Precision Medical EasyPulse POC - Overview

The Precision Medical EasyPulse PM4150 makes it simple for oxygen patients to receive oxygen therapy. The battery can last up to 4.7 hours, allowing users to use it while traveling or on the go. This portable oxygen concentrator weighs 6.6 pounds, so it is highly portable. There is even a user-friendly control panel that helps patients monitor their battery life, oxygen settings, and more. 

Precision Medical uses Vacuum Pressure Swing Adsorption (VPSA) technology to regenerate the sieve beds. Having clean sieve beds is beneficial to having a high oxygen purity level. Additionally, this POC includes Controlled Minute Volume (CMV), which is therapeutic oxygen delivered to patients in the first third of the inspiratory phase regardless of breath rate to offer maximum efficiency.

EasyPulse POC - Flow Settings

The Precision Medical PM4150 provides oxygen therapy in pulse doses. Pulse dose allows for oxygen to only be delivered during a user’s inhalation. This extrends the battery life and the overall lifespan on the POC. The PM450 has five pulse dose settings and can deliver oxygen from 240780 mL/min. Pulse dose settings should only be changed if it is recommended by your healthcare provider. 

To change the pulse setting, press the number button of the setting you need to change it to. An LED light will light up as a patient gets their oxygen delivered to them. To ensure best performance, it is not recommended to use longer oxygen tubing or a nasal cannula greater than 7 feet long.

Precision Medical EasyPulse POC - Battery Duration

The Precision Medical PM4150 can last for up 4.7 hours at a pulse dose setting of 1. If you combine that with the optional external battery pack, this POC can have a battery life of up to 9.4 hours.

Oxygen patients are able to monitor their battery life on the top-right corner of the display. When the POC gets to 15% charge, the LED battery indicator will turn red and the machine will beep once every minute. When the POC gets to 5% charge, the machine will beep every 20 seconds and the LED light will start blinking. The beeping will stop when the machine gets connected to an external power source. 

The PM4150 concentrator comes with both AC and DC power cords. Both will charge the internal battery while the device is plugged in.

EasyPulse POC - Ease of Access

Precision Medical EasyPulse portable oxygen concentrator’s control panel consists of only one button. The button is what turns the device on and off. There is also a rotating knob that is used to set the oxygen flow. These easy controls with LED light included  make it simple for any user to operate and troubleshoot their device. 

Precision Medical Oxygen Concentrator - Small Frame and Lightweight

The PM4150 weighs less than 7 pounds with the internal battery and is one of the lightest machines on the market. Its also small in size, with the dimensions being 10.1in x 6.5in x 4.5in.

Easypulse Oxygen Concentrator with CMV Technology

Precision Medical EasyPulse POC - Versatile
