If pCO2 is high, pH is

low (acidosis)

2

If pCO2 is low, pH is

high (alkalosis)

3

If HCO3 is high, pH is

high (alkalosis)

4

If HCO3 is low, pH is

low (acidosis)

5

pCO2 normal range

35-45 mmHg (respiratory)

6

pO2 normal range

80-100 mmHg

7

pH normal range

7.35-7.45 (metabolic)

8

HCO3 normal range

22-26

9

B-type natriuretic peptide (BNP) is

heart failure marker, released by an over-distention of the heart ventricles

10

B-type natriuretic peptide (BNP) - normal, critical ranges

500 - heart failure

11

Define PaO2

Pressure of arterial oxygen (mmHg)

12

Bariobariatrauma

nitrogen release by obese patients at altitude - preoxygenate with NRB for at least 15 minutes prior to lift-off

13

Three killers of vented patients during flight

tension pneumothorax pericardial tamponade hypovolemia

14

Define SaO2

Saturation of arterial oxygen (%)

15

Define SAO2

Saturation of alveolar oxygen (%)

16

Proper site for chest tube insertion is

4-5th ICS anterior axillary line

17

A patient in early shock will likely have what acid-base imbalance?

respiratory alkalosis (from hyperventillation)

18

Appropriate sites for NCD insertion are

2d ICS mid-clavicular line 4-5th ICS anterior axillary line 5-6th ICS mid-axillary line

19

Electrical alternans may be seen with

Pericardial tamponade (

20

The antidote for malignant hyperthermia is

Dantroline

21

Signs of malignant hyperthermia include

Tachycardia, muscle rigidity, rapid increase in ETCO2

22

What is Hamman's sign? What does it indicate?

Crunching sound heard with auscultation of anterior chest during heartbeats. Tracheobronchial injury

23

The first step to increase PaO2 is

Increase FiO2

24

Minute ventilation is

Respiratory Rate * Tidal Volume

25

High pressure vent alarms can be caused by __? What is the mnemonic?

D isplaced tube (Down, mainstem) O bstructed tube P neumothorax (Tension) E quipment failure S tacked breaths

26

Low pressure vent alarms can be caused by __?

Hypovolemia Displaced tube (extubated) Tubing Leaks Loose connections

27

Normal tidal volume is

6-10 mL/kg

28

Acute respiratory failure is defined as

PaO2 50mmHg

29

Adult ideal weight (for vent) is calculated as

Men = 50kg, Women = 45kg Above + (2.3kg / 1" over 60") ex: 69" Male = 70.7kg

30

A left shift in the oxyhemoglobin dissociation curve can be caused by?

Left = low

"L" in "alkalosis" (low H+)
