Limits of Pressure-Control Ventilation: a Introduction to the Mid-Frequency Simulator

In respiratory therapy school I was never taught about the various mathematical models of pressure-control ventilation (PC-CMV) and we probably only had a hour lecture on respiratory time constants. In clinical rotations PC-CMV was seldom used and had a bad reputation only being used on the sickest patients. This was due to the practice of utilizing  inverse-ratio ventilation in treating patients with ARDS and  serve hypoxia, which led to the administration of neuro-muscular blocking agents and poor outcomes.

Even today many practitioners are unfamiliar with the most versatile mode of ventilation (PC-CMV) and do not know how to optimize the settings. If one wants to have a understanding of the advance modes of ventilation, PC-CMV is were to start.

New Course: Build a Ventilator Simulator

My new course "Build a Ventilator Simulator" is available at Udemy.

No it is not building the simulator with LEGO's.

It is for anyone who has wanted to build a simulator without programming experience, using MS Power Point & Key Note.

Assessment of Collateral Circulation of the Hand via Pulse Oximetry

The assessment of collateral circulation of the hand is performed often by surgeons, anesthesiologists, and Respiratory Care Practitioners (Cook, L, 2001; Galvin and Jones, 1989; Gerhring et al, 2002; Raju, 1986; Van de Louw et al, 2001) and Wisely and Cook, 2001). 

Surgeons may use this evaluation before performing a radial artery harvest for coronary artery bypass surgery, Anesthesiologists assess collateral circulation of the hand before arterial cannulation and Respiratory Care Practitioners check the collateral circulation before performing radial artery sticks for blood gas analysis. Each health care professional assesses collateral circulation of the hand for a different reason; however, they all primarily use the same evaluation technique.

The Global Medical Education Project (GMEP) has been developed by the team from "Life in the Fast Lane". This is a exciting resource that provides free open source medical education.

This is a social network site that allows members to view & submit content that is related to medicine. 

I myself  a member and contributor to this project have uploaded a large amount of media to be freely viewed.

Using the Quasi-Static Pressure/Volume Curve to Identify Optimal PEEP & Recruitability

             

In previous post I mention evaluating the static P/V curve to set P-High when using Airway Pressure Release Ventilation (aka. APRV, BiLevel, BiVent) and to set optimal PEEP.

Another advantage of analyzing the static P/V curve is to identify if the patients lungs are recruitable. If they are not recruitable, then they will most likely not respond to higher levels of PEEP or placing them on APRV. 

The above video demonstrates the difference between recruitable & Non-recruitable lungs.
