1. What is the single most important indicator in critical illness?: tachypnea
2. Beck's Triad: hypotension, JVD, muffled heart sounds
- a/w cardiac tamponade
3. 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
4. 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.
5. 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 adequateVt are being inhaled, enough
to produce minute ventilation, stop bagging.
6. 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
7. Bag mask should be connected to % oxygen and flow at a rate
of : 100% oxygen at a rate of 15L/min
8. 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)

Fijne website voor elke student die hulp nodig heeft bij het leren.
Nadat ik Knoowy ontdekt heb, ga ik regelmatig op zoek naar eventuele bruikbare samenvattingen! Heel erg handig!
Soms koop ik meerdere samenvattingen over 1 boek. Dit helpt mij als ik onvoldoende tijd heb om het hele boek te lezen en zelf geen samenvatting kan maken.
Het is de moeite om hier samenvattingen te kopen als je zelf onvoldoende tijd hebt ervoor.
Super hulp bij het studeren en bespaart veel kostbare tijd.
Een echte aanrader! Je vindt er heel wat nuttige samenvattingen!
Knoowy is een goede website. Het heeft veel aanbod en het werkt fijn.
Het uploaden en verkopen van mijn documenten verloopt altijd super vlot, alles word eigenlijk al door Knoowy geregeld! Leuk dat medestudenten ook iets aan mijn documenten hebben!
