Ventilation and Airway Management Flashcards

Front

What should you do if a person starts to vomit while you are giving ventilations?

Back

Turn the person onto their side to prevent airway blockage.

Answer explanation

Turning the person onto their side helps prevent airway blockage from vomit, allowing for safer ventilation. Continuing ventilations or increasing the rate could worsen the situation, while stopping may delay necessary care.

Front

What is the first step if you suspect a person has a head, neck, or spinal injury and is not breathing?

Back

Delegate someone to call for EMS, and immediately check for pulse and begin CPR or rescue ventilations as needed.

Answer explanation

If a person is not breathing and has a suspected head, neck, or spinal injury, the first step is to delegate someone to call for EMS and check for pulse, starting CPR or rescue ventilations as needed.

Front

How should you give ventilations to a person with a stoma?

Back

Keep the airway in a neutral position and use a round infant resuscitation mask.

Answer explanation

For a person with a stoma, it's crucial to keep the airway neutral and use a round infant resuscitation mask, as it fits better around the stoma and allows for effective ventilation.

Front

What technique should be used to deliver ventilations if you do not have equipment?

Back

mouth-to-mouth ventilations

Answer explanation

Mouth-to-mouth ventilations are the appropriate technique for delivering breaths without equipment. This method allows for direct air transfer to the patient, making it essential in emergencies when other devices are unavailable.

Front

What is the approximate oxygen concentration in ambient air?

Back

20%

Answer explanation

The approximate oxygen concentration in ambient air is about 20%. This is a well-established fact, as oxygen makes up roughly 21% of the Earth's atmosphere, making 20% the closest option.

Front

What should you do after each ventilation when giving mouth-to-mouth ventilations?

Back

Open the person's mouth to let air escape.

Answer explanation

After each ventilation, you should open the person's mouth to let air escape. This ensures that the next breath can be delivered effectively without resistance, making it crucial for proper ventilation.

Front

What is the oxygen concentration range a person receives with mouth-to-mouth ventilations?

Back

16% to 17%

Answer explanation

Mouth-to-mouth ventilations typically deliver an oxygen concentration of 16% to 17%. This is lower than atmospheric oxygen levels, which are around 21%, due to the mixing of exhaled air.

Front

What can happen if you do not break the seal and take a breath between ventilations?

Back

The second ventilation may contain a lower oxygen concentration.

Answer explanation

If you do not break the seal and take a breath between ventilations, the second ventilation may contain a lower oxygen concentration, as the air may not be fully replenished, leading to less effective oxygen delivery.

Front

What should you do if you are unable to form a tight seal over the person's mouth?

Back

Use mouth-to-nose ventilations.

Answer explanation

If you can't form a tight seal over the person's mouth, using mouth-to-nose ventilations is a viable alternative. This method ensures that air can still be delivered effectively, maintaining ventilation.

Front

What is the purpose of tilting the head back and pinching the nose during mouth-to-mouth ventilations?

Back

To ensure air enters the lungs.

Answer explanation

Tilting the head back and pinching the nose helps create a seal, ensuring that air flows into the lungs effectively during mouth-to-mouth ventilations, which is crucial for delivering oxygen.
