Q

fxn of Transmitter

A

sets respiratory rate and
length of inspiration (powered by battery)

–generates a coded
radiofrequency signal, so that it cannot be disrupted

Q

What are the controls of the transmitter?

A
  • On switch
  • RR control (# of pulse
    trainsmitted/min)
  • Insp Period (It )
  • Three controls for Vt
    …. Stimulus Amplitude
    … Pulse interval
    …. Pulse Width

Q

how to clean pacer

A

Autoclave electrodes and antenna/radio receiver
before implanting. Do not gas sterilize…ETO
residue or other chemicals can cause severe tissue
reaction

16
Q

wt are the bilevel device used ?

A

BIPAP(respironics), VPAP(resmed)

17
Q

what are te modes of BiPAP

A
  • CPAP
  • S
  • S/T
  • T
  • PC
18
Q

what are the therapy features of bipap

A
  • AVAPS
  • AVAPS rate
  • Bi-Flex٭
  • Ramp
  • Rise Time٭
  • Digital Auto-Trak
19
Q

external Battery of Bipap?

A

Up to 5 hours Power

20
Q

what are the main settings of Bipap

A
  • IPAP 4 to 40cmH2O
  • EPAP 4 to 25cmH2O
  • BPM 0 to 40
21
Q

what is the purpose of AVAPS

A

AVAPS will help patient maintain a VT equal

to or greater than the set VT

22
Q

how does AVAPS achieve its fxn

A

automatically controlling the PS provided to the patient

- by varying the IPAP level between the IPAP Min and IPAP Max settings (or PSmin and PSmax)

23
Q

Which mode is biflex available in

A

S mode

same as Cflex in CPAP

24
Q

indication of VPAP?

A

provide noninvasive ventilation due to respiratory

insufficiency or OSA patients >30 lbs

25
Q

fxn of vsync of VPAP

A

adjust the baseflow so that patient doesnt have to work as hard to trigger

26
Q

what does high, ed, low trigger and cycling mean

A

high–>easiest

low–>hardiest

27
Q

fxn of IBR

A

Intelligent Back Up Rate

it mimics patient breathing pattern in the background, when patient goes apneic, ventilator will provide breath similar to patient pattern

28
Q

What is IVAPS

A

Intelligent volume-assured pressured support

29
Q

indication for IVAPS

A

patient over 66ibs

30
Q

indication for stellar

A

provide ventilation for nondependent,
spontaneously breathing pt with
respiratory insufficiency, or respiratory failure,
with or without OSA

31
Q

what are some common alarms used in BIPAP, VPAP, stellar

A
  • Power failure
  • Apnea (not on VPAP3)
  • Low pressure
  • High pressure
  • Low volume
32
Q

how is fio2 affected in these machine

A

by flow and leak

33
Q

How are patient qualified for CPAP

A

documented sleep apnea – level 1
polysomnography

AND

significant symptoms/risks that are reversed with
treatment

34
Q

How are patient qualified for Auto-Titrating Positive Airway Pressure APAP

A

1.qualified for CPAP
AND
2.patients with prescribed fixed CPAP level of
10 cmH2O a minimum change of 4cmH2O between
REM and NREM

35
Q

What does the ADP funding package include for BIPAP, CPAP and APAP?

A

(i) a positive airway pressure device;
(ii) a heated humidifier;
(iii) a basic mask and headgear;
(iv) carrying case;
(v) 6 ft. tubing;
(vi) all necessary caps and filters,
(vii) user instruction manual

**patient dont have to pay out of the pocket for these components
