What's the most important principle in all unconscious patients?
Whether they have an adequate and clear airway or not.
3 multiple choice options
Which part of the brain controls the breathing?
Medulla oblongata
3 multiple choice options
What are the parts of the BVM?
Bag, valve, mask, and oxygen reservoir.
3 multiple choice options
what part of the bag valve mask protects us from infectious diseases?
One-Way Valve protects from infectious diseases.
What are the components of opening an airway such as a jaw thrust and head tilt chin lift?
Jaw thrust: Trauma, lift the jaw using the fingers behind the mandibular angles.
Head-Tilt-Chin-Lift: Medical, Place a hand on the patient's forehead and using firm downward pressure with your palm and tilt the head back.
3 multiple choice options
What are your basic airway management devices?
NPA & OPA
3 multiple choice options
What are the indications and contraindications of an NPA and OPA?
NPA: Intact gag/reflex & unconscious.
OPA: No gag reflex & unconscious.
3 multiple choice options
What is negative pressure?
Negative pressure ventilators sucks air into the lungs by making the chest expand.
3 multiple choice options
What are the benefits of a two-person rescuer ventilation vs a one person rescuer?
More effective mask seal and ventilation. It reduces fatigue and you better control of the airway and bag.
3 multiple choice options
What noises are high-pitched sounds?
Stridor and wheezing
3 multiple choice options
Which noises are upper airway?
Stridor and snoring
3 multiple choice options
What are the upper airway components?
Nasal cavity, nasopharynx, oropharynx, and hypopharynx
3 multiple choice options
What's the difference between internal respiration as far as the cellular level goes and external ventilation?
Internal respiration: occurs in the body tissues, where cells release carbon dioxide and takes in oxygen from the blood.
External ventilation: air coming in and out of the lungs, physical movement of air from the outside environment and into and out of the lungs.
3 multiple choice options
What are the uses for capnography?
It can provide a rough estimate of tidal volume and can be used to monitor airway patency and effective mask ventilation.
3 multiple choice options
What's the difference between aerobic and anaerobic metabolism?
Aerobic Metabolism- first stage of metabolism, requiring the presence of oxygen, in
which the breakdown of glucose yields a high amount of energy. Aerobic means “with oxygen.”
Anaerobic Metabolism- second stage of metabolism, which does not require oxygen, which the breakdown of glucose produces pyru-vic acid and yields very little energy. Anaerobic means “without oxygen.
3 multiple choice options
How is carbon dioxide vs oxygen compared to the type of blood gasses that they'll pull in the ER that are actually the most accurate compared to what we can do in the field?
Carbon dioxide (End tidal): Will be within 5 points if pulled in ER compared to the one on the lifepak (35-45 normal).
Oxygen: Pulse oximetry
3 multiple choice options
What type of devices can be used in the field for capnography?
Capnography monitors, CO2 detectors, nasal cannula, capnometers, and capnographs.
3 multiple choice options
What's the most important concept for any patient in maintaining their airway?
Patency, Positioning, Adjuncts, and Advanced Techniques.
3 multiple choice options
What part of the bag valve mask protects us from infectious diseases?
The one-way valve protects from infectious diseases.
3 multiple choice options
What are positive atmospheric pressures and how does it controls the chest wall rise and fall?
Positive pressure pushes air into the lungs (CPAP,BiPAP, NRB, BVM).
3 multiple choice options
What noises are low-pitched sounds on inhalation?
Rhochi
3 multiple choice options
What noises are cause by snoring respirations?
Snoring
3 multiple choice options
Which noises are lower airways?
Wheezing
3 multiple choice options
Which noises can mean pulmonary edema?
Rales (crackles)
3 multiple choice options
Which noises can mean congestion?
Crackling
3 multiple choice options
Which noises can mean bronchoconstriction?
Wheezing
3 multiple choice options
What is a valve mask & pop-off valves?
A detachable transparent plastic face mask and an oxygen reservoir.
3 multiple choice options
What are the lower airway components?
Trachea, oral cavity, pharynx, bronchi, alveoli, pleura
3 multiple choice options
If we have to find the suprasternal notch, where is it located and why is it important?
The substernal notch is located in the center of the chest, just above the manubrium of the sternum.
It's important because it can help recognise an aneurysm, dissecting aneurysm and atherosclerosis
3 multiple choice options
What happens when people go to high elevations and the effect it has on them being able to breathe as well?
Limit the diffusion of oxygen and produce hypoxia, a state of insufficient oxygen.
3 multiple choice options
What are the benefits of a two-person BMV vs a one-person BVM?
Obtaining and maintaining the mask seal while simultaneously delivering ventilations is more effective with a two-person BVM.
3 multiple choice options
What are the different ways to open the airway?
Head-Tilt/Chin-Lift
3 multiple choice options
What is the anatomy of your lungs, such as bronchioles and alveoli?
Trachea, Bronchi, Alveoli, Mainstem bronchi,
3 multiple choice options
What's the fluid that coats the alveoli that allows the movement of oxygen and carbon dioxide back and forth?
Surfactant
3 multiple choice options
How much oxygen will a BVM deliver if it doesn't have an oxygen tubing connected to it vs if it has high-flow oxygen?
Bag-valve device can deliver 90 to 95 percent oxygen with these flow rates.
3 multiple choice options
What are the settings for a non-rebreather and what percentage of oxygen would it deliver?
10 to 15 L/min providing 90 percent of oxygen.
3 multiple choice options
As well as the cannula 2 to 6 liters and how much they will deliver?
6 to 10 L/min, providing 40 to 60 percent oxygen
3 multiple choice options
What do you do if you're having a hard time bagging somebody?
Check for a proper seal, and check for a clear airway. Listen to lung sounds.
3 multiple choice options
What are the different airway management if you have neck injuries?
Modified jaw thrust with manual inline cervical motion restriction techniques.
3 multiple choice options
What would you expect to find if somebody had a chemical or airway burn and the effects that would have on their breathing internally
Can cause severe respiratory distress by affecting both the airway and lung tissue. The primary effects include swelling, bronchospasm, increased mucus production, and airway obstruction.
3 multiple choice options
What could chemical and airway burn do at the cellular and alveolar damage?
Burns can cause inflammation, necrosis, pulmonary edema, atelectasis, surfactant dysfunction, and interstitial fibrosis.
