Study Notes

Cardiovascular Measurements

PCWP: Pulmonary capillary wedge pressure, indicative of left atrial pressure.
PAOP: Pulmonary artery occluded pressure, often used interchangeably with PCWP.
Swanz-Ganz Catheter: A soft, flexible catheter used to measure pressures in the pulmonary artery.
PAWP: Pulmonary artery wedge pressure is equivalent to left ventricular end-diastolic pressure (LVEDP).
Normal PCWP: Ranges from 10-12 mmHg.
Normal CVP: Central venous pressure should be 4-8 mmHg.
Normal RVP: Right ventricular pressure is typically 20-30 mmHg over 0 mmHg.
Normal PAP: Pulmonary artery pressure measures 20-30 mmHg over 10 mmHg.

Respiratory Parameters

High Peak Inspiratory Pressure (PIP): Indicates increased airway resistance.
Plateau Pressure (Pplat): Determines lung compliance.
Normal I:E Ratio: A ratio of 1:2 is typical for healthy individuals; adjustments are needed for obstructive diseases.
I:E Ratio in Obstructive Disease: In patients with COPD or asthma, the ratio can expand to 1:3 or 1:4.
Normal PEEP: Positive end-expiratory pressure in ARDS ranges from 8-12 cmH20.

Ventilation Modes

Volume Control (VC): A method of ventilation that delivers a preset volume.
Pressure Control (PC): A ventilation mode that delivers a set pressure.
Assist Control (AC): Used for post-cardiac arrest, ARDS, and paralytic patients, targets tidal volume and can be initiated by the patient or the ventilator.
Synchronized Intermittent Mandatory Ventilation (SIMV): Allows patients to initiate breaths while ensuring minimum ventilation requirements are met.
Pressure Support (PS): Offers additional pressure during spontaneous breaths to aid in overcoming endotracheal tube resistance.

Ventilation Alarms

High Pressure Alarm: The most common alarm indicating obstruction, possible reasons include pneumothorax or coughing.
Low Pressure/Low Tidal Volume Alarm: Signifies inadequate volume delivery; check for leaks or disconnections.
High Respiratory Rate Alarm: Could indicate patient distress or equipment issues like kinks.
Apnea Alarm: Triggered by disconnection from the ventilator or lack of respiratory effort.

Air Medical Operations

Organizations: FAA (Federal Aviation Administration) and CAMTS (Commission for the Accreditation of Medical Transport Systems) govern air medical transport.
FAA Regulations: Federal Aviation Regulations (FAR) outline rules for various aircraft operations.
Top Causes of Air Med Crashes: Major contributing factors include pilot error, adverse weather, and nighttime operations.

Pilot Regulations

FAR 91: Covers regulations for non-commercial passengers and patients during flight.
Max Blood Alcohol Concentration (BAC): Legal limit set at 0.04 g/dL.
Hours from Last Drink to Flying: Minimum of 8 hours is required ("bottle to throttle").
Pilot Command: Refers to the "Pilot in Command" (PIC).

Crew Regulations

Medical Crew Duty Period: Set at 24 hours for medical flight crews.
Medical Crew Rest Period: Minimum required rest period of 8 hours.
Pilot Duty Period: Max of 12 hours for pilots, ensuring fatigue management in flight operations.
