The PM50 Patient Monitor is a compact, portable device designed for continuous monitoring of blood pressure (NIBP) and oxygen saturation (SpO₂) in clinical settings such as hospital wards and community clinics. Below is a structured overview of its key features, performance, and specifications:

---

Key Features

1. Dual Monitoring Modes

   • Real-time monitoring of BP, SpO₂, and pulse rate (PR).

   • 24-hour ambulatory NIBP measurement with customizable intervals (5–120 minutes).

2. Data Management

   • Stores NIBP and SpO₂ data for up to 1,000 patient cases.

   • PC software for data review, trend analysis (graphs/charts), annotations, and report printing.

   • USB connectivity for data transfer between device and computer.

3. User-Friendly Design

   • 2.4" TFT color LCD with intuitive menu (English/Chinese).

   • Alarms for low battery, parameter limits, and errors.

   • Customizable patient information and case management.

4. Portability

   • Lightweight (<350g) and compact (128×69×36mm).

   • Powered by 2×AA batteries (3V DC).

Performance Specifications

NIBP (Non-Invasive Blood Pressure)

• Method: Oscillometric (upper arm cuff).

• Ranges:

  • SYS: 40–270 mmHg

  • DIA: 10–215 mmHg

  • MAP: 20–235 mmHg

• Accuracy: ±3 mmHg.

• Pressure Control: Automatic inflation + stepwise deflation.

SpO₂ (Pulse Oximetry)

• Range: 0–100%.

• Accuracy: ±2% (70–100% SpO₂).

• Weak Pulse Detection: Works at 0.4% perfusion (±4% SpO₂ error).

• Ambient Light Resistance: ±1% deviation vs. darkroom.

Pulse Rate

• Range: 30–250 bpm.

• Accuracy: ±2 bpm or ±2% (whichever is larger).
