What is the goal of manual mask ventilation? - Answer-to
provide adequate minute ventilation: the product of the
tidal volume delivered during each resuscitation bag
compression and the number of compressions per min.
** The total gas volume within most adult resus bags is 1
to 1.5 LITERS
Bag mask should be connected to ________% oxygen
and flow at a rate of _______ - Answer-100% oxygen at a
rate of 15L/min
HFNC - Answer-- Uses up to 100% oxygen source
- Provides higher amounts of FIO2 (0.32-1.0) in patients
with high minute ventilation requirements by matching
patient's inspiratory demands and minimizing air dilution

- These devices also can generate PEEP (that is difficult to
measure; can cause barotrauma in theory)
- Flow rates up to 60L/min
- heated and humidified oxygen
NRB - Answer-- AKA Reservoir Face Mask
- Bag is filled with 100% oxygen from a supply source
(tank)
- The flow rate must be adjusted so that the bag remains
completely or partially distended throughout the
respiratory cycle
- When the mask is properly applied, oxygen delivery can
be maximized but rarely exceeds a FIO2 of 0.6 to 0.9
- One way flap valves minimize entrapment of room air
which dilutes FiO2
- NRB is a high oxygen high, flow device.
- non humidified oxygen
** commonly used to improve oxygenation in patients with
severe hypoxemia until further eval and treatments are
accomplished.

Aerosol Face Mask - Answer-- This mask has large side
holes, the mask itself is attached to large bore tubing to a
nebulize that blends 100% oxygen and room air to deliver
a PRESET FIO2 level (done by dial on oxygen adapter)
- If the entire aerosol mist disappears from the mask
during. inhalation, the patient's inspiratory flow demands
are probably exceeding the capacity of the nebulizer and
room air is being entrained.
- minimum flow rate = 8L/min
- Max FIO2 = 40-60%
- This is a variable oxygen, moderate-flow device.
Simple Face Mask - Answer-- minimum flow rate: 6L/min
(to clear CO2 from mask)
- humidified O2
- Approx. concentrations L to FIO2 ratios:
6L = 40%
7L = 50%
8L = 60%

Venturi Face Mask - Answer-- aka air entrainment face
mask
- delivers O2 through a jet mixing device that increases
the velocity of oxygen and causes a controlled
entrainment
- the FiO2 can be more precisely controlled from .24 to .5
(24% to 50%) at high flow rates simply my selecting the
interchangeable nozzle and adjusting the O2 flow rate
- this is a high flow, controlled oxygen device.
What is the single most important indicator in critical
illness? - Answer-tachypnea
Beck's Triad - Answer-hypotension, JVD, muffled heart
sounds
- a/w cardiac tamponade
What is the thyromental distance? - Answer-It is the
distance in finger breadths between the anterior
prominence of the thyroid cartilage (adam's apple) and the
tip of the mandible (chin). It is an estimate of the length of
the mandible and the available space anterior to the larynx
