Q

At what pressure will many tanks stop working?

A

Many tanks will not work at pressure below 200 psi

Therefore, the residual amount of oxygen of any tank is 200 psi.

27
Fill in the blank: Time to empty = [amount in tank (psi) – residual (200 psi)] x ______.
tank constant
28
How long can you administer oxygen at 15 L/min with a D tank at 1800 psi?
17 minutes
29
What is the rationale behind understanding PEEP for intubated patients?
To optimally treat pulmonary edema by knowing how PEEP works and integrating its application into patient care.
30
What are the two components of the training plan for the PEEP MCP Skill Module?
* Online self-directed study session * Face-to-face collaborative learning session
31
What is the target audience for the PEEP MCP Skill Module?
Emergency Medical Services employees registered as Advanced Care Paramedics (ACP) with the Alberta College of Paramedics.
32
What is the goal of PEEP?
To improve oxygenation and reduce FiO2 while minimizing adverse effects.
33
List the equipment required for performing PEEP.
* SMART BAG MO BVM * Diverter Valve * PEEP Valve * Advanced airway device (i.e. ET tube, Igel) * Oxygen tubing and an oxygen supply
34
What are the absolute contraindications for using PEEP?
* Pneumothorax (Tension/simple) * Hypotension (Systolic BP < 90mmHg for adults, < 70 + 2 (age) for children) * Acute asthma/chronic obstructive pulmonary disease
35
What are the physiological effects of PEEP?
* Increases functional residual capacity (FRC) * Prevents airway collapse * Reduces ventilation-perfusion mismatch
36
What are some possible complications of PEEP?
* Barotrauma * Increased physiological dead space * Decreased preload * Increased intracranial pressure (ICP)
37
What is the difference between physiologic PEEP and supraphysiologic PEEP?
Physiologic PEEP is 3 to 5 cmH2O, while supraphysiologic PEEP is at higher levels.
38
List the hemodynamic effects of PEEP.
* Reduced venous return to the right ventricle * Increased right ventricular after-load * Redistribution of cardiac output * Diminished perfusion of stomach, pancreas, and thyroid * Reduced hepatic artery flow
39
Fill in the blank: The ideal amount of PEEP applied prevents the collapse of alveoli while causing minimal _______.
barotrauma
40
What is the maximum amount of PEEP that can be adjusted according to the training guidelines?
10 cmH2O
41
What is the first step in the assembly of the diverter and PEEP valves onto the SMART BAG MO?
Inspect the diverter and the PEEP valves for defects and functionality.
42
Describe the steps to attach the PEEP valve to the diverter valve.
Fit the PEEP valve snugly over the exhalation port of the diverter valve after securing the diverter.
43
True or False: PEEP is indicated for patients with SpO2 < 85% despite appropriate therapies.
True
44
What does PEEP help to prevent in mechanically ventilated patients?
Airway collapse
45
What should practitioners do if they cannot achieve a pass mark on the self-assessment?
Review the content until comfortable and contact an educator for assistance if needed.
