Conversion formulas and mech vent
| Question | Answer |
|---|---|
| Cylinder Duration | Duration =2200 x factor/total flow E=.3 G=2.41 H=3.14 |
| Calculating FiO2 (home) | (.21 x airflow) + (O2 flow) / total flow |
| Liquid Cylinder Duration | Reservoir wght x 342 / liter flow |
| Calculating Flow in L/Min | Flow rate (L/Sec) = Vt (tidal vol in ml) / I-time (in sec) Convert ml to L and Convert Sec to Min |
| Calculating Vt (Tidal vol) | Vt = Flow Rate (L/Sec) x I-time (sec) Convert L to ml for tidal vol |
| Calculating I-time | I-time(sec) = Vt (L)/Flow Rate (L/sec) Convert ml to L on Vt |
| Calculating I-time when rate & I:E are unknown | Respiratory cycle time / total parts of I:E = necessary I-time Means same as TCT / TP = I-time Resp cycle time = RR bpm must convert Min to Sec |
| Calculating Corrected Vt | Exhaled Vt - Compressed Vol = Corrected Vt; Where Compressed Vol = (PIP - PEEP) x circuit compliance Must end up in ml |
| Calculating Compressed Volume | Comp Vol = (PIP - PEEP) x circuit compliance |
| Calculating Mean Airway Pressure | MAP = PIP (I-time/TCT) + PEEP (E-time/TCT) Remember to add I-time and E-time to get TCT |
| Calculating Time Constant (Kt) | 1 Kt = Compliance (L/cmH2O) x Resistance Remember 3 Kt is required for 95% of Vt to exit lungs Remember convert ml to L |
| Calculation E-time to achieve RR | E-time = 60/desired rate = TCT then TCT - I-time = E-time |
| Calculating % Solution | % Solution = Solution wgt (g) / Solvent Vol (ml) x 100 Remember to convert mg to g |
| Calculating BiCarb dosage | HCO3 dosage = [Pt wt (kg) x base deficit] x .03 Remember: convert mg to g and g to kg |
| Calculating Oxygen Index (OI) | OI = MAP x FiO2 / PaO2 x 100 |
| Goals of Mech Vent | Normalize & maintain ABG's; Prevent iatrogenic complications (ie: Barotrauma, infection, sedation); Support pts resp needs |
| Neonatal Ventilation | Normally Time Cycled / Pressure Limited |
| Pediatric Ventilation | Normally Volume Cycled |
| Neonatal mech vent settings | Need PIP, PEEP, RR, I-time, MAP, Vt; Must have readings of Vt and Ve |
| Most neonatal vents are _______ ________/_________ ___________ vents | Time cycled / pressure limited (limited by PIP you set) |
| What is initial PIP for? | To achieve good chest excursion |
| What does excessive PEP cause? | Hyperinflation & barotrauma; ie: PIE, pneumothorax, pneumomediastinum, pneumocardium, BPD) |
| When controlling pressures, ______ directly affects _____ and _____ | PIP; Vt and MAP (Paw) Ie: ↑ PIP ↑ Vt ↑ PIP ↑ PaO2 & ↓ PaCO2 by ↑ Ve (PIP also ↑ MAP) |
