HeartMate III Left Ventricular Assist System Instructions for Use

6. Determine the minimum Fixed Speed:

a. Starting from the current Fixed Speed, lower the speed gradually to a value as low as 

possible without the patient experiencing signs of worsening heart failure. 
For example, shortness of breath or lightheadedness. 

b. Allow the patient to stabilize at each speed setting. 

IMPORTANT!  

Do not allow the Fixed Speed to drop below 3,000 rpm under any 

circumstances. 

c.

Reduce the speed until the aortic valve opens with each beat or the patient starts to 
become symptomatic. 

d. Record the patient’s current heart rate, blood pressure, and Pump speed. 
e.

Using echocardiography, record the patient’s left ventricular diameter and position of the 
septum.

7.

Determine the maximum Fixed Speed:

a. Starting from the minimum Fixed Speed (determined in Step 6), increase the pump speed 

gradually until echocardiography shows a flattening of the interventricular septum (or is 
clinically acceptable based on the echocardiographic evaluation). 

b. Record the patient’s current heart rate, blood pressure, and Pump speed. 
c.

Using echocardiography, record the patient’s left ventricular diameter and frequency of 
aortic valve opening.

8. Based on findings from the speed study, determine the optimum Fixed Speed, which usually 

falls midway between the minimum and maximum speeds. 

IMPORTANT!  

The selected speed may be adjusted based on clinical judgment regarding the 

need for periodic aortic valve opening and a palpable pulse. To accommodate normal shifts in 
volume and hemodynamic status, the Fixed Speed should generally be set at least 400 rpm below 
the maximum Fixed Speed determined previously. 

Low Speed Limit

The Low Speed Limit should be set at the lowest speed at which the Pump can run while 
maintaining patient stability. It is important to establish a Low Speed Limit that can sustain a 
patient safely. Establishing a Low Speed Limit will maximize the protective benefits during PI 
events or when the Pump is in Power Saver mode. 

In Power Saver mode, the System Controller slows the Pump speed to save power. If power is 
removed or fails, the System Controller provides 15 minutes of full power before entering 
Power Saver mode. Note that alarms cannot be silenced while the System Controller is in 
Power Saver mode.
