ET CO2 Flashcards
1
Q
Normal ET Co2
A
3.5-5kPa
2
Q
Information from capnograph
A
EtCo2 measurement
Respiratory rate
Information from waveform
3
Q
Information from ETCo2
A
Confirms patency of airway and ET tube placement Indication of CO Detects rebreathing Detects air and fat embolism Ensures normocarbia
4
Q
Factors causing low ETCo2
A
Disconnecte/blocked ET tube Inadvertent extubation Oesphageal intubation Hyperventilation Hypthermia Hypovolaemia Pulmonary embolism Drop in CO Cardiac arrest
5
Q
Factors causing ETco2 above %kPa
A
Hypoventilation Hyperthermia Malignant Hyperthermia Sepis Increased skeletal muscle activity Rebreathing/obstructed airways Exhausted soda lime Co2 retention due to depressed respiratory centre, lung dysfunction, weakened respiratory muscles
6
Q
Normal Arterial CO2
A
4.8 -6 kPa
