CPAP: What Do You Know About Continuous Positive Airway Pressure?

1.

Which medical condition is the primary indication for CPAP?

A.

CHF with Pulmonary edema
B.

Acute MI
C.

COPD, prior to the use of bronchodilators
D.

Unconscous Asthma

Correct Answer
A. CHF with Pulmonary edema

Explanation
CPAP, or continuous positive airway pressure, is primarily indicated for CHF with pulmonary edema. CHF, or congestive heart failure, is a condition in which the heart is unable to pump enough blood to meet the body's needs. Pulmonary edema is a buildup of fluid in the lungs, which can occur as a result of CHF. CPAP is used to treat this condition by delivering a continuous flow of air pressure to keep the airways open and improve breathing. Acute MI, COPD, and unconscious asthma are not the primary indications for CPAP.

2.

You are transporting a patient in florid Pulmonary Edema, secondary to CHF. CPAP has been applied, and you have a 10-minute transport time. Which of the following would cause you to stop CPAP treatment?

A.

The patient becomes more awake and lucid
B.

The patient becomes obtunded
C.

The patient has less trouble breathing
D.

The patient’s oxygen saturation goes from 92% to 97%

Correct Answer
B. The patient becomes obtunded

Explanation
If the patient becomes obtunded, it means they are experiencing a decreased level of consciousness or mental status. This could indicate a worsening condition and may require a different intervention or treatment approach. It is important to monitor the patient closely and adjust their treatment as needed to ensure their safety and well-being.

Which is true with regards to how CPAP helps improve a patient with CHF and pulmonary Edema?

A.

It helps to stent open alveoli
B.

It helps to alleviate bronchospasm
C.

It helps to improve lung compliance, which makes the work of breathing easier
D.

It is actually more effective than broncodilators, especially in an acute setting

Correct Answer
A. It helps to stent open alveoli

Explanation
CPAP stands for Continuous Positive Airway Pressure. It is a treatment method that delivers a constant level of air pressure to the lungs, helping to keep the airways open. In the context of CHF (Congestive Heart Failure) and pulmonary edema, CPAP helps to stent open alveoli. Alveoli are tiny air sacs in the lungs where the exchange of oxygen and carbon dioxide takes place. In conditions like CHF and pulmonary edema, these alveoli can become filled with fluid and collapse, making it difficult for the patient to breathe. CPAP helps to keep the alveoli open, allowing for better oxygenation and improved breathing.

When considering contraindications for applying CPAP, which is false?

A.

It should never be used in a patient with respiratory arrest
B.

It should not be used in an unconscious patient
C.

It should not be applied to patients with Hypertension
D.

It should not be applied to a patient with a Pneumothorax

Correct Answer
C. It should not be applied to patients with Hypertension

5.

Which of the following is not used to determine eligibility for CPAP?

A.

Respiratory rate > 25
B.

Severe dyspnea
C.

Abdominal distention
D.

Ability to follow commands

Correct Answer
C. Abdominal distention

Explanation
Abdominal distention is not used to determine eligibility for CPAP. CPAP (Continuous Positive Airway Pressure) is a treatment method used for individuals with sleep apnea or other respiratory conditions. It helps keep the airways open by providing a continuous flow of air pressure. The eligibility for CPAP is typically determined based on factors such as respiratory rate, severe dyspnea (difficulty breathing), and the ability to follow commands. Abdominal distention, which refers to the swelling or enlargement of the abdomen, is not directly related to the eligibility for CPAP.

Which is not one of the primary ways to treat an acute exacerbation of CHF with Pulmonary Edema?

A.

NTG
B.

CPAP
C.

Oxygen
D.

Trendelenburg Position

Correct Answer
D. Trendelenburg Position

Explanation
The Trendelenburg position is not one of the primary ways to treat an acute exacerbation of CHF with Pulmonary Edema. The Trendelenburg position is a position where the patient's feet are elevated higher than their head. This position is commonly used to increase blood flow to the brain and reduce the risk of aspiration during surgery, but it is not effective in treating pulmonary edema. The primary ways to treat an acute exacerbation of CHF with Pulmonary Edema include NTG (nitroglycerin) to reduce preload and afterload, CPAP (continuous positive airway pressure) to improve oxygenation and reduce work of breathing, and supplemental oxygen to improve oxygen levels in the blood.

Which is NOT a Contraindication of the King Airway

A.

Responsive patients with an intact gag reflex.
B.

Patients with known esophageal disease
C.

Patients who are more than 4 feet tall.
D.

Any patients that have ingested caustic substances

Correct Answer
C. Patients who are more than 4 feet tall.

Explanation
The King Airway is a type of supraglottic airway device used for securing the airway in emergency situations. It is contraindicated in patients with known esophageal disease, as it may increase the risk of regurgitation and aspiration. Responsive patients with an intact gag reflex can tolerate the placement of the King Airway. Patients who have ingested caustic substances may have injuries to the airway and should not have the King Airway inserted. The statement "Patients who are more than 4 feet tall" is not a contraindication for the King Airway, as height does not affect its use or effectiveness.

A patient who is 4' - 5' tall should use what size airway?

A.

Size 2
B.

Size 3
C.

Size 4
D.

Size 5

Correct Answer
B. Size 3

Explanation
A patient who is 4' - 5' tall should use a size 3 airway. The size of the airway is determined by the height of the patient. Size 3 is the most appropriate choice for a patient of this height range.

Choose the correct tube size for a patient who is 6' 4" tall.

A.

Size 2
B.

Size 3
C.

Size 4
D.

Size 5

Correct Answer
D. Size 5

Explanation
The correct tube size for a patient who is 6' 4" tall is Size 5. Tube size is typically determined by the patient's height, and Size 5 is the largest option provided. This size is likely necessary to accommodate the patient's height and ensure proper fit and functionality of the tube.
