Q

CPCR

CABDE

A

Cardiopulmonary Cerebrovascular Resuscitation

Bag patient every 10-12 seconds

Pump chest at 100 bpm until ROSC (return of spontaneous circulation)

CABDE

Circulation - most important

Airway

Breathing

Drugs

ECG

2
Q

CPR

A
  • Cardiac arrest (absent QRS)
  • No corneal reflex (last reflex to go)
  • No heart beat

Respiratory arrest leads to cardiac arrest

3
Q

Types of Emergencies due Equipment failure

A
  • CO2 absorbent exhaustion
  • Empty oxygen tank
  • ET blockage
  • incorrect assembly of anesthetic machine
  • Vaporizer issues
  • Pop-off valve issues
4
Q

Drugs used cardiac arrest

A
  • Epinephrine or Vasopressin for cardiac arrest
  • Atropine if anesthesia related cardiac arrest
  • Dopamine to increase force and rate of cardiac contraction
5
Q

Cable placement

A

Right Left

White Black

Green Red

Use alcohol

Shave

ECG is well grounded

Place patient on rubber mat

place leads on elbow and stifle region

7
Q

PQRST

A

P: Depolarization of atria

  • Atrial dysfunction
  • heart block degree

QRS: Depolarization of ventricle

  • Ventricular fibrillation
  • Premature Ventricular contraction
  • heart block degree

T: Repolarization of ventricle

  • Mycardial hypoxia
  • electrolyte disturbances

PR Interval: delay in AV node depolarization due to blood filling ventricles. (no waves produced)

8
Q

Types of Interference

A

9
Q

Atrial Premature Contraction

Ectopic P wave

i.e. P wave immediately follows T wave

A

10
Q

Ventricular Premature Contraction

QRS wave is either positive or negative

A

11
Q

Tachycardia

Normal Sinus rhythm

> 160bpm (Dogs)

>240 bpm (Cats)

Drug Causes: ketamine, atropine, epinephrine

Surgical Stimulation

A

12
Q

Ventricular Tachycardia

3+ ectopic ventricular complex

140 bpm

A

13
Q

Atrial Flutter

multiple P waves

saw tooth shaped wavelength

A

14
Q

Sinus Bradycardia

Normal sinus rhythm

A

15
Q

Atrial Fibrillation

Lacks P wave

A

16
Q

Ventricular Fibrillation

Lacks QRS wave

Will lead to cardiac arrest

A

17
Q

1st degree Heart Block

long P wave

A

18
Q

2nd degree heart block

P wave sometimes not followed by QRS

Lowers ability to fully contract

Causes: Alpha 2 Agonist, Hyperkalemia, heart disease

A

19
Q

3rd degree heart block

Irregular P and QRS Wave

Lowers ability to fully contract

Causes: Alpha 2 Agonist, Hyperkalemia, heart disease

A

20
Q

ECG Readings

A

50mm/sec - read 3 secs and multiply by 20

25mm/sec - read 6secs and multiply by 10
