Q

Oxygenation

A

(Properly functioning alveolar capillary membrane.
Which oxygenates venous blood & removes carbon dioxide from blood)

Q

functional units of the respiration system

A

upper air way- warms filter and humidify
lower airway function- conduction of air, mucociliary clearance
alveolar capillary membrane- gas diffusion

14
Q

effects of decreased ventilation

A

gas exchange is decreased (less capillaries and lung volume)
ineffective cough
drier mucous membranes
risk for aspiration due to decreased gastric motility
impaired mobility
meds that decreased ventilation
tissues and airways get more rigid (diaphragm moves less efficiently which lead to less air exchange)

Q

rhonchi

A

secretions in large airway, course and discontinues sound, deep pitched

19
Q

diagnostic methods for pulmonary function

A

non invasive:
pulse ox
chest XR
Pulmonary function test

invasive:
arterial blood gas
bronchoscopy

20
Q

pulse ox

A

measure amount of hemoglobin saturated with oxygen
it uses arterial blood to measure

21
Q

Pulmonary function test

A

Assessment of breathing volumes

22
Q

ABG

A

ventilation
oxygen
pulse
PH
respiration

23
Q

to find the paO2 from the spO2

A

subtract 30 (unless it is 95% spO2 then is is 80% paO2)

24
Q

nursing interventions for pulmonary function

A

quit smoking
positioning
chest physiotherapy
pursed lip breathing
fluid intake 2L per day
good nutrition
medications
coughing and deep breathing
Incentive spirometry

25
Q

when to use cough suppressant

A

non productive cough

26
Q

when to use expectorants

A

productive cough

27
Q

bronchodilators

A

open narrowed airways

28
Q

corticosteroids

A

reduce inflammation in airways

29
Q

nebulizer

A

dispense fine particles of medication into deeper passage of the respiratory tract where it is absorbed

30
Q

Meter dose inhaler

A

delivers controlled dose of medication with each compression of the canister
