When no ventilation is occurring, confirm with lung sounds

18
Q

In an asthma attack, when should you give duoneb?

They are hypoxic

21
Q

What is the treatment and cause for severe angioedema?

A

Benadryl (25-50 mg). Can be caused by adverse reaction to taking lesinopril

22
Q

What is the most serious issue of aspiration?

A

Will lead to ARDS

23
Q

What does mallampati stand for?

A

Indicates the difficulty of intubation of an airway. Class 1 is best option and class 4 is nearly impossible

24
Q

What is a potential issue with using the king airway?

A

Can decrease blood pressure to the brain due to pressure on the carotid

25
Q

What is asthma?

A

A chronic, triggered reactive lower airway disorder

26
Q
