What is the single most important indicator in critical illness?
tachypnea
Beck's Triad
hypotension, JVD, muffled heart sounds
- a/w cardiac tamponade
What is the thyromental distance?
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
What does it mean when the thyromental space is < 3 fingerbreadths?
- approx 6 cm
- indicates the larynx might be more anterior and therefore difficult to visualize
during laryngoscopy
** a more acute angulation of the stylet at the distal end of the endotracheal tube
may be helpful.
Patient is apneic w/ a pulse. What do you do?
Bag them.
- One handed bag compressions should be delivered 10-20 times per min. Each
compression should take place over 1 second.
** If patient starts spontaneously breathing, try to be synchronous with their
respiratory efforts.
** If/once the patient is breathing easily and adequate Vt are being inhaled, enough
to produce minute ventilation, stop bagging.
What is the goal of manual mask ventilation?
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
_______
100% oxygen at a rate of 15L/min
HFNC
- 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
- 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
- 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
- minimum flow rate: 6L/min (to clear CO2 from mask)
- humidified O2
- Approx. concentrations L to FIO2 ratios:
6L = 40%
7L = 50%
8L = 60%
