Airway Management, Respiration and Artificial Ventilation Flashcards
The point at which the trachea divides into the two mainstem bronchi is called what?
Carina
Your patient, in whom you have inserted an oropharyngeal airway, is beginning to regain consciousness and develops a gag reflex. What is the proper way of managing this situation?
Turn the patient on their side and remove the airway.
When suctioning the airway, suction should never be applied for longer than how many seconds?
10 seconds
What is the correct method of suctioning?
Insert the catheter or tip to the desired depth prior to applying suction.
What should be kept in mind when assessing and managing the airway of a pediatric patient?
The trachea is easily obstructed by swelling
For life to be maintained, a balance of oxygen and carbon dioxide is needed. The condition when oxygen levels are low is called what?
Hypoxia
The normal stimulus to breathe is stimulated by the chemoreceptors that measure the change of what two gases?
High carbon dioxide and low oxygen
What signs and symptoms would indicate inadequate breathing in a patient?
Increased effort to breathe, cyanosis, cool clammy skin, and an altered mental status
Why is inhalation described as an active process?
It requires chest muscles to contract and use energy to move, creating a negative pressure.
To calculate the minute volume, you need to multiply what 2 measurements?
Tidal volume and respiratory rate
16-yr-old male, labored breathing, increased resp. rate, increased heart rate, leaning forward w/ hands in knees, pink skin, pulse oximetry 96. Patient is suffering from what respiratory condition?
Respiratory distress
28-yr-old male, stabbed in chest w/ hunting knife, air escaping from wound. What is the reason for this?
When the mechanics of breathing are disrupted, a negative pressure cannot be created to pull air through the normal air passages and air is sucked through the wound.
Describe the exchange gas in the alveoli.
Air moves into the alveoli, blood is transported by the pulmonary capillaries, and diffusion occurs.
“Man down” call, scene safe, male, mid-60s, awake, doesn’t acknowledge your presence, diaphoretic, cyanosis of ears and lips, rapid & shallow respirations. What do you do first?
Assist ventilations with a bag-valve mask and supplemental oxygen.
The oxygen flow rate for a nasal cannula should not exceed how many liters per minute?
6 liters per minute
