Chapter 10 - Respiration and Artificial Ventilation Flashcards
The reduction of breathing to the point where oxygen intake is inadequate to support life is called:
respiratory failure.
Signs of inadequate breathing include:
Choices:
A. wheezing, crowing, or gurgling noises.
B. cyanosis of the lips, ear lobes, or nail beds.
C. the patient being unable to speak in full sentences.
D. all of the above.
all of the above.
A 45-year-old is suffering from an acute asthma attack. You expect the patient to have:
decreased tidal volume.
Which of the following methods for providing ventilatory assistance is considered most effective?
Choices:
A. Two-person bag-valve mask technique with high-flow supplemental oxygen
B. Mouth-to-mouth using oxygen
C. One-person bag-valve mask technique
D. Pocket face mask without oxygen
A. Two-person bag-valve mask technique with high-flow supplemental oxygen
Signs of inadequate artificial ventilation of an adult patient include:
Choices:
A. a heart rate that returns to normal.
B. failure of the patient’s skin color to improve.
C. the patient’s chest rising and falling with each ventilation.
D. a ventilation rate of approximately 12 per minute.
B. failure of the patient’s skin color to improve.
If oxygen is connected to a pocket face mask, the setting on the oxygen tank regulator should be set to:
15 lpm.
What device on a bag-valve mask may prevent adequate ventilation?
A pop-off valve
A potential complication of ventilating the patient with a bag-valve mask is:
gastric distension.
Patient conditions that may require supplemental oxygen include: A. shock. B. head injury. C. broken bones. D. all of the above.
D. all of the above.
A nasal cannula should be used to deliver oxygen to a patient who:
will not tolerate a nonrebreather mask.
Safety is of prime importance when working with oxygen; which of the following is therefore true?
Choices:
A. A gasket is not required when connecting the valve to the tank.
B. It is best to open the valve just enough to allow the oxygen to flow.
C. Always store reserve oxygen tanks in a cool and ventilated place.
D. Grease and oil can be used on the valve when attaching it to the tank.
C. Always store reserve oxygen tanks in a cool and ventilated place.
Oxygen cylinder sizes vary, but all are considered “full” when pressure is equal to:
2,000 psi.
An insufficiency in the supply of oxygen to the body’s tissues is called:
hypoxia.
A person exhibiting signs of inadequate breathing is at risk of going into ___________ ___________ .
respiratory failure
___________ ___________ is the reduction of breathing to the point where oxygen intake is not sufficient to support life; when breathing stops completely, the patient is in ___________ ___________ .
Respiratory failure; respiratory arrest
To determine the signs of adequate breathing, you should ___________ for chest expansion, __________ for air, and ___________ for air moving out of the nose and mouth.
look; listen; feel
A blue or gray color to the patient’s skin or nail beds is called ___________ and is a sign of breathing difficulty.
cyanosis
The most difficult part of delivering BVM artificial ventilations is obtaining an adequate ___________ ___________ .
mask seal
___________ - ___________ ___________ are found on older BVMs and may prevent adequate ventilations.
Pop-off valves
BVM systems with an ___________ reservoir can deliver approximately ___________ oxygen.
oxygen; 100%
Venturi masks allow specific concentrations of oxygen by mixing oxygen with ___________ ___________ .
inhaled air
A peak flow rate of 100 percent oxygen at up to 40 liters per minute, and an audible alarm
when the relief valve is activated are features of a(n) ___________ - ___________ , ___________ - ___________ ___________ .
flow-restricted, oxygen-powered ventilation device
Partial rebreather masks allow the patient to rebreathe about one-third of his ___________ ___________ .
exhaled air
The body of a patient with COPD may use low blood oxygen as the factor to stimulate her
to breathe, a condition called ___________ ___________ .
hypoxic drive
A(n) ___________ ___________ is the EMT’s best way to deliver high concentrations of oxygen to a breathing patient because it can provide concentrations of oxygen ranging from ___________ percent to ___________ percent.
nonrebreather mask; 80; 100
Duration of flow from an oxygen cylinder is calculated by subtracting the safe residual pressure (200 psi) from the ___________ ___________ in psi, multiplying it times the constant (based on the size of the tank), then dividing by the ___________ ___________ .
gauge pressure; flow rate
T/F: If a patient’s heart stops beating, breathing may continue for several minutes.
False
T/F: When a patient’s breathing stops completely, the patient is in respiratory failure.
False
T/F: Typical skin coloration is one sign of adequate breathing.
True
T/F: Cyanosis is the term used to describe a blue or gray skin color.
True
T/F: A nonrebreather mask with high-concentration oxygen is the best treatment for a nonbreathing patient
False
T/F: Using a pocket face mask to ventilate a patient delivers a higher volume of oxygen than the bag-valve mask device with a reservoir.
False
T/F: A “pop-off’ valve is an undesirable feature of some older bag-valve mask devices.
True
T/F: Most BVMs have a standard 15/22 mm connection to properly fit face masks and endotracheal tubes.
True
T/F: When using a BVM device, a mask seal can more easily be maintained when ventilations are performed by two rescuers.
True
T/F: Nonbreathing adult patients should be ventilated at a rate of 10 to 12 times per minute.
True
T/F: Using a pocket face mask with supplemental oxygen will deliver nearly 100 percent oxygen concentration to your patient.
False
T/F: A pediatric-size BVM mask can be used to establish a seal around a stoma.
True
T/F: Flow-restricted, oxygen-powered ventilation devices may have an audible alarm when the relief valve is activated.
True
T/F: An automatic transport ventilator is used to supplement a patient’s own weak respirations.
False
T/F: Blind Insertion Airway Devices are safer than other airways because there is no risk of the airway’s becoming dislodged.
True
T/F: When ventilating the patient with a bag-valve mask attached to an endotracheal tube, the EMT must always be conscious to observe and report any changes in the resistance felt when ventilating the patient.
True
T/F: Supplemental oxygen is not generally considered a drug.
False
