18
Q

What happens when gas is exchanged?

A

 02 moves from the lungs to the bloodstream CO2 passes from the blood to the lungs

19
Q

 What is at the end of each bronchiole and what does it do?

A

Alveoli where the lungs in the blood exchange 02+ CO2

20
Q

 How many times does this happen per minute? Respiratory rate.

A

12 to 20 is the normal rate

21
Q

Inspiration

A

 Air is drawn in and chest cavity expands

22
Q

Expiration

A

Air moves out and chest cavity become smaller

23
Q

If a patient cannot ventilate on their own, what do you do?

A

Bag valve mask

24
Q

What may cause a patient to stop breathing?

A

Medication overdose
 Spinal cord injury
 Anesthesia

25
Q

How often should you bag valve mask pump?

A

Once every five seconds or 12 to 20 times per minute

26
Q

Oxygenation who should you see first?

A

 Apneic or obstructed patient

27
Q

What does surfactant do?

A


Surfactant increases compliance in the lungs

28
Q

85 to 95% 02 what do we do?

A

 Apply a nasal cannula begin at 2 L a minute increase to 6 L a minute

29
Q

80 to 85% 02. What do we do?

A

Apply a Venturi mask 4 to 6 L a minute anything over 4 L will dry out

30
Q

Less than 80% 02 what do we do?

A

 Apply a non-rebreather at 10 to 15 L per minute

31
Q

A person is apneic. What do we do?

A

Apply a bag valve mask


32
Q

When do you use humidification?

A

Giving oxygen greater than 4 L a minute and infants always need humidification

33
Q

Wheezing

A

Cause – airway narrowing, or bronchoconstriction
Sound – whistling

34
Q

Stridor

A

Causes – airway obstruction
 Tracheal inflammation
 Sound – wheezing in upper airway

35
Q

Crackles

A

Sound – rice, crispy treats
 Causes – fluid in lungs

36
Q

Broncovesicular

A

Sound – normal breathing sound

37
Q

Oxygenation – diagnostic test

A

ABG - tells how much CO2 + O2 in the blood

Chest X-ray - non-invasive want to make sure lungs are clear

38
Q

Oxygenation – prevention

A

 Education
– Hand hygiene
– Stop smoking
– Vaccination
– Deep breathing
– Coughing

39
Q

Oxygenation – secondary – screening

A

– Auscultating lung sounds
– CT scan

40
Q

Oxygenation - Tertiary - Treatment

A

– Positioning
– Medication
– Administering 02
 - nutrition

41
Q

Oxygenation – poor ventilation

A

– Give breaths
 Adult – 12 to 20 breaths
 Baby – 30 to 60 breaths

42
Q

Oxygenation – education

A

Incentive spirometer – prevent adelecticis
Pursed lip breathing – exhale CO2
 Cough and deep breathing

43
Q

What is cellular regulation?

A

Functions within a cell to maintain homeostasis in the way it produces an intracellular response, including horror, moans, Cito, Keynes, and neurotransmitters.
