Perioperative Screening

MediPines AGM100® Respiratory Monitoring System

Pre-Surgery Evaluations

Avoid intra-operative and postoperative complications by knowing which patients have impaired gas exchange before they ever hit the operating table. The MediPines Gas Exchange Monitor® provides an objective measure of pulmonary gas exchange inefficiency (Oxygen Deficit) ideally suited for high throughput environments, such as the pre-operative evaluation area. The AGM100® is ideally suited for pre- and post-operative environments due to its portability and rapid measurements.

Post-Surgical Monitoring

The AGM100® provides an objective and repeatable measure of pulmonary gas exchange that allows for postoperative monitoring of pulmonary complications, that without early intervention, can be costly. Post-operative pulmonary complications are common and occur in 22% of high risk patients and in 5-10% of patients undergoing non-thoracic surgery.*


“Quite frankly, over 15% of our surgical patients have COPD and many more don’t know they have respiratory issues. That is why we want to use the MediPines Gas Exchange Monitor (AGM100®) here to fast screen these patients, pre-surgery…”

Postoperative Pulmonary Complications

Clinicians need an effective tool to help identify potential high risk patients. Current tools, such as pulmonary function tests (PFT) can be useful but insufficient in identifying degree of gas exchange inefficiency. A 2016 study of 1412 patients undergoing cardiothoracic surgery showed that pulmonary function tests (FEV1 and FVC) and their corresponding lung disease classifications (present in 751 of the cases) were not helpful in predicting post operative complications such as, respiratory failure (RF), prolonged postoperative length of stay (PPLS), and death.  Rates of complications between patients that had a PFT compared to those that did not were not statistically significant.  Additionally, current risk scores were only moderately predictive.*


MediPines Gas Exchange Monitor

The MediPines Gas Exchange Monitor® was developed to provide a fast, objective, measure of pulmonary gas exchange in multiple care settings:

    • Emergency
    • Perioperative screening
    • Office visits
    • Outpatient clinic
    • ICU
    • Extreme physiology & more

Postoperative Pulmonary Complications

“Postoperative pulmonary complications (PPCs) are common, costly, and increase patient mortality. Changes to the respiratory system occur immediately on induction of general anesthesia: respiratory drive and muscle function are altered, lung volumes reduced, and atelectasis (partial collapse of the lung muscle) develops in > 75% of patients receiving a neuromuscular blocking drug.”*
