5 Common Respiratory Emergencies Free Online FlashCards

Why can a silent chest be a dangerous sign?

A silent chest, weak respiratory effort, or reduced consciousness can signal impending respiratory failure, not improvement.

What should you do first when respiratory distress is severe or worsening?

Get help early for severe or worsening distress, and do not leave the person alone.

What important information does pulse oximetry not provide?

Pulse oximetry does not assess ventilation or carbon dioxide retention.

What is the general oxygen saturation target for adults with acute asthma?

For adults with acute asthma, the general target is 92–95%, subject to clinical guidance and individual prescribed targets.

What is a key initial treatment for an asthma exacerbation?

Give an inhaled rapid-acting bronchodilator according to the patient’s action plan or local protocol; a metered-dose inhaler with spacer is often suitable.

When is epinephrine indicated alongside asthma symptoms?

Epinephrine is not routine treatment for an asthma attack without anaphylaxis; give it promptly if asthma occurs with suspected anaphylaxis.

How is a COPD exacerbation generally recognized?

A COPD exacerbation is a sustained worsening beyond usual day-to-day variation, often involving increased breathlessness, cough, sputum volume, or sputum purulence.

Name two urgent conditions to consider besides COPD exacerbation in worsening breathlessness.

Consider pneumonia, heart failure, pulmonary embolism, or pneumothorax as other urgent causes of breathlessness.

Must anaphylaxis include skin signs?

Skin signs such as hives, flushing, or swelling are common but may be absent.

What medicine must be given promptly for suspected anaphylaxis?

Give intramuscular epinephrine promptly according to the prescribed autoinjector instructions or local protocol. Antihistamines do not replace it or justify delaying it.

How should a person with suspected anaphylaxis be positioned?

Keep the person lying flat where possible; allow a position of comfort if breathing is difficult, and do not let them stand or walk.

What does inspiratory stridor suggest, and when is it especially urgent?

Inspiratory stridor is noisy breathing that can signal upper-airway obstruction; stridor at rest or rapidly worsening symptoms require emergency help.
