FCCS (Fundamentals of Critical Care Support) Exam-with
100% verified solutions-2023-2024
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 oxyge
