Answer 2

HR in min

Question 3

Total sleep time

Answer 3

Sleep onset (N1) to the last epoch of sleep

Question 4

Total Recording time

Answer 4

lights out to lights on in min = Total Recording time

Question 5

Sleep Latency

Answer 5

Lights out to the first epoch of any sleep in min

Question 6

Stage R Latency

Answer 6

Sleep onset to the first epoch of Stage R in min

Question 7

Wake after sleep onset

Answer 7

Total Recording time - Sleep Latency - Total Sleep time

Question 8

What is the formula Sleep efficiency?

Answer 8

Total Sleep Time / Total Recording time X 100

Question 9

Total sleep time in each stage

Answer 9

Time in each stage / Total Sleep time X 100

Question 10

What is the formula for the arousal index?

Answer 10

Number of arousals X 60/TST = ArL index (in Min)

Question 11

What is the formula for the PLMS index?

Answer 11

PLMS x 60/TST = PLMS index (in Min)

Question 12

What is the formula for the PLMS arousal index?

Answer 12

PLMS with arousals x 60/TST = PLMS arousal index

Question 13

What is the formula for the apnea index?

Answer 13

(# of obstructive apneas + # of central apneas + # of mixed apneas) x 60/TST = the apnea index

Question 14

What is the formula for the Hypopnea index?

Answer 14

Hypopneas x 60/TST = Hypopnea index

Question 15

What is the formula for the Apnea + Hypopnea index?

Answer 15

of apneas and hypopneas x 60/TST = the apnea + Hypopnea index

Question 16

What is the formula for the obstructive apnea hypopnea index?

Answer 16

(# of obstructive apneas + # of mixed apneas + # of obstructive hypopneas) x 60/TST

Question 17

What is the formula for the central apnea hypopnea index?

Answer 17

(# of central apneas + # central hypopneas) x 60/TST = central apnea hypopnea index

Question 18

What is the formula for the Respiratory Effort-Related Arousal index?

Answer 18

of RERAs x 60/TST = Respiratory effort-related arousal index

Question 19

What is the formula for the Respiratory disturbance

index?

Answer 19

AHI + RERA index = RDI
