“The traditional flowmeter is a calibrated tapered glass tube in which a bobbin or a ball float is used to indicate the flow of gas. Flowmeters with a ball float should be read in the middle of the ball. Meters with a bobbin should be read at the top of the bobbin”

• TRUE

• FALSE

obat yang dapat digunakan untuk terapi atrial fibrilasi, KECUALI:

• propanolol

• esmolol

• amiodaron

• epinefrin

treatment of hypotension intraoperatively:

• Decreasing anesthetic depth

• volume depletion

• increase PEEP

• relieving obstruction of vena cava superior

Etiology of Hypertension intraoperative:

• deep anesthesia

• endobronchial intubation

• bladder distention

• rebound steroid

The pressure regulators divide the machine into low pressure (proximal to the regulator) and high pressure (distal to regulator) system

• TRUE

• FALSE

hypoxemia occurs when oxygen delivery to the tissues is insufficient to meet metabolic demand, because:

• lower airway obstruction

• large leaks in the anesthesia machine

• acute respiratory infection

• transfusion therapy

Adequate brain relaxation is achieved by:

• adequate ventilation PaCO2 45-55 mmHg

• adequate oxygenation PaO2 80-100 mmHg

• Adequate cardiac contractility

• prevent hipoxemia

These sentence is correct about CVP, EXCEPT:

• normal CVP 2-6 mmHg

• pressure is monitored as the level of the vena cava or the left atrium

• decreased CVP is due to decreased intravascular volume or venous return

• at low levels of PEEP, the CVP increases with increased PEEP

posterior fossa surgery:

• may cause damage in respiratory centers

• sudden tachycardia occurs if the trigeminal nerve is stimulated

• increase gag reflex

• reduce risk of aspiration

about venous air embolism:

• increase risk in lateral position

• dopller ultrasound is the best methode to detect VAE

• sudden increase in etCO2

• hypertension
