Q

What is the pathology of a third degree or complete AV block?

A

Impulse originating in the SA node is completely blocked. It can happen either at the AV node, bundle of His or bundle branches. In response, the heart may develop a secondary pacemaker in order to stimulate the ventricles to contract. The location of this “escape pacemaker” will determine if the QRS complexes are wide or narrow

Q

What is the characteristic of a supraventricular tachycardia on an EKG?

A

Narrow QRS complexes

51
Q

Is supraventricular tachycardia the name of a specific arrhythmia?

A

It is used to describe a category of regular arrhythmias that cannot be identified more accurately because they have indistinguishable P waves due to their very fast rate, usually greater than 150bpm

52
Q

A

SA node and AV nodes

53
Q

What is the name of an atrial tachycardia that suddenly arrises from a very irritable automaticity focus?

A

Paroxysmal supraventricular tachycardia

54
Q

What is multifocal atrial tachycardia?

A

chaotic and irregular rhythm due to multiple foci, each with their own rates, stimulating the atria

55
Q

What is juntional tachycardia?

A

the AV junctoin becomes irritable and begins firing rapidly leading to a very rapid heart rate

56
Q

what does the EKG look like for a patient with junctional tachycardia?

A

If P waves are present, they would be inverted. The reason that P waves are inverted in junctional rhythms is because the impulse is being conducted backwards through the atria.

57
Q

What is atrial fibrillation?

A

Blood pools in the heart where a blood clot can form.

58
Q

What is the rate of AF?

A

400-600 impulses per minute triggered by the AV node.

59
Q

What medication can you give the patient if they are experiencing atrial fibrillation/

A

calcium channel blockers

60
Q

What is an atrial flutter?

A

impulse circles around a large area of atrial tissue create multiple P waves

61
Q

How do you determine whether or not the rhythm is regular if the patient has atrial flutter

A

If the AV nodes blocking the rapid impulses coming to it fires at a regular rate

62
Q

When is the rhythm irregular if a patient has Atrial Flutter?

A

If the AV node blocks the rapid impulses coming to it at an irregular rate

63
Q

What is ventricular tachycardia?

A

When an irritable automaticity focus on either ventricle begins firing. It overridesthe higher pacemaker sites and takes control of the heart. Ventricles begin firing prematurely and at an abnormal manner.

64
Q

What does the EKG look like if a patient has Ventricular Tachycardia?

A

QRS complex is wide

65
Q

What is monomorphic ventricular tachycardia?

A

when the QRS complexes are of the same shape and amplitude.

66
Q

What is polymorphic ventricular tachycardia?

A

When QRS complexes are of different shape and amplitude.

67
Q

How do we treat polymorphic ventricular tachycardia?

A

The same as VF= defibrillation

68
Q

What does torsades de pointes look like on an EKG?

A

When the QRS complexes are of different shape and amplitude.

69
Q

What causes torsades de pointes?

A

low potassium or quinidine toxicity

70
Q

What is the treatment for torsades de pointes?

A

magnesium

71
Q

What is one of the earliest signs of MI on an EKG?

A

When there is ST elevation

72
Q

How do you determine if there is an ST elevation?

A

Use an isoelectric line that goes rom the beginning to the endof the QRS complex. If the line is level, then it is normal, but if hte ST segment exists the complex prior to returning to the isoelectric line, then the ST segment is elevated

73
Q

If an MI is mild, does that mean that the ST segment has to be elevated?

A

No, an ST elevation does not need to happen if mI has occurred.

74
Q

What can indicate ischemia on an EKG?

A

Inversion of the T wave

75
Q

What is the compression to ventilation ratio?

A

30:2

76
Q

77
Q

What should the depth of a compression be?

A

2 inches

78
Q

If there are two people present, what is the rotation time limit?

A

2 minutes to prevent fatigue and improve quality of chest compressions

79
Q

What happens if after 30 compressions, patient is not breathing effectively?

A

head tilt-chin to open the airway when there is NO suspected cervical spine injury

80
Q

If you need the cervical spine to be immobilzied, what can you do instead of the usual technique?

A

jaw-thrust with cervical spine immobilization. Do not tilk the head or the neck if neck injury is expected.

A

2 breaths, with a bag valve mask (2 people) or a face mask (1 person)

82
Q

1 breath ever 5-6 seconds (10-12 breaths perminute)

84
Q

What is the best way to relieve severe choking in a responsible adult or child?

A

abdominal thrust

85
Q

When should you use a nasopharyngeal airway?

A

use in a semi-conscious person, selecting the appropriate size by comparing the outer circumference of the nPA with the inner aperture of the nares, the length should be determined by measuring from nose tip to the earlob

86
Q

When should you use the oral pharyngeal airway?

A

use in an unconscious person with no gag reflex, select the appropriate size by placing the tip of the OPA at the corner of the mouth and then the flange should be at the angle of the mandible

87

A

if the provider is inexperienced with ETT

88
Q

When should you use a king airway or combitube?

89
Q

What is the preferred airway to ensure that it is adequate an dprotected?

A

endotracheal tube

90
Q

How do you placed an endotracheal tube?

A

using a laryngoscope, or fiber optic device, looking for the triangular vocal cords, and placing the ETT through them .

91
Q

How long should an attempt be for endotracheal tube?

A

30 seconds

92
Q

when should you insert the advanced airway?

A

How do you confirm E.T. Tube placement?

A
  • Chest rise
