Oxygen therapy, cardiopulmonary resuscitation, euthanasia Flashcards
1
Q
Oxygen delivery is depending on ___
A
- Hb concentration -> anaemia
- PaO2 -> hypokalemia
- cardiac output
2
Q
In case of hypoxia PaO2 - ? Sa O2 -?
A
PaO2 < 80 Hgmm
SaO2 < 90%
Goal: increase the inspired O2 concentration (FiO2)
3
Q
Clinical signs of hypoxaemia
A
- restlessness
- dyspnoe
- increased respiratory rate (>32-40/min)
- labial breathing
- open mouth breathing (cats)
- abnormal respiratory sounds (upper airway stridor, crepitation
- cyanosis
- gasping
4
Q
Hypoxaemia <-> sedation ?
A
Sedatuion is necessary!
Acepromazine, butorphanol, midazolam
5
Q
Assessment of oxygenation
A
6
Q
“Flow by” oxygen
A
- small diameter tube held to the nose/nose canula
- through mask (some animals don’t tolerate)
- 2-3 litre/min -> FiO2: 25-40%
7
Q
Oxygen hood/collar
A
- Elisabeth collar ventral 50-75% covered by plastic folia
- 1 litter/10kg/min -> FiO2: 40-60%
- CAVE: some dogs dont tolerate it -> panting -> increased humidity -> hyperthermia
8
Q
Nasal oxygen catheter
A
9
Q
Oxygen cage
A
10
Q
Endotracheal intubation
A
11
Q
Mechanical ventilation - indications
A
- severe hypoxia (PO2<60mmHg)
- severe hypercapnia (PCO2>60mmHg)
- excessive work of breathing
12
Q
Cardiopulmonary resuscitation
A
RECOVER - reassessment campaign on vet resuscitation
13
Q
CPR. Warning sites
A
- changes in respiration
- weak, irregular pulse
- bradycardia
- hypotension
- cyanosis
- hypothermia
14
Q
CPR. Important consideration
A
- underlying disease
- owners will
- timing - within 3-5 minutes after CPA (cardiopulmonary arrest)
- equipment
- trained stuff (3+n)
15
Q
ABC of CPR
A
Basic life support:
Airways
Clean airways, endotracheal intubation
Breathing
AMBU-ballon + oxygen, 10/min, inspiration 1 sec, expiration 5 sec
Circulation
Advanced life support: Drugs, ECG, Fluids
