Q

Describe the suppression of the ventilatory drive

A

When the Bicarbonate sensors in the brain change to dectect for oxygen, if you give a patient too much O2 they can forget to breathe.

Q

Describe absorption ateletasis

A

Loss of lung volume causes by the resorption of air within the alveoli. There is no nitrogen to hol the shape of the alveoli.

Q

What is the difference between respiration and ventilation

A

Respiratory is the gas excahnge that happens between the alveloli and the capillaries. Ventillation- air moving in and out of the body

A

Giving babies above 80 torr of of oxygen.

23
Q

Low flow FiO2 range

A

0.22 to 0.80

24
Q

High Flow FiO2 range

A

0.24- 0.1

25
Q

What is a low flow nasal cannula.

A

A clear tube that delivers low flow oxygen through the nares.

26
Q

At what flow on nasal cannulas should we add a humidifier

A

4L Per minute or when the patient asks.

27
Q

What is the FiO2 range for a nasal cannula

A

0.24-0.44 delivers oxygen 1-6 L per minute.

28
Q

What conditions afftec t the FiO2

A

Respiratory rate, tidal volume and oxygen flow rate.

29
Q

What is a TTO

A

Transtracheal oxygen catheters.

30
Q

Pulse demand oxygen delivery system

A

Patient takes a breathe and the oxygen pulses and flows into the tubes.

31
Q

What are 3 examples of Oxygen conserving devices?

A

Transtracheal oxygen catherers, Reservoir cannulas, Pulse demand oxygen delivery systems

32
Q

How much oxygen can the resovior mustache cannula hold?

A

20ml or cc

33
Q

How much oxygen can the resovoir pendant cannula?

A

can hold 40 ml of cc

34
Q

How much Liters of xygen can a Pulse Demand Oxygen Delivery System deliver.

A

1 to 5 L per minute.

35
Q

Simple Oxygen Mask

A

A low flow device that delivers FiO2 of 0.35 to 0.50 at flows of 5 to 10 L min. It also has a reservoir inside the mask.

36
Q

Partial Rebreathing Mask

A

Resrvoir bag but has no valves, Delivers FiO2 of 0.40 to 0.60 at flows of 6 to 8L/min. Bag must be one-third to one hald full during inspiration.

37
Q

What is a Nonrebreathing Mask.

A

Has two valves attached to the mask. Valves allow patient to pull oxygen from resovior during inspriation. FiO2 range is 0.60 to 0.80

38
Q

What is the other name for Venti Masks?

A

Air Entrapment Masks

39
Q

What is the primary use of air entrapment masks?

A

To provide oxygen therapy for COPD Paitents.

40
Q

What is the flow range for Air Entrapment or Venti Mask?

A

2 TO 10 L per minute

41
Q

What is an oxygen hood used for?

A

Used to deliver supplemental oxygen to infants, can be nosiy

42
Q

Incubators

A

Regualte the temperature, humidity and FiO2 of an infants environment.

43
Q

What is the FiO2 percentage when the port is open and when it is closed?

A

Open 0.40 or less
Closed 0.40 or higher

44
Q

Hyperbaric oxygen therapy

A

exposes patients to pressure greater than atmospheric pressure while they breathe 100% oxygen. Can be done continuously or intermittently.

45
Q

Nitric oxide

A

Pulmonary vasodilator used to treat persistent pulmonary hypertension in New borns

46
Q

Heliox therapy

A

Helium is a lighter gas that attaches to oxygen . Makes it easier for oxygen to move through airways that are obstructed. Eg asthmatics.

47
Q

What is the FiO2 for venti mask.

A

24 to 100%

48
Q

What is the flow rate for high flow nasal cannula in L per minute

A

1L to 60L perminute

What is the FiO2 for High flow nasal cannulas

A

21-100%

50
Q

What is P-E-E-P

A

Positive end expirtratory pressure - Resiudal volume.
