Apnea Testing
What is the SBP prerequisite for performing the apnea test?
The patient's systolic blood pressure must be at least 100 mmHg
What is intra hospital transport?
Transport within the hospital
Describe the advantages of home mechanical ventilation related to human factors.
Improved quality of life and well-being, Patient and family self-sufficiency and sense of "wholeness", Maximizing patient comfort (especially towards end of life)
If an O2 flowmeter displays 7.5 LPM on a 70:30 Heliox mixture, what is the actual flow?
7.5 LPM x 1.6 = 12 LPM
What is considered a positive result for the apnea test?
No spontaneous respirations within the testing period and PaCO2 ≥ 60 mmHg or 20 mmHg increase
How many healthcare team members must accompany a critically ill patient?
A minimum of two people accompany a critically ill patient
Comprehensive discharge planning is not necessary for successful transition from hospital to home for ventilator-dependent patients?
False
What is the Recommended initial dose of NO?
Recommended initial dose is 20 ppm (particles per million
What is a criterion for determining brain death related to neural reflexes?
Absence of brainstem reflexes
What is the most common adverse event related to?
Equipment Failure is the most common
Evaluation and follow-up of home ventilation patients involves monitoring hospital readmissions, assessing equipment needs, and providing ongoing educational support to caregivers?
Yes
What is the half-life of NO?
very minimal half life (0.1 seconds – 5
seconds)
What is the recommended duration (in minutes) of an Apnea Test?
8-10 minutes
what is the partial pressure of O2 at 8000 ft atmospheric pressure?
Partial pressure of O2 is 118 mm Hg compared to 159 mm Hg at sea level
What is the first step to discharge planning of patient needing home MV?
There should be a strong desire on behalf of the patient and their family
What is a positive response of NO based-on hemodynamics and ABGs?
Increase in P/F ratio by 10% and/or PAP by 20% is a positive response.
what are 3 potential complications of the apnea test?
hypotension, cardiac arrhythmia, VFib
What can happen to tidal volume and ICP at high altitude levels?
•Ventilator Tidal volume is increased, may lead to lower PaCO2
•ICP can be significantly increased during ascent and descent
What is the general inclusion PEEP and FiO2 criteria for HMV?
FiO2 < .40 and PEEP < 10 cm H2O
How long will a full 80:20 Heliox “H” cylinder last if it is set to 12 LPM with an O2 flowmeter?
2200 psi x 2.50 / (1.8 x 12 LPM ) = 5500/21.6 = ~254.6 minutes or about 4 hrs, 24 min.
