1
00:00:02,055 -->
00:00:07,021
Alright, so let's take a look at the bag valve mask a bit closer.
2
00:00:07,021 -->
00:00:11,055
Professional rescuers are encouraged to use the bag valve mask whenever possible
3
00:00:11,055 -->
00:00:14,066
but one important aspect of this is that it takes practice.
4
00:00:14,066 -->
00:00:17,016
It's not that it's rocket science at all,
5
00:00:17,016 -->
00:00:21,035
but it just takes practice to be able to get your fingers placed correctly
6
00:00:21,035 -->
00:00:25,017
and to get your own technique down with some of the hints I'm going to show you
7
00:00:25,017 -->
00:00:28,062
to be able to seal the mask to the face of the patient.
8
00:00:28,062 -->
00:00:31,029
Another mistake that's commonly made is we think
9
00:00:31,029 -->
00:00:34,057
we're going to crush the mask down onto the face of the patient.
10
00:00:34,057 -->
00:00:36,090
When in reality, we're sealing it,
11
00:00:36,090 -->
00:00:41,069
but bringing the face of the patient up into the mask.
12
00:00:41,069 -->
00:00:43,078
Not mask down on patient's face.
13
00:00:43,078 -->
00:00:46,052
Face up into mask.
14
00:00:46,052 -->
00:00:52,008
That combined with sealing with the C-E method
15
00:00:52,008 -->
00:00:54,071
allows us usually to get a pretty good seal.
16
00:00:54,071 -->
00:00:57,036
Some of the reasons you might not get a good seal
17
00:00:57,036 -->
00:01:02,070
is deformity to the face, traumatic injury to the face, or a lot of facial hair.
18
00:01:02,070 -->
00:01:05,026
If that happens, you're going to do the best you can,
19
00:01:05,026 -->
00:01:08,064
but it's probably going to be an intubation patient at that point
20
00:01:08,064 -->
00:01:10,031
to be able to control the airway.
21
00:01:10,031 -->
00:01:14,069
But for this case, we're talking about basic life support with a bag valve mask.
22
00:01:14,069 -->
00:01:17,031
Notice, I've taken the reservoir bag off.
23
00:01:17,031 -->
00:01:20,006
There is no oxygen hooked up to this bag.
24
00:01:20,006 -->
00:01:22,048
If there were oxygen hooked up to this,
25
00:01:22,048 -->
00:01:27,011
we would be at high flow oxygen delivery with bag expanded.
26
00:01:27,011 -->
00:01:31,095
The way you do that is cover the outlet while it's on high flow,
27
00:01:31,095 -->
00:01:34,003
the bag would expand and fill with air,
28
00:01:34,003 -->
00:01:36,023
and you're ready to start ventilating to capture
29
00:01:36,023 -->
00:01:38,080
as much of that percentage of oxygen as possible.
30
00:01:38,080 -->
00:01:43,020
But we're just going to do room air, which is perfectly acceptable as well.
31
00:01:43,020 -->
00:01:45,053
In fact, some statistics and studies are showing that
32
00:01:45,053 -->
00:01:48,018
it might be just great to do it with room air.
33
00:01:48,018 -->
00:01:53,052
Remember, too, the bag valve mask is helping this person
34
00:01:53,052 -->
00:01:56,003
who might possibly be in cardiac arrest
35
00:01:56,003 -->
00:02:00,027
because we're not giving them any percentage of our carbon dioxide
36
00:02:00,027 -->
00:02:03,009
thereby contributing to their hypercarbia
37
00:02:03,009 -->
00:02:06,013
and the CO2 buildup in their body.
38
00:02:06,013 -->
00:02:08,030
So there is a benefit of that.
39
00:02:08,030 -->
00:02:12,007
The other benefit is we're not putting our face anywhere near the person's face.
40
00:02:12,007 -->
00:02:15,016
Therefore, protecting ourselves from infection as well.
41
00:02:15,016 -->
00:02:18,000
So, when we put this on the patient's face,
42
00:02:18,000 -->
00:02:22,053
we're going to make sure that the narrow, pear-shape of this mask
43
00:02:22,053 -->
00:02:25,045
is going on the bridge of the nose.
44
00:02:25,045 -->
00:02:29,072
Then, the wider or broader part of the mask
45
00:02:29,072 -->
00:02:33,051
is going to cover below the lips and above the chin.
46
00:02:33,051 -->
00:02:37,003
Then, coming in at the stem with our fingers,
47
00:02:37,003 -->
00:02:39,003
our C, our thumb and first finger,
48
00:02:39,003 -->
00:02:42,016
we're sealing in this case the left side of the mask
49
00:02:42,016 -->
00:02:46,001
while the E, or the middle, ring, and pinky fingers,
50
00:02:46,001 -->
00:02:49,036
grab the mandible, or the jaw of the patient,
51
00:02:49,036 -->
00:02:51,099
and again, this is after we have gone ahead and
52
00:02:51,099 -->
00:02:55,002
put the person's head in a good head-tilt, chin-lift position
53
00:02:55,002 -->
00:02:57,075
and we're drawing the face up into the mask.
54
00:02:57,075 -->
00:03:01,076
Now slowly, over a second, we're delivering a good rescue breath.
55
00:03:02,066 -->
00:03:04,053
Letting them exhale.
56
00:03:04,053 -->
00:03:07,053
Delivering another slow rescue breath.
57
00:03:07,053 -->
00:03:10,088
Looking for chest rise and fall.
58
00:03:10,088 -->
00:03:16,095
It's very easy to lose track of how fast you're ventilating
59
00:03:16,095 -->
00:03:20,002
the patient when you're using a bag valve mask.
60
00:03:20,002 -->
00:03:24,003
And there has been some statistics showing that we're actually
61
00:03:24,003 -->
00:03:26,058
hyperventilating patients that do not need to be hyperventilated.
62
00:03:26,058 -->
00:03:31,078
Remember, it's one breath over a second delivery is ideal.
63
00:03:31,078 -->
00:03:34,043
And for people that just need rescue breathing,
64
00:03:34,043 -->
00:03:36,013
we're trying to breathe for them about the average that
65
00:03:36,013 -->
00:03:38,095
a real, living, human being would need to be breathed for.
66
00:03:38,095 -->
00:03:42,007
One breath every 5 to 6 seconds and about 12 a minute.
67
00:03:42,007 -->
00:03:44,009
So we're not hyperventilating the patient
68
00:03:44,009 -->
00:03:46,088
unless the protocol is calling for hyperventilation
69
00:03:46,088 -->
00:03:48,026
then follow that protocol.
70
00:03:48,026 -->
00:03:52,016
So, I hope this was helpful for the bag valve mask.
71
00:03:52,016 -->
00:03:54,083
Practice makes perfect. Keep that in mind.
72
00:03:54,083 -->
00:03:57,011
And the more you can practice, the better.
