Q

What is the function of the sinoatrial node

Q

What is the purpose of the AV node?

A

To provide a pathway for impulses from the atria to the ventricles.

It also creates a delay in conduction from the atria to the ventricles

Q

The purpose of the delay in conduction from the atria to the ventricles?

A
  1. This causes the atria to contract first, thus allowing the ventricles to fill with blood before they contract.
  2. Ensures proper timing so that the ventricles have time to fill completely before they contract and pump blood out to the tissues.

Q

What is happening in the heart during Diastole?

A

The atria and ventricles are relaxed.
De-oxygenated blood from the superior and inferior vena cava flows into the right atrium.
The open atrioventricular valve allow blood to pass through to the ventricles.

Q

What is happening in the heart during Atrial Systole?

A
  1. The SA node triggers both atria to contract.
  2. The right atrium empties blood into the right ventricle.
  3. The left atrium empties blood into he left ventricle.

Q

What is happening in the heart during ventricular systole?

A
  1. From the right ventricle, de-oxygenated blood is pumped into the pulmonary artery.
  2. The pulmonary valve prevents backflow into the right ventricle
  3. From the left ventricle, oxygenated blood is pumped into the aorta
  4. The aortic valve prevents the oxygenated blood from back flowing into the left ventricle.

46
What device is used most often to deliver oxygen
Nasal cannula
47
Simple mask is an oxygen mask for
Patients that need a moderate flow rate for a short time.
48
A simple mask has holes on the sides for?
Exhalation and air entrainment if the flow rate is too low.
49

51
Describe the oxygen mask attached to a tracheotomy tube
1. Exhalation port that remains patent at all times 2. A port that connects to the oxygen, with a large-bore tubing. 3. Requires humification
52
Negative-pressure ventilator
1. For home use | 2. Do no require an airfoils airway
53
Positive-pressure ventilators
1. More commonly used | 2. Requires an artificial airway
54
Chest tubes may be inserted through the?
Chest wall into the mediastinum or pleural space
55
Trocar
Is used to punch a hole in the chest wall through which the tube is inserted
56
In an emergent situation what 2 ways are chest tubes started?
Trocared or blunt dissection
57
If a chest tube tubing is long, it should no be allowed to?
Fall below the level of the patient’s chest.
58
In-dwelling catheters are usually inserted ....
Into the brachiocephalic vein at the junction of the superior vena cava, or directly into the superior vena cava.
