INTRODUCTION. The pulmonary artery catheter (PAC; Swan-Ganz or right heart catheter) can be used for a variety of clinical purposes. Interpreting hemodynamic data from PACs is important for the diagnosis and management of a range of conditions including shock and pulmonary artery hypertension ().The interpretation of hemodynamic values and pressure …

Part of this controversy may be related to the incorrect interpretation of the data obtained from the pulmonary artery catheter. An understanding of the physiologic events responsible for the various waveforms may aid in the correct interpretation of data obtained with the pulmonary artery catheter. By recognizing the abnormal patterns of waveforms, specific etiologies for …

After observation of properly formed pulmonary artery waveforms, the RN can obtain the pulmonary artery wedge pressure. Proper inflation techniques are important because overinflation of the balloon may cause overdistention of the pulmonary artery, which can cause rupture of the vessel. The balloon should always be inflated slowly while the waveform tracing …

FIGURE 23.9 Mitral stenosis with simultaneous left ventricular (LV) and left atrial (LA) waveform tracing. Note the difference between using pulmonary capillary wedge pressure and LA pressure in gradient calculation given the delay in transmission of the LA pressure across the pulmonary vasculature (shaded graphic in black seen in Figure 23.8). This can lead to a …

Simultaneous absolute pulmonary artery wedge (Ppw) and esophageal (Pes) pressure tracings with electrical subtraction of Pes from Ppw in. a patient with airway obstruction ( left) and plot of changes in Pes and Ppw in 10 such patients ( right). High Ppw suggestive of left heart failure returns to normal.
5: The atrial waveform | Thoracic Key
https://thoracickey.com/5-the-atrial-waveform/
The left atrial waveform can be measured directly by transeptal atrial puncture or more commonly indirectly via a balloon‐tipped pulmonary artery catheter. In most cases, the pulmonary capillary wedge pressure (PCWP) accurately reflects mean left atrial (LA) pressure; however, the pressure wave deflections are delayed and damped on a PCWP tracing compared …
Interpretation of Hemodynamic Waveforms | Anesthesia …
https://aneskey.com/interpretation-of-hemodynamic-waveforms/
The pulmonary artery waveform has a systolic pressure wave and a diastolic trough . A dicrotic notch due to closure of the pulmonic valve is occasionally seen on the terminal portion of the systolic pressure wave. Like the right atrial v wave, the pulmonary artery systolic wave typically coincides with the T wave of the ECG (see Fig. 28-7). The pulmonary artery …
