Ventilate pt 30-60 seconds between attempts. - After intubation, inflate the cuff - Confirm tube placement w/exhaled CO2 detector. POSTINTUBATION MANAGEMENT: - Secure ET tube - Set ventilator settings - Obtain Chest x-ray - Continue to medicate - Recheck VS and pulse oxtimetry What is a Combitube? CORRECT ANSWERS✅ A dual-lumen, dual-cuff airway that can be placed blindly into the esophagus to establish an airway. If inadvertently placed into trachea, it can be used as a temporary ET tube. There are only two sizes: small adult and larger adult. What is a Laryngeal Mask Airway? CORRECT ANSWERS✅ Looks like an ET tube but is equipped with an inflatable, elliptical, silicone rubber collar at the distal end. It is designed to cover the supraglottic area. TNCC test prepA Questions and answers ILMA, does not require laryngoscopy and visualization of the chords. What is Needle Cricothyrotomy CORRECT ANSWERS✅ Percutaneous transtracheal ventilation. (temporary) Complications include: - inadequate ventilation causing hypoxia - hematoma formation - esophageal perforation - aspiration - thyroid perforation - subcutaneous emphysema What is Surgical Cricothyrotomy? CORRECT ANSWERS✅ Making an incision in cricothyroid membrane and placing a cuffed endo or trach tube into trachea. This is indicated when other methods of airway management have failed and pt cannot be adequately ventilated and oxygenated. Complications include: - Aspiration - Hemorrhage or hematoma formation or both - Lac to trachea or esophagus - Creation of a false passage - Laryngeal stenosis TNCC test prepA Questions and answers How do you confirm ET Tube/Alternative Airway Placement? CORRECT ANSWERS✅ - Visualization of the chords - Using bronchoscope to confirm placement - Listening to breath sounds over the epigastrum and chest walls while ventilating the pt - CO2 detector - Esophageal detection device - Chest x-ray How do you inspect the chest for adequate ventilation?

(Tension pneumothorax) What are you looking for when auscultating lung sounds? CORRECT ANSWERS✅ Absence of BS: - Pneumothorax - Hemothorax - Airway Obstruction Diminished BS: TNCC test prepA Questions and answers - Tension pneumothorax may lead to inadequate stroke volume by displacing inferior vena cava and obstructing venous return to right atrium. - Air embolus may lead to obstruction of pulmonary artery and subsequent obstruction to right ventricular outflow during systole, with resulting obstructive shock Explain Distributive Shock. CORRECT ANSWERS✅ Results from disruption in SNS control of the tone of blood vessels, which leads to vasodilation and maldistribution of blood volume and flow. (Neurogenic and Septic Shock). Neurogenic shock may result from injury to spinal cord in cervical or upper thoracic region. Spinal shock = areflexia and flaccidity associated with lower motor neuron involvement in complete cord injuries; reflexes return with resolution of spinal shock. Septic shock from bacteremia is distributive shock. Endotoxins and other inflammatory mediators cause vasodilation, shunting of blood in microcirculation, and other perfusion abnormalities. What is vascular response? CORRECT ANSWERS✅ As blood volume decreases, peripheral blood vessels vasoconstrict as a result of sympathetic stimulation via inhibition of baroreceptors. Arterioles constrict to increase TPR and BP. What is renal response? CORRECT ANSWERS✅ Renal ischemia activates release of renin. Kidneys do not receive adequate blood supply, renin is release into circulation. TNCC test prepA Questions and answers Renin causes angiotensinogen, normal plasma protein, to release angiotensin I. Angiotensin-converting enzyme from the lungs converts into angiotensin II. Angiotensin II causes: - Vasoconstriction of arterioles and some veins - Stimulation of sympathetic nervous system - Retention of water by kidneys - Stimulation of release of aldosterone from the adrenal cortex (sodium retention hormone) *Decreased urinary output = early sign renal hypoperfusion and an indicator that there's systemic hypoperfusion. Explain adrenal gland response. CORRECT ANSWERS✅ When adrenal glands are stimulated by SNS, release of catecholamines (epinephrine and norepinephrine) from adrenal medulla will increase. Epi stimulates receptors in heart to increase force of cardiac contraction (positive inotropy) and increase HR (positive chronotropy) to improve cardiac output, BP and tissue perfusion. Shock stimulates hypothalamus to release corticotropin-releasing hormone that stimulates pituitary to release ACTH that stimulates adrenal gland to release cortisol. TNCC test prepA Questions and answers Effect of cortisol release is elevation in blood sugar and increased insulin resistance and gluconeogenesis, hepatic process to produce more sugar. Cortisol also causes renal retention of water and sodium, a compensatory mechanism to conserve body water. Explain Hepatic Response. CORRECT ANSWERS✅ Liver can store excess glucose as glycogen. As shock progresses, glycogenolysis is activated by epi to break down glycogen into glucose. In a compensatory response to shock, hepatic vessels constrict to redirect blood flow to other vital areas. Explain Pulmonary Response. CORRECT ANSWERS✅ Tachypnea happens for 2 reasons: 1. Maintain acid-base balance 2. Maintain increased supply of oxygen * Metabolic acidosis from anaerobic metabolism will be a stimulus for the lungs to increase rate of ventilation. Increased RR is an attempt to correct acidosis + augments oxygen supply to maximize oxygen delivery to alveoli. Explain Irreversible Shock. CORRECT ANSWERS✅ Shock uncompensated or irreversible stages will cause compromises to most body systems. - Inadequate venous return TNCC test prepA Questions and answers As ICP rises, CPP decreases, leading to cerebral ischemia and potential for hypoxia and lethal secondary insult. Hypotensive pt w/marginally elevated ICP can be harmful. Slightly elevated BP could protect against brain ischemia in a pt with high ICP. Cerebral ischemia can lead to increased concentration of CO2 and decreased concentration of O2 in cerebral vessels. CO2 dilates cerebral blood vessels = increase blood volume and ICP. What are the early signs and symptoms of increased ICP? CORRECT ANSWERS✅ - Headache - N/V - Amnesia regarding events around the injury - Altered LOC - Restlessness, drowsiness, changes in speech, or loss of judgement What are the late observable signs of symptoms of increased ICP? CORRECT ANSWERS✅ - Dilated, nonreactive pupil - Unresponsiveness to verbal or painful stimuli - Abnormal motor posturing patterns - Widening pulse pressure - Increased systolic blood pressure - Changes in RR and pattern - Bradycardia What is Cushing's phenomenon or Cushing's Reflex? CORRECT ANSWERS✅ Triad of progressive HTN, bradycardia and diminished respiratory effort. TNCC test prepA Questions and answers What are the two types of herniation that occurs with ICP? CORRECT ANSWERS✅ 1. Uncal herniation 2. Central or transtentorial herniation Why does herniation occur? What are the symptoms? CORRECT ANSWERS✅ Because of uncontrolled increases in ICP. S/E's - Unilateral or bilateral pupillary dilation - AsyDimmetric pupillary reactivity - Abnormal motor posturing - Other evidence of neurologic deterioration Define uncal herniation. CORRECT ANSWERS✅ The uncus (medial aspect of the temporal lobe) is displaced over the tentorium into the posterior fossa. This herniation is the more common of the two types of herniation syndromes. Define central or transtentorial herniation. CORRECT ANSWERS✅ A downward movement of the cerebral hemispheres with herniation of the diencephalon and midbrain through the elongated gap of the tentorium. Disruptions of the bony structures of the skull can result in what? CORRECT ANSWERS✅ Displaced or nondisplaced fx's causing CSF leakage b/c of lac to the dura mater, creating a passage for CSF.

(Tension pneumothorax) What are you looking for when auscultating lung sounds? CORRECT ANSWERS✅ Absence of BS: - Pneumothorax TNCC test prepA Questions and answers Some causes: - Cardiac tamponade (may compress the heart during diastole to such and extent that atria cannot adequately fill, leading to decreased stroke volume). - Tension pneumothorax may lead to inadequate stroke volume by displacing inferior vena cava and obstructing venous return to right atrium. - Air embolus may lead to obstruction of pulmonary artery and subsequent obstruction to right ventricular outflow during systole, with resulting obstructive shock Explain Distributive Shock. CORRECT ANSWERS✅ Results from disruption in SNS control of the tone of blood vessels, which leads to vasodilation and maldistribution of blood volume and flow. (Neurogenic and Septic Shock). Neurogenic shock may result from injury to spinal cord in cervical or upper thoracic region. Spinal shock = areflexia and flaccidity associated with lower motor neuron involvement in complete cord injuries; reflexes return with resolution of spinal shock. Septic shock from bacteremia is distributive shock. Endotoxins and other inflammatory mediators cause vasodilation, shunting of blood in microcirculation, and other perfusion abnormalities. What is vascular response? CORRECT ANSWERS✅ As blood volume decreases, peripheral blood vessels vasoconstrict as a result of sympathetic stimulation via inhibition of baroreceptors. Arterioles constrict to increase TPR and BP. What is renal response? CORRECT ANSWERS✅ Renal ischemia activates release of renin. TNCC test prepA Questions and answers Kidneys do not receive adequate blood supply, renin is release into circulation. Renin causes angiotensinogen, normal plasma protein, to release angiotensin I. Angiotensin-converting enzyme from the lungs converts into angiotensin II. Angiotensin II causes: - Vasoconstriction of arterioles and some veins - Stimulation of sympathetic nervous system - Retention of water by kidneys - Stimulation of release of aldosterone from the adrenal cortex (sodium retention hormone) *Decreased urinary output = early sign renal hypoperfusion and an indicator that there's systemic hypoperfusion. Explain adrenal gland response. CORRECT ANSWERS✅ When adrenal glands are stimulated by SNS, release of catecholamines (epinephrine and norepinephrine) from adrenal medulla will increase. Epi stimulates receptors in heart to increase force of cardiac contraction (positive inotropy) and increase HR (positive chronotropy) to improve cardiac output, BP and tissue perfusion. TNCC test prepA Questions and answers Shock stimulates hypothalamus to release corticotropin-releasing hormone that stimulates pituitary to release ACTH that stimulates adrenal gland to release cortisol. Effect of cortisol release is elevation in blood sugar and increased insulin resistance and gluconeogenesis, hepatic process to produce more sugar. Cortisol also causes renal retention of water and sodium, a compensatory mechanism to conserve body water. Explain Hepatic Response. CORRECT ANSWERS✅ Liver can store excess glucose as glycogen. As shock progresses, glycogenolysis is activated by epi to break down glycogen into glucose. In a compensatory response to shock, hepatic vessels constrict to redirect blood flow to other vital areas. Explain Pulmonary Response. CORRECT ANSWERS✅ Tachypnea happens for 2 reasons: 1. Maintain acid-base balance 2. Maintain increased supply of oxygen * Metabolic acidosis from anaerobic metabolism will be a stimulus for the lungs to increase rate of ventilation. Increased RR is an attempt to correct acidosis + augments oxygen supply to maximize oxygen delivery to alveoli. TNCC test prepA Questions and answers As volume of one increases, the volume of another decreases to maintain ICP within normal range. As ICP rises, CPP decreases, leading to cerebral ischemia and potential for hypoxia and lethal secondary insult. Hypotensive pt w/marginally elevated ICP can be harmful. Slightly elevated BP could protect against brain ischemia in a pt with high ICP. Cerebral ischemia can lead to increased concentration of CO2 and decreased concentration of O2 in cerebral vessels. CO2 dilates cerebral blood vessels = increase blood volume and ICP. What are the early signs and symptoms of increased ICP? CORRECT ANSWERS✅ - Headache - N/V - Amnesia regarding events around the injury - Altered LOC - Restlessness, drowsiness, changes in speech, or loss of judgement What are the late observable signs of symptoms of increased ICP?
