What is the most commonly seen shock?
What causes hypovolemic shock?
What are the elements of the history gathered in cases of shock?
P - Past medical histroy
L- Lasts (last meal, last BM, last urination)
What are the components of an initial assesment in cases of shock?
Level of conciousness
What is the first phase of shock?
What is the second phase of shock?
What symptoms are associated with hyperdynamic shock?
Tachycardia, tachypnea, brick red m.m., rapid CRT, bounding pulse
What symptoms are associated with hypodynamic shock?
Weak abnormal pulses, pale and prolonged mm, hypothermia, weakness, depression, loss of conciousness
Cats in septic shock present with what?
What are the components of shock treatment?
What are some signs of impending collapse?
Poor perfusion (prolonged CRT)
Irregular/absent heart sounds
Abnormal breathing patterns / Apnea
Fixed and dilated pupils
What two organs are we most concerned with in Basic Life Support situations?
Heart and Brain
What is the "CAB" of resuscitation?
How do you perform CPR on small dogs/cats?
1. Use direct compression
2. Right lateral recumbency, squeeze thorax and compress chest wall 1/2 - 1/3 inch with a rate of 100 per minute
3. Artificial ventilations should be given at a rate of 10 breaths per minute (1 breath per 6 compressions)
If administering CRP alone what is the process?
Do 30 compressions followed by 2 breaths, mouth to snout.
What breed of dogs must be in dorsal recumbency for CPR?
What is the depth of compression to be used for average size dogs?
What is the compression to breath ratio for large breed dogs?
What are interposed abdominal compressions?
When the abdomen is compressed during the recoil phase of chest compressions
Enhances venous return to the heart
What complications are associated with interposed abdominal compressions?
Organ contusions (liver)
What are the signs of partial obstruction?
Difficulty breathing on inspiration
What are the signs of total airway obstruction?
No airway sounds
Chest does not move or expand
If no spontaneous respirations are occurring what should be done?
Administer 100% oxygen to patient
What 3 conditions require immediate attention?
Severe bleeding - catastrophic hemorrhaging
Failure to achieve effective ventilation may lead to acidosis and hypoxemia which may then lead to:
Under hypoxemia and acidosis which muscles function poorly?
Cardiac and vascular smooth muscles
