[respiratory failure]: give 3 signs of chronic hypoxia
polycythaemia
cor pulmonale
pulmonary hypertension
26
[respiratory failure]: give 7 signs of hypercapnia
```
peripheral vasodilation
headache
bounding pulse
tachycardia
co2 retention flap
confusion
papilloedema
```
27
[respiratory failure]: when would you consider doing a sputum culture
if febrile
28
[respiratory failure]: what SpO2 defines hypoxia
29
[respiratory failure]: in which type of respiratory failure may O2 delivery be dangerous
type 2
30
[respiratory failure]: why is O2 delivery in hypoventilation dangerous
insensitive to CO2
respiration driven by hypoxia
lack of respiratory drive
31
[respiratory failure]: why is O2 delivery in hypoventilation dangerous
insensitive to CO2
respiration driven by hypoxia
lack of respiratory drive
32
[respiratory failure]: 1st line Tx in type 1
60% O2 mask
33
[respiratory failure]: 1st line Txs in type 2 (2)
controlled 24% O2 therapy
treat underlying cause
34
[respiratory failure]: 1st line Txs in type 2 (2)
controlled 24% O2 therapy
treat underlying cause
35
[respiratory failure]: why might there be an increased build up of CO2 even after O2 delivery in type 2
hypoventilation results in an inability to excrete CO2
36
[respiratory failure]: how soon should you check ABGs during Tx of type 2 respiratory failure
every 20 mins
37
[respiratory failure]: what are the indications for assisted ventilation in type 2 failure (2)
a rise in CO2 of >=1.5kPa following 24 % O2 therapy
| still hypoxic
38
[respiratory failure]: what are the indications for increasing O2 therapy from 24% to 28% in type 2 respiratory failure
CO2 steady or lower
39
[respiratory failure]: what are the indications for increasing O2 therapy from 24% to 28% in type 2 respiratory failure
CO2 steady or lower
40
[respiratory failure]: what O2 sat should you aim for in type 1 failure
94-98%
41
[respiratory failure]: what O2 sat should you aim for in type 2 (or whenever hypercapnia is a danger)
88-92%
42
[respiratory failure]: which mask type is the most accurate at high flow rates up to 60%
venturi
43
[respiratory failure]: which mask type allows for accurate delivery of O2 up to 90%
non-rebreathe
44
[respiratory failure]: which mask type allows for accurate delivery of O2 up to 90%
non-rebreathe
45
[respiratory failure]: what is the indication for assisted ventilation in type 1 RF
