange in the alveoli occurs due to differences in partial pressures causing _____________ of gases across the semi-permeable membrane.
|
diffusion
|
|
Normal ETCO2 is ____-____.
|
35-45
|
|
A pulse oximetry reading less than ____ indictes the patient is in serious distress and requires immediate airway intervention.
|
85%
|
|
Normally our brain receives the stimulis to increase respiratory rate and depth when our _____ level ____________.
|
CO2 increases
|
|
Hypoxic drive is caused by _________. In this condition, the patients stimullis to increase rate and depth of ventilations occurs when _________________.
|
COPD, O2 levels decrease
|
|
The most common cause of airway obstruction is the __________.
|
tongue.
|
|
Eupnea is
|
a normal respiratory pattern.
|
|
_______________ respirations are rapid, deep respiration due to diabetic ketoacidosis.
|
Kussmaul's
|
|
Cheyne-Stokes respirations
|
progressively deeper, faster breathing alternating gradually with slowing, shallow respirations. This breathing pattern indicates brainstem injury.
|
|
Central neurogenic hyperventilation
|
Deep, rapid respirations due to increased intracranial pressure.
|
|
Agonal or apneustic respirations
|
Shallow, infrequent, irregular respirations.
|
|
Biot's respirations
|
an irregular pattern of rate and depth of breathing with sudden episodes of apnea.
|
|
Kussmaul's respirations
|
deep, rapid breathing commonly seen in diabetic ketoacidosis.
|
|
Coughing
|
forceful exhalation of a large volume of air from the lungs. It serves as a protective mechanism to expell foreign matter from the lungs.
|
|
Sneezing
|
sudden, forceful exhalation from the nose.
|
|
Hiccups (Hiccoughing)
|
sudden inhalation caused by spasmodic contraction of the diaphragm with spastic closure of the glottis.
|
|
Sighing
|
Slo, deep, involuntary inhalation followed by prolonged exhalation. It serves to re-expand atelectatic alveoli.
|
|
Grunting
|
Forceful exhalation against a partially closed glottis--provides positive end expiratory pressure (PEEP) to keep collapsing alveoli open.
|
|
A pulse oximetry reading of _____% - _____% indicates mild hypoxia.
|
91 -94% SpO2
|
|
Normal pulse oximetry readings are considered anything at or above ______%.
|
95% SpO2
