47
Q

What would you do to improve fio2 level on non breathing ventilated pt ?

A

For pt on ventilator: To improve FiO2 levels in a non-breathing ventilated patient, adjust the ventilator settings to increase the FiO2 percentage delivered.
Contact med control for specific orders.

Ventilated by BVM: Increase ventilations/O2 flow, confirm tube placement.

48
Q

What do gurgling sounds indicate and what do you do about it?

A

Fluid accumulated in upper airway. Adjust body position to drain fluid, suction.

49
Q

What do snoring respirations indicate?

A

Blocked airway. Reposition pt, Open airway.

50
Q

Can you pick out the most accurate statement using dual lumen airway in trauma pts,

A

a dual lumen tube (DLT) can be valuable in trauma situations when lung isolation is needed for procedures like one-lung ventilation, particularly when significant chest injuries or bleeding is present, but its insertion can be challenging due to potential airway instability in trauma patients; meaning it is useful for specific scenarios but may be difficult to place due to the nature of trauma injuries.

51
Q

Pediatric choking victims and what to do if they’re apneic

A

For pediatric choking victims who are apneic Check the child’s mouth for any visible object and try to remove it. Begin CPR immediately. - Use one hand for compressions and proceed with 30 chest compressions followed by 2 rescue breaths. Continue until the child begins to breathe.

52
Q

Going to use a stylette, proper technique in preparing stylette

A

Inserted into the endotracheal tube so that the stylette does not extend beyond the tube’s distal end, ensuring smooth intubation and minimizing trauma. insert it into the endotracheal tube (ETT) ensuring the tip of the stylet does not extend beyond the tube’s distal end, then gently bend the stylet to create a slight curve, often described as a “hockey stick” shape, to help guide the ETT into the trachea during intubation

53
Q

which is a common complication of sedating a pt prior to intubation.

A

​​A common complication of sedating a patient before intubation is respiratory depression, which can lead to hypoxia (low oxygen levels) due to the sedative medication impacting the patient’s breathing rate and depth, potential to take a pt from can ventilate to can’t intubate to can’t ventilate to can’t intubate. Sedation will relax a pt but will not paralyze them. Their gag reflex can remain intact w/ sedation which will still inhibit intubation. Can also cause tongue to occlude the airway which contributes to “can’t ventilate” scenario.

54
Q

performing digital intubation: blind intubation.

A

A digital intubation, also known as a blind intubation, involves using your fingers to palpate and lift the epiglottis within the patient’s airway, guiding an endotracheal tube into the trachea without direct visualization

55
Q

suction- suction cardiac arrest. How to do it properly

A

Suction during cardiac arrest should be performed quickly and efficiently to minimize interruptions in chest compressions. Use a suction catheter to clear the airway of fluids, vomit, or foreign material. Limit suctioning to 10 seconds or less, and resume CPR immediately after clearing the airway. Ensure suction equipment is ready and functioning properly before starting resuscitation.

56
Q

treating ped trauma- hr drops significantly, what caused the drop. Decompensated shock- maybe airway obstruction

A

Hypovolemic shock, cardiac tamponade, tension pneumo, COMPROMISED AIRWAY

57
Q

Infant Airways

A

A child’s airway is smaller in diameter and length. It is also more narrow and flexible. In proportion, the child’s epiglottis is larger and floppier. The narrowest part of the child’s airway is the cricoid cartilage, whereas the adult’s narrowest area in the airway is the vocal cords. The tongue is larger in proportion.

58
Q

know about nasal tracheal intubation-

A

use respirations to guide tube into place
advance as pt’s inhales
vocal cords open widest during inhalation, facilitate placement of tube into trachea
prepare equipment and pre oxygenate pt
insert tube into nostril with bevel to septum
lubricate distal end of tube
normally use right nostril d/t curvature of tube
aim tip of tube straight back toward ear
goal is to follow floor of nasal cavity
do not insert with tip aimed up towards eye, can damage turbinates and cause significant bleeding
As you advance tube, you will hear air rushing in and out of tube as the pt breathes
goal is to place tube just above glottic opening, as pt inhales tube will be sucked into trachea
negative pressure facilitates movement of tube through glottic opening
gently advance tube w/ inhalation
Soft tissue bulge on either side of airway= tube inserted into piriform fossa
hold pt’s head still
slightly withdraw tube
attempt advancement again during inhalation
if no air is moving through tube, likely placed in esophagus
after proper positioning, inflate cuff and ventilate pt
use multiple confirmation methods

59
Q

list of unresponsive- which one needs assisted ventilations-

A

too fast, too slow, not at all, or inadequate depth-

60
Q

math. Evaluating 42 yo f, normal minute volume. How many L of o2 is inspired per min

A

6-8LPM

61
Q

Cardiac arrhythmias can indicate hypoxia, especially in peds

A

bradycardia in peds is typically caused from hypoxia, the Bradycardia then leads to the cardiac arrest, Bradycardia is a late sign of pediatric hypoxia ]

62
Q

which of the following anatomical structures is primary responsibility of the trapped air in asthmatics

A

the bronchioles.

63
Q

Who benefits the most from an advanced airway:

A

Patients who are unable to maintain their own airway due to a decreased level of consciousness, severe trauma, facial injuries, obesity, or other medical conditions that obstruct breathing would benefit the most from an advanced airway, as it provides a secure and controlled method to deliver oxygen and ventilation

64
Q

What would negatively effect alveolar diffusion

A

Thickening of the alveolar membrane makes it less permeable, causes the diffusion process to be more difficult

65
Q

Esophageal dual lumen airway, who to use on, indications, contraindications

A

Esophageal dual lumen airways. Indications: Used in emergency situations where intubation is not possible. - Useful in unconscious patients requiring airway management. Contraindications:- Not recommended if the patient has known esophageal disease. - Avoid if there is an intact gag reflex or risk of vomiting and aspiration.

66
Q

Which one of these devices has a negative feedback on PEEP

A

An endotracheal tube (ETT) is the device that typically has a negative feedback on PEEP

67
Q

Suctioning

A

Tracheobronchial Suction
involves passing suction catheter into E T tube to remove pulmonary secretions
should only be done when necessary
requires strict sterile technique
potential to introduce bacteria into lungs
lubricate French suction catheter before insertion
can inject 3-5ml sterile water into E T tube ot loosen thick secretions
gently inter catheter until you feel resistnce
suction while extracting catheter, in rotating motion
not to exceed 10secs
Once complete, continue to ventilate

68
Q

Patent ventilating non intubated ped pt @ 60x /min what is most likely to happen

A

Hyperventilation could occur, potentially leading to respiratory alkalosis and a decrease in CO2 levels in the blood. This may result in decreased oxygenation due to vasoconstriction

69
Q

sizing npa and opa

A

OPA-corner of the mouth to the angle of the jaw. NPA- measure the distance from the tip of the nose to the tragus of the ear.

70
Q

How to suction through and ET tube

A

Ensure the patient is adequately oxygenated before suctioning.
Insert the suction catheter without applying suction. Gently insert the suction catheter into the ET tube until resistance is met or the patient coughs, indicating the carina has been reached. Do not apply suction while inserting to avoid trauma to the airway. Apply suction while withdrawing the catheter. Re-oxygenate the patient after suctioning.

71
Q

Which unresponsive pt will most likely benefit from an ng tube placed by ems

A

A patient with gastric distention may benefit from an NG tube to decompress the stomach.

72
Q

Adventitious breath sounds in pediatric, lower airway.

A

In pediatric patients, adventitious breath sounds in the lower airway typically manifest as wheezing, a high-pitched whistling sound heard during exhalation, often indicating a narrowing or obstruction in the smaller airways due to conditions like asthma, bronchiolitis, or foreign body aspiration; other potential lower airway adventitious sounds include coarse crackles, which can be heard with fluid buildup in larger airways.

73
Q

Proper procedure in suction apneic adult pts

A

pre-oxygenating the patient with 100% oxygen, rapidly inserting a suction catheter into the airway, applying suction only during withdrawal, limiting suction time to 10-15 seconds per pass, and monitoring the patient’s vital signs closely throughout the process

74
Q

Dual lumen airways, where to inflate first and what to do if you don’t hear BS on first breath

A

Inflate the tracheal cuff first. If breath sounds are not heard, check the tube position and ensure proper ventilation. Adjust or reposition if necessary.

75
Q

Know about using nc and appropriate flow rates

A

Provides low to moderate oxygen enrichment and most beneficial to patients with mild hypoxemia and patients who require long time oxygen therapy. Best used in Spo2 of 90-93%. Flow rates from 1-6 lpm

76
Q

Know at NT intubation and when to advanced the tube

A

insertion of an ET tube into the trachea through the nose. Best for patients that would be difficult or hazardous to preform laryngoscopy, or in the pt’s best interest to not use sedatives. Preformed on responsive patients who are spontaneously breathing but will require definfinitive airway management to prevent further deterioration. Not used on patients who are apneic, suffered head trauma and possibly have mid face fractures. Tube is advanced when the patient inhales.

77
Q

Which of the following is true regarding pulmonary circulation

A

Pulmonary circulation is the process by which deoxygenated blood is transported from the heart to the lungs and back to the heart after oxygenation. This circulation is crucial for gas exchange, allowing carbon dioxide to be expelled and oxygen to be absorbed into the bloodstream. Blood goes through the heart and into the lungs via the pulmonary arteries, in the lungs the hemoglobin becomes oxygenated, and back into the heart via the pulmonary veins, to be circulated into the body.

78
Q

Which of the following is true regarding pulmonary circulation

A

Ventilation: physical act of moving air in and out of lungs
o Inhalation: active part of ventilation
o passive: exhalation part of ventilation
· Oxygenation: process of loading oxygen onto hemoglobin
o Amount of oxygen inhaled must be adequate
o cannot not occur w/o ventilation
· Respiration: process of exchanging oxygen and CO2o External respiration aka pulmonary respiration
§ exchanging oxygen and co2 between alveoli and blood in pulmonary capillaries
o internal respiration aka cellular respiration
exchanging oxygen and co2 between systemic circulation and cells of the body
o oxygenation is required for respiration
§ does not guarantee that respiration is taking place
think “poor perfusion” w/ good ventilation and oxygenation

79
Q

What would be your highest priority when pt is c/c difficulty breathing and also has distended neck veins.

A

the highest priority should be to immediately assess for signs of right-sided heart failure and initiate interventions to stabilize their circulation, as distended neck veins often indicate increased central venous pressure, which is a key sign of right-sided heart failure

80
Q

Know how to clear airway obstructions in 3mo old.

A

5 back slaps, chest compressions until object is dislodged or baby goes unresponsive

81
Q

Peak expiratory flow

A

A test ran to determine effectiveness of treatments. Test should be ran before and after administration of bronchodilator. Have the pt blow 3 times and take the highest reading. Adult average range is 350ml-750ml. Or 550ml.

82

84
Q

resuscitation traumatic cardiac arrest pt, automated vent, pt color no improving, no pulse.

A

If you are resuscitating a traumatic cardiac arrest patient on an automated ventilator, and their color is not improving and they still have no pulse, despite ongoing CPR, this indicates a likely need for immediate advanced interventions like a rapid assessment for potential reversible causes of the arrest, including tension pneumothorax, pericardial tamponade, massive hemorrhage, and consideration for a surgical intervention if necessary

85
Q

Capnography can indicate…

A

adequate cpr, effective ventilations, and rosc. (Capnography. For CPR should read no lower than 15)
